Warren Buffett has publicly endorsed Kevin Warsh as the new Federal Reserve chairman, calling the appointment a "good choice" for the central bank's leadership.

The Berkshire Hathaway chairman's comments, made in an interview with CNBC, offer a rare high-profile validation of Warsh's appointment shortly after he assumed the role.

Warsh made his mark during his first meeting as chair in June, where he held interest rates steady while outlining significant changes to the central bank's operational framework.

Buffett's support comes as markets continue to digest the implications of Warsh's leadership.

The selection of Warsh, nominated by President Donald Trump, has signaled a decisive break from previous market expectations for an immediate easing cycle.

Instead, the new chair has focused on structural adjustments to the Fed's balance sheet and reserve management.
