A financial institution is not automatically a bank, even if it holds your money

The word "bank" has a legal meaning that is narrower than most people think. A bank is a financial institution licensed by federal or state regulators to accept deposits, make loans, and offer checking and savings accounts. Not every place that holds your money qualifies. Credit unions, savings and loan associations, money market funds, and brokerage firms all handle money, but they operate under different rules and offer different protections.

The distinction matters because it determines what happens if the institution fails, what insurance covers your deposits, and what consumer protections explore to your account. A bank failure and a credit union failure look similar from the outside but work differently on the inside.

Key Takeaways

  • Banks are licensed by the Office of the Comptroller of the Currency (federal) or state banking regulators, while credit unions are chartered by the National Credit Union Administration and savings and loans by the Office of Thrift Supervision.
  • Deposits in banks are insured up to $250,000 per account category by the Federal Deposit Insurance Corporation (FDIC), while credit union deposits are insured by the National Credit Union Share Insurance Fund (NCUSIF) under the same limit.
  • Brokerage firms, money market funds, and investment companies are not banks and do not offer FDIC or NCUSIF protection on the money you deposit with them.
  • The type of institution determines which federal agency oversees it, what consumer protections explore, and what happens to your money if the institution fails.

How banks are chartered and regulated

A bank must obtain a charter from either the federal government or a state government before it can operate. Federal charters come from the Office of the Comptroller of the Currency (OCC), which is part of the U.S. Department of the Treasury. State charters come from each state's banking regulator—usually called the Department of Banking or Division of Financial Institutions, though the name varies by state.

Once chartered, a bank must follow rules set by its primary regulator and often by secondary regulators as well. A nationally chartered bank answers to the OCC. A state-chartered bank that is insured by the FDIC answers to both its state regulator and the FDIC. These rules cover how much capital the bank must hold, what kinds of loans it can make, how it must handle customer information, and how it must report its financial condition.

The charter is not permanent. Regulators can revoke it if a bank violates rules or becomes insolvent. When that happens, the FDIC typically takes over and either arranges a sale to another bank or liquidates the institution.

Credit unions and savings and loans are not banks

A credit union is a member-owned cooperative that accepts deposits and makes loans, but it is chartered and regulated differently from a bank. Credit unions are chartered by the National Credit Union Administration (NCUA), a federal agency, or by state regulators. They serve a defined membership—often people who work for a particular employer, live in a particular area, or belong to a particular organization.

A savings and loan association (also called a thrift) is similar to a bank but was historically focused on mortgage lending. Savings and loans are chartered by the Office of Thrift Supervision (OTS), which is part of the OCC. Many savings and loans have converted to bank charters in recent decades, but some still operate under thrift charters.

Both credit unions and savings and loans offer deposit insurance, but not through the FDIC. Credit union deposits are insured by the National Credit Union Share Insurance Fund (NCUSIF) up to $250,000 per account category, the same limit as FDIC insurance. Savings and loan deposits are insured by the FDIC, just like bank deposits. The key difference is the regulator and the charter type, not the insurance level.

Brokerage firms and investment companies do not offer bank protections

A brokerage firm holds money and securities on your behalf, but it is not a bank. Brokerages are regulated by the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA), not by banking regulators. When you deposit money with a brokerage, that money is not insured by the FDIC or NCUSIF.

Instead, brokerage deposits are protected by SIPC insurance (Securities Investor Protection Corporation), which covers up to $500,000 per account if the brokerage fails—but only if the money is held in a brokerage account, not a cash management account. SIPC does not protect you against investment losses; it protects you only if the brokerage itself becomes insolvent and cannot return your money or securities.

Money market funds are mutual funds, not banks. They invest your money in short-term debt instruments and are regulated by the SEC. Your money in a money market fund is not insured by the FDIC, NCUSIF, or SIPC. If the fund loses value, you lose money.

What happens when a bank fails versus other institutions

When a bank fails, the FDIC steps in as the receiver. The FDIC pays out insured deposits up to $250,000 per account category from the Deposit Insurance Fund. If you have more than $250,000 in a single account at a failed bank, the amount over $250,000 becomes a claim against the bank's assets, and you may recover some or none of it depending on how much the bank's assets sell for.

When a credit union fails, the NCUA takes over and pays out insured shares the same way. When a brokerage fails, SIPC takes over and returns your securities or cash, up to the insurance limit. The process is similar, but the agency and the rules differ.

The timing also differs. FDIC payouts typically occur within days or weeks. NCUA payouts follow a similar timeline. SIPC claims can take longer because the agency must liquidate the brokerage's assets and determine what belongs to which customer.

How to tell what type of institution you are dealing with

The easiest way is to look at the institution's website or ask directly. Banks will say they are FDIC-insured. Credit unions will say they are NCUA-insured or state-insured. Brokerages will mention SIPC protection. If an institution does not mention insurance, it probably does not offer it.

You can also search the FDIC's BankFind tool online, which lists every FDIC-insured bank and branch. The NCUA maintains a similar search tool for credit unions. If an institution does not appear in either database, it is not a bank or credit union.

Some institutions blur the lines. A bank may own a brokerage subsidiary. A credit union may offer investment services through a partner. In those cases, the bank or credit union deposits are insured, but the investment accounts are not. Read the account agreement to see which insurance applies to each account you open.

Frequently Asked Questions

If I have money at a credit union, is it as safe as money at a bank?

Yes. Credit union deposits are insured by the NCUSIF up to $250,000 per account category, the same limit and the same protection as FDIC insurance. The regulator is different, but the insurance level and the process are equivalent. Both are backed by the federal government.

What if I have more than $250,000 at one bank?

The amount over $250,000 is not insured by the FDIC. If the bank fails, you become an unsecured creditor and may recover some or none of that amount depending on how much the bank's assets sell for. To protect money above $250,000, you can split it across multiple banks or use different account categories (such as a joint account or a retirement account) at the same bank, each of which has its own $250,000 insurance limit.

Is my money safe in a money market fund?

Money market funds are not insured by the FDIC, NCUSIF, or SIPC. Your money is invested in short-term debt, and the fund's value can go down. If you need may provide safety, use a bank or credit union savings account instead.

Can a bank call itself something other than "bank" and still be a bank?

Yes. Some banks use names like "Trust Company" or "Savings Bank" but are still chartered and regulated as banks. The charter type matters, not the name. Check the FDIC BankFind tool or ask the institution directly whether it is FDIC-insured.

What if a bank is both state-chartered and federally insured?

That is the most common setup. A state-chartered bank can choose to be insured by the FDIC. It then answers to both its state regulator and the FDIC. Both agencies have authority over the bank, and both sets of rules explore. Your deposits are still insured up to $250,000 per account category.
