The rose garden of good government seems far away

They never promised us – nor did we realistically expect – a public sector in SA that performs as well as they seemingly do in say Scandinavia. What we have in SA is however widely recognised as an almost complete failure. The government offers little defence of its current practice  – only long agendas for reform. Which raises the question – why does the SA public sector perform quite so badly?

One feature of the SA public sector deserves notice. The financial rewards it offers its officials – salaries, medical and pension benefits and secure tenure, are clearly very attractive when compared to the private sector. Such that there is very little movement from public to private employment. The regret of the government is that the limited flow of taxes has provided minimal scope for raising the numbers of teachers, nurses or humble pothole fillers. For those that have jobs are given more– in the form of regular above inflation increases in their salaries. While the hospital wards and classrooms become increasingly crowded and the roads impassable and the lights are off rather than on.

Given the superiority of public employment and given the abject failure of the economy and the labour market to absorb many more men and women of working age into formal employment, the issue of just how the favoured jobs in the public sector are allocated becomes especially important to understand.  Recruiting strictly on the merits of potential recruits is clearly not the overriding modus operandi in SA.  Observing racially prescribed quotas are one of the binding constraints. And a key performance indicator by which institutions and their leaders are measured.

ANC Cadre employment is another important objective of government employment policy. That notwithstanding the implications drawn by the Zondo Commission of Enquiry, is a practice that has not been disavowed by the President.  And yet should cadre deployment not be the overriding mission and practice of the HR specialists in government, nor merit their North Star, the tempting gap between the supply and demand for highly prized employment opportunities with governments, of all kinds and agencies in SA, is very likely to be filled by unorthodox procedures in exchange for a finder’s fee or some equivalent. The opportunity to capture some of the ongoing rents will not have escaped those with bargaining power or influence. Historically in other regimes, shop-stewards, backed by Unions with the power to strike down essential services, have exercised such powers when allocating limited and well-paid jobs as on the Docks or the construction sites or among the waste removers. Nepotism may be another description for it.  As they say nature, including homo economicus, abhors a vacuum. 

If employment in the public sector is not explained by objective measures of ability to perform important functions – by qualifications carefully vetted and by psychometric measures of potential etc objectively administered. And when advancement is based upon years of service, and not key performance indicators (KPI’s) of the kind common in the private sector, how are the officials so appointed, likely to behave, all the way up the hierarchy? As may be presumed of all in the workplace, they will behave mostly in a self-interested way.  You do get what you pay for.

Absent any link between merit, performance and reward, accepting the grave responsibility for carefully spending hard earned taxes, or of being a conscientious public servant for its own reward, is much less likely to be the outcome. Denying the capture of highly valuable contracts with government, opening the tender honestly, whistle blowing when procurement rules are flaunted, becomes essentially quixotic, even dangerous. Going the extra mile when nursing or teaching or policing all becomes much less likely.  After all, where else is the citizen to go for a permit or essential documentation, or the poor to go for schooling or medical care or protection?  They are easily treated as supplicants rather than valuable customers. Producers rather than consumer’s interest will prevail.

The case for meritorious public service is essential to the purpose of good government. Introducing much more of it in SA will however have to overcome powerful interests in the established favour and crony driven system. It will take the recognition, resentments and ultimately the votes of the victims of poor service to do so.

Are movements in the ZAR/USD exchange rate a mystery?

Brian Kantor and David Holland

A great deal of commercial, domestic, and speculative energy is spent pondering the future of the rand (ZAR). The foreign exchange value of the rand will remain highly variable and unpredictable. The best prediction for tomorrow’s exchange rate is today’s rate but with a high level of variance that increases with time. As in the past, the rand is unlikely to be a one-way bet. It will experience periods of negative and positive turbulence. On average, persistent rand weakness is expected in the currency markets due to the higher inflation and sovereign risk of South Africa relative to the US dollar (USD) and other hard currencies. The rand cost of a US dollar is priced to rise at an average rate of 5.5% p.a. over the next five years and by about 4.5% this year. Yet, for all its volatility, changes in the foreign exchange value of the rand can be almost fully explained by but two persistent influences on its value. These are the exchange rates of other emerging market currencies with the dollar and the dollar prices of industrial metals that SA exports. 1

Since 2010, daily movements in the EM currency basket explain 54% of daily movements in the ZAR/USD exchange rate. This is a highly significant association. If you had a crystal ball that foretold future EM basket to USD rates, you could make confident and profitable bets on the trajectory of the rand’s exchange rate. Unfortunately, exchange rates are random walk processes that are impossible to precisely predict. And commodity prices also follow a random walk process. Your best guess for tomorrow’s ZAR/USD exchange rate is today’s rate plus or minus 1% (and ±2.2% if you’re looking a week ahead).

Knowing why the rand behaves as it has may however not help much to predict where it is heading. Forecasting the USD/ZAR demands an accurate forecast of the dollar value of other EM currencies and metal prices. A clearly formidable task. A strong dollar, as measured vs its developed economy peers, will clearly force EM and ZAR weakness and probably also weigh on metal prices, when expressed in USD – and vice versa. Though the major force acting on metal prices will be the state of the Chinese economy- the major destination for industrial metals – and so another known unknown with relevance for the ZAR.

The other forces acting on the rand are South African specific events. Political shocks and own goals that move the rand irregularly and unpredictably one way that then may be reversed. These shocks account for up to 46% of the movement in the rand relative to other emerging markets.

This is where wise economic policy and effective implementation of those policies can positively influence the exchange rate. The persistently weaker bias of the rand when compared to not only the US dollar, but also when compared to other emerging market currencies, is due to the failure of the South

African economy to deliver meaningful growth and attractive returns. The rand is riskier than the emerging market basket to a significant degree. A drop of 1% in the EM basket typically translates into a 1.5% drop in the rand. Government’s job is not only to shoot fewer own goals, but to convince through positive coordinated action that South Africa is not significantly riskier than other emerging markets. The potential gains are a less risky rand, a lower cost of capital, greater investment, job creation, and more wealth for the country to share.

Some Basics of Supply and Demand

We all know that market determined prices reconcile supply and demand. Higher prices discourage demand and encourage supply. What is true of an individual price is true of all prices on average, as represented by a Consumer Price Index(CPI) That prices generally tend to rise with increased demands or reduced supplies and vice versa seems obvious enough.

Higher prices discourage demand and encourage supply. That prices generally tend to rise with increased demands or reduced supplies and vice versa seems obvious enough. But the supply and demand for all goods and services are not determined independently of each other. The supply of all goods and services produced in an economy over a year is equivalent to all the incomes earned producing the goods and services that year. The value added by all producers (GDP) is equal to all the incomes earned supplying the inputs that produce output. Incomes are received as wages, rents, interest, dividends, taxes on production and what is left over, the profits or losses for the owners after all input costs have been incurred.

Produce more, earn more and you are very likely to spend more. The economic problem, not enough of everything, too little income, is surely not the result of any reluctance to spend on the necessities or luxuries of life. The problem is we do not produce enough, earn enough income to spend really more.

Extra demands can be funded with debt. Yet for every borrower spending more than their incomes, there must be a lender saving as much. Matching financial deficits with financial surpluses, is the essential task of financial markets and financial institutions, and may not happen automatically or seamlessly. There may be times when the demand for credit and the spending associated with it may run faster or slower than the supply of savings. If so incomes and output may increase temporarily above or below long-term trends. We call that the business cycle. Interest rates (yet another price) may be temporarily too low or too high to perfectly much the supply of and demand for savings. But such imbalances must sooner or later will run up against the supply side realities, the lack of income.

