This.

I've loaded a bunch of my savings into IBonds last year and this year. 7-9% interest rates during that time.

Obviously, not the same as HY savings account where you can pull the money out for whatever at any time, and still different from a CD where it is locked up for however long since IBonds have a penalty of losing 3 months interest on any funds you withdraw before 5 years. But, if you don't need that kind of liquidity (if you are looking at CDs, you probably don't) and you can keep the bonds for more than a year before cashing out, even now as the IBonds interest rate is going down, you probably would come out ahead of the current 2-3% rates on CDs.
