Bloomberg.com: News March 4 (Bloomberg) -- 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. U.S. community banks plan to flood the FDIC with about 5,000 letters in protest of the fees, according to a trade group. A large number of bank failures may occur through 2010 because of rapidly deteriorating economic conditions, Bair said in the letter. Without substantial amounts of additional assessment revenue in the near future, current projections indicate that the fund balance will approach zero or even become negative. The FDIC last week approved a one-time emergency fee and other assessment increases on the industry to rebuild a fund to repay customers for deposits of as much as $250,000 when a bank fails. The fees, opposed by the industry, may generate $27 billion this year after the fund fell to $18.9 billion in the fourth quarter from $34.6 billion in the previous period, the FDIC said. 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. Angry Bankers Smaller banks are outraged over the one-time fee, which could wipe out 50 percent to 100 percent of a banks 2009 earnings, Camden Fine, president of the Independent Community Bankers of America, said yesterday in a telephone interview. Ive never seen emotions like this, said Fine, adding that hes received more than 1,000 e-mails and telephone messages from angry bankers. The FDIC realizes that these assessments are a significant expense, particularly during a financial crisis and recession when bank earnings are under pressure, Bair wrote. We did not want to impose large assessments when the industry and economy are struggling. We searched for alternatives but found none better. 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. Legal Constraints Bair dismissed that suggestion. For risk-based assessments, our statute restricts us from discriminating against an institution because of size, Bair wrote. The deposit insurance fund wont dry up because the government can get funds from the industry and congressional appropriations, and borrow from the Treasury, Chip MacDonald, a partner specializing in financial services at law firm Jones Day, said today in a telephone interview. As a depositor, I am not worried in the least, MacDonald said. No one is going to let the FDIC go without any money. Consumers should watch this issue closely, said Edmund Mierzwinski, consumer program director at U.S. PIRG, a Boston- based consumer-watchdog group. I wouldnt 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. No Taxpayer Funds Bair rejected arguments that the agency should use government aid to rebuild the fund. The FDIC has authority to tap a $30 billion line of credit at the Treasury Department and legislation pending in Congress would boost the amount to $100 billion. Banks, not taxpayers, are expected to fund the system, Bair said. Asking for taxpayer support could paint all banks with the bailout brush. The FDIC will revise the interim rule, if appropriate, in light of the comments received, the agency said in a Federal Register notice.
