The OCC is an independent U.S. Treasury bureau that charters, regulates, and supervises national banks, federal savings associations, and federal foreign-bank branches.
The Office of the Comptroller of the Currency (OCC) is an independent bureau of the U.S. Department of the Treasury. It charters, regulates, and supervises national banks, federal savings associations, and federal branches and agencies of foreign banks.
The OCC is a prudential bank regulator. It is not the deposit insurer, central bank, securities regulator, or primary regulator for every institution that uses the word bank.
| Institution type | OCC role |
|---|---|
| National Bank | Charters, regulates, and supervises |
| Federal savings association | Charters, regulates, and supervises |
| Federal branch or agency of a foreign bank | Licenses or supervises within its federal jurisdiction |
| State-chartered bank | Generally supervised through state authorities plus the Federal Reserve or FDIC, not the OCC as chartering authority |
| Credit union | Generally supervised or insured through the NCUA and applicable state authority |
Institution structures can be complex. A holding company, bank subsidiary, securities affiliate, and trust business may have different regulators.
The OCC evaluates applications for national-bank and federal-savings-association charters, branches, mergers, conversions, changes in control, and certain activities or structural changes.
Examiners assess financial condition, governance, risk management, operational resilience, compliance, and whether an institution operates safely and soundly.
The OCC issues regulations, bulletins, handbooks, interpretive letters, and other guidance relevant to institutions in its jurisdiction. A handbook is supervisory guidance, not a substitute for the statute, regulation, order, or signed agreement governing a specific issue.
The OCC can require corrective measures and take enforcement action for violations, unsafe or unsound practices, breaches of fiduciary duty, or failure to comply with written conditions and orders.
The OCC examines covered institutions for compliance with applicable consumer-banking laws and operates customer-assistance channels. A consumer should first identify the institution’s charter and regulator before submitting a complaint.
