St. Louis Federal Reserve President James Bullard is concerned about U.S. interest rates. Bullard warned of keeping rates too low for too long on Monday when he said "I do worry that keeping rates too low for too long could feed into future financial instability even if it doesn't look like we're in that situation today," Also, pressure on inflation could be caused by a tight U.S. labor market, making matters worse. Last week, the central bank's meeting minutes were released from April, showing expectations for a June rate hike. http://feeds.reuters.com/~r/reuters/topNews/~3/r-i33jLTVkM/us-usa-fed-bullard-idUSKCN0YE19B http://www.wochit.com This video was produced by YT Wochit Business using http://wochit.com
