FDIC Historical Bank Data and Institutional Archives
The Federal Deposit Insurance Corporation maintains one of the most comprehensive longitudinal datasets on banking institutions in the United States, spanning failures, charters, mergers, and financial performance across decades. This page explains the scope of FDIC historical bank data and institutional archives, how the underlying systems are structured and accessed, the scenarios in which this data serves research and regulatory purposes, and the boundaries that define what the archives do and do not contain. For a broader orientation to the FDIC's functions and statutory mandate, the FDIC Authority resource index provides a navigational starting point across the full range of topics covered.
Definition and scope
FDIC historical bank data refers to the structured records the agency maintains on every institution that has ever held FDIC deposit insurance — from the inception of deposit insurance in 1934 through the present. The primary delivery mechanism for this data is the FDIC Statistics on Depository Institutions (SDI) tool and the underlying FDIC BankFind Suite, a publicly accessible application programming interface (API) that exposes machine-readable records on institutions, branches, financial summaries, and historical events.
The institutional scope covers more than 16,000 entities that have held FDIC certificates at some point since 1934, including active institutions, merged banks, voluntary liquidations, and failures. Each record is anchored to a unique FDIC certificate number — a permanent identifier that follows an institution through name changes, charter conversions, and supervisory transfers. This certificate number is the key linkage across datasets and distinguishes the FDIC's archive from other regulatory data sources such as the Federal Reserve's National Information Center, which tracks holding company structures separately.
The data dimensions fall into four categories:
- Institutional identifiers — legal name, charter class, regulatory agency, state and county of headquarters, FDIC certificate number, and date of insurance establishment.
- Financial performance data — call report-derived figures including total assets, total deposits, net income, return on assets, and capital ratios, reported at quarterly intervals.
- Branch-level data — physical locations, deposit totals by office, and branch opening or closing dates, sourced from the Summary of Deposits survey conducted annually each June.
- Event history — mergers, acquisitions, failures, assisted transactions, and charter changes, with effective dates and successor institution linkages.
How it works
The FDIC collects institutional financial data primarily through the Consolidated Reports of Condition and Income, commonly called Call Reports, which all FDIC-supervised and FDIC-insured institutions file with their primary federal regulator — the FDIC, the Office of the Comptroller of the Currency (OCC), or the Federal Reserve — on a quarterly basis. The Federal Financial Institutions Examination Council (FFIEC) coordinates Call Report standardization across agencies.
The BankFind Suite API serves as the technical access layer, with endpoints covering institutions (/institutions), financials (/financials), branches (/branches), failures (/failures), and summary (/summary) aggregations. Queries can be filtered by state, charter class, asset size, time period, and institution status. The API returns JSON-formatted data and supports bulk download for analytical workflows.
Contrast this with the FDIC Quarterly Banking Profile, which aggregates the same underlying Call Report data into pre-built industry summaries rather than institution-level records. The Quarterly Banking Profile answers macro-level questions — how the U.S. banking industry performed in a given quarter — while the historical bank data infrastructure answers institution-specific and longitudinal questions: what was a particular bank's capital ratio in 1989, or how many community banks with assets under $1 billion exited through merger between 2000 and 2010.
The FDIC Failed Bank List draws from the same archive, with the failures endpoint of BankFind Suite exposing records on every FDIC-insured institution that has failed since 1934 — including the acquiring institution, transaction type, and estimated cost to the Deposit Insurance Fund where that figure has been formally published by the FDIC.
Common scenarios
Academic and economic research. University researchers and Federal Reserve System economists routinely use SDI and BankFind data to construct panels studying credit cycles, bank consolidation, and community bank performance. The FDIC's Community Banking Research program has itself published studies using these archives to define and track community banks as a distinct institution class.
Due diligence and merger analysis. Acquiring institutions and their legal advisors use historical FDIC records to trace the regulatory and ownership history of a target bank, identifying prior enforcement actions, supervisory transfers, and charter changes that may affect transaction structuring. The certificate number provides continuity across corporate name changes.
Regulatory and supervisory benchmarking. Examiners and state banking departments reference peer group financial data — derived from the same Call Report pipeline — to benchmark an institution's performance ratios against similarly sized institutions in the same geographic region or charter class. This peer comparison framework is embedded in the CAMELS examination process, discussed in FDIC Bank Ratings: CAMELS.
Journalistic and public accountability use. Reporters covering regional banking stress, branch closures in underserved communities, or patterns in bank failures use BankFind Suite to build institution-level timelines. The public accessibility of the API without an access key for standard queries reflects the FDIC's statutory obligation under the Federal Deposit Insurance Act to maintain transparent public records.
Decision boundaries
FDIC historical bank data is authoritative for institutions that have held FDIC insurance. It does not cover credit unions, which are chartered and insured separately under the National Credit Union Administration (NCUA) — a distinction detailed in FDIC vs. NCUA. It also does not cover non-depository financial entities such as mortgage companies, securities broker-dealers, or insurance companies, regardless of their affiliation with FDIC-insured banks.
Financial data in the archive reflects Call Report submissions as filed, subject to amendments. Restated figures replace original submissions in the database when institutions file corrections, meaning the archive reflects the most current certified version rather than a static snapshot of original filings.
Branch-level deposit data from the Summary of Deposits survey captures deposits as of the last business day of each June — a single annual snapshot, not a continuous time series. This creates a meaningful analytical constraint: seasonal deposit fluctuations or mid-year branch openings and closings will not appear in branch-level historical records between annual survey dates.
The FDIC does not publish institution-level examination ratings (CAMELS scores) in BankFind or SDI. Those ratings are confidential supervisory information protected under 12 U.S.C. § 1820(d). The public-facing data therefore captures financial outcomes and structural events, not the supervisory assessments that inform regulatory intervention. Researchers requiring that distinction should cross-reference public FDIC Enforcement Actions records, which are published, against the financial data series.
