Using Intraday Data to Gauge Financial Market Responses to Federal Reserve and ECB Monetary Policy Decisions
by Magnus Andersson
European Central Bank
This paper examines bond and stock market volatility reactions in the euro area and the United States following their respective economies’ monetary policy decisions, over a uniform sample period (April 1999–May 2006). For this purpose, intraday data on the U.S. and euro-area bond and stock markets are used. A strong upsurge in intraday volatility at the time of the release of the monetary policy decisions by the two central banks is found, which is more pronounced for the U.S. financial markets following Federal Reserve monetary policy decisions. Part of the increase in intraday volatility in the two economies surrounding monetary policy decisions can be explained by both news of the level of monetary policy and revisions in the expected future monetary policy path. The observed strong discrepancy between asset-price reactions in the United States and in the euro area following monetary policy decisions still remains a puzzle, although some tentative explanations are provided in the paper.
