Wall Street slips as U.S. productivity falls, bond rout eases

Wall Street was pressured earlier in the day due to a selloff in the global bond market after the ECB said that investors should get used to volatility in the market. The selloff, however, eased by mid-morning with U.S. long-term Treasury debt yields falling from eight-month peaks. The IMF said the Fed should not raise rates until there are clear signs of a pickup in wages and inflation.
