A Strong Rate with Short-Term Flexibility

Earn a fixed rate for three months without making a long-term commitment.

With OMB Bank’s 4.05% APY* 3-month CD, you can earn a predictable return over a short term while keeping the opportunity to reconsider your options sooner. Your rate is fixed for the full three-month term, and interest compounds at maturity. When the CD matures, you’ll have a 10-calendar-day grace period to withdraw funds, add funds or choose another CD without an early withdrawal penalty. If you take no action, the CD will automatically renew at our current 3-month board rate.

Available online nationwide or at any OMB Bank branch, this CD may be a good fit for savers comparing short-term CD options or those who want to avoid a longer commitment. A 3-month CD can also be incorporated into a CD laddering strategy, creating recurring opportunities to access or reinvest your savings as individual CDs mature. For a closer look at the advantages and tradeoffs, read why a 3-month CD can make sense in today’s rate environment.

A Straightforward Renewal Process

Know when your CD matures, what happens next and which options are available to you.

When your 3-month CD reaches maturity, you’ll have a 10-calendar-day grace period to decide what to do next. During that period, you may withdraw funds, add funds or choose another CD without an early-withdrawal penalty.

If you take no action during the grace period, your CD will automatically renew for another three-month term at OMB Bank’s 3-month board rate then in effect. That rate may be higher or lower than the promotional rate available when you originally opened the CD. OMB Bank will send you advance notice with information about your upcoming maturity and renewal options.
