Address by Governor
Mr. Stals discusses "The many facets of interest rates"
of the South African Reserve Bank, Dr. Chris Stals, at a Breakfast Meeting of the Insurance
Brokers Council of South Africa, on 2/9/98.
1. Introduction
Nobody will deny it that South Africa has extremely high interest rates at this
stage. In the context of South Africa's own historical record and measured against a current rate
of inflation of about 61⁄2 per cent, nominal interest rates are extremely high. In the context of the
world environment, and particularly within the group of emerging market economies, the level of
South African interest rates lies in the upper quartile, but is still beaten by a number of other
comparable countries. Six of the 24 emerging markets listed in the weekly publication of the
Economist, for example, have higher short-term interest rates than South Africa at this stage.
Nobody will deny it that the high level of interest rates is bad for the South
African economy, particularly at the current stage of the business cycle and a rather depressed
domestic economic situation. It is only the few savers we still have in the country, and the
old-aged people who live off their interest income, who may benefit from these high interest
rates. On the other hand, the high interest rates will most probably reduce consumption financed
with borrowed funds, and also investment in fixed capital, equipment and inventories. The future
production capacity of the economy is therefore constrained by the present adverse financial
conditions. In terms of domestic needs, South Africa now requires a stimulation of the economy,
and would prefer lower interest rates to encourage economic development.
There is also a fairly general consensus of opinion that the present high interest
rates were recently forced on South Africa by the international financial situation. The so-called
East Asian crisis that started to surface in Thailand more than a year ago spilled over into the
economies of many other countries. Even countries with more stable economies such as
Australia, New Zealand and Canada were adversely affected by these developments. Emerging
countries far away from the East Asian epicentre such as Mexico, Colombia, Brazil and
Venezuela have been infected by the problem. Countries with economies in transformation such
as the Czech Republic and Poland also suffered and the recent catastrophic developments in
Russia cannot be completely divorced from the East Asian crisis. In the end, South Africa also
could not escape from the turmoil.
There are major differences of opinion among economists inside and outside of
South Africa on what the reaction of the official macroeconomic policymakers in South Africa
should be to soften the blows for the economy. At the one extreme there is the International
Monetary Fund that believes that much more restrictive monetary and fiscal policies should have
been applied in South Africa in recent months to fend off the attacks of international speculators
and short-term profiteers.
At the other extreme we find economists in South Africa with major private sector
interests who believe that the Reserve Bank should have kept interest rates artificially low with a
complete disregard of the consequences this would have had for the exchange rate of the rand
and subsequent inflation. There are those who believe that the Reserve Bank should have done
more to keep the exchange rate stable, even if it should have required the reintroduction or
tightening of exchange controls.
There are many naive critics in South Africa who believe that the Reserve Bank is
fully responsible for the high interest rates and that the Reserve Bank indeed used its mythical
powers to force interest rates to these destructively high levels. In their ignorance they believe
that the Reserve Bank can even at this stage pull the rabbit from the hat and instantaneously
bring interest rates down again. Unfortunately, in the real world such miracles are just not
possible.
2. What caused interest rates to go up
To avoid confusion in this debate, the real causes for the recent sharp rise in
interest rates should be revisited. It will be recalled that in the first quarter of this year there was
wide-spread optimism that interest rates in South Africa could decline further during the course
of 1998. The Reserve Bank had already reduced its Bank rate from 17 to 16 per cent in October
1997, and to 15 per cent on 9 March 1998. Inflation was declining, foreign portfolio investments
flowed into the country, the foreign reserves were rising and the exchange rate of the rand was
under pressure to appreciate.
However, the situation changed dramatically in May 1998 when non-residents
reviewed their investment strategy and started to withdraw some of the funds they had previously
invested in South African bonds. During the four months January to April 1998, non-resident
investors increased their holdings of South African bonds by approximately R16 billion. Over
the next four months, that is from May to August 1998, they reduced their holdings of South
African bonds by about R19 billion.
This dramatic change of strategy had an almost immediate negative effect on the
overall demand and supply conditions in the South African financial markets. The yield on
long-term government bonds rose from just below 13 per cent at the beginning of May to a peak
of over 21 per cent last week. Other interest rates followed the upward trend and established the
extremely high levels we now have for the Reserve Bank's rate for repurchase transactions, the
prime overdraft rate, and the mortgage lending rate of banking institutions.
In this process, triggered by a decline of investors confidence in the emerging
markets of the world, little concern was shown for the depressed conditions in the South African
economy. No consideration was given to the needs, desires or expectations of the people of
South Africa. Neither the Minister of Finance nor the Governor of the Reserve Bank was
consulted by the markets before interest rates were forced to higher levels. The whole process
was driven by external factors that swept across many of the smaller economies of the world like
a huge tidal wave. The switch from a R16 billion inflow of capital for investment in South
African bonds in the first four months of 1998 to an outflow of an almost similar amount in the
next four months dramatically changed the demand versus supply conditions in the South
African financial markets. In the situation, it would have required a massive creation of money
by the Reserve Bank to prevent interest rates from rising to the extent they did. Such a creation of
money in turn would have added fuel to the inflationary pressures that were already stimulated by
the depreciation of the rand.
