The Fed over the past year has assumed, backstopped, or committed to take on about $2 trillion in assets from shaky financial institutions including Bear Stearns, AIG, Citigroup and Bank of America. In some cases the banks will assume some of the losses, or Treasury will accept some of the losses before the Fed comes into the picture. Another $1 trillion in lending could occur in 2009 as liquidity programs are tapped further by borrowers and the Fed purchases more bonds such as the ones sold by Fannie and Freddie, and securites backed by student loans, auto loans, credit card receivables and small business loans. This would result in a balance sheet for the Fed over 3 times what it was 18 months ago in mid 2007.
