Abstract: This paper shows that exchange rates respond to only the surprise component of
an actual US monetary policy change and that failure to disentangle the surprise component from
the actual monetary policy change can lead to an underestimation of the impact of monetary
policy, or even to a false acceptance of the hypothesis that monetary policy has no impact on
exchange rates. This finding implies that there is a need for reexamining the empirical analyses
of asset price responses to macro news that do not isolate the unexpected component of news
from the expected element. In addition, we add to the debate on how quickly exchange rates
respond to news by showing that the exchange rates under study absorb monetary policy
surprises within the same day as the news are announced.
Key words: Expectations, Monetary Policy, Federal Funds Futures, Exchange Rates.
