As Fed Chairman Ben Bernanke indicated recently on 60 Minutes, today's FOMC statementindicates that the Federal Reserve feels that the U.S. economy has only tentatively achieved escape velocity, such that the Fed must continue to provide fuel to push the rocket ship further into orbit.

This is obvious in the fact that the Fed improved only slightly upon its assessment of the U.S. economy, as well as by the Fed's characterization of growth as "insufficient to bring down the unemployment rate." So little was changed in the policy statement that it gives the impression the Fed feels amply justified in maintaining its asset-purchase program. This was likely an intention of the statement.
