President Trump called the first coordinated US–Japan yen purchases in decades a “signal of friendship.” Treasury Secretary Bessent said the Trump administration will “deliver on commitments to trusted partners.” Analysts warn Washington’s intervention is unlikely to be free: they say support for the yen — lifted from near 40‑year lows — may be tied to US strategic aims including bolstering Prime Minister TAKAICHI amid weak polls, pressing Japan to follow through on a previously pledged $550bn investment package into the US and to yield more in trade talks.
