The U.S. Treasury and Japan's Finance Ministry conducted a coordinated yen-buying intervention on Friday, July 31, 2024, to stabilize the Japanese currency [1].
This joint action marks a rare alignment between the two largest economies to prevent extreme currency volatility. Because the yen had slid to a 40-year low against the dollar [1], the sudden drop threatened economic stability and increased the cost of imports for Japan [3].
The intervention targeted the USD/JPY pair in the foreign-exchange market [2]. According to Bank of Japan data, Tokyo may have sold nearly $59 billion in U.S. dollars to support the yen [5]. This massive sale of dollar reserves allows the Japanese government to buy back its own currency, thereby increasing demand and boosting its value.
Reports vary on the historical precedent of this coordination. Some sources said this was the first coordinated intervention since 2011 [1], while other reports said it is the first joint action in 28 years [2] or the first time since 1998 [3].
The move signals a readiness for further action if the currency continues to slide. The coordination between the U.S. and Japan is intended to send a strong signal to speculators that the two nations will not tolerate excessive volatility in the exchange rate [3].
“The yen had slid to a 40-year low against the dollar”
Coordinated interventions are high-stakes tools used when a single nation's efforts are insufficient to stop a currency crash. By involving the U.S. Treasury, Japan leverages the global influence of the dollar to create a more powerful psychological and financial deterrent against currency speculators. The discrepancy in reporting regarding the date of the last single-joint action suggests a complex history of different types of interventions, but the current scale indicates a critical level of concern over the yen's devaluation.
