Central Bank Communication and Monetary Policy: A Survey of Theory and Evidence

TLDR

Over the last two decades, communication has become an increasingly important aspect of monetary policy, and this development has spawned a huge new scholarly literature on central bank communication, mostly empirical and written in this decade. The authors survey the growing literature on central bank communication. They review empirical and theoretical studies. Evidence shows that communication can move markets, improve policy predictability, and aid macroeconomic goals, but variation across banks means no consensus on an optimal strategy yet.

Abstract

Over the last two decades, communication has become an increasingly important aspect of monetary policy. These real-world developments have spawned a huge new scholarly literature on central bank communication—mostly empirical, and almost all of it written in this decade. We survey this ever-growing literature. The evidence suggests that communication can be an important and powerful part of the central bank's toolkit since it has the ability to move financial markets, to enhance the predictability of monetary policy decisions, and potentially to help achieve central banks' macroeconomic objectives. However, the large variation in communication strategies across central banks suggests that a consensus has yet to emerge on what constitutes an optimal communication strategy.
