Federal Reserve Chairman Ben S. Bernanke said the central bank may start dialing down its unprecedented bond-buying program this year and end it entirely in mid-2014 if the economy finally achieves the sustainable growth the Fed has sought since the recession ended in 2009.

The Federal Open Market Committee (FOMC) today left the monthly pace of bond purchases unchanged at $85 billion, while saying that “downside risks to the outlook for the economy and the labor market” have diminished. Policy makers raised their growth forecasts for next year to a range of 3 percent to 3.5 percent and reduced their outlook for unemployment to as low as 6.5 percent.

“If the incoming data are broadly consistent with this forecast, the committee currently anticipates that it would be appropriate to moderate the pace of purchases later this year,” Bernanke said in a press conference in Washington. If later reports meet the Fed's expectations, “we will continue to reduce the pace of purchases in measured steps through the first half of next year, ending purchases around mid-year.”
