Ptf. I am at work so I can't check the math but am confused.
If the I bond rates are at 7.12% now for April and I buy by the end of the month, I can't assume that the variable rate at 6 months will be more than 0% in a worst case scenario correct? I don't really see how the May CPI factors into a guaranteed return or why you are averaging April and may.
But then again, I'm not an i Bond expert and have largely avoided this topic. Maybe I need a refresher on how these work.
Your bonds are set to the most recent rate, issued in May or November, every 6 months.
Any bonds bought this month (April 2022) will get the November 2021 rate. In October 2022, they'll be set to the May 2022 rate.
Bond A bought this month: 7.12% April through Sept
Bond A: 9.62% Oct 2022 through March 2023
Bond B bought in May 2022: 9.62% May 2022 through Oct 2022
Bond B: ??.?% Nov 2022 through April 2023
Will inflation be higher this summer and into the fall, in which case you should wait until May to buy? Or will it go down because most of the increase was due to gas prices*?
