Hmm - counterpoint, I think the hilariously negative TIPS spreads (and commensurately low forward inflation) are mostly a side-effect of the oil price falling out of bed. (Happy to be proven wrong here though.) The really amazing thing to me is the entire UST curve trading richer than Fed Funds, which is just… wow.
I'm pretty sure the soaring U.S. Treasuries preceded the recent OPEC/Russia news and falling oil price, although the oil markets may have added another exclamation point to U.S. Treasury trends. Oil isn't as important to overall inflation as it once was, so I wouldn't overinterpret it, and I don't think bond markets are.
Actually, one interesting side effect of a crash in oil and gas prices could be Texas's electoral votes. Texas is getting purple-ish. Conventional wisdom suggests 2020 is a little too early for a blue Texas, but sometimes events overtake conventional wisdom.
For those unfortunate souls holding insurance products such as long running endowment plans, non-guaranteed annuities, and whole life insurance policies, I wonder how the insurance carriers' par funds are doing and how divorced from reality the carriers' marketing projections are.
