I have a question about I-Bonds. I have one I-Bond at Treasury Direct and I check to see what its total value is on the first day of each month. I "assumed" it would increase by the same amount each month for 6 months and then reset each May and November. But I am not seeing that behavior. Here is what I've seen for the past 2 years. Can someone help me understand what I'm missing?
