Summary

US, Japan Intervene

U.S. and Japan coordinated an intervention that lifted the yen to below ¥157 in August 2026.
Intervention began July 31, 2026, when U.S. Treasury sold euros for yen and Japan bought yen.
Officials said aimed to stop a yen plunge that could force Japan to sell $1.114 trillion of U.S. Treasuries.
Analysts warned rise may be temporary because Japan’s 1.0 % rate lags U.S. rates and yen could fall toward ¥170 by 2027.

Summary

Bessent Guarantees Yen

Treasury Secretary Scott Bessent told CNBC the United States (U.S.) will do “whatever it takes” to help Japan stabilize the yen for American taxpayers.
President Donald Trump said the U.S. is “always there for Japan” after the joint yen-buying, framing it as ally support.
Economist Joseph Foudy warned the intervention serves U.S. self-interest by narrowing the trade deficit and deterring Japan from selling U.S. Treasuries that could raise rates.

History

Historical Context

The 1985 Plaza Accord, signed on 22 September by U.S. Treasury Secretary James Baker and German Chancellor Helmut Kohl, forced the dollar to fall and lifted the yen from roughly ¥240 to ¥160—a 33 % appreciation. The 2026 Treasury-led yen-buying program echoes that precedent, using euro sales to curb a yen plunge that threatens $1.114 trillion of U.S. holdings.
