Japan's currency authority spent a record 15.39 trillion yen ($96.5 billion) to support its currency between July 30 and Aug. 26, Ministry of Finance data showed Friday. This marks the largest amount spent in a single intervention round. The intervention underscores Tokyo's resolve to counter the yen's weakness, which has been near a 40-year low against the dollar. The Bank of Japan has signaled a willingness to tighten policy, with markets assigning a 65% chance of a rate hike in September. The yen strengthened from around 163 per dollar to as high as 155.20 by August 3, following the intervention, including a rare joint action with the U.S. on August 3. U.S. Treasury Secretary Scott Bessent affirmed support for Tokyo's efforts to stabilize the yen.
