President Donald Trump said the United States intervened in the foreign-exchange market on Sunday, Aug. 2, to support the Japanese yen.
This move represents a rare coordinated effort between two of the world's largest economies to stabilize currency volatility. Such interventions are typically used to prevent rapid currency devaluation that can disrupt international trade and domestic pricing.
Trump said the action was a "signal of friendship" and noted that the U.S. is able to assist Japan because of the strength of the American dollar and economy [1]. He said the United States is backing the yen to benefit the global economy [3].
Prior to the intervention, the yen had fallen to a 40-year low against the dollar [4]. Following the joint action, the U.S. dollar weakened sharply against the yen [5].
This operation marks the first joint U.S.-Japan currency intervention in 15 years [4]. The coordination involved the U.S. and Japan's finance minister to address the currency imbalance.
"We're always there for Japan," Trump said after confirming the joint support for the yen [2].
“"It's a signal of friendship,"”
The decision to intervene in the currency market suggests a shift toward active management of the yen's value to prevent economic instability in Japan. By coordinating the effort, the U.S. aims to leverage its economic position to support a key strategic ally while attempting to maintain global market equilibrium.
