There are numerous factors influencing the currency at present, not least the attempts by many countries to weaken their currencies in order to export their way out of recession. With much of the developed world having opted for this path, their currencies, and notably the dollar, have seen value erosion.
Some emerging economies with strong currencies have also hopped onto the bandwagon: they are buying dollars at pace. South Africa, by contrast, has opted not to follow this trajectory. Buying dollars is an expensive route to take, given that the interest earned on dollars is extremely low, particularly relative to our own interest rates. Finance Minister Pravin Gordhan has made some concession, though, as part of this year's balance of payments surplus will be used to purchase additional reserves.
A further measure that some emerging markets have put in place is that of a Tobin tax - a tax on foreign capital inflows - in an attempt to discourage the inflows. South Africa is not really in a position to discourage inflows on the financial account of the balance of payments as we have to finance the current account deficit and, for now, Gordhan has poured cold water on this suggestion.
If all countries are simultaneously attempting to weaken their currency, it becomes a race to the bottom. Currency wars could lead to trade wars and in the end, no-one benefits.
It is even debatable as to whether South Africa should target a weaker rand. If we want to develop our infrastructure cheaply, we really want a strong rand to keep the cost of imported machinery and equipment down. Expanding our infrastructure is critical to ease the existing economic bottlenecks and create productive capacity for future growth.
The impact of insufficient power-generating ability is well known by most South Africans. We have a similar lack of capacity in water provision, transport networks, harbours and other infrastructure. It is essential to resolve these shortages in order to prepare the economy for future growth.
Long term currency movements tend to be driven by the underlying inflation rate differentials. Even though South Africa's inflation is in low territory and seemingly contained at present, we believe that this is unsustainable. Inflationary pressures are mounting from considerably higher labour costs, increased utility costs (notably electricity and water), and higher fuel costs (which filters through to most goods), as well as structural inefficiencies.
Transport accounts for 18.8% of the consumer price index. Transport inflation is currently a mere 1.1% and this is unsustainable, given the anticipated rising oil price combined with the galloping demand for oil emanating from China.
The rand is at the mercy of strong foreign flows and it is therefore difficult, if not impossible, to predict short term movements in the currency. It is however, reasonable to assume that, in the long term, the trend will be weak relative to our major trading currencies.
"I don't believe that anyone can consistently predict near term moves in the rand," concludes Pearse, "but there is a long-term desire on the part of most elements of the South African economy to weaken the rand."
