I bonds are government subsidized, so no. The closest thing would be TIPS, but they have guaranteed negative real returns.
Nothing exactly like it but TIPS are Treasury Inflation Protected Securities.
Probably best to buy them in a fund due to their complexities. Vanguard and Fidelity both have funds for them.
They are lagging or get less of a return. The TIPS I have are yielding 6.25% right now. Still a fine place to park if you think the market might dump more or go sideways. Just pay attention to when the dividend pays and don’t sell before that
Thanks for the extra details! What do you think of buying a TIPS fund instead of purchasing TIPS directly?
Yes. There are TIPS, which are like I-bonds in that their yield is indexed to inflation, but unlike I-bonds in that you can't buy them at an artificially low price.
