Japan Warns Yen Markets of Intervention After Joint Warning with Washington

Japan's policymakers are signaling their readiness to curb further declines in the yen after a joint warning from Tokyo and Washington. Atsushi Mimura, Japan's top foreign exchange official, urged markets to heed the 'very clear' message issued last week by Japanese and U.S. officials.

Mimura was speaking after Finance Minister Satsuki Katayama revealed that U.S. President Donald Trump had directly raised concerns about yen weakness during a summit with Prime Minister Sanae Takaichi.

The latest comments from Mimura and Katayama heighten investor focus on intervention risk, as officials underscore their unease over ongoing yen declines.
