Banks are regulated by multiple federal and state agencies, not just one
No single regulator oversees all banks in the United States. Instead, a bank's primary regulator depends on its charter type and size. A national bank (one with "National" in its name or "N.A." after it) answers to the Office of the Comptroller of the Currency, or OCC, which is part of the U.S. Treasury Department. A state-chartered bank that is a member of the Federal Reserve answers to both its state banking regulator and the Federal Reserve. A state-chartered bank that is not a Federal Reserve member answers to its state regulator and the Federal Deposit Insurance Corporation, or FDIC, if it carries FDIC insurance—which most do.
This split system exists because banks can choose to charter either at the federal or state level, and the regulators have divided responsibility accordingly. The result is that your bank probably has two or three regulators watching it at once, depending on what kind of charter it holds and whether it is large or small.
Key Takeaways
- The OCC regulates national banks, the Federal Reserve regulates state-chartered banks that are Fed members, and state banking departments regulate state-chartered banks.
- The FDIC insures deposits up to $250,000 per account holder per bank and also regulates state-chartered banks that are not Federal Reserve members.
- Large banks face additional oversight from the Federal Reserve's Board of Governors and may be subject to stress tests and capital requirements.
- You can find your bank's primary regulator by searching the FDIC's BankFind tool or calling your bank directly and asking.
- Regulators examine banks for safety and soundness, consumer protection, and compliance with lending and anti-money-laundering laws.
What the OCC does
The Office of the Comptroller of the Currency is a bureau of the U.S. Treasury and regulates all national banks. It issues charters to new national banks, examines them regularly for safety and soundness, and enforces federal banking laws. OCC examiners look at a bank's capital levels, loan quality, management practices, and risk management. They also make sure the bank is following consumer protection laws like the Truth in Lending Act and the Fair Housing Act.
If the OCC finds serious problems, it can issue a cease-and-desist order, impose fines, or in extreme cases, close the bank. The OCC also sets rules about what products national banks can offer and how they must disclose terms to customers. You can search for OCC-regulated banks and file a complaint with the OCC through its website.
What the Federal Reserve does
The Federal Reserve (the central bank of the United States) regulates state-chartered banks that are members of the Federal Reserve System. It also supervises bank holding companies and large financial institutions. The Fed conducts examinations similar to the OCC's, checking capital, asset quality, and risk management. For the largest banks, the Fed runs annual stress tests to see whether they could survive a severe economic downturn.
The Federal Reserve also sets monetary policy and manages the nation's payment systems, but its regulatory role focuses on safety and soundness. If you have a complaint about a Federal Reserve-regulated bank, you can file it with the Federal Reserve's consumer complaint center or contact the Federal Reserve Bank in your region.
What the FDIC does
The Federal Deposit Insurance Corporation insures deposits at member banks up to $250,000 per depositor per bank. This means if your bank fails, the FDIC will pay you back up to that limit. The FDIC also regulates state-chartered banks that are not members of the Federal Reserve System—these are called "state nonmember banks." FDIC examiners check these banks for safety and soundness just as OCC and Federal Reserve examiners do.
The FDIC maintains a fund paid for by bank premiums (not taxpayers) to cover deposit insurance claims. When a bank fails, the FDIC either arranges for another bank to take over its deposits and branches, or it pays depositors directly. You can check whether your bank is FDIC-insured and see your coverage limits using the FDIC's BankFind tool.
State banking regulators
Every state has a banking department or division (sometimes called the Department of Financial Regulation or similar) that charters and regulates state banks. State regulators examine banks for compliance with state law, which often mirrors federal requirements but can be stricter. A state-chartered bank must answer to its state regulator and also to either the Federal Reserve or the FDIC, depending on whether it is a Fed member.
State regulators also handle consumer complaints and can take enforcement action against banks that violate state law. If you have a complaint about a state-chartered bank, you can file it with your state's banking regulator. Most state banking departments have a consumer complaint process on their websites.
How to find your bank's regulator
The easiest way to find out who regulates your bank is to use the FDIC's BankFind tool at ibb.fdic.gov. Type in your bank's name and city, and the tool will show you the bank's charter type, its primary regulator, and whether it is FDIC-insured. You can also call your bank directly and ask which federal agency regulates it—the customer service line should be able to tell you.
If you need to file a complaint, knowing your bank's regulator matters because each one has its own complaint process. The FDIC, OCC, and Federal Reserve all accept consumer complaints online. State banking regulators also accept complaints through their websites or by mail.
What regulators actually examine
Bank regulators conduct on-site examinations at least once a year, and more often for large or troubled banks. During an exam, regulators look at the bank's capital (the cushion it has to absorb losses), the quality of its loans, whether it is following laws, and whether its management is competent. They also check that the bank is not taking on too much risk and that it has adequate systems to prevent fraud and money laundering.
Regulators also monitor banks between exams by reviewing financial reports and data. If a bank's condition changes significantly—for example, if loan losses spike or capital drops—regulators may conduct an unscheduled exam or increase their oversight. Large banks face continuous supervision and must meet strict capital and liquidity requirements set by the Federal Reserve.
What happens if a bank fails
If a bank becomes insolvent and cannot meet its obligations, its primary regulator will typically close it. The FDIC then takes over and either arranges for another bank to assume the failed bank's deposits and branches, or it pays depositors directly from the insurance fund. Deposits up to $250,000 per depositor per bank are covered. If you have more than $250,000 at one bank, the amount over that limit is at risk in a failure.
Bank failures are rare in the modern era because regulators catch problems early and require banks to maintain capital buffers. The last major wave of bank failures in the United States was in the 1980s and early 1990s. Since then, regulatory oversight has tightened significantly.
Frequently Asked Questions
Can I file a complaint if my bank is treating me unfairly?
Yes. You can file a complaint with your bank's primary regulator—the FDIC, OCC, or Federal Reserve—or with your state banking regulator. Most accept complaints online. You should also file a complaint with the bank itself first and give it time to respond. If the bank does not resolve the issue, then escalate to the regulator.
What does it mean if my bank is not FDIC-insured?
It means your deposits are not protected by federal insurance if the bank fails. Most banks are FDIC-insured, but some credit unions and other financial institutions are not. You can check using the FDIC's BankFind tool. If your bank is not insured, consider moving your money to an insured bank.
Do regulators prevent banks from charging high fees?
Regulators do not set fee caps, but they require banks to disclose fees clearly and fairly. They also enforce laws against unfair or deceptive practices. If you believe a fee is unfair or was not disclosed, you can file a complaint with your bank's regulator, though the regulator may not reverse the fee itself.
How often do regulators examine banks?
Most banks are examined at least once a year. Large banks and those with known problems are examined more frequently. Regulators also monitor banks continuously through financial reports and data. The exact frequency depends on the bank's size, risk profile, and regulatory history.
What is the difference between a national bank and a state bank?
A national bank is chartered by the federal government (OCC) and a state bank is chartered by a state. National banks must follow federal rules, while state banks follow state rules plus federal rules if they are Fed members or FDIC-insured. Both types are regulated, but the primary regulator differs.
