Money market accounts pay interest rates that change weekly, and the rate you get depends on your bank, how much you deposit, and the current Federal Reserve rate
The interest rate on a money market account is not fixed. It moves up and down based on what the Federal Reserve does with its benchmark rate, which it adjusts roughly eight times a year. When the Fed raises rates, banks typically raise the rates they pay on savings products within days or weeks. When the Fed cuts rates, banks do the same.
Right now, money market accounts at different banks pay different rates even though they all respond to the same Fed rate. A bank offering 4.50% annual percentage yield (APY) and a bank offering 3.75% APY are both legal and both real—the difference comes down to how much competition that bank faces for deposits and how much it wants to grow. Online banks tend to pay higher rates than brick-and-mortar banks because they have lower overhead costs.
The rate you personally receive also depends on your balance. Some banks pay one rate on balances up to $25,000 and a higher rate on anything above that. Others pay the same rate regardless of balance. You need to check the specific bank's rate sheet to know which applies to you.
Key Takeaways
- Money market account rates change weekly and are set by individual banks, not by a central authority, so you must compare rates across multiple banks to find the highest one.
- Online banks typically pay 0.5% to 1.5% more APY than traditional banks because they have lower operating costs.
- The Federal Reserve's benchmark rate is the underlying driver of all money market rates, so when the Fed raises or cuts rates, bank rates follow within days or weeks.
- Some banks pay tiered rates based on your balance, meaning you earn more on deposits above a certain threshold, so read the rate sheet carefully before opening an account.
- The APY shown on a bank's website is the rate for new deposits made today, and that rate may be different next week.
How the Federal Reserve rate affects what you earn
The Federal Reserve sets a target range for the federal funds rate—the interest rate banks charge each other for overnight loans. This rate is not a rate you see directly, but it is the foundation that all other rates rest on. When the Fed raises its target range, banks have less incentive to borrow from each other cheaply, so they raise the rates they pay on deposits to attract more customer money. When the Fed cuts its target range, banks lower deposit rates because they need less customer money.
The Fed does not set your money market rate. It sets the federal funds rate, and banks decide how much of that change to pass on to you. A bank might raise its money market rate by 0.25% when the Fed raises by 0.25%, or it might raise by only 0.10% and keep the difference as profit. This is why two banks can have different rates even when the Fed rate is the same.
The Fed has raised rates significantly since 2022, which is why money market rates are much higher now than they were in 2020 and 2021. If the Fed cuts rates in the future, money market rates will fall. This is not something any individual bank controls—it is a market-wide shift.
Why rates differ between banks
Banks set their own rates based on how much deposit money they need. A bank that has plenty of deposits and does not need more may pay a lower rate because customers have fewer options elsewhere. A bank that is trying to grow and needs more deposits will pay a higher rate to attract them. This is basic supply and demand.
Online banks almost always pay more than traditional banks. An online bank with no physical branches has much lower overhead—no rent, no tellers, no security guards. It can afford to pay you more and still make a profit. A traditional bank with hundreds of branches has to cover all that cost, so it pays less on deposits and charges more on loans.
Bank size also matters. Very large national banks often pay lower rates because they already have plenty of deposits and do not need to compete as hard. Smaller regional banks and online-only banks compete more aggressively on rate to win your business.
Tiered rates and balance thresholds
Some banks use tiered rate structures, meaning you earn different rates on different portions of your balance. For example, a bank might pay 4.00% APY on the first $50,000 and 4.50% APY on anything above that. This encourages you to keep more money in the account.
Other banks pay the same rate on every dollar, no matter how much you have. This is simpler to understand but may mean you earn less if you have a large balance. Before opening an account, look at the rate sheet and see whether the bank uses tiers. If you have $100,000 to deposit, a tiered account might earn you significantly more than a flat-rate account.
A few banks also offer promotional rates—a higher rate for a limited time to new customers. These rates are real, but they usually drop after 3 to 6 months. If you are comparing banks, check whether the rate you are seeing is a promotional rate or the standard rate.
