The United States and Japan have jointly intervened in currency markets to stabilize the Japanese yen, which had fallen to a 40-year low. This coordinated action marks the first such intervention by both countries since 2011, following a devastating earthquake and tsunami in Japan.
Both the U.S. Treasury Department and Japan's Finance Ministry have indicated a willingness to engage in future joint interventions if necessary. The move is intended to prevent a sell-off in the yen and Japanese government bonds from negatively impacting the global economy, including potentially increasing borrowing costs for the U.S.
The yen's weakness is largely attributed to Japan's significantly lower central bank interest rates compared to other major economies, such as the U.S. This disparity makes the Japanese currency less attractive to international investors. The Bank of Japan recently raised its key interest rate to 1% in June, its highest level since September 1995. In contrast, the U.S. Federal Reserve's benchmark rate remains between 3.50% and 3.75%.
Japan also faces long-term challenges including a declining working-age population, low productivity, and a substantial reliance on energy imports priced in U.S. dollars. These factors contribute to the yen's persistent weakness.
Japan's Finance Ministry stated that Friday's intervention, conducted with the U.S. Treasury, aimed to counter "excessive volatility and disorderly movements in the Japanese yen in recent months." U.S. Treasury Secretary Scott Bessent confirmed these coordinated foreign exchange actions addressed "disorderly yen movements" and expressed strong support for Japan's measures to correct the yen's "substantial undervaluation."