There is a further complication. The supply of goods and service is augmented by imports. And demand includes demand for exports. In South Africa both imports and exports are each equivalent to about 30% of the economy, making a large difference to supply and demand. But the prices of these imports and exports are not set in South Africa. They are set in US dollars and translated into rands at highly unpredictable and generally weaker exchange rates. The prices paid for imports and exports affect average prices. And they mostly push the averages higher. It has been the case in SA of a weaker exchange rate leading, equivalent to a supply side shock, and prices following.

And the rand is still expected to depreciate against the dollar by more than the difference between SA and US inflation. The bond market expects the rand to weaken against the USD by an average 7.3% p.a. over the next ten years, being the spread between RSA bond yields (12%) and the US yield(4.7%) While the difference in inflation expected in SA (7.2% p.a.) and in the US (3.2% p.a) over the next ten years is much less, only 4.8% p.a. according to the break-even gap between vanilla bond and inflation protected bond yields.

Lenders to the SA government remain suspicious of SA’s ability to grow fast enough to raise the taxes  that could sustain fiscally responsible policies. That is the government will not avoid resorting to funding expenditure with money supplied by the central and private banks. A sure source of extra demands without extra supply that leads to ever higher prices as it does persistently in most African countries.

There is little monetary policy and short-term interest rates can do to strengthen the rand and bring inflation down further against this backdrop. That is without resulting in too little demanded and even less supplied than would be feasible. That in turn bringing  still slower growth more fiscal strain, higher borrowing costs and a still weaker rand- and higher prices.  The call is not to inhibit already depressed demand but for economic policy reforms that would stimulate the growth in SA output and incomes enough to change the outlook for fiscal policy, the exchange rate and inflation.

Building Brics – opportunity beckons

The group of countries that will make up the enlarged BRICS, Argentina, Egypt, Ethiopia, Iran, Suadi Arabia and the UAE have little in common other than a deep suspicion of the motives of the US and its close allies. A state of mind also shared by left wing opinion everywhere including in the US itself. If the unlikely combination of kingdoms, autocracies and genuine democracies is to become more than a another talking shop with an anti-West bias, then it should take an important lesson from the economic development of the US and Europe.

What has been of great benefit to the US and to Europe, since it established a common European market and Euro are their highly significant common currency areas.  The same money is used everywhere in the US and Europe as a medium of exchange and a unit of account. Thus unpredictable rates of exchange when buying or selling goods and services across frontiers are avoided, as are the direct costs of converting one currency into another- usually converting US dollars -into the domestic money.

Trade and financial flows between the states of the US and now of Europe is greatly encouraged by what is a fixed exchange rate regime within a common market, also free of protective of domestic industry tariffs or discrimination against foreign suppliers, by regulation. As it does incidentally when transactions of one kind or another take place within any country. The important trade between Gauteng and the Western Cape for example is facilitated by prices set in the rand common to both.

In the nineteenth century when which international trade and finance first flourished and economies came to benefit from wider markets for their goods and labour, and the ability to realise productivity and income enhancing economies of scale, currencies were mostly linked by fixed rates of exchange.  The link was the ability to convert the different monies, if necessary, into gold at a fixed rate. And the issuers of different monies made sure to maintain convertibility by protecting their balance of payments through adjusting domestic interest rates. If gold generally flowed out interest rates could be raised to conserve and attract gold reserves and vice versa. Provided the commitment to currency convertibility was fully credible, the extra interest received would balance the payments by attracting or retaining capital.

A modified fixed exchange rate system was re-established after the second world war with the US dollar as the reserve currency- but dollars that could be converted into gold at the request of other central banks. This commitment was abandoned unilaterally by the US in 1971 and market determined exchange rates, with the still dominant US dollar, became the norm. Highly variable rather than predictably fixed exchange rates have become the unsatisfactory order of the day. The rates of exchange of other currencies with the dollar, both in money of the day terms and when adjusted for differences in inflation of different currencies have varied very significantly – and unpredictably- damaging volumes of international trade and real investments.

It has not been a case of exchange rate moves levelling the playing field for traders in goods and services- so maintaining purchasing power parity in the face of differences in inflation rates across trading partners. Rather the exchange rates have adjusted to equilibrate independent flows of capital – large and reversible flows – in search of better risk adjusted rates of return- to which inflation then responds. Weaker exchange rates lead to more inflation and vice versa. Without stable exchange rates, controlling inflation in the face of capital withdrawals and a suddenly weaker exchange rate with the US dollar can become a severe interest rate burden on the domestic economy – as South Africa demonstrates.

The enlarged BRICS could establish fixed exchange rates between each other to promote trade and investment. They might usefully adopt a Chinese standard- that is offer convertibility of their own currencies into Renminbi at fixed rates. And rely on the Bank of China to manage the float of the crucial rate of exchange of Renminbi into US dollars, as it now does.

Who wants to be a billionaire (in rands)?

Peter Bruce has pointed to something in the Stellenbosch water of the late sixties and seventies that produced so many rand billionaires. They would not have been inspired by some professor of economics enthusiastic about the power of free markets telling them to do good for the nation by getting rich. They are much more likely to have been told the opposite. Told why markets will not work nearly well enough and that any faith in entrepreneurial flair would be entirely misplaced. I have yet to meet a Stellenbosch economist who believes that an economy is best left guided by the forces of competition.

And one can perhaps understand why. The interventionist economic policies, long adopted in SA before 1994, clearly helped to completely transform the economic and educational status of the Afrikaner nation, in a generation, both absolutely and comparatively. They might have done even better with freer markets, but this would not have been self-evident. By every measure, the Afrikaner, on average lagged well behind the standards enjoyed by the average English speaker in the nineteen thirties. By the sixties they had caught up. Even, as the average incomes of both communities had improved significantly.

Many of the best and brightest Maties sought their futures working for the state and its agencies. The case for ownership by the state of some of the commanding heights of the economy, steel, electricity, railways and ports was taken as a given and not contended. And they were not, with few exceptions, seen as the path to private riches through corrupted procurement and biased tenders to which SOE’s are so conspicuously vulnerable.  Nationalism and strong sense of community may have had something to do with this restraint.

Perhaps with Johan Rupert a fellow student, the example of the ineffable Anton Rupert was the inspiration. He who went door to door selling shares in his fledgling enterprise that was to take down a powerful near monopoly of the cigarette market in SA. The billions of the Stellenbosch cohort, like those of the Ruperts, were made in a conventional way.  By competing successfully with established businesses for their customers and executing better combined with intelligent financial engineering that is always the leveraged and risky path to great wealth. Taking the opportunity provided by contestable markets is characteristic of successful, dynamic economies.

Peter Bruce is quite wrong to assert (Business Day July 27th) That Stellies route to billions is gone — and it’s undesirable. Apartheid-era billionaires can’t be reproduced in today’s democratic conditions.

It would be highly desirable were the South African economy to produce a few more billionaires in a similar old-fashioned way. By taking on established interests, winning market share and reviving businesses that have lost their way and are now valued at far below what can be regarded as their replacement cost. With the help of value adding, better designed financial structures and appropriate incentives for managers based on what really matters, return on all capital employed. It seems to me the opportunity to acquire great wealth in rands and dollars is as open, perhaps more open than it has ever been given current market pessimism.

The aspirant billionaire will not have to rob the taxpayer to get rich – though it is still unfortunately the most obvious route. Yet more than a few new billionaires are hard at work proving my point that Bruce may not have noticed from his rural retreat.

Though admittedly a billion rand today is a lower target, worth a lot less than a billion in 2000 – about 35% as much, after SA inflation. To compare purchasing power in US dollars, you might do as the IMF does – divide billions of rands by 7 not 19 to convert SA GDP into purchasing power dollar equivalents. If the rand just compensated for differences in SA and US inflation since 2000, a dollar would cost R13.5 and a billion rand would buy the equivalent of USD74m – more than nickels and dimes.

