Merrill Lynch does not offer high yield savings accounts
Merrill Lynch, the wealth management and brokerage division of Bank of America, does not have a dedicated high yield savings product. If you hold cash at Merrill Lynch, it sits in a money market fund or a sweep account that moves your uninvested cash into money market instruments—not a savings account earning a stated APY.
This matters because the rate you earn depends on what Merrill Lynch puts your cash into, not on a rate they publish for a savings product. You do not control where the sweep goes, and the yield fluctuates with market conditions and the fund's holdings. If you came to Merrill Lynch specifically looking for a high yield savings account, you will need to move that cash to a different institution.
Key Takeaways
- Merrill Lynch offers money market funds and sweep accounts for uninvested cash, not high yield savings accounts with a fixed APY.
- The rate you earn on cash at Merrill Lynch depends on the underlying money market fund or sweep vehicle, which changes based on market conditions and fund composition.
- You cannot choose which money market fund your cash goes into—Merrill Lynch assigns it based on your account type and balance.
- If you want a high yield savings account, you will need to open one at a bank or online institution that offers that product separately from brokerage services.
How Merrill Lynch handles uninvested cash
When you deposit money into a Merrill Lynch brokerage account and do not when ready invest it, the cash goes into a sweep account. The sweep automatically moves your cash into money market funds or money market instruments—short-term bonds, Treasury bills, and commercial paper—rather than holding it as a deposit.
Merrill Lynch offers different sweep options depending on your account type. The most common is the Merrill Lynch Insured Deposit Sweep, which moves cash into deposit accounts at partner banks up to the FDIC insurance limit. Another option is the Merrill Lynch Money Market Sweep, which invests in money market funds. Your account type and balance tier determine which sweep you get, and you cannot straightforward choose the highest-yielding option.
The rate you earn is not may provide and is not published as an APY the way a savings account rate would be. Instead, it reflects the yield of the underlying money market fund or the rates the partner banks are offering at that moment. When the Federal Reserve cuts rates, these yields fall. When rates rise, they may rise too—but with a lag, because money market funds hold bonds purchased at earlier rates.
Why this is different from a high yield savings account
A high yield savings account at a bank or online institution is a deposit product. You own the account, the bank holds your money, and the bank publishes an APY that applies to your balance. That rate is what you earn, and it changes only when the bank decides to change it. You can move your money to another bank if the rate drops.
A Merrill Lynch money market sweep is not a deposit account you own. It is an investment vehicle that holds your cash. You do not earn a stated rate; you earn whatever the fund yields. You cannot move your cash to a different sweep if you do not like the yield—Merrill Lynch assigns it based on your account structure. And because money market funds hold bonds, their yields lag behind rate changes in the broader market.
For someone who wants to park cash and know exactly what they will earn, a high yield savings account is simpler and more transparent. For someone who already has a Merrill Lynch brokerage account and wants their uninvested cash to earn something rather than sit idle, the sweep is a default option—but it is not a substitute for a dedicated savings product.
What rates Merrill Lynch sweeps actually earn
Merrill Lynch does not publish a single sweep rate the way a bank publishes a savings APY. The rate depends on which sweep vehicle you are in and what that vehicle holds at any given time. The Insured Deposit Sweep rate reflects what partner banks are paying on deposits, which varies by bank and changes frequently. The Money Market Sweep rate reflects the yield of the underlying money market fund.
You can see the current yield of a money market fund by looking at its prospectus or fact sheet on Merrill Lynch's website, but this is a historical yield, not a forward-looking rate. The fund's yield changes as bonds mature and are replaced, and as interest rates move. There is no way to know in advance what you will earn over the next month or year.
If you want to compare what you would earn at Merrill Lynch versus a high yield savings account elsewhere, you would need to look up the current money market fund yield and compare it to the APY offered by savings institutions. In most market environments, high yield savings accounts at online banks have offered competitive or higher rates than Merrill Lynch money market sweeps, with the added benefit of a may provide rate and FDIC insurance.
Where to open a high yield savings account if you need one
If you want a high yield savings account, you will need to open one at an institution that offers that product. Online banks and some traditional banks offer savings accounts with published APYs that are updated regularly. These accounts are FDIC insured up to $250,000 and allow you to move your money to another bank if rates drop.
You can open a high yield savings account at the same time you hold a Merrill Lynch brokerage account. They are separate products at separate institutions. Some people keep a high yield savings account for emergency funds or short-term goals, and a Merrill Lynch account for investing. Others use a savings account as a cash sweep for their brokerage account, moving money in and out as needed.
The choice depends on how much cash you typically hold uninvested, how often you move money in and out, and whether you want the simplicity of a single institution or the flexibility of keeping accounts at multiple places. There is no rule that says you must choose one or the other.
FDIC insurance and safety of Merrill Lynch cash
Cash held in a Merrill Lynch Insured Deposit Sweep is FDIC insured because it sits in deposit accounts at partner banks. The sweep is designed to keep your balance under the $250,000 FDIC limit at any single bank, spreading larger balances across multiple partner banks so that all of it is covered.
Cash held in a Merrill Lynch Money Market Sweep is not FDIC insured because money market funds are not deposits. However, money market funds are required by the Securities and Exchange Commission to hold only high-quality, short-term securities—Treasury bills, commercial paper, and similar instruments. The risk is low, but it is not zero, and it is not the same as FDIC insurance.
If safety and insurance are your primary concerns, the Insured Deposit Sweep is the safer choice within Merrill Lynch. But if you want both insurance and a high yield, a high yield savings account at another institution may serve you better, because you can see the rate in advance and move your money if it drops.
Frequently Asked Questions
Can I earn a higher rate on cash at Merrill Lynch if I have a larger balance?
Merrill Lynch does not tier rates based on balance size the way some banks do. Your sweep rate depends on which sweep vehicle you are assigned to and what that vehicle yields at the time. A larger balance does not unlock a higher rate; it may straightforward be spread across more partner banks in the Insured Deposit Sweep to stay within FDIC limits.
What happens to my cash if I do not invest it at Merrill Lynch?
Your cash automatically goes into a sweep account—either the Insured Deposit Sweep or the Money Market Sweep, depending on your account type. You do not have to do anything. The sweep is automatic, and you can withdraw your cash at any time without penalty. The rate you earn is whatever the sweep vehicle yields at that time.
Can I move my Merrill Lynch cash to a high yield savings account and keep my brokerage account?
Yes. You can open a high yield savings account at another bank and keep your Merrill Lynch brokerage account open. You would move cash out of Merrill Lynch to the savings account when you want to earn a higher rate, and move it back into Merrill Lynch when you are ready to invest. There is no requirement to keep all your cash in one place.
Is a money market fund safer than a high yield savings account?
A money market fund is not FDIC insured, but it is required to hold only high-quality short-term securities, so the risk is low. A high yield savings account is FDIC insured up to $250,000. If safety is your main concern, FDIC insurance is the stronger may provide, but both are considered low-risk options for cash.
Why does Merrill Lynch not offer a high yield savings account?
Merrill Lynch is a brokerage and wealth management firm, not a retail bank. Its business model is built around investing and trading, not taking deposits. The sweep accounts are designed to handle uninvested cash efficiently, not to compete with banks on savings rates. If you want a savings account, you need to use a bank.
