Politics and political economy
Exchange-rate volatility can complicate decisions concerning trade and investment and constrain a country’s economic growth. Understanding what contributes to a currency’s volatility is an important first step in assessing whether economic policy can reduce this volatility. For South Africa, changes in global commodity prices and financial-market risk perceptions drive most of the rand’s volatility. However, local political uncertainty also emerges as a significant source of volatility. More policy and political predictability could help to smooth the rand’s volatility.
