Federal Deposit Insurance Corp. Chairman Sheila Bair said the fund it uses to protect customer deposits at U.S. banks could dry up amid a surge in bank failures, as she responded to an industry outcry against new fees approved by the agency. Without these assessments, the deposit insurance fund could become insolvent this year," Bair wrote in a March 2 letter to the industry. "A large number" of bank failures may occur through 2010 because of "rapidly deteriorating economic conditions." The fund, which lost $33.5 billion in 2008, was drained by 25 bank failures last year. Sixteen banks have failed so far this year, further straining the fund. Smaller banks are outraged over the one-time fee ... Camden Fine, president of the Independent Community Bankers of America, said yesterday. The agency, which has released the change for 30 days of public comment, could modify the assessment to shift the burden to the large banks "that caused this train wreck," Fine said. "Community bankers are feeling like they are paying for the incompetence and greed of Wall Street," he said. Consumers should watch this issue closely, said Edmund Mierzwinski, consumer program director at U.S. PIRG, a Boston- based consumer-watchdog group. "I wouldn't take their money out of the bank yet," Mierzwinski said. "If the FDIC is saying that there is this serious problem, then we should all be concerned. I think there is a chance the FDIC is going to have to ask taxpayers for money in the future."
