Euro Area Monetary Policy Shocks : Impact on Financial Asset Prices During the Crisis?

We use high-frequency intraday interest rate data to measure euro area monetary policy shocks on the days of ECB interest rate announcements between 2002 and 2013. In line with Gürkaynak et al. (2005), we look at monetary policy shocks along two time dimensions: one related to the current level of short-term interest rates and a second related to expectations for the future path of these rates. We undertake regression analysis in order to determine the impact of monetary policy shocks on euro-denominated financial asset prices and confirm that shocks related to the future path of monetary policy are an important driver, particularly for longer-term bond yields. We find that this relationship has changed for certain asset classes since the onset of the crisis, notably the sovereign bonds of stressed euro area countries. These findings highlight the changed nature of the monetary policy transmission mechanism for some euro area countries during the sovereign debt crisis
