text: I wouldn't buy I-bonds at the moment.  Once you buy them, you can't sell them for at least a year.  You can do just as well (earn a rate equal to or better what you can earn on an I-bond) putting money into a six month or one year CD.  Or perhaps a money market fund (search around, you can earn 4.5% in a basic MMF as of now), which would pay a tad less than a one year CD, but presumably the rate will increase going forward as there is little reason to think the Fed is done raising rates.
