What Does the OCC Do? Chartering, Supervision, and Enforcement

The Office of the Comptroller of the Currency (OCC) charters, regulates, supervises, and enforces the rules for national banks, federal savings associations, and federal branches and agencies of foreign banks operating in the United States. Together those institutions hold roughly $16.7 trillion in assets, which makes the OCC one of the country’s most consequential financial regulators.1Office of the Comptroller of the Currency. Key Data and Statistics It is the oldest federal bank regulator, established during the Civil War era as a bureau of the U.S. Department of the Treasury, and it operates independently: the Treasury Secretary cannot delay its rules or intervene in its enforcement actions.2Office of the Law Revision Counsel. 12 USC 1

Which Banks the OCC Oversees

OCC jurisdiction covers three categories: national banks, federal savings associations (formerly called federal thrifts), and federal branches and agencies of foreign banks doing business in the United States.3eCFR. 12 CFR Part 4, Subpart A – Organization and Functions As of September 2024, the agency supervised about 751 national bank charters, 240 federal savings associations, and 49 federal branches and agencies.4U.S. Department of the Treasury. OCC FY 2026 Budget-in-Brief

You can usually tell whether a bank is OCC-regulated from its formal name. National banks are required to include the word “National” or the initials “N.A.” (short for National Association) in their title.5OCC. A Guide to Tribal Ownership of a National Bank Bank of America, N.A., Citibank, N.A., and Capital One, N.A. are all OCC-chartered.6OCC. Large and Global Financial Institution List If you’re not sure, the agency’s Financial Institution Search tool at occ.gov lets you look up any institution by name or charter number.7OCC. Financial Institution Search

Supervision is tiered by size. Institutions holding more than $500 billion in assets, and any bank with a foreign parent, fall under the OCC’s Large and Global Financial Institutions group, which keeps a continuous on-site examiner presence year-round.8OCC.

How the OCC Differs From the Fed and the FDIC

The United States has no single bank regulator. Which agency supervises a bank depends on how it is chartered. The OCC handles federally chartered banks. The Federal Reserve oversees state-chartered banks that are members of the Federal Reserve System, along with bank holding companies. The FDIC supervises state-chartered banks that are not Federal Reserve members.

The FDIC also plays a separate role that applies across the board: it insures deposits up to $250,000 per depositor per bank at virtually all banks, regardless of charter type. So a national bank is supervised by the OCC while your deposits at that bank are insured by the FDIC. Knowing which agency has authority matters when you file a complaint or want to know which rules apply to your accounts.

Chartering New Banks

One of the OCC’s defining functions is granting new federal bank charters. Under federal law, a group of at least five people can form a national banking association by filing articles of association with the Comptroller of the Currency.9Office of the Law Revision Counsel. 12 USC 21 – Formation of National Banking Associations After review, the Comptroller issues a certificate authorizing the bank to begin operations, but only if all legal requirements are met. The Comptroller can withhold that certificate if the bank appears to have been formed for illegitimate purposes.10Office of the Law Revision Counsel. 12 USC 27 – Certificate of Authority to Commence Banking

New bank applicants (called “de novo” banks) must meet demanding standards on capital, business planning, and management experience, all laid out in the Comptroller’s Licensing Manual and its four-stage process: prefiling discussions, formal filing, OCC review, and final decision.11OCC. Comptrollers Licensing Manual – Charters The OCC has also explored special purpose charters for fintech companies that do not take traditional deposits, though such applicants must still perform at least one core banking function (paying checks or lending money) and meet the same safety, soundness, and consumer protection standards as any other national bank.12OCC.

Ongoing Supervision and Examinations

Chartering a bank is only the beginning. The OCC monitors every institution it supervises through on-site examinations and off-site data analysis. Examiners review loan portfolios, internal audit reports, and risk management practices to catch problems early.

