Santander Bank’s CD page showed 4.25% APY on an 11-month CD and 4.00% APY on an 18-month CD when we checked on October 25, 2026. A $500 minimum deposit is needed to open one and receive the advertised APY, and CDs can only be opened in a branch. Santander says published rates can change without notice and may differ by location, so confirm the rate for your ZIP code before opening.

Early Withdrawal Penalties

|---|---|
| 3 to 12 months | 90 days of interest on the principal withdrawn |

Renewal and Grace Period
On the maturity date, a CD automatically renews into the closest term available at the interest rate for that term. During the 10-calendar-day grace period after maturity you can choose a new term and rate, withdraw funds without penalty, add funds, or close the account. Santander says it mails a renewal notice at least 20 days before maturity.
Santander vs. Online Banks
Compare Santander’s APY for your term and ZIP code with online banks before you open, and weigh the branch-only opening. For scale, the FDIC’s national average 12-month CD rate was 1.76% as of October 19, 2026, and Marcus listed 4.40% APY on a 12-month CD (October 15, 2026).
