Is a high-yield savings account FDIC insured?

Yes. High-yield savings accounts at FDIC-member banks are insured up to $250,000 per depositor. Your principal cannot decrease due to market movements — a key difference from money market funds, which are not FDIC insured.

Does the advertised APY require a minimum balance?

It depends on the institution. Some high-yield savings accounts pay the same rate on all balances (no tiers), while others require a minimum daily balance to earn the top rate. Check the bank's disclosure page before opening.

How often does a savings APY change?

High-yield savings rates are variable — they move in response to Federal Reserve policy. Rates typically adjust within weeks of a Fed decision. SwitchWize tracks rates daily; the figure on this page reflects the most recently observed rate.

Can I lose money in a high-yield savings account?

No. Your deposited principal is protected by FDIC insurance up to $250,000. The APY is variable and will change over time, but that only affects future interest earned — never your principal.

How does a high-yield savings account differ from a money market account?

Both pay competitive variable rates and are FDIC insured, but money market accounts sometimes include check-writing or a debit card. High-yield savings accounts typically offer fewer transaction features but often pay a higher APY. Compare current rates for both before deciding.

Is the interest taxable?

Yes. Interest earned in a high-yield savings account is fully taxable at both federal and state levels. You'll receive a 1099-INT for any year you earn $10 or more. Unlike Treasury money market fund income, savings interest has no state-tax exemption.

Main catch

Alliant Credit Union's APY is variable, and transfer or cash-access details still need provider confirmation before opening.

The APY is competitive enough that access, confidence, and transfer rules may matter more than a tiny rate difference.
