U.S. Treasury Secretary Scott Bessent stated that his coordination with Japanese officials provides him with insight into the Bank of Japan's policy decisions. Speaking at Southern Methodist University, Bessent challenged market participants to bet against his efforts to strengthen the yen, asserting his direct role in currency policy.

Bessent is working with Japan's finance minister, Satsuki Katayama, on currency intervention strategies and has advocated for the Bank of Japan to increase interest rates. Sources suggest the central bank may implement a 0.25 percentage point rate hike during its meeting on September 18.

The yen has recently strengthened against the dollar, trading near ¥150. Hedge funds are positioning for the pair to drop below ¥150 by the end of the year, with some options targeting ¥140. The currency pair traded near ¥153.6 on Wednesday, down from levels above ¥155.

Japan spent $96.4 billion between July 30 and August 26 to support the yen after it reached a four-decade low. The U.S. also participated in these purchases. Additionally, Bessent has expanded a Treasury buyback program for older government securities to stabilize the bond market.
