The banks and credit unions offering the best rates change weekly, so there is no permanent answer—but you can find the current leaders in minutes
Money market account rates move constantly because they track the federal funds rate, which the Federal Reserve adjusts throughout the year. When you search for "best rates," you are looking for institutions offering the highest annual percentage yield (APY) on balances you keep liquid. The leaders today may not be the leaders next month.
The fastest way to compare is to visit rate-tracking sites like Bankrate, DepositAccounts, or Money Market Account Rates, which update daily and let you sort by APY, minimum balance, and account features. You can also check your own bank's website and call credit unions directly—many credit unions offer rates competitive with online banks because they have lower overhead costs.
The highest rates almost always come from online banks and credit unions rather than brick-and-mortar banks. Online institutions like Marcus, Ally, and American Express Personal Savings have no branch network to maintain, so they pass savings to depositors. Credit unions, especially those in larger networks like CO-OP or Allpoint, can offer comparable rates without the "online only" limitation.
Key Takeaways
- Online banks and credit unions consistently offer higher money market rates than traditional banks because they have lower operating costs.
- Rate-tracking websites like Bankrate and DepositAccounts update daily and let you filter by APY, minimum deposit, and withdrawal limits.
- The highest rate today may not be the highest next month, so checking rates every few months makes sense if you are holding a large balance.
- Credit unions may offer rates as high as online banks while giving you access to physical branches and ATM networks through CO-OP or Allpoint.
- Minimum balance requirements and withdrawal restrictions vary widely, so compare the full account terms, not just the APY.
How to use rate-tracking sites to find the best current rates
Bankrate, DepositAccounts, and Money Market Account Rates all display current APYs from dozens of institutions, updated daily or multiple times per day. Each site lets you filter by minimum deposit amount, account type, and whether you want FDIC insurance (banks) or NCUA insurance (credit unions). Start by entering your target deposit amount—a $50,000 balance may may have access to for a higher tier than $10,000, and some institutions offer tiered rates.
Once you narrow the list, visit the bank's or credit union's website directly to confirm the rate is still current and to read the fine print on withdrawal limits. Money market accounts typically allow three to six withdrawals per month before fees kick in, though this rule varies by institution. Some banks waive the limit if you maintain a certain balance or use their debit card for purchases.
Check whether the institution is FDIC-insured (banks) or NCUA-insured (credit unions). Both types of insurance protect your deposit up to $250,000 per account holder per institution, so this is not a reason to choose one over the other—it is a baseline requirement.
Why online banks lead on rates but credit unions offer a middle ground
Online banks have no physical locations, no tellers, and no branch maintenance costs. They pass those savings directly to customers through higher APYs. Marcus, Ally, American Express Personal Savings, and Vanguard Money Market Fund are examples of institutions that compete almost entirely on rate and customer service rather than convenience.
Credit unions operate as member-owned cooperatives, so profits return to members rather than shareholders. A credit union with 50,000 members can offer competitive rates without the scale of a national bank. The trade-off is that you may have fewer branches or ATMs unless the credit union belongs to a shared branching network like CO-OP (which has over 30,000 ATMs) or Allpoint (which has over 55,000 ATMs worldwide).
If you want the highest rate and do not need to visit a branch, an online bank is usually the answer. If you want a high rate and the option to deposit cash or speak to someone in person, a credit union in a large network often splits the difference.
What to check beyond the APY when comparing accounts
The annual percentage yield is the headline number, but the account terms matter just as much. Check the minimum opening deposit—some institutions require $1,000 or $2,500 to open, while others have no minimum. If you plan to add money regularly, confirm whether the rate applies to all deposits or only your opening balance.
Withdrawal limits are the second critical detail. Federal rules no longer cap withdrawals, but individual banks and credit unions set their own limits. Some allow unlimited withdrawals; others cap you at three or six per month before charging a fee (usually $10 per excess withdrawal). If you think you will need to access your money frequently, this matters more than a 0.1% higher APY.
Read the fee schedule carefully. Look for monthly maintenance fees, excess withdrawal fees, overdraft fees, and early closure fees. Some institutions charge $25 to $50 if you close the account within a certain period (often 90 days). A money market account with a 4.50% APY and a $25 monthly fee is worse than one with a 4.40% APY and no fees.
How often rates change and when to shop around
Money market rates move in response to Federal Reserve decisions. When the Fed raises its benchmark rate, banks and credit unions typically raise their APYs within days or weeks. When the Fed cuts rates, institutions lower their APYs just as quickly—sometimes faster. This means the best rate for your money can shift significantly over a few months.
If you are holding a large balance (over $50,000), it makes sense to check rates every two to three months. If you are holding under $10,000, the difference between a 4.25% APY and a 4.50% APY is small enough that you can check once or twice a year. The effort of moving money between institutions has a cost in time and attention, so weigh that against the actual dollar gain.
Some people use a "ladder" approach: they keep their emergency fund in a high-rate money market account and move money into it from checking as rates rise, then move it out if rates fall and they find a better home. This works if you are comfortable managing multiple accounts, but it is not necessary for most people.
Regional credit unions versus national online banks
A local or regional credit union may offer a rate within 0.25% of the national leader, and you get the benefit of walking into a branch to deposit cash or speak to a loan officer. If you already bank at a credit union, check their money market rate first—you may find it is competitive enough that switching is not worth the hassle.
National online banks offer the absolute highest rates most of the time, but they have no branch network. You deposit by transfer or mobile check deposit, and you withdraw by transfer. This works perfectly well for money you plan to leave alone, but it is slower if you need cash in hand.
The choice often comes down to how you plan to use the account. If it is a true emergency fund you hope never to touch, an online bank's 4.50% APY beats a credit union's 4.30% APY by a meaningful margin over time. If it is money you might need to access quickly in person, a credit union's 4.30% APY plus branch access may be worth the trade-off.
Frequently Asked Questions
Do I have to move my money to a new bank to get a better rate?
Yes, you will need to open a new account at the institution offering the better rate. You can transfer money electronically between banks in one to three business days, or you can move it gradually by depositing new savings into the higher-rate account. You do not have to close your old account immediately.
What if the rate drops after I open the account?
Your rate will drop along with it—money market rates are variable, not fixed. The bank or credit union will notify you before the change takes effect. If rates fall significantly, you can move your money to a different institution, but you will pay the cost in time and attention. This is why comparing rates every few months makes sense.
Is an online bank safe if it has no physical location?
Yes, as long as it is FDIC-insured. FDIC insurance protects your deposit up to $250,000 regardless of whether the bank has branches. You can verify FDIC insurance by searching the bank's name on the FDIC's Bank Find tool. Online banks are regulated the same way as traditional banks.
Can I move money between money market accounts without penalty?
You can transfer money out of a money market account without penalty, but some institutions charge a fee if you close the account within 90 days of opening it. Read the terms before opening. Transfers between accounts take one to three business days, so plan ahead if you need the money quickly.
Should I put all my savings in a money market account?
Money market accounts are best for money you want to keep liquid and accessible—typically your emergency fund or short-term savings. For money you will not need for years, a high-yield savings account or certificate of deposit (CD) may offer a better rate. For long-term investing, stocks and bonds historically outpace savings accounts.
