U.S., Japan confirm coordinated yen intervention, signal readiness for more

Japan and the United States have confirmed conducting a coordinated operation to buy yen, signaling their readiness for future interventions to maintain currency stability. This joint action follows a sharp fluctuation in the Japanese currency, which weakened to its weakest level in nearly four decades against the dollar. The finance ministries of both nations emphasized their commitment to close communication and readiness to act again if necessary.

The intervention, executed in accordance with a September 2025 joint statement, aimed to curb excessive volatility and disorderly movements in the yen. The Federal Reserve's foreign and international monetary authorities repo facility may be utilized in future instances. Treasury Secretary Scott Bessent affirmed the coordinated action, stating the U.S. remains attentive and ready to participate in future joint interventions.

President Donald Trump, in comments aboard Air Force One, expressed U.S. support for Japan's market and monetary measures to correct the yen's undervaluation, emphasizing the strong friendship between the two allies. However, some analysts caution that the intervention might undermine confidence in the yen if funded with euros instead of dollars, potentially raising questions about U.S. intentions in the process.
