Abstract

The relationship between foreign exchange intervention and monetary policy underlies the question of whether sterilized interventions can affect the exchange rate. In this paper, I examine this relationship using data on U.S. foreign exchange interventions from 1985 to 1990, recently made publicly available. I examine whether interventions could be viewed as "signaling" changes in future monetary policy variables. I also consider whether changes in monetary policy may induce interventions in an effort to "lean against the wind" of exchange rate movements. Interestingly, I find evidence both that interventions help predict monetary policy variables, and that monetary variables help predict interventions. These relationships matter for understanding exchange rate behavior only if monetary variables indeed affect the exchange rate. Therefore, I also study the response of exchange rates to shocks in various monetary policy variables. The results provide new evidence on the relationship between exchange rates, monetary policy, and foreign exchange interventions.
