I have written about Ally Bank before, and I have been their customer for years. I have an Online Savings account that currently pays 1.15% APY. This is a decent return for a day-to-day account.
I have also had 2- and 4-year Raise Your Rate CDs that both offer 1.5% APY. This 11-month CD matches the yield on the longer term CDs, but it doesn't have an early withdrawal penalty.
The main risk of a long-term CDs is the chance that interest rates will rise and you’re committed to the lower rate until the CD matures. But with no early withdrawal penalty, if rates rise there is no risk. You can withdraw the money with no penalty, and then put it back into a new CD at the higher interest rate.
