US and Japan Confirm Rare Joint Intervention to Rescue Collapsing Yen

Japan and the United States confirmed a rare coordinated currency intervention on Monday, August 3, 2026, stepping in together to halt the Japanese yen's sharp slide toward 40-year lows. Japanese Finance Minister Satsuki Katayama formally announced the joint operation during a press briefing in Tokyo, stating that both governments executed coordinated yen-buying measures to counter excessive volatility and disorderly market movements. The intervention marks the first joint U.S.-Japan currency operation since 2011. The emergency action followed weeks of intense selling pressure that pushed the yen close to 164 per dollar last week—its weakest level since 1986. Bank of Japan data indicated that Japanese authorities spent approximately $58.97 billion during New York trading hours to support the currency prior to the official joint confirmation. U.S. President Donald Trump publicly acknowledged Washington's involvement on Sunday, telling reporters that the United States assisted to support a key economic ally. U.S. Treasury Secretary Scott Bessent backed the operation, confirming that Washington participated directly and would remain prepared to engage in further joint actions if required. Market response was immediate. Following the announcement, the yen surged past the 155 mark against the dollar, touching its highest level in three months. The U.S. dollar dropped roughly 0.6 percent to an intraday low of 156.50 yen during Asian trading hours as speculators rushed to unwind heavy short positions. The Bank of Japan maintained its benchmark interest rate unchanged at its policy meeting concluding late last week, though Governor Kazuo Ueda emphasized ongoing upside risks to inflation. Currency strategists noted that while the coordinated intervention successfully established a firm ceiling against further rapid depreciation, the long-term trajectory of the currency will continue to depend on upcoming U.S. employment data and future interest rate differentials betwee
