Japan and the United States launch first joint yen-buying operation in 15 years

Japan's finance minister confirmed a coordinated yen-buying intervention with the United States, the first joint action since 2011, and said both countries stand ready to act again if needed.

On Friday, Japan and the United States executed a coordinated purchase of Japanese yen, marking the first such joint intervention since the 2011 earthquake response. Finance Minister Satsuki Katayama said the action was taken under the framework of a September 2025 joint statement to address the yen's sharp decline to a 40-year low of 163.99 per dollar. The intervention occurred during New York market hours and was intended to counter recent disorderly movements in the currency.

President Donald Trump confirmed that Washington acted at the request of Prime Minister Sanae Takaichi's administration, noting economic benefits for the United States. Treasury Secretary Scott Bessent posted on social media that the United States would not hesitate to repeat joint measures and praised Japan's steps to correct the yen's undervaluation. Both sides emphasized that the coordination ties Japan's economic security to its alliance with the United States, and they remain prepared for further action if market conditions warrant.

Why it matters

The joint yen intervention signals a rare, high-level coordination to stabilize a major currency and could affect global markets.

The left emphasises

  • analysts say the move aims to contain a sell-off that is raising import costs and inflation
