With inflation still a threat and market volatility on the rise, a high-interest savings account remains one of the safest ways to protect and grow your money. In 2025, both UK and USA banks are offering competitive interest rates ranging from 4.25% to 5.20%, making this the ideal time to upgrade where you store your cash.
Here’s a breakdown of the top-performing savings accounts in both countries — no gimmicks, no hidden fees.

- Above-average interest (AER/APY)