Each bank is scored using the CAMELS rating system, which covers six areas: capital adequacy, asset quality, management capability, earnings, liquidity, and sensitivity to market risk.13FDIC. Section 1.1 Basic Examination Concepts and Guidelines Each component gets its own rating, and the bank receives a composite score. Poor CAMELS ratings can trigger closer scrutiny, added reporting requirements, or formal enforcement. The OCC also runs a dedicated Cybersecurity Supervision Work Program aligned with the NIST Cybersecurity Framework.14OCC. Cybersecurity Supervision Work Program

Enforcement Powers

When a bank breaks the law or operates unsafely, the OCC has a range of tools that escalate with the severity of the problem.

The OCC can also impose civil money penalties on a daily basis, structured in three tiers by severity. Tier 1 covers any violation of a law, regulation, or written condition, with an inflation-adjusted maximum of $12,567 per day. Tier 2 covers reckless unsafe practices, breaches of fiduciary duty, or violations that form a pattern, cause more than minimal loss, or result in personal gain, with a maximum of $62,829 per day. Tier 3 covers knowing violations or unsafe practices that cause substantial losses to the bank or substantial gains to the wrongdoer, with a maximum of $2,513,215 per day.16Office of the Law Revision Counsel. 12 USC 1818 – Termination of Status as Insured Depository Institution The dollar figures shown reflect the 2025 inflation adjustment and change annually.17Federal Register. Notification of Inflation Adjustments for Civil Money Penalties Because they accrue daily, even a Tier 1 violation can add up to hundreds of thousands of dollars over weeks or months.

Consumer Protection

The OCC’s job is not just financial stability. The agency is also charged with ensuring fair access to financial services and fair treatment of customers.2Office of the Law Revision Counsel. 12 USC 1

Under the Community Reinvestment Act, the OCC evaluates whether national banks are meeting the credit needs of their entire communities, including low- and moderate-income neighborhoods, consistent with safe banking practices.18Federal Reserve Board. Community Reinvestment Act (CRA) CRA ratings are public, and a poor rating can affect a bank’s ability to open new branches or complete a merger. The OCC also monitors bank compliance with the Servicemembers Civil Relief Act, checking that banks are reducing interest rates to no more than 6 percent per year on obligations that predate active-duty military service and are not foreclosing on servicemember-owned property without a court order.19OCC. Comptrollers Handbook – Servicemembers Civil Relief Act For mortgages, the rate cap and foreclosure protections extend for one year after military service ends.

Filing a Complaint Against a National Bank

If you believe a national bank has mishandled your account, loan application, or another financial product, you can file a complaint through the OCC’s HelpWithMyBank.gov portal. The site answers common banking questions and lets you submit a formal complaint directly to the agency.20OCC. Consumer Complaints Confirm first that your bank is actually OCC-regulated using the Financial Institution Search tool. Complaints about state-chartered banks belong with the FDIC or your state banking department instead.

Preemption of State Law

One of the OCC’s most consequential powers involves federal preemption. Because national banks operate under federal charters, they sometimes follow federal rules even when state law would require something different. The Supreme Court has held that state law is preempted when it prevents or significantly interferes with a national bank’s exercise of its federal powers.21Federal Register. Preemption Determination – State Interest-on-Escrow Laws

Interest rates are the most familiar example. Under federal regulations, a national bank located in one state can charge interest at the highest rate that state allows for any licensed lender and then apply that rate to borrowers in other states, even those with lower caps.22eCFR. 12 CFR 7.4001 – Charging Interest by National Banks This “rate exportation” power is a major reason many large lenders choose a national bank charter. In 2024, the Supreme Court reaffirmed the framework in Cantero v. Bank of America, holding that courts must make a practical assessment of how much a particular state law actually interferes with federal banking powers before deciding whether it is preempted.21Federal Register. Preemption Determination – State Interest-on-Escrow Laws

How the OCC Is Funded

Unlike many federal agencies, the OCC receives no taxpayer appropriations from Congress. It is funded almost entirely through semiannual assessment fees paid by the institutions it supervises. Every national bank, federal savings association, and federal branch pays these fees twice a year, by March 31 and September 30, based on total assets.23eCFR. 12 CFR Part 8 – Assessment of Fees That funding model gives the agency financial independence, and it also ties the OCC’s budget to the size and number of institutions in the federal banking system.
