A rapid slowdown in the rate of U.S. inflation appears to have lost steam, potentially raising questions about how aggressively the Federal Reserve will cut interest rates early next year.

Federal Reserve Bank of Minneapolis President Neel Kashkari said he’ll be looking at incoming inflation data to determine whether another interest-rate cut is appropriate at the US central bank’s December meeting.

The Fed lowered rates by 25 basis points to a 20-month low, but economists say tariffs may throw a wrench in the rate cutting cycle.
