Regulators will meet Sept. 29 to discuss how to rebuild the bank deposit insurance fund, which has been depleted by a sharp increase in bank failures, the Federal Deposit Insurance Corp. said in an agenda notice Wednesday.

The FDIC’s board is expected to propose and put out for public comment a number of options to replenish the fund, including tapping the agency’s $500 billion line of credit with Treasury, levying additional emergency fees on banks, encouraging banks to prepay their regular assessments, and possibly borrowing from healthier banks.

FDIC Chairman Sheila Bair has said all options are on the table and that the agency will seek feedback from the industry before making a final decision.

The board meeting next week will also provide an update of the agency’s expectations for the volume of bank failures that are still looming.

In May, the FDIC projected a loss of $70 billion for the insurance fund over the next five years, up from a prior forecast of $65 billion.

So far this year, 94 U.S. banks have failed, compared with 25 during all of last year and only three in 2007.

Those failures have whittled the balance of the insurance fund down to $10.4 billion at the end of the second quarter, from $45 billion a year earlier. The FDIC is careful to mention that it has an additional $32 billion in reserves to handle failures over the next year.
