I wonder if these will come in TIPS versions. We had quite substantial inflation in 1919, 14-18%, followed by massive deflation in 1921 approaching -16%, and +9-15% in 1980/1981. Looking at the past 25 years, you might get the idea it's not a good idea to buy TIPS bonds, but is hyperinflation inevitable or is it a solved problem?
