US Treasury Secretary Scott Besant said on Tuesday that he is confident that core inflation will continue in the United States despite the Iran war, and repeated his call for the Federal Reserve to cut its interest rates.

Besant said he could understand whether U.S. central bankers wanted to observe war-related economic developments before cutting rates, adding that it also made sense for U.S. President Donald Trump’s nominee as Fed chair, Kevin Warsh, to lead the next cycle of monetary adjustments.

If the Trump administration accepts current Fed Chair Jerome Powell to remain in the top job after his term ends in May, if Warsh’s nomination is not approved by the Senate by then, Besant said, “We want Kevin Warsh as soon as possible.”