3. What can now be done to bring interest rates down?
It is amazing to read in the financial press in South Africa almost every day the
accusation that the high interest rates in South Africa at this stage are a reflection of the Reserve
Bank's deliberate "high-interest-rate-policy". The present level of interest rates is often described
as being "artificially" high because of Reserve Bank intervention in the market. These critics
overlook the fact that the Reserve Bank indeed raised the amount of accommodation made
available to banking institutions at the daily repurchase tender for central bank funds from
R4.1 billion early in May to R9.8 billion at this stage. This action by the Reserve Bank obviously
prevented interest rates from rising even further and, if anything, created an artificially low level
of interest rates in the country. Perhaps with some justification, this policy of the Bank was
recently criticised by the International Monetary Fund.
The Reserve Bank also made a huge amount of forward cover available to South
African residents with outstanding commitments in foreign currency, and to non-resident
investors with open rand positions in South Africa with the objective of discouraging them from
sending more funds out of the country. This policy undoubtedly contributed towards maintaining
interest rates at a lower level as the IMF quite correctly pointed out. In South Africa, the Bank is
widely criticised for having provided this forward cover, but at the same time also blamed for the
"high" interest rates.
After four months of heavy pummelling by the markets, South Africa now finds
itself in a situation where:
• the exchange rate of the rand has depreciated by about 25 per cent;
• the banking sector has lost a lot of liquidity;
• interest rates have risen to a level where borrowing from the banking sector for
the financing of additional economic activity has become almost prohibitive.
There is therefore an understandable pressure on the Reserve Bank to do
something that will bring interest rates down immediately and effectively for all borrowers in the
South African market. Can the Reserve bank do anything to salvage this situation?
A simplistic view is that the Bank should reduce the rate for its repurchase
transactions and therefore provide accommodation to banking institutions at a lower cost. This
view overlooks the fact that the repo rate of the Reserve Bank is determined on a daily basis
through a tender system, and is no longer fixed by the Bank. Should the Reserve Bank therefore
want to reduce the repo rate, it will have to offer more central bank funds ("high-powered"
money) to the banking institutions.
In deciding on its policy, the Reserve Bank must, however, take into account:
• the recent large outflows of funds through the Bond Exchange. An expansion of
domestic liquidity in this situation could facilitate the outflow of funds;
• existing relationships between interest rate margins, spot exchange rates and
forward rates. A disruption of these relationships can easily lead to new
speculative transactions against the rand;
• the continuing high rates of growth in bank credit extension and in the money
supply; and
• the need to keep inflation in check in the aftermath of a depreciation of the rand of
more than 20 per cent since May this year.
In this situation, it will be irresponsible for the Bank to create more money in an
effort to force interest rates down. Advantages, if any, to be gained from such a policy will be
very short-lived.
A solution in the short-term for the South African dilemma can only come from
the original source of the problem, that is, from the international financial markets. Confidence
must return to the many international fund managers who have decided in recent months to
withdraw substantial amounts of portfolio investments from the bond markets of the smaller
economies around the world. These fund withdrawals not only forced interest rates to higher
levels, but also created turmoil in the foreign exchange markets. A return of stability to these
markets will pave the way for lower interest rates in South Africa, and in many other affected
countries of the world. For any individual country such as South Africa to try to break out of
these shackles at this stage will be almost impossible, unless impenetrable brick walls will be
constructed around the South African economy to isolate it from the rest of the world.
4. Can South Africa survive with these high interest rates?
As already mentioned, the high level of interest rates at this stage is not consistent
with the current needs of the South African economy. There is, however, very little we can do to
get ourselves out of the dilemma in the very short-term.
The present unsatisfactory situation emphasises the long identified need for South
Africans to save a greater percentage of our income or, to put it in more sensible economic
language, to consume less. We must remember that, in terms of the macro-economy,
consumption financed with borrowed funds counts as negative saving. By borrowing from banks
to finance current expenditure, we actually use up tomorrow's income today.
The situation also emphasises once again that the South African total production
machinery must become more competitive. We must make ourselves not only more
self-sufficient in the provision of finance for our own economic development, but also in the
production of the goods and services we need for domestic consumption and real investment. In
other words, we must reduce our dependence on the rest of the world and eliminate our
vulnerability for recurrent balance of payments crises.
As long as these high interest rates are forced on us by the international situation
over which we have no control, a slow-down in total economic activity will be unavoidable.
Sensible adjustment to the realities of the situation will, however, avoid a major recession that is
already predicted in some quarters, and feared by many. To delay a spending decision today, does
not mean a permanent abolition of a justifiable need, but realistic deference to the economic
disciplines and constraints of an adverse global situation, until international conditions improve
again.
In the meantime, we should not lose confidence in the resilience of the South
African economy, and in its ability to weather the current storm. Looking around the world
today, we still have, even in the present adverse climate, many reasons for remaining optimistic
about the medium and longer-term prospects for the South African economy. Our banking
system remains sound, our financial markets operate with great efficiency, and a huge pent-up
demand for goods and services needs but little encouragement to re-stimulate the economy.
