The Labor Department statistics show unemployment dropped from 8.9% to 8.2%, however at the same time GDP growth for the 1st quarter only reached an estimated 2.1%, only slightly higher than the economy's potential of 2%, the figure for growth used by Fed chairman Bernanke. This has puzzled Bernanke because there was just not enough growth to account for the drop in the unemployment rate. A lower jobs number of 120,000 for jobs created in March 2012 gives the Fed chairman only a short time to respond with another version of the Operation Twist, before election season begins in earnest with the Fed wanting to stay neutral, says Lahart. Other reports suggest that the U.S. Federal Reserve having come under criticism for being too interventionist may decide to wait longer.
