FDIC can only cover 1% of all deposits:
In the case of bank collapse, the FDIC has to step in to insure the value of deposits. Normally the FDIC attempts to maintain a fund at 1.25% of the value of its potential obligations. In recent months, however, this fund has slid to 1.19%, driven primarily by a rise in deposits, said Sheila Bair, chair of the FDIC. If this figure slides further to 1.15% it forces the FDIC to make moves to shore up the fund.
