Will probably keep my I-bonds until all other "cash-like" accounts are used up. I like that you can cash them in and have say 1/2 taxable, 1/2 non-taxable, depending upon the interest accrued. This allows you to "titrate" your taxable income in a given year - i.e., cash in enough to just keep yourself within a certain tax bracket, but actually end up with more cash than the taxable portion. Wish I had taken out more of these when it was a good deal, interest wise. Too late to the party, that's me!
Seriously considering transferring some of my more cash-like (AKA old SPDAs paying a guaranteed 4.5%) Trad. IRAs to VG TIPS fund, but I've got more research to do on that. What do others think about TIPS funds (especially of the VG persuasion?)
My other inflation hedge will be to purchase more equities as I re-characterize Trad. IRAs to Roths. The theory I always hear is that equities (though with a stormy ride) outpace inflation in the long run. At almost 62, not sure I have a long run in store, but... Don't know if this is a good move or not. Ask me in 20 years.
RE: The dollar: Need to do more research into unhedged OUS funds. I'm very weak on this sort of thing.
Now that they (and everything else is beaten down) might be a time to dip a toe into the water. We'll see.
Probably, you should watch what I do and then do the opposite, 'cause YMMV, heh, heh.
