The Federal Reserve Bank of New York said ... that it had no choice but to instruct American International Group last November to reimburse the full amount of what it owed to big banks on derivatives contracts, a move that ended months of effort by the insurance giant to negotiate lower payments. The New York Fed, led at the time by then-President Timothy F. Geithner, directed AIG to make the payments after it received a massive government bailout. The officials said AIG lost its leverage in demanding a better deal once the company had been saved from bankruptcy. Lawmakers and financial analysts critical of the payouts say it amounted to a back-door bailout for big banks. AIG, the recipient of a $180 billion federal rescue package, ended up paying $14 billion to Goldman Sachs over months and $8.5 billion to Deutsche Bank, among others. Before the New York Fed intervened, AIG had been trying to persuade the firms to take discounts. [A Bloomberg] report concluded that the government needlessly overpaid $13 billion. The Federal Reserve has declined to detail the terms of the deals and specifics about negotiations with creditors. The Bloomberg report quoted an unnamed AIG executive who said he was pressured by New York Fed officials to refrain from filing any documents with the Securities and Exchange Commission that would divulge the deals' details.