How to find the highest rate for your situation
The best way to find the highest rate is to visit the websites of several banks and compare their published APY for money market accounts. Focus on banks that match your deposit amount and your banking style. If you want to deposit $50,000, compare the rates at online banks, at your current bank, and at one or two regional banks. Write down the APY, the balance tier it applies to, and the date you checked it.
Rates change frequently, so a rate you see today may be different next week. If you find a bank paying significantly more than others, check back in a few days to make sure that rate is still there and not a promotional offer about to expire. Some banks also offer rate-matching guarantees, though these are rare and usually apply only if you find a higher rate at a competitor within a short window after opening.
Keep in mind that a money market account usually comes with a debit card and check-writing privileges, unlike a regular savings account. If you need those features, that bank's rate matters more. If you just want to park money safely and earn interest, you can afford to be pickier about which bank you choose and focus purely on rate.
What happens to your rate over time
Once you open a money market account, your rate is not locked in. The bank can lower your rate at any time, and it will notify you before doing so (usually 30 days' notice). If the Fed cuts rates, expect your bank to cut your rate within a few weeks. If the Fed raises rates, your bank may or may not raise your rate—it depends on whether the bank wants to compete for more deposits.
This is why it makes sense to check rates every few months. If your bank has dropped its rate significantly and competitors are paying much more, you can move your money to a higher-paying bank. There is no penalty for closing a money market account and opening one elsewhere, as long as you do not exceed the withdrawal limits during the transfer.
Some people move their money between banks several times a year to chase the highest rate. This works if you have the time and do not mind the small hassle of transferring funds. Others pick a bank and stay put, accepting a slightly lower rate in exchange for simplicity. Both approaches are reasonable.
The relationship between money market rates and other savings products
Money market accounts usually pay slightly less than certificates of deposit (CDs) with the same term, because you can withdraw from a money market account whenever you want. A CD locks your money away for a set period—3 months, 6 months, 1 year, 5 years—and pays a higher rate in exchange. If you need access to your money, a money market account is worth the lower rate. If you can lock money away, a CD usually pays more.
Regular savings accounts pay much less than money market accounts—often 0.01% to 0.05% APY. The difference is huge. A money market account is almost always the better choice if you want to earn interest on money you are not spending.
High-yield savings accounts are a third option. They pay rates very similar to money market accounts—sometimes identical—but without the debit card or check-writing features. If you do not need those features, a high-yield savings account and a money market account are functionally the same, and you should pick whichever one pays more.
Frequently Asked Questions
Can a bank lower my rate without warning?
No. Banks must notify you at least 30 days before lowering the rate on an existing account. You will receive a notice by mail or email. You can then decide whether to move your money to a different bank or accept the lower rate. The bank cannot lower your rate and then tell you afterward.
Is the APY I see on the website the rate I will actually get?
Yes, if you open the account today. The rate shown is the current rate for new deposits. However, that rate may change by tomorrow or next week. Once your account is open, your rate will change only if the bank notifies you of a change, which it must do 30 days in advance.
Why do online banks pay more than my current bank?
Online banks have much lower operating costs because they do not maintain physical branches. They can afford to pay you more interest and still make a profit. Traditional banks have to cover the cost of buildings, employees, and security, so they pay less on deposits and charge more on loans.
What happens to my money market rate if the Fed cuts rates?
Your bank will lower your rate within a few weeks of a Fed rate cut. The exact timing and amount depend on the bank. Some banks cut rates quickly and by the full amount. Others cut slowly or by less than the Fed cut. You should compare rates at other banks to see if you can earn more elsewhere.
Is it worth moving my money to chase a higher rate?
It depends on the difference and your balance. If another bank is paying 0.5% more APY and you have $50,000, that is $250 per year in extra interest. If the difference is 0.1% and you have $10,000, that is $10 per year—probably not worth the effort. Calculate the annual difference and decide if it is worth the time to transfer.
