I Bond yields will likely rebound come November

Tom Adams opined, following this morning's CPI report that Inflation-linked Savings Bonds, known as I Bonds will be bouncing back from their current 2.41% rate to yield somewhere in the neighborhood of 5 or 6% come the November adjustment.
This morning's CPI release for August showed inflation up 3.8% from a year ago. We now have CPI data for five of the six months between March and September that will be used to calculate the next I bond inflation component, which will likely end up somewhere between 4% and 5%.
Add that to the fixed base-rate of your own I bonds to determine what rate you'll get for the next six-month rate period. New I bonds will likely have a fixed base rate in the 1.0% to 1.4% range, for a composite rate that's most likely somewhere in the 5% to 6% range.
