With a Rising Bank CD you can put a floor under your yield for up to $0.5M of your money for three years. It’s a $25K buy in so quite steep. And the yield is only 2.5% APY. But it’s an add-on and it’s not GTE:
Note: Rate is not high to begin with and has been falling. If you want it, better move quickly.
Q: Shin, are you in?
Not at this time. With a lower buy in, even a few thousand, this would be a no-brainer in the current interest rate environment. But with price of entry at $25K, well, not for me so far. It’s one of those CDs I’ll probably wish I had in a couple of years when my add-on deal at GTE collapses. 
Q: Huh? Collapses?
I did USCU way back, and Valor more recently. Enough said.
