", "\nABSTRACT\nConventional wisdom holds that lowering a home country's interest rate relative to another's will depreciate the domestic currency. We document that, at business‐cycle frequencies, U.S. forward guidance monetary policy easings had the opposite effect during the Great Recession. We attribute this effect to calendar‐based forward guidance that signaled economic weakness, resulting in a “flight‐to‐safety” effect and lower expected U.S. inflation. We also document cross‐currency heterogeneity: a surprise U.S. rate cut induced a larger appreciation of the dollar against currencies that typically depreciate more when the world economy is contracting. We build a model that can reconcile these findings."]
