US Treasury Rescues Yen with Rare Euro Intervention
The US Treasury executed an extraordinary foreign exchange intervention in July 2026 to prop up Japan's collapsing yen. Tokyo requested urgent assistance after the Japanese currency plummeted to its weakest valuation since 1986, with a value of 163 against the dollar.
To avoid destabilizing the domestic American bond market, the US Treasury utilized the Exchange Stabilization Fund (ESF), which holds approximately $13.1 billion in euro-denominated reserves. By selling euros through Goldman Sachs and Morgan Stanley, the US Treasury acquired yen without injecting excess dollars into the market.
The intervention successfully boosted the yen's value to around 155 against the dollar, with trading platforms experiencing unprecedented volatility. This operation marks a significant geopolitical pivot, underscoring the deepening economic alliance between Washington and Tokyo in the face of broader Asian economic instability.
