U.S. President Donald Trump said on Friday he would not appoint anyone to head the Federal Reserve who would not lower interest rates from where they are, setting perhaps the most explicit litmus test yet for candidates to be the next central bank chief to align with his demands for steep rate cuts in order to get the job.

Donald Trump has said he will only pick a new Federal Reserve chair who will cut US interest rates, as he called on the central bank to slash borrowing costs to 1 per cent.

Federal Reserve Bank of Minneapolis President Neel Kashkari said he sees two interest-rate cuts as likely this year — with the first potentially in September — but warned that tariffs could have a delayed impact on inflation and policymakers should remain flexible.
