Japan’s core inflation climbed to 2.1% in September, up from 1.7% in August, moving back above the Bank of Japan’s 2% target. It was the first time this year that the country’s key price gauge had exceeded that level. Higher food and energy costs, along with a weak yen, contributed to the renewed price pressure. The increase has strengthened expectations that the central bank will raise interest rates again. The BOJ was expected to leave rates unchanged at its October meeting, even as policymakers weigh another increase. The latest inflation reading adds support to expectations of a rate hike in December. Investors will be watching the bank’s decisions for signs of how it plans to respond to prices remaining above its target.
