Fidelity does not offer a traditional high yield savings account, but it does offer cash management accounts that function similarly
Fidelity does not have a product called a "high yield savings account" in the way that online banks like Marcus or Ally do. However, Fidelity offers cash management accounts that hold your money in money market funds and sweep uninvested cash into interest-bearing vehicles. The most common option is the Fidelity Government Money Market Fund, which holds U.S. Treasury securities and other short-term government debt. Your cash earns interest, and the rate changes with market conditions—it is not locked in like a traditional savings account.
The key difference: Fidelity's cash management is designed for investors who already have a brokerage account or are using Fidelity as their primary financial institution. If you are looking for a standalone savings account where you deposit money and it sits earning interest, Fidelity is not the right fit. If you are already trading stocks or managing investments at Fidelity and want your uninvested cash to earn something rather than sit idle, their cash management options do that work.
Key Takeaways
- Fidelity offers cash management through money market funds and sweep accounts, not a branded high yield savings account product.
- Cash held in Fidelity's Government Money Market Fund earns interest that fluctuates with market rates, currently competitive with online savings accounts but not may provide.
- Fidelity's cash management is built for people who already invest with them or want to consolidate banking and investing in one place.
- If you want a simple, standalone high yield savings account with a fixed or predictable rate, you will need to open an account at an online bank like Marcus, Ally, or American Express Personal Savings.
How Fidelity's cash management accounts work
When you open a Fidelity brokerage account, any cash you deposit that is not invested in stocks, bonds, or funds sits in a default sweep account. Fidelity automatically moves that cash into interest-bearing vehicles—most often the Fidelity Government Money Market Fund. You do not have to do anything; the sweep happens behind the scenes.
The interest rate on money market funds is not fixed. It changes daily based on what the Federal Reserve does with interest rates and what rates the underlying Treasury securities and short-term debt pay. When the Fed raises rates, money market rates go up. When the Fed cuts rates, they go down. You can check Fidelity's current money market fund rates on their website, but they will not be the same next month.
You can withdraw your cash anytime without penalty. There is no lock-in period, no minimum balance requirement (though Fidelity may have account minimums for opening a brokerage account), and no monthly fees for holding cash in the sweep account. The money is also FDIC insured up to $250,000 per account category at Fidelity's partner banks.
How Fidelity's rates compare to online savings accounts
Online banks like Marcus, Ally, and American Express Personal Savings advertise their rates prominently because those rates are their main selling point. They also tend to be simpler: you open an account, deposit money, and it earns a stated APY. Fidelity's money market funds do not work that way—the rate is tied to the market and changes constantly.
In practice, when the Fed is holding rates steady, Fidelity's money market rates and online savings rates are often close to each other. Both move in the same direction when the Fed changes rates. The difference is that online banks may advertise a rate that is good for 30 days or until they change it, while Fidelity's rate updates daily. If you are comparing rates, you need to check both on the same day to see which is higher at that moment.
Fidelity does not publish a may provide minimum rate. If rates fall sharply, your money market fund rate falls with them. Online savings accounts work the same way—they can lower their rates anytime—but they tend to advertise the current rate more clearly so you know what you are getting into.
When Fidelity's cash management makes sense
Fidelity's cash management is most useful if you are already investing with them. If you have a brokerage account and regularly move money in and out to buy stocks or funds, having your uninvested cash earn interest automatically is convenient. You do not have to open a separate savings account at another bank and transfer money back and forth.
It also makes sense if you want to consolidate your banking and investing in one place. Some people prefer having one login, one statement, and one customer service line for all their money. Fidelity can provide that if you use them for both investing and cash management.
Fidelity's cash management is less useful if you are looking for a pure savings account—a place to park money you are not investing and do not plan to touch for a while. In that case, an online savings account at Marcus, Ally, or American Express is simpler and often clearer about what rate you will earn.
FDIC insurance and safety of your cash at Fidelity
Cash held in Fidelity's sweep accounts is protected by FDIC insurance through Fidelity's partner banks. The coverage limit is $250,000 per account category. This means if Fidelity or one of its partner banks fails, your cash up to $250,000 is protected by the federal government.
The money market funds themselves are not FDIC insured—they are investments in Treasury securities and other short-term debt. However, because those securities are backed by the U.S. government, the risk is very low. Money market funds are considered one of the safest investments available, but they are not the same as a bank savings account.
If you have more than $250,000 in cash at Fidelity, ask their customer service how the insurance works across multiple accounts or account types. The rules can be complex, and Fidelity can explain your coverage.
Other cash options at Fidelity
Beyond the Government Money Market Fund, Fidelity offers other sweep options. Some accounts allow you to choose between a money market fund, a sweep to a money market deposit account (MMDA) at a partner bank, or even a sweep to a short-term bond fund. The options depend on the type of Fidelity account you have.
If you are opening a new account at Fidelity, ask about all available sweep options. Some may offer slightly higher rates than others, or they may have different features like check-writing or debit card access. Fidelity's customer service can walk you through what is available for your account type.
Frequently Asked Questions
Can I earn interest on cash at Fidelity without investing?
Yes. You can open a Fidelity brokerage account, deposit cash, and leave it in the sweep account earning interest without ever buying a stock or fund. However, Fidelity's main business is investing, so their cash management is designed as a feature for investors, not as a standalone savings product.
What is the current interest rate on Fidelity's money market fund?
Fidelity's money market fund rate changes daily and is not published in a single place on their website. Log into your Fidelity account or call their customer service to see the current rate. You can also compare it to rates at online banks on the same day to decide which is better for you right now.
Can I withdraw my money from Fidelity's cash management account anytime?
Yes. There are no withdrawal restrictions or penalties. You can move money out to your bank account or spend it using a Fidelity debit card (if your account includes one) whenever you want.
Is my money safer at Fidelity or at an online savings bank?
Both are safe. Cash at Fidelity is FDIC insured up to $250,000 through partner banks. Cash at online savings banks is also FDIC insured up to $250,000. The main difference is that online banks are simpler if you only want a savings account, while Fidelity is better if you are also investing.
What happens to my money market fund if interest rates drop?
Your interest rate will drop along with market rates. You will earn less interest, but your principal (the money you deposited) stays the same. Money market funds do not lose value the way bond funds can when rates rise, so your cash is safe even if rates fall.
