Banks didn’t increase rates despite inflation taking off. I’m sure I’m not alone, but I’ve put a lot of money in T-Bills through Treasury Direct. 1 to 6 months bills are now all yielding over 5%. My USAA deposit rate is still 0.01%. Be a moron to keep anything there, these banks did it to themselves.
If I wasn't concerned about staying mobile I would be tempted to acquire some fully depreciated and chip-free farm equipment. That's going to at least hold its value.
