When parking cash reserves to earn top-tier yields, savers often debate between High-Yield Savings Accounts (HYSAs) and Money Market Accounts (MMAs). While both offer FDIC insurance and competitive interest, key differences in liquidity and payment capabilities set them apart.
Feature-by-Feature Comparison
| Feature | High-Yield Savings Account (HYSA) | Money Market Account (MMA) |
|---|---|---|
| Interest Rates (APY) | Typically slightly higher (4.25% – 5.15%) | Competitive (4.00% – 5.00%) |
| Debit Card Access | Rare (ACH transfer only) | Standard feature |
| Check-Writing Privileges | No | Yes (physical checkbook provided) |
| Deposit Insurance | FDIC/NCUA up to $250,000 | FDIC/NCUA up to $250,000 |
Crucial Distinction: MMAs vs Money Market Mutual Funds
Do not confuse a bank Money Market Account (MMA) with a brokerage Money Market Mutual Fund (MMF) (like Vanguard’s VMFXX or Fidelity’s SPAXX). MMAs are FDIC-insured deposit accounts. MMFs are SIPC-protected mutual funds that invest in ultra-short-term US Treasuries and debt obligations.
For most households, keeping an emergency fund in an online HYSA provides the ideal balance of yield and separation from impulse spending.
