United States Joins Japan in Rare Currency Market Action to Boost Yen
Washington, Sunday, 2 August 2026.
In a historic coordinated move on July 31, 2026, the U.S. Treasury directly purchased Japanese yen by selling euros, marking its first joint intervention to support Tokyo’s battered currency since 2011.
Execution of Coordinated Currency Purchases
The Federal Reserve Bank of New York executed the transactions on behalf of the Treasury, utilizing Goldman Sachs Group Inc and Morgan Stanley to conduct the trades [1][6]. This operational structure mirrors previous interventions where the New York Fed acts as the Treasury’s agent in financial markets [2]. Earlier in the day, the Treasury had informed several major banks to stand ready for future action, signaling a preparedness that extended beyond routine market monitoring [4]. The coordinated effort followed apparent intervention by Japanese authorities on Thursday, marking a significant escalation in attempts to support the yen [1]. Officials sought to curb the currency’s slide, which had increased Japan’s import costs and added to inflationary pressures [1]. The U.S. Treasury Department delivered the message to major banks via the New York Fed, with some institutions told to have executable trades ready to exchange Japanese yen for euros [2].
Market Reaction and Exchange Rate Shifts
Market participants responded swiftly to the reports of potential and actual intervention, driving the yen higher against the dollar during Friday’s session [4]. At the close of New York trading on Friday, the yen was quoted at 157.40 to the dollar, representing the strongest level since early May [5]. This recovery followed a period of significant weakness, where the currency had been flirting around the weakest levels since 1986 just two days prior [5]. On Thursday, the yen traded as low as 163.65 to the dollar before the intervention news took hold [4]. The movement from the Thursday low to the Friday close reflects a strengthening of the yen by approximately 3.819 percent [4][5]. Reports of possible U.S. intervention helped stabilize prices during Friday’s session, alleviating some immediate pressure on the currency [1].
Historical Precedent and Economic Impact
This coordinated action marks the first direct U.S. support for the yen since 2011, when G7 nations coordinated following the earthquake and tsunami disaster [6][7]. The rarity of such intervention underscores the severity of the yen’s decline and its ripple effects across global supply chains and financial stability [1]. A stronger yen can weigh on Japanese exporters by reducing the value of overseas earnings when converted into the domestic currency, yet it alleviates import costs for consumers [1]. Treasury Secretary Scott Bessent noted that the yen seemed very undervalued, indicating a shift in U.S. policy stance toward currency valuations [4][7]. Looking ahead, market observers are monitoring for potential joint policy announcements between Japan and the United States to address yen weakness in the coming week [6]. The U.S. Treasury maintains a strong relationship and close coordination with Japanese authorities, with further discussions expected at the G20 finance ministers meeting in Asheville, North Carolina, at the end of August [4].
