Program instituted by the FDIC in the height of the worldwide banking crisis. Formed in 2008, TLGP was part of a coordinated response by the US government to the disruption in the financial system and the downfall of credit markets. The FDIC escalated its insurance coverage for depository accounts held at some financial institutions, and leant its guarantee to some unsecured credit obligations of those institutions, specifically in certificates of deposits and commercial paper.
