Japan steps in to save the yen
Suspected intervention after data
Tokyo’s currency authorities executed another aggressive foreign exchange intervention on 11 July, stepping in immediately following the release of softer-than-expected US consumer price inflation. Taking advantage of dollar weakness, the Ministry of Finance deployed billions in reserves, driving the yen from a thirty-eight-year low of 161.9 back toward 157 per dollar.
The Counter-Cyclical Squeeze
By timing intervention to coincide with a macro data surprise, Japanese authorities maximized the pain inflicted on levered short-yen momentum traders. Yet tactical intervention cannot cure a structural ailment. So long as the Bank of Japan maintains near-zero borrowing costs while global yields sit comfortably higher, Tokyo is merely leasing temporary relief at immense reserve cost.
Tokyo’s tactical yen intervention inflicted sharp losses on speculators, but burning foreign reserves cannot substitute for authentic domestic monetary tightening.
