High-Yield Savings
If an FDIC-insured bank fails, your covered deposits are protected up to at least $250,000 — automatically, with no application required. The Federal Deposit Insurance Corporation sets that standard limit as $250,000 per depositor, per insured bank, per ownership category. The last phrase matters: because coverage is calculated separately for each ownership category, the same person can be insured for more than $250,000 at a single bank when funds are held in different categories (for example, single accounts and joint accounts are insured separately).
Coverage applies to deposit products: checking accounts, savings accounts, money market deposit accounts, and certificates of deposit (CDs). It does not extend to investment products even when bought at a bank — stocks, bonds, mutual funds, annuities, life insurance policies, crypto assets, and the contents of a safe deposit box are not FDIC-insured.
To see exactly how the rules apply to your own accounts, the FDIC offers a free tool called EDIE, the Electronic Deposit Insurance Estimator, at edie.fdic.gov. It lets you enter your accounts and ownership categories to calculate your insured and any uninsured amounts.

High-Yield Savings
High-yield savings accounts, money market deposit accounts, and certificates of deposit are all bank deposit products — and when held at an FDIC-insured bank, each is insured up to at least $250,000 per depositor, per ownership category. The differences come down to access and rate structure, not safety. A high-yield savings account (a savings account marketed with a competitive rate) and a money market deposit account both let you withdraw funds on demand and typically pay a variable rate that can change at any time.
One naming trap is worth stressing: a money market DEPOSIT account (offered by a bank and FDIC-insured) is not the same thing as a money market FUND. The U.S. Securities and Exchange Commission notes that a money market fund is a type of mutual fund and has no FDIC insurance; as with any investment, you can lose money. If you are choosing among insured savings vehicles, confirm you are looking at a bank deposit account, not a fund.
Certificates of deposit trade liquidity for rate certainty. Investor.gov describes a CD as a savings account that holds a fixed amount for a fixed term, after which you receive your principal plus interest. In exchange for locking the money up, you generally accept an early-withdrawal penalty for taking funds out before maturity — the bank's disclosure statement should spell out that penalty before you commit.
The practical tradeoff: savings and money market deposit accounts keep your cash liquid but leave the rate free to move, while a CD fixes the rate for the term at the cost of easy access. This is educational information, not financial advice.
