WASHINGTON (AP) — Federal Reserve officials acknowledged at their most recent meeting in January that there had been “significant progress” in reducing U.S. inflation. But some of the policymakers expressed concern that strong growth in spending and hiring could disrupt that progress. In minutes from the Jan. 30-31 meeting released Wednesday, most Fed officials also said they were worried about moving too fast to cut their benchmark interest rate before it was clear that inflation was sustainably returning to their 2% target.
