Abstract

We study the response of South African monetary policy decisions to foreign monetary policy shocks. We estimate the extent of foreign monetary policy pass-through by augmenting standard Taylor rules and comparing the results within the context of a Global New-Keynesian Dynamic Stochastic General Equilibirum (DSGE) model. The general equilibrium model captures important spill-over effects that would otherwise have been ignored in a single equation setup. The results show that the relationship between foreign monetary policy shocks and South African interest rates is complicated - South Africa does not import foreign monetary policy directly, but is still affected. Except for the U.S. an increase in foreign interest rates lead to a decrease in South African interest rates - highlighting the complex channels that monetary policy authorities have to monitor outside of its economy.
