The Impact of Monetary Policy on the Exchange Rate: puzzling evidence from three emerging economies

Emanuel Kohlscheen

No 259, Working Papers Series from Central Bank of Brazil, Research Department

Abstract: This study investigates the impact effect of monetary policy shocks on the exchange rates of Brazil, Mexico and Chile. We find that even a focus on 1 day exchange rate changes following policy events – which reduces the potential for reverse causality considerably – fails to lend support for the conventional view that associates interest rate hikes with appreciations. This lack of empirical backing for the predictions of standard open economy models that, for instance, combine the UIP condition with rational expectations (as in Dornbusch (1976)) persists irrespective of whether we use the US Dollar or effective exchange rates, whether interest rate changes are anticipated or not, whether changes in the policy rate that were followed by exchange rate intervention are excluded or whether "contaminated" events are dropped from the analysis. We argue that it is difficult to attribute this stronger version of the exchange rate puzzle to fiscal dominance, as similar results are obtained in the case of Chile - a country that has had the highest possible short-term credit rating since 1997 and a debt/GDP ratio below 10%. Indeed, in Chile a 100 b.p. hike leads to a 2.2 to 2.6% devaluation of the Peso on impact.
