Tokyo-Washington Yen Intervention Sends Shockwaves Through Markets
Washington and Tokyo joined forces to intervene in the foreign exchange market, buying Japanese yen (JPY) in an unprecedented move. The coordinated action was a joint effort between the US Treasury and Japan's Finance Ministry, with the aim of countering excessive volatility and disorderly movements in the yen.
The intervention took place on August 2, 2026, when USD/JPY fell from near 164 to 157.40 at New York close, before strengthening further to about 155.20 on Monday morning Tokyo time after the official announcement.
Treasury Secretary Scott Bessent confirmed the action, stating that it countered disorderly yen movements and that the US would not hesitate to participate in further joint intervention. Finance Minister Satsuki Katayama also commented on the move, saying that it was a warning to speculators and that Tokyo would respond if the market kept producing moves they judged as disorderly.
The intervention is seen as a significant shift in policy credibility, with both governments willing to act together to support Japan's currency. The move also signals that Washington views yen weakness as a shared policy problem, not just a Japanese one.
