A high-yield money market account is a bank or credit union deposit that pays well above what the average money market account pays. That is the whole definition, and nobody enforces it: "high-yield" is a marketing label, not a regulated term, so the only way to know whether an account deserves it is to measure it against a baseline. The baseline is the FDIC's national deposit rate for money market accounts, which on the table effective 17 August 2026 was 0.63%, averaged across the $10,000 and $100,000 balance tiers. An account paying several times that is high-yield today. An account paying near it is not, whatever it is called, and nothing renames it when its rate drifts down.
This is the hub for the money market cluster. It prints the FDIC figure, dated, explains the number that sits beside it and must not be read as a rate, sets out how tiers and conditions turn one advertised rate into several, and ends with the five-minute check that works on any account. The linked pages take each part further, and the live comparison money market vs high-yield savings is the place to start if you are not yet sure which of the two you want.
"High-yield" is a claim, not a category
Regulation DD, the federal truth-in-savings rule, tells a bank how to state a rate: an advertisement that quotes one must express it as an annual percentage yield, using that term, and if the account has balance tiers the advertisement must state the APY for each tier along with the minimum balance for that tier. What the rule does not do is define "high-yield". No threshold triggers the label and none removes it. An account that led the market three years ago can still carry the name at a fraction of the competitive rate.
So the test is comparative. Take the FDIC's national deposit rate for the product, compare it with the APY the institution states for the balance you will actually hold, and ask whether the gap is worth the account's conditions. Finding the real top savings rate applies the same test to savings accounts and explains why no two comparison tables agree on the top rate; lists of the best money market account rates disagree for exactly the same reasons, and this page does not repeat them.
One distinction has to be settled before any of it matters. A money market account is a deposit — the FDIC lists money market deposit accounts among the products it insures. A money market fund is a mutual fund that the SEC regulates under Rule 2a-7, sold as a deposit alternative, insured by nobody, and capable of losing value. The words are nearly identical and the products are unrelated. Money market vs high-yield savings draws the line at summary level, and are money market accounts FDIC insured covers it in full. Everything on this page is about the account.
The FDIC number, and the one beside it you must not read
The Federal Deposit Insurance Corporation publishes national deposit rates by product on the third Monday of each month at fdic.gov/national-rates-and-rate-caps. The table current on 10 September 2026 is the one effective 17 August 2026; the next is due on 21 September.
| Product | FDIC national deposit rate, effective 17 August 2026 |
|---|---|
| Money market | 0.63% |
| Savings | 0.38% |
| Interest checking | 0.07% |
Three things about the money market figure.
It is an average of two balance tiers. The FDIC computes the savings and interest-checking rates on the $2,500 product tier, but "money market and certificate of deposit rates represent an average of the $10,000 and $100,000 product tiers". That is part of why the money market figure sits above the savings figure on the same table: it describes larger balances, at which more institutions pay something, not a better product.
It is deposit-weighted. The national rate is "the average of rates paid by all insured depository institutions and credit unions for which data is available, with rates weighted by each institution's share of domestic deposits". Because the average is weighted by share of domestic deposits, the institutions holding the largest balances pull it towards what they pay, and the rates online institutions advertise come from a smaller slice of the industry competing for deposits. Both numbers are real. Neither is wrong.
It lags. A table published on the third Monday reflects data collected before publication, and by the time you read it the market has moved. It is a floor to measure against, not a rate to chase.
On the same row, the FDIC prints a second figure: a national rate cap of 4.38%. That is the number that traps people. It is not a yield. It is a supervisory ceiling — for a non-maturity deposit such as a money market account, the FDIC defines it as "the higher of the national rate plus 75 basis points or the federal funds rate plus 75 basis points" (on the August table, 3.63 + 0.75 = 4.38; the column the FDIC heads "Treasury Yield" carries the effective federal funds rate for these rows, because, in the FDIC's footnote, "there is no comparable treasury yield") — that limits what a less-than-well-capitalised bank may offer under the FDIC's interest rate restrictions in 12 CFR 337.7. The 120-percent-of-Treasury leg applies only to certificates of deposit. It tells you what a struggling bank is not allowed to exceed. It tells you nothing about what any healthy bank is paying. How envelope budgeting works guards the same trap on its deposit-rate table, and this page repeats the warning because the cap sits one column from the average and is the larger, more attractive number. If you see that cap quoted anywhere as a money market account rate, the writer read the wrong column.
