This, if combined with the modest stimulus the Obama Administration is proposing with its "fiscal cliff" deal, will significantly boost the economy:
"The Federal Reserve took a genuinely unexpected step Wednesday afternoon when it announced it would significantly enhance its current monetary easing program. The Fed, for the first time, committed to keeping monetary policy loose until the economy crosses precise thresholds — specifically, an unemployment rate below 6.5 percent or a inflation above 2.5 percent."
