During the past few years much of my investment advice emphasised the importance of offshore investments. The normal reasons applied; diversification, policy uncertainty, political risks, and, of course, the exchange rate of the rand. We argued, correctly, that a number of factors were pointing to an imminent depreciation of the rand.
Issues such as slow growth, deteriorating fiscal accounts, likely downgrades, as well as political and social tensions and questionable political leadership, suggested that the rand could potentially depreciate significantly. In addition, international economic developments clearly favoured a stronger US dollar and lower commodity prices; all factors that are and were rand negative.
Our rand/dollar forecast a year ago was the most bearish of all economists’ (that I am aware off), yet even our negative view turned out to be far too optimistic; the rand’s collapse by year-end was nothing less than theatrical. And that’s where we are now. Many factors remain rand negative, with the only real difference from a year ago being that the rand is now significantly weaker. Can our currency go even lower?
I don’t know. What I do know is that investors often get sucked into the hysteria of a sliding asset only to regret their disinvestment decision when this asset rallies. It has happened in the past to the rand as well when many investors took their money “out” when the rand was at its weakest only to bring it “back” when the rand rebounded, making huge losses. Could this be another bear trap? Will the rand make a U-turn and surprise us all again? Maybe history can assist.
I have been doing exchange rate forecasts for decades and I have learned that I am not very good at it. My only consolation is that nobody seems to be very good at it either! But what I have noticed is that whenever the rand bombs out completely, like now, a sharp reversal usually follows. It is not easy to see these movements by looking at nominal exchange rates only, but a few tweaks here and there can make things a bit clearer.
Exchange rate theory is based on purchasing power. In simple terms, a weaker currency can export goods more competitively than a stronger currency. Eventually currencies’ exchange rates will converge on purchasing power. This theory has been popularised by The Economist’s Big Mac index where the over- or undervaluation of a currency is ‘’calculated’’ by comparing the prices of Big Mac burgers in the various countries.
I have done the same but instead of a burger index, I used a more representative basket and calculated the rand’s undervaluation to the US dollar expressed as a percentage, see graph: I have decided to use the lowest intraday nominal exchange rate of the rand as the final data point, roughly R18, reached on January 11.
Now, this note is not intended to defend a particular economic theory. What I wanted to achieve is to get a sense of the extent of the rand’s movement the past few months compared to historic changes.
Two factors are very important. The rand’s percentage undervaluation from this approach changes either if the nominal exchange rate itself changes, or if the percentage undervaluation changes because the rand becomes less (or more) undervalued due to the effect of inflation.
All this sounds very confusing. All I am saying is that the longer the rand remains “too” undervalued the more this value will become the “correct” value because inflation will eventually “catch-up”.
The following graph is similar to the previous one but also includes a percentage change in the nominal rand/dollar graph, as per the right hand axis:
The following graph again shows the percentage undervaluation of the rand but this time the inflation differential (difference between SA’s inflation and that of the US) is included:
A few observations:
So there we have it. The rand is at roughly R16 and very weak compared to the US dollar, but not as weak as during its all-time low. I am convinced the rand’s undervaluation will correct but I am unsure how it will correct. Will the exchange rate improve or will inflation eventually render the current nominal exchange rate “more” correct? My suspicion is that inflation will take most of the pressure.
I am also not sure if we have seen the end of this flick. The rand may continue its nominal fall over the next few months especially if we get a downgrade, enter a recession or if our weak political leadership remain at the helm.
So here’s my best advice as an economist:
All the above is economic gibberish simply because nobody knows what will happen tomorrow. It does appear as if the rand is unnaturally weak at R16.00 to the US dollar, but that is for today. Within a few months rising inflation may suggest that R16.00 is cheap. Furthermore, given the political blunders that we’ve been getting accustomed to R16.00 could also be cheap if certain macroeconomic policy-threats are actually implemented.
Personally, I think I will buy rands at R16.50 or cheaper and sell them at around R14.00. But, that is today; tomorrow I may feel different…
