The Japanese yen has strengthened against the U.S. dollar, trading at around 154.41 yen per dollar, a decline of 0.65% from earlier levels. This movement follows comments from Bank of Japan Governor Kazuo Ueda, who emphasized that monetary policy decisions would be made on a meeting-by-meeting basis. The yen's appreciation is also attributed to speculation regarding a potential interest rate hike by the Bank of Japan in December. Concurrently, the dollar fell to session lows amid stock market declines and Ueda's remarks, contributing to the yen's gains.
