The Temporary Liquidity Guarantee Program (TLGP) is a program adopted by the Federal Deposit Insurance Corporation (FDIC) on October 13, 2008 during the Global financial crisis of 2008 to encourage liquidity in the interbank lending market.

Several stated purposes of this program are (1) "to decrease the cost of bank funding so that bank lending to consumers and businesses will normalize." and (2) "to strengthen confidence and encourage liquidity in the banking system by guaranteeing newly issued senior unsecured debt of banks, thrifts, and certain holding company, and by providing full coverage of non-interest bearing deposit transaction accounts, regardless of dollar amount."

The TLG Program became effective on October 14, 2008 and was subsequently revised based on bank feedback.

Many FDIC insured entities have chosen to not participate ("opt out") in one or both of these programs.

The Interim Rule with request for comments was published on October 29, 2008, and provided for a 15 day comment period. The FDIC received more than 700 comments during the 15-day comment period. Later, the FDIC amended its Interim Rule. The Amended Interim Rule became effective on November 4, 2008, and was published in the Federal Register on November 7, 2008.
