What Is a Cash Management Account?
A cash management account (CMA) is a hybrid financial account offered by brokerage firms and fintech companies that combines the features of a checking account, a high-yield savings account, and investment access — all in one place.
Unlike traditional bank accounts, CMAs sweep uninvested cash to a network of FDIC-member partner banks, providing $1 million to $8 million in total FDIC coverage — far more than the $250,000 limit at a single bank.
As of September 2026, cash rates on CMAs and related brokerage cash products ranged roughly 3.3–4.5% APY, depending on the provider and product, while offering a debit card, check writing, and bill pay. Rates change frequently — confirm the current figure before opening an account.
CMA vs Bank Account vs Brokerage Account
| Feature | Cash Management Account | Bank Savings Account | Brokerage Account |
|---|---|---|---|
| Interest on cash (Sept 2026) | ~3.3–4.5% APY | ~0.01% (big bank) to ~4.50% (top HYSA) | ~3.3–3.7% (govt money market fund) |
| Debit card | Yes (most providers) | No (savings accounts) | Sometimes |
| Check writing | Yes (most providers) | No | No |
| Bill pay | Yes | No | No |
| FDIC coverage | $1M–$8M+ via sweep | $250K per bank | SIPC (not FDIC) |
| ATM access | Yes (often fee-free) | Limited | Rare |
| Investment access | Integrated or linked | No | Yes |
| Where held | Brokerage/fintech | FDIC bank | FDIC bank + SIPC |

How Cash Management Accounts Work
Step 1: You deposit cash. You transfer money into your CMA just as you would to a bank account.
Step 2: The provider sweeps cash. The CMA provider (Fidelity, Wealthfront, etc.) automatically moves your cash to a network of FDIC-member partner banks — typically 4–32 banks.
Step 3: FDIC coverage multiplies. Each partner bank insures up to $250,000 of your money. With 4 partner banks, you have $1 million in coverage. With 32 banks, you have $8 million in coverage.
Step 4: You earn interest. The partner banks pay interest on your cash. The CMA provider passes this interest to you (minus a small spread).
Step 5: Use it like a checking account. You can spend with a debit card, pay bills, write checks, and move money to investments — all without leaving the platform.
Cash Management Accounts and Related Cash Products: What to Compare
Rates and products change often enough that a fixed table of provider rates goes stale within weeks. As of September 2026, government money market funds used as brokerage “core” cash positions (Fidelity’s SPAXX, Vanguard’s VMFXX, Schwab’s SWVXX) were yielding roughly 3.3–3.7%, while Schwab’s default bank sweep paid only around 0.45% and top standalone online HYSAs were paying roughly 4.00–4.50%. Dedicated CMA products from robo-advisors and fintechs (Wealthfront, Betterment, SoFi, and similar) have historically priced closer to top HYSA rates than to money market fund yields, but the gap between any two providers can shift by more than a full percentage point within a year. Before choosing, compare the current published rate at each of the providers you’re considering — don’t rely on a rate table more than a few weeks old.
Note: Default bank-sweep rates (as opposed to a provider’s flagship CMA or money market fund rate) are often much lower — check which specific cash vehicle a given rate applies to before assuming it’s the one your balance will actually sit in.
Pros of Cash Management Accounts
High FDIC coverage. The multi-bank sweep structure can provide $1 million to $8 million in FDIC coverage — crucial for large deposits.
Competitive rates. Top CMAs often come close to the best HYSAs, though as of September 2026 top standalone HYSAs were generally paying somewhat more than brokerage money market fund sweeps.
All-in-one convenience. Checking, savings, and investing access in one place reduces the need for multiple accounts.
No monthly fees. Most major CMAs charge no monthly maintenance fee.
Large ATM networks. Fidelity, for example, reimburses all ATM fees worldwide. Several other providers offer large fee-free ATM networks — confirm current terms with each provider.
Cons of Cash Management Accounts
Tied to a brokerage. CMAs work best for existing brokerage customers. If you don’t invest, the integration advantage is smaller.
Fewer physical locations. Most CMA providers are online-only (with the exception of Schwab/Fidelity, which have branch offices).
Rate variability. CMA rates are typically tied to money market conditions and can change more frequently than promotional HYSA rates.
Complexity. Managing cash, investments, and banking in one place can be simpler or more confusing depending on the person.
Who Should Use a CMA?
Good fit if:
- You invest at Fidelity, Schwab, Wealthfront, Betterment, SoFi, or Robinhood
- You have more than $250,000 in cash and need FDIC coverage above a single bank’s limit
- You want to simplify — fewer accounts, fewer logins
- You want checking-account features along with a competitive cash rate
Less ideal if:
- You prefer keeping banking separate from investing
- You need frequent cash deposits (same limitation as online banks)
- You need in-person bank branch services
- You want the single highest available cash rate, which as of September 2026 was more often found at a standalone top HYSA
