Monetary Policy and Exchange Rate Dynamics: New Evidence from the Narrative Approach to Shock Identification

We argue that endogenous and anticipated movements in interest rates lead to underestimates of the speed and magnitude of the exchange rate response to monetary policy. Employing the Romer and Romer (2004) exogenous monetary policy shock measure, we find that the effect of a one percentage point increase in the U.S. interest rate is up to twice as large and 3 times as fast as that obtained using the actual federal funds rate to identify monetary shocks. Moreover, new evidence from open economy VARs emphasises the adjustment role of the exchange rate. U.S. prices and output respond almost twice as quickly as they do in a closed economy VAR using the Romer and Romber shock measure. There is also evidence of stronger international transmission of U.S. monetary shocks. Overall, the estimated response speeds and magnitudes are more easily reconciled with existing models than previous empirical work.
