Powell has said he will not resign voluntarily, and his term as Fed chairman will expire in May 2026.

Odaily News Powell once said that US law does not allow the president to remove him from office. Even if Trump requests him, he will not resign voluntarily and plans to serve his full term and continue to serve as chairman of the Federal Reserve until May 2026.
Powell's term as a member of the Fed's board of governors will last until January 2028. He also said this week that he believes the case currently before the U.S. Supreme Court is unlikely to apply to the Fed. [Reuters]