What the average means in dollars, on the FDIC's own figure: a $25,000 balance earning 0.63% earns $157.50 a year before tax. Each full percentage point above that — an illustrative spread, not a market rate — is worth:
| Balance | One percentage point, per year (illustrative) | After tax at a 22% marginal rate |
|---|---|---|
| $10,000 | $100 | $78 |
| $25,000 | $250 | $195 |
| $50,000 | $500 | $390 |
| $100,000 | $1,000 | $780 |
Interest is ordinary income, so the third column is closer to what you keep. On a modest balance the spread buys little and the account's conditions should decide the choice; on a six-figure balance the arithmetic starts to compete with instruments that are not money market accounts at all, which HYSA vs CD vs T-bills sets out.
Tiers: how one advertised rate becomes several
Regulation DD defines a tiered-rate account as "an account that has two or more interest rates that are applicable to specified balance levels". Money market accounts are commonly tiered, and the tier structure does more to your return than the headline. There are three shapes, and the disclosure must tell you which one you are looking at.
Whole-balance tiers. Cross the threshold and the tier's rate applies to the entire balance. Appendix A to Regulation DD calls this Method A: one APY per tier, applied to everything.
Split tiers. Each tier's rate applies only to the slice of the balance inside that tier — Method B. The disclosure then shows a range of APYs for each tier above the first, because the blended yield depends on how far into the tier you sit.
Capped tiers. The advertised rate applies up to a ceiling, and the balance above it earns a much lower rate. This is the structure behind most "up to" headlines.
An illustration, on rates chosen to be round and labelled as illustrative:
| Illustrative tier structure | Illustrative rate (%) |
|---|---|
| Under $10,000 | 1.00 |
| $10,000 to $49,999.99 | 2.00 |
| $50,000 and above | 3.00 |
On a $60,000 balance for a year, ignoring compounding:
- Whole-balance (Method A): $60,000 at 3.00% = $1,800.
- Split (Method B): $10,000 at 1.00% + $40,000 at 2.00% + $10,000 at 3.00% = $100 + $800 + $300 = $1,200, a blended 2.00%.
- Capped, if instead the 3.00% applied only to the first $25,000 and the rest earned 0.50%: $750 + $175 = $925, a blended 1.54%.
Same headline, three accounts, an $875 spread between best and worst. Regulation DD requires an advertisement that quotes an APY on a tiered account to state each tier's APY and the minimum balance that earns it, and the account-opening disclosure must state "any minimum balance required to … obtain the annual percentage yield disclosed". So the structure is always written down. It is rarely in the headline.
Two further rules protect you and are worth knowing by name. Interest must be calculated on "the full amount of principal in an account for each day", by the daily-balance or average-daily-balance method; the old low-balance and investable-balance methods are prohibited. And the institution must use the same method to decide whether you met a minimum balance as it uses to calculate the interest. If a disclosure describes anything else, read it twice.
Money market account rates is the page for the full rate-shopping mechanics — promotional rates, relationship pricing, why aggregators disagree — and how money market accounts work explains how the bank funds the rate in the first place.
Conditions: the rate is a behaviour
Beyond tiers, the advertised rate usually carries conditions. They are disclosed, they are rarely prominent, and each one converts a rate into a monthly task.
Introductory periods. A promotional rate reverts on a date. On a $20,000 balance, an illustrative four months at 4.00% followed by eight months at 1.00% is $266.67 + $133.33 = $400 for the year, a blended 2.00% — half the number in the advertisement. The reverted rate is the one you will hold for most of the time you hold the account.
Activity requirements. A direct deposit each month, a linked checking account, a minimum number of debit transactions, or a paid membership. Miss the requirement in a period and the rate steps down for that period, and nothing announces it. The brand pages in this cluster show how real products build these conditions: Zynlo and Quontic for online-bank boost mechanics, U.S. Bank and Wells Fargo for relationship and tier pricing at branch banks.
New-money rules. A promotional rate may apply only to funds not already at the institution. Moving money between your own accounts there may not qualify.
Fees and waivers. Money market accounts often carry a monthly maintenance fee, usually waived above a minimum balance. An illustrative $12 monthly fee is $144 a year — 2.88% of a $5,000 balance. On that balance, an illustrative 3.00% rate earns $150, leaving $6. On $25,000 the same fee leaves $606 of $750. The fee schedule, not the rate page, decides whether a small balance earns anything.
