Smaller online banks often beat them with rates up to 5.10%. So why would anyone choose a big bank? Simple: trust, convenience, and relationship perks. If you already bank with them, you might get a bump in your APY or enjoy having all your money in one place. Plus, big banks offer more CD options; from no-penalty to jumbo to IRA CDs. But here’s the catch: longer terms lock you in. If rates go up, you’re stuck unless you pay a penalty. Smart move? Try CD laddering; spread your money across 6, 12, 18, and 24-month terms. That way, you get regular access + steady returns. Bottom line: Big banks = comfort. Smaller banks = higher returns. Pick what fits your risk, access, and peace-of-mind needs.
