Japan has announced a joint venture with the United States to conduct a yen-buying intervention that will counter the yen's fall in value.

Initiation of the first joint intervention between US and Japan since 2011 begins as Japan's finance ministry announced the venture, explaining that the plan was to counter "excessive volatility and disorderly movements in the Japanese yen". He also assured that if the issue is not resolved, they will plan for further joint ventures.

Bessent indicated in a social media posting on X that the Fed's Foreign and International Monetary Authorities lending facility was used in the coordinated action on Friday, which was confirmed by Japan's finance ministry and President Donald Trump.

The loans are offered at a rate typically above the open-market repo rate, so the expectation is that its use would be limited to times of market stress.
The Japanese yen had hit 163.73 against the greenback on Thursday last week, and strengthened to 157.57 on Friday. It was trading at 157.70 per dollar on Monday. The yen’s weakness has become an increasing concern for Tokyo, with the currency recently falling to its lowest level in roughly four decades against the dollar.
“In accordance with the ‘Joint Statement of the Japanese and U.S. Finance Ministers’” issued in September 2025 and was aimed at addressing “the recent excessive volatility and disorderly movements of the yen.” Says ministry officials.
The U.S. had participated in last week’s coordinated intervention to help the yen as a gesture of support for Japan and in the interest of global economic stability.

If Washington sold euros instead of dollars to buy yen, investors may infer U.S. officials were trying to spare Japan from selling U.S. Treasury to finance intervention, he added.
