Cleveland Federal Reserve President, the reason for the dissenting vote at the FOMC was concerns about inflation.

Cleveland Fed President Hammack cited his reason for casting a dissenting vote at the recent Federal Open Market Committee (FOMC) meeting, stating that he believes interest rates should be kept unchanged until further progress is made in inflation suppression.
At the regular meeting held on the 17th and 18th, the FOMC decided to lower the key policy interest rate by 0.25 points. This marks the third consecutive rate cut.

President Hammack explained his neutral stance on interest rates, stating that he believes they are close to a neutral level that neither stimulates nor restrains the economy. He suggested that interest rates should be maintained at a relatively high level to mildly restrain economic activity for the time being.

In the statement released on the 20th, the same president expressed his desire to keep the policy unchanged until new evidence indicating a recovery path to the 2% inflation target is obtained, based on the assumption that monetary policy is not far from a neutral stance.
Furthermore, he continued by stating, "If the inflation rate remains above 2% for a long time, there is a risk of inflation expectations becoming unstable, which would make it even more difficult to return the inflation rate to the target."
