FORECASTING RECESSION IN SOUTH AFRICA: A COMPARISON OF THE YIELD CURVE AND OTHER ECONOMIC INDICATORS

The paper uses the standard probit model proposed by Estrella and Mishkin (1996) , as well as the modified probit model suggested by Dueker (1997) , to examine the ability of the yield curve to predict recessions in South Africa, and compares its predictive power with other commonly used variables such as the growth rate of real money supply, changes in stock prices and the index of leading economic indicators. Compared with other indicators, real M3 growth does not provide much information about future recessions, whilst movements in the All‐Share index provide information for up to 12 months but do not do better than the yield curve. The index of leading economic indicators outperforms the yield spread in the short run up to 4 months but the yield spread performs better at longer horizons.     

INFLATION TARGETING AND THE FISHER EFFECT IN SOUTH AFRICA: AN EMPIRICAL INVESTIGATION

The paper analyses the relationship between expected inflation and nominal interest rates during a period of inflation targeting in South Africa, i.e. from 2000 to 2005. Specifically, it investigates the Fisher hypothesis that nominal interest rates move one‐to‐one with expected inflation, leaving the real interest rate unaffected. The analysis distinguishes between a short‐run Fisher effect and a long‐run Fisher effect. Using cointegration and error correction models (for monthly data for the period April 2000 to July 2005), it was found that the short‐run Fisher hypothesis did not hold during the relevant period under the inflation targeting monetary policy framework in South Africa. This is attributed to a combination of the South African Reserve Bank's (SARB) control over short‐term interest rates and the effects of the monetary transmission mechanism. The long‐run Fisher hypothesis could not be confirmed in its strictest form: while changes in inflation expectations move in the same direction as the nominal long‐term interest rate. This suggests that monetary policy has an influence on the real long‐term interest rate, which has positive implications for general economic activity, thus confirming the credibility of the inflation targeting framework.     

FINANCIAL AND MONETARY AUTONOMY AND INTERDEPENDENCE BETWEEN SOUTH AFRICA AND THE OTHER SACU COUNTRIES

The paper uses cointegration and error correction modelling techniques together with tests of weak exogeneity, and monthly interest rates for the period 1990 to 2005, to examine the degree of financial and monetary autonomy and interdependence between South Africa and the other Southern African Customs, Union (SACU) countries. The results reveal a high level of dependence of the other SACU countries' financial systems on South Africa's financial system, which suggests that a monetary unification with a single central bank (South African Reserve Bank) and monetary policy for the union is feasible.
