(Reuters) -The Federal Reserve will likely need to raise interest rates further to bring down inflation that is still too high, but the end to its current monetary policy tightening cycle is getting close, several U.S. central bank officials said on Monday. The Fed has raised interest rates by 5 percentage points since March 2022 to bring down the highest U.S. inflation in four decades. Fed policymakers opted last month to forego a rate increase to give themselves time to assess the still-developing effects of the previous hikes in borrowing costs, even as most also penciled in at least two more increases by the end of 2023.
