Inflation pressures in South Africa are now likely becoming more generalized, reflecting demand-side pressure rather than only external factors, the central bank warned, seeming to signal an eventual monetary tightening."In general, monetary policy can do little to combat the impact or first round effects of inflation that is driven by exogenous shocks,” South African Reserve Bank Governor (SARB) Gill Marcus said in a statement on the bank’s website on Thursday."However, the most recent data seem to suggest that inflation is becoming more generalized, and may reflect the emergence of demand pressures. This is something that the Bank will monitor very carefully,” he said.
