The Bank of Japan’s most dovish members warned against a rush to raise its benchmark interest rate, saying authorities needed to closely monitor the impact of U.S. tariffs on economic activity. “Given the extremely high uncertainty, I think the central bank should conduct monetary policy cautiously to reflect the actual state of economic recovery,” Toyoaki Nakamura, a member of the central bank’s policy board, said in a speech in Fukuoka, southwestern Japan, on Friday. In his last scheduled speech before his five-year term ends next month, he stuck to his cautious stance; he had voted against rate hikes implemented by Bank of Japan Governor Kazuo Ueda since March last year.
