From what Gumby posted in the IBond thread, it looks like IBond rate inflation components will drop significantly to 2% or so for the next reset in May 2023, in which case the IBond train will be derailed for me. I'll stick with IBonds as long as their yields are competitive with 2-5 year US Treasuries.
If the IBond train does derail I'll likely transfer the money to my taxable brokerage account and invest in 2-5 year CDs/USTs/GSEs.
One unintended consequence is when I do cash out that the interest income recognized will reduce my Roth conversions for the year dollar-for-dollar.
I am also in process of simiplfying the number of accounts that I have for estate administration reasons. I got rid of most credit union CDs in 2022, one to go in 2023.
If the I-Bond money in 5 different accounts (2 individual and 3 trusts) gets moved to a single joint taxable brokerage account over 2023-2025, I could end up with as few as 5 accounts (taxable joint, his tIRA, his Roth, his HSA, her HSA) by the beginning of 2025. DW has a small $$$ Roth credit union CD (4.5% of total retirement assets) maturing in early 2023 that I need to decide whether it is worth keeping and rolling into a Roth brokerage account or just withdrawing and having one less account to deal with. I'll probably keep it in the Roth.
By contrast at the beginning of 2022, we had 17 financial accounts and added 3 in 2022 so we had 20 before the purge started... so getting down to 5 or 6 accounts with 2 different brokerage houses will greatly simplify our finances and the administration of the estate for DW and DD if I get hit by a beer truck.
