A cash management account (CMA) and a high-yield savings account (HYSA) both earn competitive interest on idle cash — but they work differently. The right choice depends on whether you need checking-like access to your money or are content with a pure savings account. Here is how they compare.
What Is a Cash Management Account?
A cash management account is a hybrid financial product, typically offered by a brokerage or fintech company rather than a bank. CMAs combine the features of a checking account — debit card, check writing, ACH transfers, sometimes ATM reimbursements — with an interest rate that competes with high-yield savings.
Where you find CMAs: Fidelity, Wealthfront, Betterment, Schwab, and Robinhood all offer cash management products. These are not bank accounts — your funds are swept into partner banks overnight to earn interest and gain FDIC protection.
CMA vs. HYSA: Side-by-Side Comparison
| Feature | Cash Management Account | High-Yield Savings Account |
|---|---|---|
| Offered by | Brokerages, fintechs | Banks, credit unions, fintechs |
| APY (2026, competitive) | 3.50–4.50% | 4.00–4.50% |
| Debit card | Usually yes | Usually no |
| Check writing | Usually yes | No |
| Bill pay | Usually yes | No |
| ATM access | Often yes (with reimbursements) | No (transfer to checking needed) |
| FDIC insurance | Up to $500K–$2M+ via sweep | $250,000 per depositor |
| Withdrawal limits | None (checking-like) | None (Fed regs changed in 2020) |
| Joint accounts | Some providers | Most providers |
| Mobile check deposit | Some providers | Some providers |
How Each Account Works
High-Yield Savings Account
A HYSA is a savings-only deposit account at a bank or credit union. You earn a higher APY than a traditional savings account, but you cannot make purchases directly from it. To spend, you transfer funds to a linked checking account.
Best for: emergency funds, short-term savings goals, parking cash you will not touch for weeks at a time.
Cash Management Account
A CMA sweeps your deposits across a network of partner banks each night. During the day, the funds sit at the brokerage and earn interest. Because the brokerage is not itself a bank, your money is swept to actual FDIC-insured banks to qualify for insurance — often multiple banks, increasing your total insured limit.
Best for: investors who want one account for spending and saving, those with large cash balances who want $500K+ in FDIC coverage, and people who want brokerage-adjacent cash management.
FDIC Coverage: A Key CMA Advantage
One major difference: deposit limits.
| Account type | Max FDIC coverage |
|---|---|
| High-yield savings (one bank) | $250,000 |
| Cash management (sweep network) | $500,000–$2,000,000+ |
If you hold more than $250,000 in cash, a CMA with a multi-bank sweep network gives you significantly more FDIC protection than a single HYSA — without requiring multiple bank accounts.
Which Should You Choose?
Choose a HYSA if you:
- Want a simple, dedicated savings account with no distractions
- Keep your spending and saving separate intentionally
- Are building an emergency fund or short-term savings goal
- Prefer to bank with an FDIC-insured bank directly
Choose a CMA if you:
- Already use a brokerage (Fidelity, Schwab, Wealthfront) and want your cash integrated
- Have more than $250,000 in cash and need expanded FDIC coverage
- Want debit card, checks, and bill pay from one account
- Are comfortable with the sweep-bank structure
Worked example: You have $400,000 in cash. At a single bank HYSA, only $250,000 is fully FDIC insured. At a Wealthfront Cash Account with a sweep network covering 40 partner banks, your full $400,000 is insured — at the same or better APY.
