Japan’s finance ministry and the U.S. Treasury have confirmed coordinated intervention to support the yen, with Japan suspected of deploying $58.97 billion in a single day to buy the currency. U.S. officials also signaled they could enter the market, and a photo showed Treasury Secretary Scott Bessent with a handwritten note reading, “Buy Japanese Yen (JPY) $5–10 bil.” Combined with the Bank of Japan’s June rate increase to a 31-year high of 1%, the steps provide tangible support for the yen. The move directly targets FX markets, with the yen and the dollar/yen pair at the center of the impact.
