With Ally Bank's 10-Day Best Rate Guarantee, you automatically get the best rate we offer for your CD during the first 10 days, starting with your open or renewal date, if you fund your CD within that time. This guarantee does not apply to interest rate increases for the Raise Your Rate CD.
If your CD ladder includes our Raise Your Rate CD , you’ll have the opportunity to raise your rate once over the 2-year term or twice over the 4-year term, if our rates increase on those CDs.
