Sun Federal Credit Union is offering a 5.33% APY 54-month certificate (see rate table). The minimum deposit for this yield is $75K. This is also availabe as an IRA certficate. A yield of 5.11% APY is available on the regular CD for a $1,000 minimum.
This 54-month certificate has a Raise-Up feature that allows a one-time rate bump during the term to match the current rate. With falling rates, I doubt this will be useful, at least for the next year.
I called the credit union today, and I was told that this rate is still available. The CSR didn't know when the rate would change.
