Summary

Focus

The paper examines the relationship between monetary policy and market prices through the lens of central bank communication. Central bankers use forward guidance to steer market expectations of future monetary policy moves. At the same time, they rely on market prices to gauge the likely path of the economy and the appropriate stance of monetary policy. This two-way flow between market prices and forward guidance can create a circularity, and raises questions on how best to read market signals without distorting those same prices.

Contribution

The research is timely given the increasing importance of communication as a tool for central banks, especially since policy rates have been pushed down to their feasible lower limits. Policymakers are giving more speeches, holding more news conferences and embracing new communication channels on social media. They are also paying more attention to signals from financial markets. One example is market expectations of future inflation, also detailed in the speech "Can central banks talk too much?". This paper builds on previous theoretical contributions to construct a self-contained quantitative analysis of central bank communication and market prices. It raises important questions and provides insights on the effectiveness and design of forward guidance.

Findings

The analysis suggests that relying less on market signals increases the effectiveness of central bank communication. In their eagerness to correctly anticipate policy moves, market participants risk giving too much weight to central bankers' utterances and not enough to assessing economic data. If central bankers, in turn, trust markets to guide their actions, they may end up creating a feedback loop that cancels out the value of the very market signals they rely on. In this circular relationship, market outcomes reflect central bank actions, which in turn reflect market outcomes.
