The case for a U.S. interest rate cut remains unresolved as Federal Reserve officials head into their policy meeting later this month, with data showing fresh signs of higher inflation and President Donald Trump intensifying his demands for lower borrowing costs.

Christopher Waller, a potential contender to be the next chair of the central bank, said the Federal Reserve should not wait for the labor market to weaken to reduce interest rates.

“With inflation near target and the upside risks to inflation limited, we should not wait until the labor market deteriorates before we cut the policy rate,” he said. “I believe it makes sense to cut the (Fed’s) policy rate by 25 basis points two weeks from now.” (Twenty-five basis points equals one quarter of an interest rate point.)
