Fed set for additional QE in 2013.

 Frustrated with the lack of substantial job gains, many Fed officials want the bank to continue buying long-term Treasurys even after Operation Twist expires. The purchases would be in addition to the $40B a month of mortgage-backed securities that the Fed's been scooping up. Under Twist, the bank's been paying for the long-term Treasurys with short-term paper, but as the latter is running out, the Fed will have to print money to keep the program going.
