WASHINGTON (Reuters) -The U.S. economy is on solid footing with inflation heading to the central bank's 2% target, but trade policies have clouded the outlook, Federal Reserve Governor Michael Barr said on Thursday. "The economy is on solid footing, with solid growth, low and stable unemployment, and inflation continuing to come down towards our 2% target," Barr said in remarks prepared for delivery to a small business symposium. But trade policy, including the announcement of massive tariffs that are now paused until the summer, "has led to an increase in uncertainty, contributing to declines in measures of business and consumer sentiment," Barr said.
