What if you have 10 or 20 years old I bonds ?

Is this rate only for newly purchased bonds ?

The rate on any I bond is the sum of the base rate (fixed at time of purchase) plus the current “official” rate of inflation.

So I bonds bought at different times would have different rates today, due to what the base rate was when they were purchased.
