“The net supply of Treasurys in 2009 and 2010 combined seems likely to total more than $3 trillion and could climb as high as $4 trillion. The Congressional Budget Office (CBO) estimates the 2009 Federal budget deficit to be $1.2 trillion. The consensus of private sector analysts is similar to that figure.”
