The Federal Reserve said Wednesday it is leaving its benchmark interest rate unchanged, resisting pressure from President Trump to lower U.S. borrowing costs as policy makers assess the economic impact of his trade policies. The Fed said it will maintain the federal funds rate at its current range of 4.25% to 4.5%, where it's been parked since the central bank last moved to lower short-term rates in December. The federal funds rate " the rate banks charge each other for short-term loans " helps determine what businesses and consumers pay in interest on loans and credit card debt. Wall Street interpreted Powell's comments as signaling an increased risk that the U.S. economy could slide into stagflation, or a combination of slower economic growth and higher inflation.