Some Identity Economics

There is a certain balance of payments (BOP) outcome.  That the dollar payments and dollar receipts in the currency market will strictly balance over any period- an hour, day quarter or year. The exchange rate and interest rates will continuously adjust to make it so- to equalize supply and demand for dollars and other currencies traded. And it is a very good idea for the authorities not to intervene in or attempt to influence this market determined exchange rate with interest rate adjustments. Or to directly control demands for or supplies of foreign currencies to achieve a temporarily better, perhaps less inflationary rate of exchange. A shadow market will emerge to siphon off undervalued dollars, leading to an official scarcity of dollars. Making it very difficult to do normal helpful income enhancing business across the frontiers and discouraging to foreign investment so important to any economy. As MTN knows only to well from its experience in Nigeria.

Another BOP relationship will also always hold. The current account of the BOP- that measures payments and receipts for imports, exports and the flows of dividends and interest paid or received by South Africans, will always be matched equally and oppositely by what are measured as flows of capital over the exchanges. A current account deficit will always be matched by a capital account surplus of the same amount and vice versa. There is no cause-and-effect relationship implied by this identity.  The current account does not determine the capital flows – any more than the capital flows determine net flows of foreign trade, interest, and dividend payments. It is an accounting identity.

The capital and current accounts- an identity, identified.

Over most years the current account of the SA balance of payments has been in deficit. Exports of goods and services almost always exceed imports – generating a consistently positive balance of trade (BOT)  While the deficit on what might be described as the asset service account, dividends and interest payments, almost always exceeds dividend and interest received by enough to exceed the positive BOT. The interest and dividend yields on SA liabilities much exceeds the dividend and interest yield on SA assets held abroad. But between 2020 and 2022 South Africa ran current account surpluses and exported capital on a significant scale. So much so that the market value of SA assets held offshore now exceeds that of the market value of foreign owned assets in SA. This was not good for the South African economy.

There is a National Income Accounting Identity to help make the point. The current account deficit also equates to the difference between Aggregate Incomes that are equal to Aggregate Output (GDP) and Total Expenditure on final goods and services (GDE) It is also by definition the difference between Gross Savings and Gross Capex. Post Covid, Gross Savings, almost all in the form of cash retained by the corporate sector, held up better than Capex and capital – from a capital starved economy – flowed out.

Both the ratio of Gross Savings – and Capex to GDP can be regarded as unsatisfactorily low in SA. The opportunity to raise the savings rate seems limited, given low average incomes. However, the opportunity to raise the rate of capex to GDP and to attract foreign capital to fund income growth encouraging capex and the accompanying larger current account deficits is always open. SA must be able to offer faster growth and the accompanying higher expected returns, to attract more foreign capital and to retain a greater share of domestic savings.

Supply side reforms are urgently needed for the SA economy. We all know what they are. Demand will keep up with supply automatically. Extra Supply – extra incomes earned producing more goods and services- creates its own demands. Yet until the economy can deliver more growth and better returns, the best we can do with our savings is to invest them abroad. (including buying shares of companies listed on the JSE that do almost all of their business outside the SA economy) Without such opportunities, the pension and retirement funds, upon which we depend for our future income, would be in a truly parlous state.

The Fed has rescued the Rand

The rand has recovered strongly this month – by about 7% against the US dollar, and has performed similarly Vs the Aussie dollar and an index of EM currencies. The rand had weakened through much of 2023. It weakened by a further 3% when the SARB increased rates unexpectedly sharply by 50 b.p. on May 25th. Since June 1st the ZAR has recovered – as interest rates in SA have fallen away. arply.

Long term RSA bond yields have declined significantly and helpfully by between 50 and 70 basis points this month. The Yankee Bond, a five year dollar denominated claim on the RSA, now yields a lower 6.4% p.a. compared to the 7% p.a. offered on June 1st. Moreover, the spread between the RSA dollar bond and a US Treasury of the same duration has narrowed significantly from 3.6% p.a to 2.8% p.a. This interest rate spread provides a very good indicator of the risks of default attached to SA bonds. More important perhaps for the direction of the rand and the economy has been the recent inflection in short-term interest rates. When the SARB raised rates on the 25th May, the money market, as represented by the forward rate agreements of the banks, immediately predicted a further one per cent hike in short rates over the next six months. The SARB is now expected to be much less aggressive. The market is now expecting short rates to rise by a quarter per cent.

Why have surprisingly lower short term interest rates helped the rand as surprisingly higher rates clearly weakened the rand last month? There is much more than coincidence at work here. Higher short-term rates – higher overdraft and mortgage rates- combined with the higher prices that follow a weaker rand – are expected to further depress spending in SA and the growth outlook for the economy. The weaker the outlook for the economy, the weaker the growth in incomes before and after taxes, the more government debt is likely to be issued. And the graver becomes the eventual danger a of a debt default. For which still higher interest rate rewards have to be offered to investors to compensate them for the additional risks implied by a deteriorating fiscal condition. These higher interest rates then raise the cost of capital for SA business – making them still less likely to undertake growth encouraging capex.
The Reserve Bank is ill advised to react to exchange rate shocks in ways that further threaten the growth outlook – and can prove counterproductive by weakening the rand that then lead to still higher prices. Interest rate increases make sense when excess spending – excess demand – is putting pressure on prices. Which is not the case for the SA economy today. The right response to exchange rate shocks is to ignore them as their temporary impact on the price level falls away. Absent any additional consistent pressure on prices from the demand side of the economy, over which the SARB will always have strong influence. The notion of self-perpetuating inflationary expectations, as promoted by the Reserve Bank when explaining its interest rate reactions to a weaker rand, is supported neither by evidence nor is it consistent with self-interested economic behaviour. It is poor theory and even poorer practice.
But this leaves open the question- why then have interest rates come down in SA? The answer can be found offshore. The Fed has found good reason not to push its own rates higher. The pause on rate increases in the US became widely expected and was confirmed yesterday gives the SARB even less reason to raise its own interest rates. The Fed by dealing effectively with a surge in inflation (which has not been self-perpetuating) has improved the outlook for interest rates, the SA economy and the rand.

Update on US Inflation – to May 14th 2023.

Both CPI (4.0%) and PPI headline inflation fell more than expected in May. Monthly moves were low – 0.2% for CPI and negative for PPI. The only proviso was the elevated rate 0.4% m-m for core CPI- CPI excluding energy and food. But core has a very large rental weight- over 40% which was up 8% y/y – but rentals are clearly heading lower and core may not be the most useful leading indicator for CPI – PPI- now strongly lower may do much better in predicting CPI.
The Fed paused but member dot plots indicated further increases to come. But the Chairman says the Fed will remain data dependent and my view is that the Fed panic about inflation is over. Because demand pressures on inflation are largely absent- thanks to higher interest rates and negative growth in money supply and bank credit. The global pressure on interest rates in SA is therefore abating. As discussed in my commentary above

What can help the Rand and the economy?

Graham Barr and Brian Kantor

16th May 2023

In early 1980 the Rand reached a peak of 1.32 US$ to the Rand; yes, the Rand then bought more than one dollar! This was the time of a very high gold price of $820 per oz. when Russia invaded Afghanistan and WW3 looked like a real possibility. It was but 35 dollars an ounce in 1970. Things have not been as rosy on the exchange rate front since. The exchange rate is currently around 19.2 Rand to the $. This means that in purely nominal terms the Rand is currently 1/25th (against the dollar) of what it was in those heady days of 1980! If the ZAR merely adjusted for differences in SA and US inflation since 2000 the dollar would now cost less than R13. In a relative sense- the ratio of the market to the Purchasing Power Parity was only wider in 2002 when the ZAR was nearly 80% undervalued. At current exchange rates it is about 50% undervalued. Or in other words the rand buys roughly 50% less in NYC than it does in SA as SA visitors will testify. The great deals will now be realised by tourists to SA –until the rand sticker prices in the stores and on the menus are marked higher. See figure 1

In the seventies as the gold price took off- more in USD than ZAR, SA was the largest gold producer in the world and gold mining was hugely lucrative for shareholders in the gold mines and for the SA government who collected much extra revenue from taxes, and royalties paid by the gold mines. Platinum mining was only then getting going and subsequently got a huge boost from the widespread use of catalytic converters in the exhausts of motor vehicles. Coal exports got going after the construction of the huge export terminal at Richard’s Bay, and the rich Sishen iron ore deposit was still to be exploited.

