WASHINGTON — Federal Reserve officials, convening in a wartime setting that began less than three weeks ago, are expected to hold interest rates steady on Wednesday even as a fresh jump in oil prices and data showing a rise in some aspects of inflation even before ​the start of the war with Iran may prompt them to recast the outlook for the U.S. economy, inflation and monetary policy. New projections to be released by the U.S. central bank at 2 p.m. EDT (1800 GMT) ‌will show how policymakers assess the economic impact of President Donald Trump’s decision to launch an open-ended conflict in the Middle East, but the environment remained volatile even as they began the second day of their latest two-day policy meeting. …US producer prices rose in February by 3.4% on a year-over-year basis. Rising producer prices can feed into retail ⁠costs and signal higher future inflation.
