Christopher J Waller: Two thoughts on the transmission of monetary policy

Christopher J Waller, a member of the Board of Governors of the Federal Reserve System, delivered a speech at the ChaMP Conference on July 6, 2026, discussing two key aspects of monetary policy transmission. He emphasized the importance of initial conditions and the role of forward guidance in shaping policy outcomes.

Waller argued that understanding current conditions is crucial when determining the appropriate course of action for monetary policy. He cited the rapid inflation escalation in the United States post-pandemic as an example where traditional expectations failed to predict the actual outcomes. A significant shift in labor dynamics, with job vacancies surging, played a pivotal role in shaping the labor market's response to tightening monetary policy.

The speaker also highlighted the need to consider the magnitude and suddenness of economic and monetary policy shocks, noting that large shocks can lead to nonlinear responses due to behavioral changes. This concept, known as the Lucas critique, suggests that central bankers must account for these deviations when designing policy strategies.

Moving on to forward guidance, Waller acknowledged its potential benefits in strengthening policymaking and reducing uncertainty. However, he cautioned against overly rigid or strong guidance, as it can hinder policy transmission. He provided the example of the FOMC's forward guidance in September 2020, which, despite not changing the policy rate until March 2022, led to a significant rise in the two-year Treasury yield.

This early indicator reduced the typical lag in policy impact, demonstrating the power of forward guidance when employed judiciously.
