The yen saw a dramatic rebound, strengthening to the lower 155 range against the dollar on Monday morning, August 3, 2026. This follows a joint yen-buying intervention by Japan and the U.S. that caused the currency to rise by 1% in the Asian morning to an intraday high of 156.01 per US dollar.
This surge comes after the yen had previously breached 161.95, reaching a 40-year low against the US dollar. Authorities had already spent an estimated $70 billion this year to support the currency. The intervention, confirmed by Japan's finance ministry, involved Japan potentially buying as much as $58.97 billion worth of yen on Thursday, prior to the Monday rally.
Analysts like Elias Haddad, global head of markets strategy at BBH, noted that "joint FX intervention packs a punch, and investors should lean with the official flow, not against it." Goldman Sachs analysts suggested that encouraging repatriation could be a powerful policy for long-term currency influence. Markets remain on high alert for further interventions, especially if the yen begins to weaken again, as past coordinated US FX interventions have historically been successful. The yen's weakness has been attributed to the Bank of Japan's gradual approach to monetary policy tightening, maintaining wide yield differentials with other global economies.