The rate is variable, and no notice is due. Regulation DD requires 30 days' advance notice of a change in terms that "may reduce the annual percentage yield or adversely affect the consumer" — and then exempts rate changes on variable-rate accounts from it. A bank may lower a variable rate tomorrow without telling you first. That is not a loophole; it is the definition of a variable-rate account, and it is why the verification habit matters more than the initial choice. If you want the rate fixed, the instrument is a certificate: CD vs money market account prices the lock and the penalty, banks with the best CD rates shows where the official CD baseline lives, and whether the lock pays is a bet nobody can call in advance.
What makes it a money market account at all
Under the Federal Reserve's Regulation D, a money market deposit account is a "savings deposit": the institution may at any time require seven days' written notice of a withdrawal — a right reserved in the contract — and the account is not payable on a fixed date. Until April 2020 the same definition limited "convenient" transfers — cheques, debit-card purchases, online and telephone transfers — to six a month. The Federal Reserve deleted that limit by interim final rule on 24 April 2020, and its own guidance is explicit that the rule "permits depository institutions to suspend enforcement of the six-transfer limit, but it does not require depository institutions to do so". Many institutions kept a limit, and the rule neither requires nor prohibits a fee for exceeding it. The transaction limit on your account is a contract term now, not a regulation, and it sits in the disclosure under "transaction limitations".
That history explains the product's shape. Money market accounts are commonly tiered, often carry a monthly fee waived above a minimum balance, and are the savings-type deposit most likely to come with cheques and a debit card. Money market account vs savings account weighs those features against the plain savings account most people already hold, and how money market accounts work covers accrual, compounding and crediting in detail.
Insurance, in one paragraph
A money market account at an FDIC-insured bank is insured to $250,000 per depositor, per insured bank, per ownership category, and the FDIC's own statement is that since 1933 "no depositor has lost a penny of FDIC-insured funds". A money market account at a federally insured credit union is insured to the same amount by a different agency, the National Credit Union Administration, through its share insurance fund — not by the FDIC, whatever a comparison table says. A money market fund is insured by neither; the FDIC lists mutual funds among the products it does not cover. Confirm the institution, not the brand: two brands on one charter share one limit, and the FDIC's BankFind tool settles which charter you are dealing with in a minute. Are money market accounts FDIC insured takes each of those sentences apart.
The brand pages, and why they print no rate
Four pages in this cluster exist because the search query is a bank's name. Each reads what that bank actually sells today — a money market account, a savings account by another name, or a money market fund through a brokerage arm — and compares its structure: charter, tiers, fees, conditions, access. None prints a rate and none recommends the product; that is the discipline of this page applied to a brand. They are Chase, Bank of America, U.S. Bank and Wells Fargo and Zynlo and Quontic.
Verifying any rate in five minutes
Do it at the institution's own site, not at a comparison table, and in this order:
- Find the APY, not the interest rate. Regulation DD requires the APY to be the stated figure; an interest rate may appear only alongside it and no more prominently. The two differ by compounding, as APR vs APY explains, and only the APY is comparable across accounts.
- Find the tier that matches the balance you will hold, and whether the structure is whole-balance, split or capped. The tier table is in the disclosure.
- Find every condition attached to the rate — direct deposit, linked account, activity, new money — and the date any introductory rate ends.
- Find the effective date on the rate page. A rate without a date is a rate you cannot verify.
- Find the fee schedule and the balance that waives the fee. Then do the fee arithmetic above on your own balance.
- Find the transaction limit and the fee for exceeding it.
- Find the insurance line and the charter. The disclosure should name the insured bank or credit union; for a bank, BankFind confirms it.
- Compare with the FDIC national deposit rate above, and decide whether the gap is worth the conditions.
Regulation DD requires the account disclosures to be given before the account is opened and on request at any time, so an institution that will not show you the tier table, the conditions and the fee schedule before you deposit has told you something.
What to actually do
Measure, do not trust the label. The FDIC figure at the top of this page is the baseline. An account near it is not high-yield; an account several times it is, today, and only today.
Read the tier table for your balance, not the headline. Whole-balance, split or capped — the same advertised rate produced an $875 spread on the illustrative $60,000 above.
Read the conditions as monthly tasks. Direct deposit, activity, linked account, new money. If you would not do the task every month, price the account at the rate you earn when you miss it.
Do the fee arithmetic on your balance. A maintenance fee on a small balance can take the whole return. The waiver threshold matters more than the rate below it.
Confirm it is an account, and whose. Deposit, not fund; the charter, not the brand; the FDIC for a bank, the NCUA for a credit union.
Diarise a check every six months. Variable rates fall without notice, and nothing renames a high-yield account when it stops being one. Put the date in the calendar next to the savings-rate check finding the real top savings rate recommends, and use the eight steps above each time.
