Japan Readies for Yen Intervention Amid Rate Hike Expectations

Japan's top currency diplomat Atsushi Mimura has warned against excessive yen declines, signaling that Tokyo is ready to intervene in the market. This warning comes despite the yen's 2% jump against the US dollar on September 3.

Mimura stated that there is no change to Japan's stance of being on alert to currency moves and that they remain in constant contact with US authorities after the G-20 finance leaders' gathering in Asheville, North Carolina. The US dollar fell to 155.305 yen following Mimura's comments, but soon gave up its gains and fell to 156.43 per US dollar later in Asia.

Markets have nearly fully priced in the chance of a Bank of Japan (BOJ) rate hike in September after a series of hawkish BOJ communications and comments from US Treasury Secretary Scott Bessent urging the Japanese central bank to raise rates. However, Finance Minister Satsuki Katayama clarified that she had not received any demands from Bessent over Japan's monetary policy.