South Africa is now merely the eighth largest producer of gold in the world, producing but a sixth of the gold delivered in 1970. And gold production is now a relatively small part of the South African economy that in the seventies accounted for 60% of all exports from SA and about 16% of GDP. The link between the gold price and the exchange rate

is now correspondingly weak and has done little to save us from facing the second weakest Rand on record and ever higher long-term interest rates.

The strength of the Rand is still much influenced by the state of the commodity-price cycle, as South Africa remains a commodity-based and exporting economy. It is also determined in large part by perceptions of South Africa’s economic future and the associated safety of investing in SA. Foreign and local investors require a return that compensates for the perceived risk of investing in SA- including the risk of rand weakness. These perceived risks influence flows of capital to and from SA and can strongly influence the foreign exchange value of the ZAR, as they have this year. As an emerging market, South African risk generally follows the average emerging market risk, but SA specific risk has recently risen dramatically in the face of income destroying load shedding and more recently for reputation destroying toenadering with the reviled Russians. This year the rand has weakened by about 13% vs the Aussie dollar and 11% Vs the EM basket. Much of the relative weakness occurred in January and February in response to load shedding. With additional exchange and bond market weakness (higher yield spreads) on the 10th May in response to the Russian revelations. (see figures 2,3 and 4)

The ratio of the USD/ZAR exchange rate to the USD/Emerging Market (EM) average provides a useful indicator of SA risk. This ratio indicates that SA is again in economic crisis territory. The hope is that this time is not different- and the USD/EM ratio recovers to something like normal, as it has done after all the other crises that have damaged the ZAR and the SA economy. Relative to an average EM currency the ZAR has never been weaker than it is now. The outlook for the SA economy, judged by this ratio, has never been as bleak as it is now.

In response to this exchange rate shock – for reasons specific to SA – the SA rate of inflation is very likely to trend higher, independently of by how much the Reserve Bank raises short-term interest rates to further reduce spending pressures on prices. Yet raising short-term rates is almost certainly negative for growth in incomes and employment of which the SA economy is already so sorely lacking, given load shedding and a general loss of confidence in the competence of the SA government. The forces that have given us this latest exchange rate shock are completely out of the Reserve Bank’s control. The

Governor needs to recognise this and do little additional harm to the economy and its growth prospects- by not reacting to the exchange rate shock.

It seems evident that the surging rand prices for our mineral exports may not help the Rand this time. A working Transnet to ship the metals and goods out the country would help – as even more important would be a consistent supply of electricity. But it is hard to be optimistic about such immediate responses and investors shared this pessimism earlier in the year and well before our damaging Russian connection came to light to add further to relative rand weakness.

Unfortunately, we do seem saddled for now with a weak Rand and a near-term uptick in inflation. Yet the weaker rand is not an unmitigated disaster. Exporters and firms competing with more expensive imports will benefit from higher rand prices for their production. Their extra rand costs of production will lag higher rand revenues until local inflation catches up with the inflation of the rand prices, they will be able to charge on foreign and domestic markets. The window of extra profitability will be supportive of extra output, incomes and employment. And of the rand values of the exporters and global plays (e.g. Richemont or Naspers) listed on the JSE. Sectors of the JSE that face abroad can provide a very good hedge against rand weakness that occurs for SA specific reasons, as they are predictably doing.

The rand cost of petrol and diesel will play an important role in influencing the inflation rate in the months to come. A saving grace for the inflation outlook is that the dollar price of oil and gas has fallen away- by more than the ZAR has weakened against the USD. (see figure 5)

The biggest danger to the local economy is that the Reserve Bank will raise interest rates further (the money market already expects increases of over 100b.p. in the next few months) The most recent attempt to support the ZAR raising interest rates by 50 b.p. at the last Monetary Policy has been a conspicuous failure. It has not helped, could not support the rand in the circumstances, but has further depressed spending and the growth outlook. And helped push long term interest rates and the cost of capital higher.

The best approach to rand shocks – that have nothing to do with monetary policy settings- is surely to ignore them – and let the inflation work itself out without higher interest rates. One has long hoped that SA had learned the lesson to not interfere with the currency market. Interest rates can have little impact on the ZAR in current circumstances. The best support for the rand will come from faster economic growth that raises incomes and tax revenues for the state.

Long term interest rates in SA are now punishingly higher than they were last week and the rand is now expected to weaken at an even more accelerated rate than was the case a week ago. This is because SA remains at greater risk – given the even more depressed outlook for growth – of not easily balancing its fiscal books. The expectation of even slower growth to follow still higher borrowing costs, as is widely expected, has added to these risks.

The only way out of the mess SA has got itself into is to surprise investors by delivering surprisingly faster growth- even an extra one percent higher GDP would be helpful. The Reserve Bank has a crucial role to play in this by ignoring the exchange rate shock. Eliminating load shedding and delivering more exports are even more important to improve the growth outlook and reduce SA risks.

A shock to the system- and getting over it

The latest shock to the SA currency and bond markets is of a large scale, similar to those of 2001, and of 2008-9, that was linked to the Global Financial Crisis, also to the Zuma-Nenegate shock of 2015-16, and the Covid shock of 2020. This shock is entirely of our own making. It is the punishing result of a failure to keep the lights on and choose our friends more carefully. We can assert this not only by reference to the abruptly higher rand costs of a USD or Euro, but by the poor performance of the ZAR against other emerging market (EM) and commodity currencies. A weakness that was pronounced earlier in the year as load shedding increasingly hurt the growth prospects of the economy and that was accentuated on the news of our arms business with Russia. The ZAR this year to the 24th of May, after a further burst of weakness on the 10th May, is about 10% weaker Vs the Aussie dollar and 12% weaker Vs the JPMorgan Index of EM exchange rates.

Fig.1 Relative performance in 2023 ; ZAR VS AUD and EM Index; Daily 2023 to 24th May 2023. (2023=100) Higher numbers indicate relative rand weakness.

The ZAR compared to a basket of seven EM currencies – the ZAR/EM ratio – has never been weaker than it is now. The ratio very easily identifies the periodic shocks to flows of capital to and from SA since 1995. One can only hope that this time will not be different and that the ZAR bounces back- at least relative to our peers.

The RSA bond market could not escape similar punishment. Yields on long dated RSA Rand and USD denominated debt rose by about 60 b.p. between the 9th and 15th of May having all tracked higher through much of 2023. The case for investing more in SA plant and equipment has become that much harder to make. And the rand -judged by the wider carry- the difference between interest rates in SA and the USA- is now expected to weaken at an even faster rate- despite recent rand weakness. All bad news for our economy

The weaker rand is not an unmitigated disaster. Exporters and firms competing with more expensive imports will benefit from higher rand prices. Their extra rand costs of production will lag higher rand revenues and until local inflation catches up with the higher rand prices they will be able to charge on

foreign and domestic markets. The window of extra profitability will be supportive of extra output, incomes and employment. And of the rand values of the exporters and global plays (e.g. Richemont or Naspers or the International Mining Houses) listed on the JSE and who account for more than half its market value. The JSE is not in shock- it is well hedged against SA specific shocks.

