Eric Rosengren, president of the Federal Reserve Bank of Boston, speaks about the state of the U.S. economy and the outlook for monetary policy. Rosengren said economic weakness in the first quarter shows the U.S. isn’t ready for an interest-rate increase. He called the March jobs report “disappointing” and said inflation remains “stubbornly below” the central bank’s 2 percent target. Rosengren speaks at an event hosted by Chatham House in London.
