How FDIC deposit insurance works, and where its limits are
Deposit insurance is why a bank failure rarely costs ordinary savers money. Here is what the FDIC covers, how the $250,000 limit is counted, and what it does not protect.
When a bank fails, the headlines tend to focus on shareholders and executives. For most customers, the question that matters is simpler: is my money safe? In the United States the answer usually depends on federal deposit insurance, run by the Federal Deposit Insurance Corporation. Understanding how it works, and where it stops, helps explain why some bank failures barely register with the public while others cause panic.
Why deposit insurance exists
Banks take in deposits that customers can withdraw at any time and lend much of that money out for years. That mismatch is the business model itself, and it works as long as depositors do not all ask for their money back at once. When they do, even a solvent bank can be forced to sell assets at a loss and collapse. That is a bank run.
Runs were common in the early 1930s, when thousands of American banks failed. Congress created the FDIC through the Banking Act of 1933. The idea was that if ordinary depositors know their money is guaranteed, they have no reason to rush to the teller window at the first rumor, and the run never starts. Since the FDIC began insuring deposits in 1934, the agency says, no depositor has lost a penny of insured funds.
What is covered
FDIC insurance covers deposit products at insured banks: checking accounts, savings accounts, money market deposit accounts and certificates of deposit. Credit unions have a parallel system run by the National Credit Union Administration through the National Credit Union Share Insurance Fund.
It does not cover investment products, even if you bought them through a bank branch. Stocks, bonds, mutual funds, money market mutual funds, annuities, life insurance policies, crypto assets and the contents of a safe deposit box are not insured deposits. A money market mutual fund and a money market deposit account sound similar, but only the second one is a deposit.
How the $250,000 limit is counted
The standard maximum is $250,000 per depositor, per insured bank, for each account ownership category. Each part of that phrase matters.
Per depositor means the limit applies to a person, not to an account. Three savings accounts in your name alone at the same bank are added together and share one $250,000 limit.
Per insured bank means coverage at different banks is separate. Money spread across two unrelated banks is insured separately at each. Different branches of the same bank do not count as different banks, and some bank brands are trade names of a single chartered institution, so it is worth checking the FDIC's BankFind tool.
Per ownership category is the part most people overlook. The FDIC recognizes several categories, including single accounts, joint accounts, certain retirement accounts such as IRAs, trust accounts, and business accounts. Each category is insured separately. A person with a single account and a share of a joint account at the same bank can be insured for more than $250,000 in total because the two sit in different categories. In 2024 the FDIC simplified the rules for trust accounts, generally providing up to $250,000 per beneficiary, with a cap of five beneficiaries per owner at one bank.
What happens when a bank fails
Banks are closed by their chartering authority, a state banking regulator or the Office of the Comptroller of the Currency. The FDIC is then appointed receiver. In most cases it arranges for a healthy bank to take over the failed bank's deposits, often over a weekend, so on Monday customers simply find a new name on the door. When no buyer is found, the FDIC pays insured depositors directly, by check or by opening an account for them at another bank.
Uninsured depositors, those with balances above the limit, receive a receivership certificate for the excess. They may recover some or all of it as the FDIC sells the failed bank's assets, but recovery is not guaranteed and can take time.
Who pays for it
Deposit insurance is not funded by ordinary tax appropriations. Insured banks pay premiums, called assessments, into the Deposit Insurance Fund. The fund also earns interest on its investments in Treasury securities. The FDIC has authority to borrow from the Treasury if needed, and its insurance is backed by the full faith and credit of the United States government.
The 2023 failures and the limits of the limit
The failures of Silicon Valley Bank and Signature Bank in March 2023 showed what happens when a bank's deposits are mostly uninsured. Many of those banks' customers were businesses holding balances far above $250,000 to meet payroll and expenses. When concerns spread, those depositors had every reason to move their money quickly, and they did so with smartphone apps rather than in lines at a branch.
In that case regulators invoked the systemic risk exception in federal law, which allowed the FDIC to protect all depositors at those two banks, including uninsured ones. That was a specific decision for those failures, not a change to the standard limit. Losses to the Deposit Insurance Fund from the decision were covered by a special assessment on banks rather than by taxpayers.
The episode renewed debate about whether the limit should be higher for business payment accounts. The FDIC published a report in 2023 discussing options, including limited coverage, unlimited coverage and targeted coverage for business accounts. Any change to the general limit would require action by Congress.
Practical steps for savers
- Confirm your bank is FDIC insured. Insured banks display the FDIC sign, and you can search the agency's BankFind database.
- Add up your balances by ownership category at each bank, not by account.
- If you hold more than the limit in a single category, consider spreading money across separate banks or using different ownership categories that fit your situation.
- Remember that investment products bought at a bank are not deposits. They may be protected in other ways, such as SIPC coverage at brokerages, which protects against the failure of a brokerage firm but not against market losses.
- For fintech apps, check whether your money is held at an insured partner bank and how the app records your ownership. Insurance protects against the failure of the bank, not the failure of the app company.
The bottom line
Deposit insurance is one of the least visible but most effective pieces of the financial system. For the large majority of households, whose balances are well below the limit, a bank failure is an inconvenience rather than a loss. The protection has edges, though, and knowing where they are is the difference between assuming your money is safe and knowing it is.
