AIG in Hindsight, Journal of Economic Perspectives
The near-failure on September 16, 2008, of American International Group (AIG) was an iconic moment in the financial crisis. Large bets on real estate pushed AIG to the brink of bankruptcy. In one case, AIG used securities lending to transform insurance company assets into residential mortgage-backed securities (RMBS) and collateralized debt obligations (CDOs), ultimately losing at least $21 billion and threatening the solvency of the life insurance companies. AIG also sold insurance on multi-sector CDOs, backed by real estate assets, ultimately losing more than $30 billion. These activities were apparently motivated by a belief that AIG's real estate bets would not suffer defaults and were "money good". We find that these securities have in fact suffered write-downs and that the stark "money-good" claim can be rejected.
