I know, there are lots of threads out there, but it looks like there's somewhat inconsistent information that's offered as an aside.

Quick question. EE bond rate is almost 4% right now. People seem to think that the rate will decrease come Nov. 1. If I buy EE bonds before end of October and get an Oct. issue date, would I lock in the approx. 4% rate for 6 months or would it just change to the then-current rate on Nov. 1st?

For I bonds, I believe that if I were to buy I bonds before Nov. 1 and get an Oct. issue date, I would at least lock in the fixed portion of the interest rate for 6 months/life? with the variable rate to flucuate to the then-current Nov. 1st rate.

Am I interpreting this right?
