Intraday currency futures prices react to both surprises in the federal funds target rate (the target factor) and surprises in the anticipated future direction of Federal Reserve monetary policy (the path factor) in similar magnitude, and the reaction is short-lived. Dollar-denominated currency futures prices drop significantly in response to positive surprises (i.e., unexpected increases) in the target and path factors, but have generally little response to negative surprises. A monetary policy tightening during expansionary periods leads to an appreciation of the domestic currency, while a monetary policy loosening during recessionary periods tends to have no significant impact.
