What Is Deposit Insurance Fund?

The Deposit Insurance Fund (DIF) is the pool of money the FDIC uses to pay insured depositors when a bank fails and to cover the costs of resolving failed institutions. It is funded entirely by premiums (assessments) paid by FDIC-insured banks — not by taxpayer money. The DIF is backed by the full faith and credit of the United States government.

Each insured bank pays quarterly assessments based on its deposit base and risk profile. Riskier banks pay higher premiums, creating an incentive for sound management. As of recent reporting, the DIF holds approximately $125-130 billion. The FDIC targets a reserve ratio (DIF balance divided by total insured deposits) of at least 1.35%, as mandated by the Dodd-Frank Act.

The fund was severely stressed during the 2008-2013 period, when over 500 banks failed and the DIF balance temporarily went negative. The FDIC responded by requiring banks to prepay three years of assessments and by implementing a special assessment on the largest institutions. The fund recovered to its target level by 2018. In 2023, the failures of Silicon Valley Bank and Signature Bank cost the DIF an estimated $22 billion, prompting another special assessment on large banks.

For depositors, the DIF's health is important context but not a cause for personal concern. Even if the fund were depleted, the FDIC has a $100 billion line of credit with the US Treasury, and Congress has historically authorized additional support when needed. Your insured deposits are guaranteed regardless of the DIF balance.
