Agency to guarantee up to $1.4 trillion in banks' debt for more than 3 years, to add up to $500 billion to FDIC-backed deposits.WASHINGTON (AP) -- The FDIC will guarantee up to $1.4 trillion in U.S. bank s' debt for more than three years as part of the government's financial rescue plan.

The directors of the Federal Deposit Insurance Corp. voted Friday to approve the plan, which is meant to break the crippling logjam in

bank-to-bank lending.

The FDIC will provide temporary insurance for loans between banks - except for those for 30 days or less - guaranteeing the new debt in the event of payment default by the issuing bank.

The FDIC also will guarantee deposits in non-interest-bearing "transaction" accounts by removing the current $250,000 insurance limit on them through the end of next year. That could add as much as $500 billion to FDIC-backed deposits.
