Ally Bank made a slight rate cut to its 5-year CD. It's now 3.10% APY (was 3.15%). If you applied before the change, you should still receive 3.15% thanks to the Ally Bank's 10-day rate guarantee for CDs. However, this guarantee doesn't help if you haven't submitted an application. According to the CSR:
The 10 day rate guarantee covers the 10 calendar days after the application is entered and accepted.
This 5-year CD is still a good deal thanks to Ally Bank's small 60-day early withdrawal penalty. Refer to my Ally Bank CD review
