We document how the impact of monetary surprises on euro-area and US financial markets has changed from 1999 to date. We use a definition of monetary policy surprises, which singles out movements in the long-end of the yield curve — rather than those changing nearby futures on the central bank reference rates. By focusing only on this component of monetary policy, our results are more comparable over time. We find a hump-shaped response of the yield curve to monetary policy surprises, both in the pre-crisis period and since 2013. During the crisis years, Fed path-surprises, largely through their effect on term premia, account for the impact on interest rates, which is found to be increasing in tenor. In the euro area, the path-surprises reflect the shifts in sovereign spreads, and have a large impact on the entire constellation of interest rates, exchange rates and equity markets.
