Aboard Air Force One on Sunday, President Donald Trump told reporters that Washington had stepped in to help Japan's currency, describing it as one ally standing by another. "We're always there for Japan," he said, addressing why the U.S. had gotten involved. The remark came after Japan's finance ministry confirmed a rare, coordinated effort to halt the yen's slide to its weakest level in roughly 40 years, with Tokyo signaling it would act again if needed. Treasury Secretary Scott Bessent added his own confirmation, posting online that the U.S. was ready to take part in additional joint operations if conditions called for it, per Bloomberg.
