Certificates of deposit from major banks offer rates of up to 4.25% APY as of Aug. 28, 2026, with terms ranging from four to 15 months. American Express leads the featured group with a 4.25% APY on a 10-month CD and no minimum deposit, followed by Citibank at 4.15% for 12 months and Capital One at 4.00% for 12 months. Chase, Bank of America and Wells Fargo offer lower base rates, although some products provide higher jumbo or relationship APYs. The major-bank rates are distinct from the broader market list, where top-performing CDs reach 4.50% APY. CDs lock in an interest rate for a specified term but generally charge early-withdrawal penalties, making the term, APY, minimum deposit, insurance coverage and liquidity needs important considerations. CD laddering can stagger maturities to preserve access to portions of the deposit, while FDIC or NCUA insurance generally determines deposit safety rather than the size of the bank.
