About this data

The FDIC Summary of Deposits is an annual survey of branch office deposits filed by every FDIC-insured institution as of June 30 each year. It is the authoritative source for local deposit market share and is the dataset regulators use when assessing competitive effects of bank mergers. Because it is annual, it reflects a point in time rather than current balances. Vault republishes it without modification, free to access and free to cite. Available to AI agents at vaultbot.ai/mcp.