How quickly inflation rises in the months to come will depend on the rand price of imported oil. A saving grace for the inflation outlook is that the dollar price of oil has fallen by more than the rand- hence a lower rand price of a barrel of oil.

The interest rates set by the Reserve Bank will make no difference to the rand or the inflation rate. Hopefully they will react to an exchange rate shock by not reacting to one. And do what little they can not to slow down growth any further.

The Treasury could help –by keeping the peak loading generators on for longer. And pay for the extra diesel or LPG. Every hour of load shedding not only means less income and output generally – it means lower tax collections. Every rand spent on diesel by the public or on replacing Eskom means less tax revenue in proportion to the company and personal income tax rates and the conversion to solar

allowances. Spending taxpayers rands on diesel will pay for itself. And possibly produce the growth surprise that could turn, only can turn around the rand.

Parsing the increase in the Repo- and questioning its wisdom

There was no good reason for the Reserve Bank to have surprised with a 50 basis point increase in its repo rate. There is in fact no good reason at all to subject the beleaguered SA economy to any further increases in interest rates. Given the bank’s own assessment of the state of the economy. To quote the statement of the Monetary Policy Committee of the 30th March. “Turning to inflation prospects, our current growth forecasts leaves the output gap around zero, implying little positive or negative pressures on inflation from expected growth”. The output gap is the estimated difference between potential growth in the economy (the supply side) and the growth in demand expected. The expectations for both growth in demand and supply are depressingly slow- no more than 1% p.a. over the next two years.. But clearly there are no demand side pressures on the price level.

The Bank’s forecasting model indicates that every 1 per cent shock to the repo rate will reduce GDP growth by 0.17% on an annual basis with the peak impact two or three quarters after the interest rate shock. While inflation is predicted to decline by 0.12% two years after the shock. While these are the estimated impact of higher or lower interest rates, other things equal, other things are very likely to change in highly unpredictable ways. For example exchange rates, or food prices or electricity tariffs or export prices- supply side shocks – over which the Reserve Bank has no control, nor any superior ability to predict. And which are as likely to move higher or lower over the forecast period and therefore should be ignored when setting interest rates. The strong focus of policy attention should be on the demand side of the economy- on the potential output gap over which the Bank does exercise influence. And without excess demand price increases cannot continue in an ever-higher direction- irrespective of recent inflation. Why the Bank would risk even slower growth by imposing still higher short term interest rates is hard to appreciate.

Since its January meeting the Bank, by no means alone, has been surprised by global inflation, by food prices, by rand weakness etc, enough to have taken recent headline inflation rates above what was predicted at earlier meetings. Though the longer term expected trend in headline inflation remains as it was – pointing distinctly lower below the targeted band. Incidentally the core inflation rate that excludes energy and food prices – large supply side shocks – has behaved almost exactly as expected. All further reason to have stood pat.

There is perhaps more to the decision to raise interest rates than the usual focus on prices. The MPC statement and the Q&A session after the meeting cast unusual concern about the foreign financing needs of the SA economy. To quote the MPC statement again – “South Africa’s external financing needs are expected to rise. With a sharply lower export commodity price index, stable oil prices and somewhat weaker growth in export volumes, the current account balance is forecast to deteriorate to a deficit of 2.7% of GDP for the next three years. Weaker commodity prices and higher sate-owned enterprise financing needs will put pressure on financing conditions for rand-denominated bonds. Ten-year bond yields currently trade at about 11.2%, despite the expected moderation of inflation over the forecast period”

It therefore appears to me that higher interest rates to attract foreign capital interest rates may have played a decisive role in the MPC decision. The rand and the long end of the bond market did benefit from a wider interest rate spread in a modest way.  But such experiments in exchange rate management are surely not to be recommended, given all else that can happen to exchange rates.  I thought we have learned (expensively) to leave exchange rates and long-term interest rates to sort out balance of payments flows – and yet still to learn to set interest rates with the domestic economy front of mind.

SVB – the importance of understanding the drivers of market value

The demise of Silicone Valley Bank (SVB) the 15th largest US bank, with an important systemic role in the roll out of US Tech happened quickly. In less than 24 hours it was all over for shareholders as the regulators took over to prevent banking contagion. By offering insurance not only on the deposits of all denominations of SVB, but effectively on all deposits with US banks, should it be needed.

It was not a run on the banking system – depositors were not lining up to cash in their deposits- as they might have done in primitive times before. They were acting online, transferring their deposits as quickly as they could to their accounts with the banking behemoths JP Morgan, and their like.  As the venture capitalists and their many subsidiary companies did with their deposits with SVB,

It was clear what caused the panic withdrawal of deposits from SVB. It was a sudden loss in the share market value of SVB to which the depositors acted as they did. They may not have known what was going on but they took fright. It is the market value of a company and its capital raising potential that protects creditors and this protection had fallen away. For reasons that had everything to do with decisions taken by SVB itself on surely very poor advice, that investors in SVB had recognized as destroying the market value of SVB.

The problem for SVB and other banks was that the fixed interest rate yield on their essentially sound  assets had been  rising steadily, causing their values to decline, even as the interest rates paid on deposits were edging higher in response to Fed tightening. Accordingly, the net interest income earned by the banks and their earnings per share were in decline.  A trend clearly uncomfortable to earnings conscious and presumably earnings growth incentivized managers of SVB.  

The advice was to mark the portfolio to market values, and recognize the capital losses on the balance sheet. To raise additional share capital in the market to restore required capital to asset ratios and to invest the capital in higher yielding government and other securities. By so doing improving net interest income and the earnings outlook and the share price.

There was no regulatory compulsion to recognize the losses on their portfolio. The alternative was to have let the assets run off as they became due and to accept the consequent decline in earnings for the next three years or so and the possibly negative reactions of the capital market to a well understood and unavoidable economic reality. There would then have been no need to raise additional capital.

The capital market would surely have been capable of seeing beyond the decline in earnings and focused on the inherent quality of the SVB balance sheet and its potentially durable business model. The problem for SVB was that the capital market clearly did not think that the proposed plans for the balance sheet made good sense and that two billion dollars of extra capital required could be raised on reasonable terms.  Doubts that put pressure on the share price that undermined the possibility of raising the additional capital.

The protection in the form of market value for depositors and shareholders in SVB and beyond fell away dramatically and the bank went down. All because of a false belief in managing earnings per share and the failure to recognize how companies are properly appreciated and valued on the share market. Concerns that extend well beyond the short-term prospects for accounting earnings. Adjusting wisely to Covid 19 and its aftermaths has proved difficult enough for the great growth companies with the strong balance sheets. It is even more difficult for banks, with high degrees of leverage, to wisely adjust their balance sheets in such unpredictable circumstances. SVB clearly failed to do so.

The misery of national debt

Published Business Day March 10th 2023

Makawber’s principles apply to National as well as household budgets. Expenditure less than revenue equals happiness. Expenditure that consistently exceeds income brings misery. Iin the form of ever rising and more expensive levels of debt, the service of which takes an ever-larger share of the revenue collected and of all expenditure.  Paying interest and repaying capital maintains your credit rating -more or less-  it does not buy votes.

South Africa has been on this spendthrift path, without pause, ever since the Global Financial Crisis. Since fiscal year 2008-09 to date real government expenditure has grown by an average 3.2% p.a. Government revenues have lagged, growing by an average 2% p.a. after inflation. This extra 1.2% of spending makes a large difference to debt levels over time. Real GDP has grown by an immiserating 1.2% p.a. average since 2009.

