The United States is prepared to join additional coordinated foreign exchange intervention with Japan if excessive volatility in the yen continues, U.S. Treasury Secretary Scott Bessent said on Sunday, reinforcing Washington's support for stabilizing currency markets. In a post on X, Bessent said the joint U.S.-Japan intervention conducted on Friday successfully addressed what he described as "disorderly yen movements." "We will not hesitate to participate in further joint intervention," Bessent wrote. Japan recently confirmed that Friday's operation marked the first coordinated yen-buying intervention with the United States since 2011. Bessent further praised Japan's recent currency and monetary policy measures, arguing they address the yen's significant undervaluation.
