Many people became rightfully upset about bailouts given to big banks during the mortgage crisis. But it turns out that they are still going on, if more quietly, through the back door. The existence of one such secret deal, struck in July between the Federal Reserve Bank of New York and Bank of America, came to light just last week in court filings. Not only do the filings show the New York Fed helping to thwart another institution's fraud case against the bank, they also reveal that the New York Fed agreed to give away what may be billions of dollars in potential legal claims. The New York Fed said in a court filing that in July it had released Bank of America from all legal claims arising from losses in some mortgage-backed securities the Fed received when the government bailed out the American International Group in 2008. One surprise in the filing, which was part of a case brought by A.I.G., was that the New York Fed let Bank of America off the hook even as A.I.G. was seeking to recover $7 billion in losses on those very mortgage securities. What did the New York Fed get from Bank of America in this settlement? Some $43 million, it seems, from a small dispute the New York Fed had with the bank on two of the mortgage securities. At the same time, and for no compensation, it released Bank of America from all other legal claims. For zero compensation, the New York Fed released Bank of America from what may be sizable legal claims, knowing that A.I.G. was trying to recover on those claims.