Government debt net of cash was a manageable R483.2b in 2007/8 and equivalent to 20% of GDP. The net debt this past financial year is nearly ten times higher at R4483b and equivalent to over 67% of GDP. Servicing this debt took 8.8% of all government revenue in 2008-09. This share of revenue grew consistently to 18.8% in Covid year 2021 as revenues collapsed with the lockdowns. This depressing ratio fell back to 17.1% in 2021/22 as the inflationary comeback from Covid brought hundreds of billions of extra unexpected taxes from SA mining companies. A mixed blessing as these companies remained reluctant to invest more in SA and so paid more tax.

Not only did the volume of debt incurred rise, but interest rates both paid by the government and by private borrowers also rose well ahead of inflation to compensate investors in SA government and private debt for the dangerous trajectory of our debt. Such trends could easily be extrapolated into a debt crisis and be expected to do so. That if not corrected could lead to a desperate eventual resort to the central bank as a lender of last resort and its money printing press. That is to a default by inflating away the real value of the debts incurred. A not uncommon event in monetary history of the world.

The 2023-04 Budget has made an essential, praiseworthy attempt to reverse the direction of spending and revenue. Over the next three years all government spending is planned to grow by 8.5%, and more slowly than government revenue which is expected to increase by 10.4%. The extra borrowing, the fiscal deficit would then decline from the current 4.2% of GDP to 3.2% by 2025/06 despite very modest expected growth in GDP. If the plans materialize, the debt to GDP ratio will stabilize in the low 70% range and the debt service ratio will be contained below 20% of all revenues. A path to fiscal sustainability has been opened.

The issue of how well or badly the government spends the money collected or borrowed and then allocated across the spending departments and state sponsored enterprises, and how onerous is the tax regime, clearly influence economic growth. Fiscal responsibility of the kind, hopefully to be demonstrated, almost balancing the books, is vitally necessary for economic stability but is not sufficient to the purpose of faster economic growth. It is the larger task for government to get value for taxpayers income it extracts.

The economic dust seldom settles in South Africa. The Budget was soon overtaken by De Ruyter’s last stand. Yet judged by the muted reactions in the financial markets the Budget did little to change what we pay to raise capital, public and private. RSA 5 year bonds still yield well over 9% p.a. or a very expensive real 5% p.a. after expected inflation of 5.5% p.a. Judged by the difference between RSA and USA Bonds, the rand is still expected to weaken – by a punishing 5% p.a. over the next five years and about 7% a year on average over the next 10 years.  SA dollar denominated, 5 year debt, now yields 6.56% p.a. representing a default risk premium of 2.3% p.a. and more than double investors in Mexican debt pay for the same insurance. Clearly the market and the economy need much more convincing that we have permanently changed our ways.

Should auld acquaintance be forgot,
and auld lang syne?

Nostalgia has its comforts. But looking ahead rather than behind
may be the better New Year resolution. Especially for those with
the responsibility for directing a business enterprise. It is best for
them to move on from the inevitable mistakes they have made in
business or in life. To not throw good money after bad to avoid
embarrassment. Not to not sell off the best divisions to sustain the
underperformers with capital they should better be starved of.
Do as Woolworths did with David Jones – but do it much faster.
And change the seriously erring CEO and the Board members
who supported them sooner rather than later. Furthermore, do not
encumber the strong operating managers with the capital that was
once wasted overpaying for acquisitions. The poor deals and the
waste of shareholders capital were not their mistakes.
Yet they may be doing very well operating the plant and
equipment handed to them and need recognition and
encouragement accordingly. Therefore, the firm should
accurately estimate the current market value of the plant and
equipment they are held responsible for. And reward them when
they achieve returns on this capital that exceeds required returns,
the opportunity cost of the capital employed. The investors who
value the business will, as managers should, look forward and
estimate expected returns based on current market values – and
will add or subtract based on expected not past performance.
The future is for every business and every individual to prepare
for. The technology for dramatically improving the productivity of

capital is available for you and your competitors. If only you or
they knew better how to serve your key stakeholder, the
customer, they will attempt to do so expecting to add market
value for their owners. The future will be theirs that succeed.
Frustrated South African customers of the state-owned
enterprises know that they operate to serve other stakeholders,
not their customers. Other KPI’s are much more important. Most
obviously to serve the interest of their employees or suppliers
without regard for the bottom line. What will the future bring for
this operating model that so clearly fails to deliver to customers?
The obvious solution is to introduce incentives for them based on
the same return on capital criteria that makes private business so
customer friendly. Is this politically possible?
The pace of technology may well be accelerating and its
outcomes ever more uncertain. And a source of ever greater
anxiety to the bosses and their teams. Ours seems a less happy
era. Maybe technology is to blame. Yet there is also a business
imperative to apply technology, 1 to improve the resilience and
reduce the dissonance of the workforce, so enhancing
productivity and competitiveness.
The evidence from working from home, made possible by
improved technology, is very suggestive about what the future of
work may hold. It suggests that the future will be one of fewer
hours worked, including fewer (highly unproductive) hours getting
to and from the workplace. Fewer hours worked because
improved technology enables more output produced and
therefore more income per (fewer) hours worked required to
satisfy the necessities of life and more time to play or bring up the
children. If collaboration at the work-place is valuable – because it

makes the firm more innovative and competitive – the
representative firm may therefore have to pay more, as well as
give more time off, to get key workers to come to the office. And
for those who much prefer to work from home and are therefore
less productive, may well accept lower hourly rewards to do so.
The challenge for all will be to find meaning in life. A strong sense
of vocation, of finding purpose and satisfaction in work for its own
sake, as well as for what it may buy, including time-off will remain
as helpful as ever.

The elusive notion of risk

Risk is an elusive concept to pin down and for investors to grapple with in practical,
measurable terms.


Investors who take a position on the stock market understand clearly what it means when they’re told their investment has produced a particular return over a particular period.

Most will also tell you they understand the notion of investment risk as an uncertainty of outcome; in particular, the higher the risk one is exposed to, the higher the chance that one loses one’s money. However, it is also accepted that in order to obtain good returns, one needs to take on extra risk. Then, in hindsight, risk is often used to explain why the realised return on an investment is high, on the one hand, or sometimes disastrously low on the other.


Underlying these perceptions of risk is the fundamental market tenet that one must expect to get rewarded for taking a position on an uncertain future. Therefore, markets must “price” risk into a share price, so that the higher the perceived risk of that investment, the higher the required future return on the investment. The problem is that neither this market-determined required return nor the associated risk is objectively measurable.


Still, plenty of people have tried. Quantitative financial analysts and the pioneering work of Nobel prize-winning economist Harry Markowitz use a statistical measure known as standard deviation (of return) as a proxy for risk. Typically, researchers in financial analysis will calculate an estimate of this standard deviation by using past values of share price returns.


In other words, to calculate the risk of a quoted company they would first compute the daily (or weekly) return of the share price over a certain period, and then compute the standard deviation of those returns. This measure, often termed volatility, is then taken as a measure of company risk. We will discuss below the flaws in this approach to measuring risk, but first consider some examples of situations where risk is much more precisely measurable.


In the game of roulette, played in casinos and assuming, of course, an unbiased wheel, we have constant probabilities of the ball landing on any of 36 numbers and zero at each spin of the wheel. It will be easily accepted that the risk involved in a bet on, say, red is much less than the risk of betting on the number 8-black, and one is rewarded accordingly.


If a red number comes up and you’ve bet R1 on red, you get R2 back. If you bet R1 on black and it comes up, you get R36 back.


Because the probabilities are fixed at each spin of the wheel, you could precisely
calculate the expected return of your bet and the associated standard deviation of that return, which proxies for risk.

When one plays a game with fixed probabilities, one always knows precisely what one’s expected return is. But in financial markets, event probabilities are not known precisely and change over time.


The key point is that when one plays a game with fixed and known probabilities, and
places a particular bet in that game, one always knows precisely what one’s expected
return is, and also the risk one is exposed to.


