Merrill Lynch does not offer a standalone high yield savings account
Merrill Lynch, the investment and wealth management 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 sweep account — money moves automatically into whatever vehicle the firm has chosen, usually a money market fund or a Bank of America deposit account. You do not choose the rate or the account type yourself.
This matters because sweep rates change without notice and are typically lower than what you would find at an online bank or credit union. Merrill Lynch's sweep options are designed for investors who need a place to park cash between trades or while waiting to invest, not for people building a savings strategy.
Key Takeaways
- Merrill Lynch automatically sweeps uninvested cash into money market funds or Bank of America accounts, not into a high yield savings account you control.
- Sweep rates are set by Merrill Lynch and change frequently, and they are usually lower than rates at online banks or credit unions.
- If you want a high yield savings account, you will need to open one at a separate institution and transfer money there yourself.
- Merrill Lynch's cash management is built for investors, not savers, so it is not the right tool if your goal is to earn interest on savings.
How Merrill Lynch's sweep account works
When you deposit money into a Merrill Lynch brokerage account, any cash that is not invested goes into a sweep vehicle. The firm decides where that money goes — typically into a money market mutual fund or a Bank of America savings or money market account. You receive whatever rate that vehicle pays, and you have limited control over which option is used.
The sweep rate fluctuates based on market conditions and Merrill Lynch's internal decisions. During periods of higher interest rates, sweep rates may be more competitive. During low-rate environments, they can fall significantly behind what online banks offer. Merrill Lynch does not advertise these rates prominently, and they are not may provide.
If you want your cash to earn a specific rate or sit in a particular type of account, you would need to move it out of Merrill Lynch entirely and into a separate high yield savings account at another bank.
Why Merrill Lynch's approach differs from high yield savings
High yield savings accounts are designed specifically to hold cash and pay competitive interest. They are FDIC-insured up to $250,000 per depositor per bank, and the rate is fixed (or clearly stated as variable). You can withdraw money without penalty, and the account exists solely to earn you interest.
Merrill Lynch's sweep account serves a different purpose: it is a holding tank for an investment account. The firm's priority is managing investments and executing trades, not competing on savings rates. The sweep is a convenience feature, not a savings product.
If you are a Merrill Lynch customer and want to earn a higher rate on cash, you have two options: keep money in a sweep account and accept whatever rate Merrill Lynch offers, or move cash to a separate high yield savings account at an online bank, credit union, or traditional bank and manage two accounts.
Where to find high yield savings if you bank with Merrill Lynch
Online banks like Marcus, Ally, and American Express Personal Savings typically offer rates that are higher than Merrill Lynch sweeps. Credit unions often have competitive rates as well, especially if you are a member. Traditional banks like Chase and Bank of America (Merrill Lynch's parent company) also offer high yield savings products, though rates vary by account type and balance.
You can open a high yield savings account at any of these institutions without closing your Merrill Lynch account. Money moves between accounts via ACH transfer, which usually takes one to three business days. This approach lets you keep your investments at Merrill Lynch while earning a better rate on cash you want to save.
The trade-off is managing two separate accounts and tracking balances across institutions. For some people, that inconvenience is worth the higher interest rate. For others, the simplicity of keeping everything in one place outweighs the rate difference.
What to check if you already have cash at Merrill Lynch
Log into your Merrill Lynch account and look for the cash balance or sweep account section. You should see what vehicle your cash is currently in and what rate it is earning. Merrill Lynch publishes sweep rates, though they are not always straightforward to find on the main website — you may need to contact a representative or check your account statements.
Compare that rate to what you could earn at an online bank or credit union. If the difference is significant and you have a substantial cash balance, moving some or all of it to a high yield savings account elsewhere could add up over time. Even a 1% difference on $50,000 means $500 per year in additional interest.
If you decide to move money out, initiate an ACH transfer from Merrill Lynch to your new savings account. The process is straightforward and does not affect your brokerage account or any investments you hold.
Frequently Asked Questions
Can I earn interest on my Merrill Lynch cash balance?
Yes, but only through the sweep account Merrill Lynch assigns to you. You cannot choose a high yield savings account within Merrill Lynch. The rate you earn depends on what vehicle the firm sweeps your cash into and changes based on market conditions.
Is my cash at Merrill Lynch insured if the company fails?
If your cash is swept into a Bank of America deposit account, it is FDIC-insured up to $250,000. If it is swept into a money market fund, it is not FDIC-insured but is protected under different securities rules. Check your account to see which sweep vehicle you are in.
Can I move my cash to a high yield savings account and keep my Merrill Lynch investments?
Yes. You can open a high yield savings account at another bank and transfer cash there via ACH while keeping your brokerage account and investments at Merrill Lynch. The two accounts operate independently.
How often do Merrill Lynch sweep rates change?
Sweep rates can change daily or weekly depending on market conditions. Merrill Lynch does not announce rate changes in advance. You can check your current rate in your account or by contacting a representative.
What happens to my sweep account if I stop trading?
Your sweep account continues to exist and earn whatever rate Merrill Lynch assigns, even if you are not actively trading. You can leave cash there indefinitely, but you will likely earn more at a dedicated high yield savings account elsewhere.
