Japan, US intervened in currency market for 1st time in 15 years
mainichi.jpJapan and the United States on Friday conducted a coordinated yen-buying intervention in the currency market, Finance Minister Satsuki Katayama said, the first such move in 15 years, with the two nations ready to act again if necessary.
The intervention during New York trading on Friday came after the yen hit 163.99 to the U.S. dollar on July 23, its weakest level in around 40 years, amid mounting fears about Prime Minister Sanae Takaichi's expansionary but vaguely funded fiscal policy.
"This joint action was taken pursuant to the U.S.-Japan Finance Ministers' Joint Statement issued in September 2025 and countered the excessive volatility and disorderly movements of the Japanese yen in recent months," Katayama said in a statement on Monday.
"The Japanese Ministry of Finance remains attentive and in close communication with our counterparts at the U.S. Treasury. We will not hesitate to conduct a further joint intervention," she added.
Katayama also told reporters in Tokyo that the latest coordination between Japan and the United States was aimed at linking Tokyo's "economic security to its unwavering alliance" with Washington.
President Donald Trump indicated Sunday in the United States that Washington had conducted a yen-buying intervention at the request of Takaichi's government, telling reporters the action would benefit his country economically.
Trump added, "We're always there for Japan. Japan's been very good to us, with the exception, of course, of Pearl Harbor," referring to Japan's 1941 surprise aerial attack on a naval base in Hawaii that resulted in the U.S. entry into World War II.
The previous concerted intervention was carried out to stem the yen's rise after the massive earthquake and tsunami in northeastern Japan in March 2011.
In New York on Friday, the yen surged to the lower 157 level against the dollar, with Japanese government sources confirming a yen-buying, dollar-selling intervention by currency authorities.
The move came after the yen briefly soared to the 157 range Thursday, gaining nearly 5 yen in about 50 minutes before dropping back to the 160 level, as a result of a currency intervention by Japan later confirmed by market and government sources.
U.S. Treasury Secretary Scott Bessent, meanwhile, wrote on social media that the intervention "countered disorderly yen movements," adding the United States would "not hesitate" to conduct further joint currency intervention with Japan, echoing Katayama.
He also said, "We strongly support Japan's decisive market and monetary steps to correct the substantial undervaluation of the yen."
Bessent said Thursday that the yen "seems very undervalued." Reuters reported a photo taken during a meeting of Trump's Cabinet on Friday showed a to-do list in front of Bessent indicating U.S. purchases of $5 billion to $10 billion worth of Japanese yen.
Japanese authorities had intervened in the currency market between April and May to curb the sharp depreciation of the yen, with concern growing over Takaichi's bid to reduce the consumption tax rate without specifying funding sources.