But in financial markets, event probabilities are not known precisely and, in fact, change continuously over time. What’s more, there is no possible repetition within an economic system as there is in roulette; the clock cannot be put back, and no process can ever be repeated in exactly the same way.


However, in the case of measuring risk and return in financial markets, we can make some headway in certain circumstances.

For example, assuming the SA government does not default on its contractual payment obligation, one can calculate the exact realised return on an RSA government bond held to maturity.


This required return must reflect the chance of a country default (if there is a default, the return is zero). Apart from its local rand borrowing, the SA government also borrows money on foreign markets denominated in dollars. These SA “Yankee bonds” are traded in New York, along with similar dollar-denominated bonds from other countries.


The required premium of the return (the spread) over and above the return an investor obtains on US government bonds of similar tenure is termed the sovereign risk. It is a measure of the probability of the bonds being paid out, according to contract, in dollars.


One can then calculate the spreads for the different countries which have issued dollar bonds. So, in this case, one can quite precisely compare the market’s perceived risk of default for different countries in paying these dollar-denominated bonds, and compare sovereign risk across different countries.

In the share market, there is no similarly definitive way to obtain the expected return or the risk of any company share on the basis of share market prices. Market analysts often use proxies for comparative value (and hence comparative risk) such as p:es and various measures of yield, such as dividend yield or earnings yield. The underlying principle is that a high-risk company should be reflected in a comparatively low market price, given the current earnings or the dividend payout.

Quantitative portfolio analysts are, however, given the even more challenging task of
combining different shares and instruments into a portfolio of assets expected to yield some overall return for some, often pre-mandated, risk.


They are thus faced with the problem of estimating portfolio (or share) risk in order to construct portfolios that fall within their given risk mandate. Given this problem, analysts almost always opt for using the estimated standard deviation of historical share price returns as a measure of volatility, which are then used as a proxy for risk.


There are plenty of problems associated with using past market data to measure risk or return But there are plenty of problems associated with using past market data to measure risk or return; the underlying issue is that markets are assumed to be efficient. This means the share price at any time can be assumed to reflect known information about the underlying company, but that price will continuously change as new information flows into the market.

Given that this new information is, by definition, unexpected and hence not predictable in any way, the resulting movement in share prices is, in turn, unpredictable. Therefore, past returns can give no indication of what future returns might be.

Risk, in contrast, may have some momentum in that a dramatic event, such as 9/11, will generally give rise to an extended period of return volatility, as markets grapple to understand and price in the impact of the event on share values.

However, though we may be able to anticipate volatility in the short term, the ability to do so over time is confounded by the statistical requirement of parameter stationarity.

In other words, if one wants to estimate a parameter using observations of that parameter over time, the parameter one is measuring cannot itself change over that period.


It’s a bit like locating a target when it’s moving, but your locating method must assume that the target is stationary. In the case of share price (or portfolio) volatility, this is an untenable assumption.

The conclusion is that any attempt to measure risk is problematic, especially in the
context of listed companies.


However, there is little acknowledgment of this fact by analysts. Analysts require
estimates of risk as a key input into almost any comparative share valuation or portfolio recommendation, but carefully avoid any interrogation of the validity of their estimates of risk. Individual investors may believe they understand risk, but their perceptions are often governed by whatever return they receive.

So: risk is an elusive concept to pin down and for investors to grapple with in practical, measurable terms. Fortunately, investors can usually take comfort in the one clear truth offered up by financial analysis. This is that the only sensible investment strategy is to carefully diversify one’s portfolio across as many asset classes as possible.


Then, assuming the world continues to advance technologically in the same innovative and productive ways it has in the past, irrespective of what unexpected challenges may arise, one’s investment will yield attractive returns over a long period.

The dark side of the improved balance of payments

Brian Kantor

28th September 2022

The Covid lockdowns has quite dramatically altered the relationships between the South African economy and its global trading and financial partners. What followed Covid was a dramatic improvement in the balance of exports and imports. After 2020 exports, helped by higher prices, grew significantly faster than imports to take the balance of trade to a mammoth, nearly 10% of GDP by Q2 2021. As export prices have fallen off more recently the trade surplus has declined to a still impressive 4.8% of GDP in Q2 2022.

The difference between exports and imports is also the difference between GDP- output or equivalently incomes – earned producing that output – and Gross Domestic Expenditure –mostly on consumption by households and  partially on capital goods by firms – that can be funded with loans to supplement current incomes. The trade balance – when positive -represents an excess of local supply over local demands- a contributor to global supply chains- rather than a drawer or absorber of them.  The SA economy has thus helped dampen global inflation.

The closely watched current account of the balance of payments adds foreign mostly investment income to the trade balance. South African borrowers and capital raisers pay out interest and dividends at  higher rates and yields than they typically receive from their foreign investments. Even though South African’s foreign assets roughly match their foreign liabilities (thanks to Naspers and its Ten Cent investment) This force usually turns trade surpluses into current account deficits – being the sum of the trade balance and the net foreign income accounts.   

By definition of the balance of payments accounting system the current account deficits (or surpluses) are equal to foreign capital inflows or outflows. Instead of drawing on global capital markets to fund its capital expenditure budgets South African savers- almost all realized by its corporations to offset very marginal surpluses of the household sector and public sector deficits, became a significant source of savings for world capital markets. Instead of drawing on global capital markets to fund capital expenditure budgets we became a significant source of savings for world capital markets- some 300 billion rands worth since Covid. The current account is now in rough balance.

Rather a lender than a borrower is conventionally good news for balance sheets and credit ratings- – provided all else remains the same.  Ideally raising capital even debt – to spend on capital goods with long productive lives that earn above the cost of debt- is good for any company or government and all its dependents. It means faster growth- and faster growth is the key to attract capital – especially equity capital – on favourable risk adjusted terms. Though the influence of removing one of the SA deficits, the capital account deficit – and improving the fiscal deficit, also with the help of the exporters, has not been conspicuous in the market for rands. The exchange rate of the ZAR with the USD, as for all other currencies, is being dominated  by the dollar and the actions of the US Fed.

There is a dark side to South Africa’s lesser dependence on foreign capital. The reason the SA trade balance has improved as much as it has is because the rate at which South African’s have saved since Covid disrupted incomes and output has held up much better than the rate at which the economy has added to its capital stock. The ratio of Capital Expenditure to GDP has very worryingly continued to decline – from the 20% of GDP range before 2016 to the current 14% of GDP rate. The savings rate appears to have stabilized at the 14% rate.

These capital expenditure trends portend very poorly for the economy. They imply persistently slow growth that will continue to threaten the ability of the SA government to raise revenues to fund its ambitious welfare programmes. Slow growth adds to the risk of investing in SA and the cost of raising capital from all sources domestic and foreign. It means less capital expenditure and slower growth. Ideally South Africa should be raising its capital expenditure rate and funding more of it by attracting foreign capital on favourable terms, growing faster by reducing the risk premium with appropriate actions. Current account deficits and capital inflows to fund growth would then be very welcome.

How to improve the outlook for the rand

The rand has consistently declined by more than its purchasing power parity equivalent rate against leading currencies over the years. Strong action is needed to change this.

South Africans travelling abroad should not blame the rand for their lack of purchasing power, at least not lately. In mid-January 2016, a US dollar exchanged for R16.80, a British pound then cost R24. Observers of the gyrations of the foreign exchange value of the rand should know that its exchange rate has had very little to do with the differences in inflation between SA and its trading partners. The rand has consistently bought less abroad than it has at home.

