The science and practice of monetary policy communication: the ECB experience

Monetary policy communication influences economic decisions by shaping expectations among households, firms, and financial markets. The ECB notes that central bank statements guide financing conditions, credit availability, and investment choices by signaling future policy direction. Recent advances in data analysis and artificial intelligence now allow the ECB to assess communication tone more precisely, moving beyond simple word counts to contextual understanding.

ECB research demonstrates that its policy communication becomes more hawkish during tightening phases and more dovish during easing periods. Machine learning models confirm these shifts align closely with changes in the deposit facility rate. The ECB also finds that information from its policy statements improves forecasts of euro area core inflation several quarters ahead, even when accounting for staff projections.

Financial analysts reassess the ECB’s policy stance after Governing Council announcements, considering both decisions and accompanying communication. Unexpected revisions in their assessments can affect economic and financial conditions, even when rate changes are widely anticipated. Communication between meetings can influence market interest rates across maturities and help anticipate policy shifts, particularly before tightening episodes.

The ECB highlights challenges in communicating with households, who often interpret messages differently than financial markets. While markets respond to multiple dimensions of policy news—current rates, expected paths, and risk premia—households may not closely follow or fully grasp central bank communications. This underscores the need for clearer, more accessible messaging to ensure broader understanding.
