Long-duration nominal sovereign bonds are not a reliable hedge in this regime: the two post-1980 tailwinds (declining real rates, demographic bid) are both reversed. As of Sept 2026 the fiscal stress is priced through the term premium, not through repression (30y auction 5.308% on 2026-09-10, highest since 2001; 30y TIPS ~3%; Fed hiked 12-0 on 2026-09-16), so long nominals lose in price; the 1939-1979 financial-repression analogue (positive nominal, deeply negative real returns by policy design) is a possible later-stage response, not the present condition. 30y USTs returned ~-4%/yr nominal and ~-7.5%/yr real over 2020-2025. At 5%+ starting yields the deflation-tail case for some duration is stronger than in 2020-21, so the claim rests on the regime argument, not the starting yield. Japan is the completed test case.