The exchange value of the rand with the US dollar or sterling has been weaker than its purchasing power parity (PPP) equivalent rate of exchange ever since 1995, when SA’s capital market was opened up, though with varying degrees of weakness. Had the rand simply followed the ratio of the SA consumer price index (CPI) to the US CPI since 1995 a dollar would now cost a mere R8. Similarly, since 1995 the difference between SA and UK inflation has been an average of 3.3% a year while the pound on average has cost an average 8.2% extra a year in rands since 1995.

Yet not only has the rand depreciated by more than the differences in inflation over the past 27 years, it is also expected to carry on weakening by more than the expected differences in inflation. The rand is expected to lose its dollar value by an average rate of 7.6% a year over the next 10 years and at an average 6% rate a year over the next five years. This is known as the interest carry: the current differences between the market established rand yields on an RSA bond and the dollar yields on the US Treasury bonds of the same duration. While helpful to exporters and import replacers competing in the home and foreign markets (and to incoming tourists) this expectation of further consistent rand weakness has a damaging downside. It raises the cost of funding rand-denominated debt, increasing the required return on securities. Expected rand weakness sharply reduces the expected return from the RSA (government) 10-year bond to under 3% a year (10.4% nominal yield less 7.6%). This is less than the same return in US dollars offered by a US Treasury.

The expected rate of inflation can be accurately estimated or implied in the same bond markets. It can be measured as the difference between a vanilla government bond and an inflation-protected alternative of the same duration. The compensation to investors in the US accepting inflation risk is an extra 2.65% a year for a five-year bond and 5.91% a year extra for rand investors in RSA bonds. This difference in expected inflation of 3.2% a year is significantly less than the 6% rate at which the rand is expected to weaken against the dollar over the same five years. PPP does not only not hold, but it is not expected to hold in the future. Sadly therefore, even reducing expectations of inflation may not much improve the outlook for the rand – a major issue if the cost of raising foreign or domestic capital is to be reduced.

The full explanation for the exchange value of the rand is thus not to be found in the PPP rate but much more in the varying flows of capital into or out of emerging markets generally and to or away from the dollar. SA-specific risks move the ratio of the rand to other emerging market currencies about this long-term one-to-one ratio. Both the rand and the other emerging market currencies respond similarly to the same degrees of global risk tolerances that drives the US dollar stronger or weaker.

The task for SA lies in promoting capex (and so economic growth) by improving the outlook for the rand. It could do so by adopting policies that would make SA a superior emerging market attracting a much lower risk premium. SA’s recent impressive successes in the competitive businesses of international rugby and cricket, provide the case study to be emulated widely.

Reduce risk – improve growth – follow SA rugby

South Africans travelling abroad should not blame the rand for their lack of purchasing power- at least not lately. In mid-January 2016, a USD exchanged for 16.8 rands, the pound then cost R24. Observers of the gyrations of the foreign exchange value of the ZAR should know that the ZAR rate has had very little to do with differences in inflation between SA and its trading partners. The rand has consistently bought  less abroad than at home.

The exchange value of the ZAR with the US dollar or UK pound has been weaker than its purchasing power parity (PPP) equivalent rate of exchange ever since 1995 when the capital market was opened up. Though with varying degrees of weakness. Had the rand simply followed the ratio of the SA CPI to the US or UK CPI since 1995 a USD would now cost a mere R8. Since 1995 the difference between SA and UK inflation has been an average 3.3% p.a. while the pound on average has cost an average 8.2% p.a. extra in rands since 1995.

Yet it is not merely that the ZAR has depreciated by more than differences in inflation – it is expected to continue to weaken by more than the expected differences in inflation. The rand is expected to lose its dollar value by an average rate of 7.6% p.a. over the next 10 years and at an average 6% p.a. rate over the next five years. Known as the interest carry – these are the current differences between the market established rand yields on an RSA bond and the dollar yields on the US Treasury bonds of the same duration. While helpful to exporters and import replacers competing in the home and foreign markets – and to incoming tourists – this expectation of further consistent rand weakness has a damaging downside. It raises the cost of funding rand denominated debt, increasing the required return on securities that are expected to lose their dollar value at a rapid rate. Expected rand weakness sharply reduces the expected return from the RSA 10 year bond to under 3% p.a. (10.4 nominal yield less 7.6) Less than the same return in USD offered by a US Treasury.

The expected rate of inflation can be accurately estimated or implied in the same bond markets. It can be measured as the difference between a vanilla government bond and an inflation protected alternative of the same duration. The compensation to investors in the US accepting inflation risk is an extra 2.65% p.a. for a five-year bond and 5.91% p.a. extra for rand investors in RSA’s. This difference in inflation expected of 3.2% p.a. is significantly less than the 6% rate at which the USD/ZAR is expected to weaken over the same five years. PPP does not only not hold- it is not expected to hold in the future. Sadly therefore even reducing inflation expected may not much improve the outlook for the ZAR- essential if the cost of raising foreign or domestic capital is to be reduced.

The best companies to work for are those that perform best

Ask not what you can do for the boss. Ask what your boss can do for you

An earlier study of the returns from investing in the best companies (BCs) to work for, as revealed by their employees, has been replicated with very similar results – as reported in the recent Financial Analysts Journal. An index of US companies that best satisfy their employees, would have provided market beating returns over an extended period to 2020, on average a meaningful extra 2-3% p.a. over the long run. Incidentally a similar methodology applied to selected groups of companies with very good ESG qualifications revealed slightly inferior returns. It is understandable why investors might have paid up for companies to feel better about themselves. Less obvious is why investors have so conspicuously spurned the advantages of investing in companies that are so well appreciated by their employees.

A different relationship between the causes and effects of companies that best satisfy their employees may explain the observed outcomes. It is the economic and financial performance of the best companies surveyed that perhaps explains their superior status with employees more than the other way round. The better the economic performance of a company, the better the company will be able and willing to look after their managers and workers and win their trust.

The same many hours devoted with the same energy and skills to a struggling business, are very likely to provide very inferior rewards over a lifetime of work. Promotion and training opportunities will be more limited. Initiatives to encourage self-improvement of the workforce will be unaffordable and the job itself will be much less secure. Bonuses and share option schemes that come with success and that make climbing the slippery corporate ladders so attractive will be largely absent.

It turns out that the best companies to work for are also unusually successful when measured by the other criteria for performance. To quote the study, “Overall, the main takeaway from these statistics is that BCs are rarely tiny-cap stocks, they are typically large, and a few are extremely large companies…… , we also see that, on average, BCs have relatively high market-to-book ratios of 12.44 and gross-profit-to-total-assets ratios of 38%, and that BCs spend relatively little on capital expenditures (4% of revenue) and have relatively large amounts of intangibles in their balance sheet (22% of total assets)….. BCs are large companies, with an average (median) market capitalization of $55bn. This shows that BCs tend to be large companies and the size distribution is skewed to the right….”

Most large companies were small to begin with and size is a measure of their success- able to sustain better still to improve their returns on additional capital employed. Such achievements characterize the true growth companies well worth being an early investor or employee in. The ideal business to invest in or work for would be a start-up that grows rapidly and becomes large and consistently successful on all dimensions. Perhaps what the list of BC’s – that change significantly from year to year- about 20% enter and leave the lists annually – include a biased sample of surprisingly successful companies- revealed in part by their superior employment practice. The best run companies are priced for success and therefore returns realized may not beat the share market. The surprisingly improved companies will do so. Identifying surprising strength before other investors do is the holy grail of investors and indeed also of workers with choices to make.

The key success factor in any business are the capabilities of its senior managers and directors. The employed insiders are in a very good position to evaluate them. The transfer market can serve those with competitive and marketable skills as well as it does in football should they have reason to doubt their leaders. Moreover, as they do in football, they should not resent the high rewards received by the best executors, the true and rare superstars that create and preserve so much value for workers and shareholders and as important for their valued customers.
