"The first thing Fed bashers should remember about the AIG bailout is the chaotic circumstances. The Fed barely knew how to spell AIG before the panic of September 2008; it didn't regulate insurance companies, and its leaders had no idea that a division of this particular insurance company had turned itself into a giant and overleveraged hedge fund, much less that AIG was entangled with other giant and overleveraged institutions through exotic financial gambles ultimately backed by sketchy mortgages. According to accounts of the crisis like David Wessel's In Fed We Trust and Andrew Ross Sorkin's Too Big to Fail, Geithner first discovered that AIG posed a potentially catastrophic risk to the global economy just as he and the rest of the Fed were frantically trying to persuade Bank of America to take over Merrill Lynch while searching for a buyer for Lehman Brothers in order to prevent the largest bankruptcy in the history of the planet.
