For months investors have been speculating about when and how the Fed will begin to extricate itself from its aggressive intervention in the economy. As early as March 15, the Federal Reserve reiterated its commitment to buy $600 billion of Treasury securities through June as part of its ongoing monetary stimulus. However, several Fed governors (albeit, all long-standing hawks) have since expressed their reservations about continuing QE2 and the ultra-low interest rate policy that were keys to the stabilization of the housing market and the economy at large.

On Wednesday, Kansas City Fed President Thomas Hoenigsaid that the Fed should "move the U.S. federal funds rate off of zero and toward 1% within a fairly short period of time." He also said he believes that aggressive Fed monetary policy was partly to blame for global commodity price inflation - a sentiment that has been refuted by Fed Chairman Bernanke. "Once again, there are signs that the world is building new economic imbalances and inflationary impulses," Hoenig said. On Tuesday, St. Louis Fed President James Bullardsaid that he believed the Treasury purchases should be cut by $100 billion. Last Friday, Philadelphia Fed President Charles Plosser said the Fed should start to unwind its stimulative monetary policy in the "not-too-distant future." Each of these Fed governors, voting members or not, carries influence over the process.
