TIPS have absolutely terrible rates now. “I-Bonds” are at over 7% interest right now. You’re allowed to put in $10k+5k / person / year (the extra $5k must be from a tax refund although I’m sure you can just overpay on purpose). Rates are locked in for 6 months and adjusted based on CPI after. They can’t go negative. There’s a minimum holding period of 1 year, and a few other minor pieces of fine print you should read up on. But if you want a safe high interest investment, this is currently WAY better than TIPS.

I read in the WSJ that manufacturers were purposely severely cutting down on different options to simplify their supply chains and make sure they don’t lose money, so your observation is accurate. Propane prices are going up due to the large increase in demand due to restrictions on indoor operations (so stuff like outdoor dining in the cold requiring a lot of propane to heat the area for customers).
