Someone may have bought 10 year 2% notes intending to hold to maturity because they thought inflation would stay at 1% and they just wanted to park cash. But with inflation at 3-5% they now need to dump and buy something else.
People change their tactics to achieve their strategy.
I highly doubt they are serious, but that's the interpretation I have if their POV.
Actually people who bought Treasuries in 2021 are almost underwater on it already, just in inflation these last two years. Cumulative price increases for 2021 + 2022 was 14.5%, while 10 years of 1.5% interest gives you 16%. Inflation would have to be basically zero for the next 8 years for them to break even.
