U.S. Treasury Intervenes in Currency Market to Support Japanese Yen for First Time in Over a Decade

The U.S. Treasury reportedly intervened in the currency market on Friday, July 31, 2026, to bolster the Japanese yen, marking the first coordinated action with Tokyo to support Japan's currency in more than a decade. The Federal Reserve Bank of New York executed a sale of euros to purchase yen on behalf of the Treasury. This move comes as the yen has been languishing near 40-year lows.
