Bernanke: More Fed bond buys “certainly possible”

The Federal Reserve could end up buying more than the $600 bln in U.S. government bonds it has committed to purchase if the economy fails to respond or unemployment stays too high, Fed Chairman Ben Bernanke said.
The Fed will regularly review the policy and could adjust the amount of buying up or down depending on the economy's path, he added.
In a rare televised interview, Bernanke told the CBS programme "60 Minutes" the Fed's actions are aimed at supporting what is still a fragile economic recovery, dismissing critics who argue the policy will lead to future inflation.
"What we're doing is lowering interest rates by buying Treasury securities," he said. "And by lowering interest rates, we hope to stimulate the economy to grow faster. The trick is to find the appropriate moment when to begin to unwind this policy. And that's what we're going to do."
Bernanke said it would take four to five years for the country's unemployment rate, which rose to 9.8% in November, to come down to what he called more "normal" levels of around 5-6%.
Asked if the central bank could go beyond the $600 bln of bond buys announced at its November meeting, Bernanke said: "Oh, it's certainly possible. It depends on the efficacy of the program. It depends, on inflation. And finally it depends on how the economy looks," he said.
But he also did not rule out stopping short of the total.
"We're gonna be regularly reviewing this," Bernanke said. "This is not something that we've set into automatic motion going forward. We want to continue to think about it. Whether it needs to be changed. Whether it needs to be increased or decreased or modified."
The U.S. economy grew at a modest 2.5% annual rate in the third quarter, and more vigorous growth is needed to bring down unemployment.
