Update 6/28/2011: Ally is now offering IRAs. Please refer to this new Ally IRA post for more details.
A reader mentioned in an email that Ally Bank will soon be offering IRA CDs. I just checked with Ally Bank, and a customer service rep confirmed that this is true. According to the CSR, they expect to launch the IRA CDs before the end of the year. Unfortunately, he wasn't able to provide any details about the IRA CDs.
I asked if the savings account would also be an option in the IRA. He wasn't sure, but he said it didn't seem likely due to the nature of IRA accounts. You probably don't want to keep IRA funds in a savings account for a long period of time since it typically has a lower interest rate than CDs. However, a savings account is useful if you plan to move your funds to another institution since you don't have to worry about CD early withdrawal penalties. This may not be much of a concern at Ally Bank since Ally's CD early withdrawal penalty is only 60 days of interest (see post).
Discover Bank IRA Certificate of Deposit
Ally Bank's IRA may look like what Discover Bank offers. Discover Bank's IRA can only hold CDs. Discover does not offer a savings account in the IRA. To transfer the IRA funds to an IRA at another institution, you may want to wait for the CD grace period (up to 9 calendar days after the maturity date). Otherwise, Discover Bank will likely charge an early withdrawal penalty. I just confirmed this with the Discover Bank CSR this morning. If you have multiple CDs in your Discover Bank IRA with different maturity dates, transferring the IRA funds without an early withdrawal penalty can be complicated.
Note, I'm not considering any penalties by the IRS. You shouldn't have to worry about taxes or IRS penalties if you transfer or do a rollover from one institution IRA to another institution IRA.
PenFed IRA Certificates
Some institutions allow you to have a savings account in your IRA. This is common at credit unions. Pentagon Federal Credit Union is a good example. Its IRA savings account doesn't pay much interest, but it can be useful when your IRA CDs mature. When your IRA CDs mature, you can move those funds into the IRA savings account. Once in the IRA savings account, you can do an IRA transfer to an IRA at another institution without worrying about CD early withdrawal penalties.
Another nice feature regarding PenFed is that they do allow penalty-free partial withdrawals from your IRA CDs once you have reached 59½. I have more details on this feature in this post.
