Good point. Though right now you also get the current 9.62% for 6 months so you come out ahead still with most likely an 8% return over 1 year. After November, it'll be interesting to see if I Bonds are worth buying anymore or if treasury bonds go down. It's also possible that in November they add something more than 0 to the fixed rate of the I Bond. Buying now though you unfortunately would not get that.
