USD/JPY

The confirmed US-Japan joint FX intervention — Washington's first yen-buying action with Tokyo in over a decade — changes the game: the 160.00 level is now a de-facto policy red line, and any rally toward it risks triggering further coordinated selling.

Joint US-Japan intervention has capped upside near the 158.00 psychological level, with coordinated yen-buying by the US Treasury and BoJ signalling a structural ceiling for USD/JPY in the near term.

Additional US-Japan Coordinated FX Intervention

With Japanese Finance Minister Katayama formally announcing joint intervention and the US Treasury already having sold yen through the NY Fed via Goldman Sachs and Morgan Stanley, the threat of repeat intervention between 158–160 makes short-USD/JPY the path of least resistance.
