Yes, money market accounts held at banks or credit unions are FDIC insured (or NCUA insured at credit unions) up to $250,000 per depositor, per institution, per ownership category. That protection covers your principal and accrued interest if the bank fails, but it only applies to the deposit account version of this product, not to money market mutual funds sold by brokerages.
What Makes a Money Market Account Different From a Money Market Fund
The confusion around this topic almost always comes down to a naming collision. A money market account, sometimes called an MMA, is a deposit account offered by a bank or credit union. It works much like a savings account but typically pays a higher rate and may come with check writing or debit card access. Because it is a deposit product, it falls squarely under FDIC insurance rules.A money market fund, sometimes called a money market mutual fund, is an investment product sold through a brokerage firm. It holds a basket of short term, low risk securities such as Treasury bills, commercial paper, or municipal debt. Even though the name sounds nearly identical and the fund aims to keep a stable share price of one dollar, it is a security, not a deposit. Securities are not covered by the FDIC. Instead, most money market funds carry SIPC coverage through the brokerage, which protects against the failure of the brokerage firm itself, not against the fund losing value.
How FDIC Coverage Actually Works for a Money Market Account
When you open a money market account at an FDIC member bank, your deposit is automatically insured up to the standard limit without any extra enrollment or fee. The coverage applies per depositor, per insured bank, and per ownership category, which means the way you title your accounts can multiply your protection.- Single accounts: Insured up to $250,000 per owner at each bank.
- Joint accounts: Each co owner is insured up to $250,000, so a joint account can carry $500,000 in coverage.
- Retirement accounts (certain types): Insured separately, up to $250,000, apart from your other deposits at the same bank.
- Trust accounts: Coverage depends on the number of beneficiaries and can significantly exceed the standard limit.
If you hold a money market account and a regular savings account at the same bank under the same name, the FDIC adds them together and insures the combined total up to $250,000, not $250,000 for each account separately. Spreading large balances across different banks, or using different ownership categories, is the standard way savers extend coverage beyond that limit.
Comparing Coverage Across Common Cash Products
Because so many products share similar names and purposes, it helps to see the insurance status side by side before deciding where to park cash.| Product | Where it is sold | Insured by | Typical coverage limit |
|---|---|---|---|
| Bank money market account | Banks | FDIC | $250,000 per depositor, per bank, per category |
| Credit union money market account | Credit unions | NCUA | $250,000 per depositor, per credit union, per category |
| Money market mutual fund | Brokerages | SIPC (limited scope) | Covers brokerage failure, not investment loss |
| High yield savings account | Banks | FDIC | $250,000 per depositor, per bank, per category |
| Certificate of deposit | Banks | FDIC | $250,000 per depositor, per bank, per category |
Are Money Market Accounts FDIC Insured at Every Bank
Not automatically at every institution you might come across. Coverage only applies if the bank is an FDIC member, and nearly all banks operating in the United States are, but it is worth confirming before opening an account, especially with a newer online bank or a fintech company that partners with a bank behind the scenes. Many popular online savings and money market products are actually offered through a partner bank, and the marketing brand itself is not FDIC insured, the underlying bank is. Reading the account disclosures or checking the FDIC's own institution lookup tool clears this up quickly.Credit unions are not FDIC members because they operate under a parallel insurance system run by the National Credit Union Administration. NCUA coverage mirrors FDIC coverage almost exactly in structure and dollar limits, so a money market account at an insured credit union carries the same practical protection as one at an insured bank.
What Isn't Covered, Even Inside an Insured Account
FDIC insurance protects the deposit itself against bank failure. It does not protect against fraud, account fees eating into your balance, or a bank simply changing its rate. It also will not step in if you exceed the coverage limit at a single institution and that institution fails; only the amount up to the limit is guaranteed, and any excess becomes a claim against the failed bank's remaining assets, which may or may not be recovered.It is also worth remembering that FDIC insurance says nothing about the interest rate you earn. A money market account can be fully insured and still pay a mediocre rate. Insurance protects the safety of your principal, not the account's competitiveness, so comparing rates across insured institutions still matters when choosing where to keep your cash.
How to Confirm Your Own Account Is Protected
- Check for the FDIC sign or explicit mention of FDIC membership on the bank's website or account agreement.
- Use the FDIC's BankFind tool to search the institution by name and confirm active insured status.
- Add up all your deposits, across savings, checking, money market, and CDs, at that one bank to see if you are near the $250,000 combined limit.
- If you are close to or over the limit, consider splitting funds across ownership categories or additional FDIC insured banks.
- For any product with "money market" in the name, verify whether it is a bank deposit account or a brokerage fund before assuming FDIC coverage applies.
