Money market accounts (MMAs) sit between savings and checking — earn HYSA-like interest, often with check-writing or debit card. The 2026 reality: the best MMAs (Vio Bank, Discover) match or beat top HYSAs while adding spending features. The worst MMAs (most big-bank MMAs) pay under 1% — those should be ignored.

MMA vs HYSA — the real difference
Money market account:
- Often allows check-writing or debit card
- May have higher minimum balances
- FDIC-insured
High-yield savings:
- No checks, no debit (typically)
- Often $0 minimum
- FDIC-insured
In 2026 with most top HYSAs at 4.40–4.85% and top MMAs at 4.50–4.65%, the rate difference is small. Pick MMA if you need check-writing flexibility; pick HYSA if pure savings.

What's NOT worth your money
- Big-bank MMAs paying under 1% APY — wealth tax on inattention
- MMAs with $5k+ minimums for top APY — rate cliff penalizes you
- MMAs with monthly maintenance fees — modern alternatives are $0
- "Premier" MMA tiers requiring large deposits — alternatives have no minimum
- Money market mutual funds in retail brokerages — different product, technically not FDIC-insured (though SIPC + Treasury-backed for major funds)
FAQ
Are MMAs FDIC-insured?
Yes — same $250k per depositor per bank as HYSAs.
Can I write unlimited checks from an MMA?
Usually limited to 6 transactions/month per Reg D (relaxed during pandemic, but most banks still cap).
Should I pick MMA or HYSA?
HYSA for pure savings, MMA if you want occasional check-writing for the same money.
Best for emergency fund?
Either — pick higher APY. We recommend HYSA for simplicity.
MMA vs Treasury bills?
T-bills (US government debt) at 5%+ are state-tax exempt, slightly higher than top MMAs. More steps to buy/sell.
Will rate change after I open?
Yes — APY adjusts with Fed funds rate.
