Yes. I don't think anyone knows for sure - like 7.12% seemed amazing at the time but we didn't expect an oil shock or a war in europe.
Bear in mind there are some other technicalities with i-bonds. They are all documented on the treasury direct website:
- you have to hold it for a minimum of 12 months
- there are two parts of the bond a fixed rate (currently 0%) which is set for the lifetime of the bond, and the variable rate which is tried to inflation
- if you hold it for less than 5 years when you withdraw there will be a 3mo interest penalty
- you're limited to 10k purchased per SSN, you can get over 10k if you get your tax refund in i-bonds.
