The United States and Japan conducted a rare joint intervention in currency markets on Friday to prop up the yen, marking their first coordinated action since 2011, according to officials in Tokyo and Washington. The yen had slumped to a 40-year low against the dollar, reaching nearly 164 yen per dollar before the intervention, which reduced the rate to about 157 yen per dollar by Monday.
Japanese Finance Minister Satsuki Katayama confirmed the joint action, stating it aimed to counter “excessive volatility and disorderly movements” in the yen. She added that Tokyo would not hesitate to conduct further interventions if needed, emphasizing close coordination with the U.S. Treasury Department .
The Bank of Japan’s data suggested its purchases alone may have totaled $36.58 billion during the operation, while reports from The Wall Street Journal estimated the combined intervention at $60 to $80 billion, with Japan contributing the majority . A leaked handwritten note from U.S. Treasury Secretary Scott Bessent indicated a planned purchase of $5 to $10 billion in yen .
Former U.S. President Donald Trump stated on Sunday that Washington’s support for the yen was a gesture of friendship and a contribution to the global economy . Japan’s top currency official described the joint intervention as the culmination of the U.S.-Japan alliance.
Analysts noted the U.S. took an unusual approach by selling euros rather than dollars to buy yen, a move that surprised currency markets . The yen’s prolonged weakness persisted despite recent interest rate hikes by the Bank of Japan, which set its benchmark rate at 1%, far below the U.S. Federal Reserve’s range of 3.50% to 3.75%.
Gunter Deuber, chief economist at Raiffeisen Research, said the coordinated action sent a deliberate signal, as joint interventions tend to have a stronger effect . The Japanese Ministry of Finance reiterated its readiness for further measures, stating it would act again if market conditions warranted.
