Bernanke sees signs of self-sustaining growth (by Greg Robb)

WASHINGTON (MarketWatch) -- Federal Reserve Board Chairman Ben Bernanke said Friday that he saw more signs that a self-sustaining recovery may be taking hold. In testimony prepared for delivery to the Senate Budget panel, Bernanke said he was still concerned about the slow improvement in the labor market and that there was still a risk of deflation. Bernanke defended the Fed's controversial $600 billion bond-buying program. He said the Fed had all the tools needed to reverse course when needed and said the central bank was "unwaveringly committed" to fighting inflation. He urged Congress to complete work on a credible plan to reduce the federal budget deficit.
