U.S. Treasury and Federal Reserve Intervene to Prop Up Japanese Yen from Multi-Decade Lows

The United States Treasury and the Federal Reserve intervened directly in global foreign exchange markets to support the Japanese yen, executing outright purchases to rescue the currency from near 40-year lows. The rare coordinated intervention—facilitated through major Wall Street financial institutions—delivered one of the sharpest single-day rebounds for the yen in decades, stabilizing it near 157.40 against the U.S. dollar by the close of New York trading. U.S. Treasury Secretary Scott Bessent and Japanese Finance Minister Satsuki Katayama spearheaded the policy shift, acting to curb extreme currency depreciation that has squeezed businesses and stoked global import inflation. Financial markets reacted intensely to the sudden policy maneuver, which marks the first time in over a decade that Washington has actively intervened to bolster the Japanese currency. Currency traders and macroeconomic analysts are reassessing international intervention risks as central banks grapple with spillover effects from volatile global energy prices and shifting trade policies.
