The U.S. Federal Reserve and European Central Bank are expected to deliver sharply contrasting policy decisions next month, reflecting how the world’s two largest economies have moved from the Great Recession to the Great Divide. The U.S. and euro zone central banks have been on a similar path of monetary easing since the financial and economic crisis of 2007-09. The dollar and short-term U.S. bond yields have soared, while the euro and short-term euro zone bond yields have plunged.
