i bonds offer rates that are adjusted to protect from inflation. E e bonds do offer a guaranteed return hat doubles your investment if held for 20 years. But there's no guarantee with eyebonds. If inflation goes down, the eyebonds are also going down. i find ie bonds a lot more attractive than ee bonds because of the inflation protection component. When times like this come along, where inflationis really high, you get this huge bonus out of the eye bonds, and you don't get that out of the e bonds.
