Waller's academic and policy research has centered on
monetary theory,
political economy and
macroeconomic theory. Shortly before and after joining the Federal Reserve Board of Governors, Waller was viewed as a
monetary policy "dove", favoring expansionary policy and low
interest rates. He worked closely with the St. Louis Federal Reserve bank's president,
James B. Bullard, who was a vocal supporter of lower interest rates in 2019. As inflation accelerated in 2021, though, Waller was an early advocate for tapering asset purchases, particularly purchases of
mortgage-backed securities, to create policy space to increase interest rates in 2022. In April 2022, he advocated aggressively raising the Federal Reserve's policy interest rate to contain inflation. The personal consumption expenditure measure of inflation, for which the Federal Reserve's target was 2% a year, was above 6% at the time. In July 2022, Waller and Federal Reserve Board staff member Andrew Figura issued a paper claiming that the U.S. economy could enjoy a "soft landing," with the unemployment rate rising only 1 percentage point or less as inflation declined from the levels of the time closer to the Federal Reserve's target level. A number of prominent economists contested that view, but as of 2024, it seemed that Figura and Waller were correct. As inflation came down in 2024, Waller supported reducing the Federal Reserve's policy rate. Waller has expressed skepticism about a
central bank digital currency (CBDC) in the United States, saying that it is not clear what market failure in the U.S. payments system it would resolve. The following year, during The Clearing House Annual Conference 2024, he likened
stablecoins to "synthetic" currency that could benefit the financial system by eliminating inefficiencies, but emphasized the need to address safety issues. On August 28th, 2025, morningstar.com reported Waller agreed with President Trump interest-rate cuts and that the aggressive tariffs inflationary impact will be temporary and can be "looked through" by the
Federal Reserve. Waller opposed the mandatory inclusion in 2023 of
climate risk management in financial institution planning, responding to the rescission of such standards in 2025 with the two-word statement, "Good riddance." == See also ==
