Commerzbank warns FX interventions alone are insufficient to stabilize the JPY without further Bank of Japan tightening.
Japanese authorities cannot rely solely on FX interventions to support the yen against the USD, according to analysis. Past interventions yielded mixed results, with July 2024’s success tied to a Bank of Japan rate hike.
The BoJ’s second rate increase in late July coincided with a rare effective intervention, reinforcing the view that monetary policy backing is critical. USD/JPY levels above 160 have triggered interventions, but warnings from the Ministry of Finance often precede action.
Commerzbank forecasts two additional BoJ hikes and expects USD/JPY to decline through 2026. Without further tightening, the yen’s outlook remains under pressure.
