The dollar climbed into the low-158 yen range in Tokyo, with market participants identifying the month-to-date high of 160.39 as potential upside as expectations for additional U.S. rate hikes strengthened dollar demand. The yen remained near 158 per dollar on September 24 after the Bank of Japan raised its policy rate by 0.25 percentage point to 1.25% on September 18, as stronger U.S. activity data, higher Treasury yields, renewed inflation concerns and weak demand at a five-year Treasury auction supported the dollar. Japanese authorities conducted overseas foreign-exchange rate checks, and Finance Minister Satsuki Katayama said the principles behind coordinated Japan-U.S. intervention on July 31 remain in place if excessive volatility and disorderly market moves return. The yen’s approach toward 160 revived intervention concerns, although analysts said unilateral action might have limited durability without further BOJ tightening or U.S. support.
