Abstract

This paper studies drivers of high-frequency (daily) dynamics of the South African rand vis-à-vis the dollar from January 2001 to July 2007. We find strong nonlinear effects of commodity prices, perceived country and emerging market risk premium and changes in the dollareuro exchange rate on changes in daily returns of the rand-dollar exchange rate. We also identify a one-sided nonlinear mean reversion to the long-term monetary equilibrium. In addition we establish very short-lived effects on the exchange rate of selected macroeconomic surprises and central bank communication aimed at talking up the rand.
