Mimura Sees Joint Yen Intervention as Peak of US-Japan Currency Alliance
Japan's top currency diplomat, Atsushi Mimura, says the recent joint yen intervention was the culmination of a long-standing US-Japan currency alliance. This cooperation is seen as a sign of durable and structural cooperation between the two countries, which could support confidence in future coordinated action if the yen weakens again.
Mimura declined to comment on President Trump's remarks regarding foreign exchange intervention or the specifics of discussions with the Bank of Japan. However, he did confirm that Japan will continue to work closely with the BOJ, indicating continued coordination between currency and monetary policy.
The FIMA repo facility, a swap-line style tool, was flagged as an important backstop by US Treasury Secretary Scott Bessent. Mimura clarified that this facility is just one instrument among several available for intervention, and its funding limits do not constrain Japan's broader intervention capacity.
