Japan's 10-year JGB crosses 3% for the first time since 1996, and the US Treasury Secretary publicly presses Tokyo to hike

What happened

Japan's 10-year government bond yield crossed 3% on 09-01, its first time above that line since 1996, while US Treasury Secretary Scott Bessent went on CNBC to press Tokyo and the Bank of Japan publicly for rate hikes. Reporting on the exchange flagged the specific transmission risk: Japan is the largest foreign holder of US Treasurys, and a yen-defence intervention funded by selling them would push US long-end yields the same direction this thread already tracks domestically. This is the escalation of the cross-border leg this thread first recorded on 08-19, when a JGB push toward its highest yield since 1996 took SoftBank, Kioxia, Arm and Tokyo Electron down together in one Tokyo session — the mechanism is the same, the yield has now actually crossed, and a US cabinet officer is now an actor in it rather than an observer. attention/capital-context.yaml has twice flagged its own reading as "almost entirely US-Fed-framed" with a proper BOJ/JGB leg deferred to a /week-scale addition; this is that deferral coming due.
