Sponsored
Money market accounts (MMAs) blend the safety of a savings account with the earning power of short‑term investments. In 2026, competition is fierce, and a handful of banks and credit unions are offering APYs that can rival many CDs while still providing liquidity. Below we dive into the top picks, explain what to look for, and give you a clear verdict so you can park your cash where it belongs.
What Makes a Money Market Account Competitive?
Before we rank the accounts, it’s essential to understand the factors that drive value:
- APY (Annual Percentage Yield): The higher, the better. Look for tiered rates that reward larger balances.
- Minimum Balance Requirements: Some institutions waive fees only if you keep a certain amount.
- Fees & Restrictions: Monthly maintenance fees, transaction limits, and early withdrawal penalties can eat into earnings.
- FDIC/NCUA Insurance: Guarantees safety up to $250,000 per depositor.
- Accessibility: Mobile app, online banking, and check‑writing capabilities.
