When asked why the United States intervened to support the Japanese currency, U.S. President Donald Trump told reporters aboard Air Force One over the weekend that the U.S. is “always there” for Japan.
“They have a weakening yen, and they wanted a little bit of help,” he said. When questioned over what the U.S. is “getting out of that arrangement,” Trump replied “financial benefit,” but emphasized it’s also “good for the world economy.”
The intervention follows an agreement reached in September 2025, when the finance ministers of both countries said joint action should be reserved for periods of “excess volatility and disorderly movements.”
Japan had already expressed “serious concern” over the yen’s rapid depreciation in March and conducted unilateral intervention between April 28 and May 27.
Despite those efforts, the currency continued to weaken, with the yen sliding to 163.73 per dollar on Thursday before rebounding to 157.57 on Friday.
