Japan Finance Minister Taro Aso voiced caution about the merits of further stimulus by the Bank of Japan, saying that monetary policy alone could not achieve its 2% inflation target, NewsNow reported. Aso’s remarks came amid speculation that the BoJ may embark on a fresh round of quantitative easing at its policy meeting on Oct. 30 in a bid to nudge inflation up toward the target next year. “There’s limit to what monetary policy can do to boost prices,” Aso told reporters on Friday after a cabinet meeting. “In the current situation, it is hard to hit the original aim with the BOJ’s monetary easing alone.”
