I have a CD in a 401k, and I just found out the CDs have to be brokerage CDs with a CUSIP number to be in the 401k. In comparing rates, the rates are much better for "normal" CDs than for CDs with a CUSIP. For example, 1 yr CDs on this site have 12-month rates that go up to 1.31% and include others in the 1.2% range, including IRA CDs. On Fidelity's site, the highest rate for a 12-month brokerage CD is 0.50%, and Fidelity said to be in the 401k, the CD must have a CUSIP.
Thank you!
