We investigate the impact of the European Central Bank's monetary policy an- nouncements on the level and volatility of the EUR-US Dollar exchange rate em- ploying an AR-FIGARCH specification. Using high-frequency data we estimate the individual and complementary effects of the release of the interest rate decision, the ECB's introductory statement and the question and answer session. Surprise interest rate changes explain the movements in the exchange rate immediately after press release. During the introductory statement, communication with respect to future price developments is most relevant and has two important functions: (i) it explains the previously announced decision and (ii) it serves as a guide for the future path of monetary policy.European Central Bank, monetary policy announcements, communication, exchange rate, expectations, long memory GARCH processes
