Japan's core CPI annual growth rate for September 2026 (Q3) rose to 2.1%, which not only met market expectations but also expanded significantly compared to the previous reading of 1.7%, breaking above the Bank of Japan's 2% inflation target for the first time in nine months. Driven by a weak yen and rising energy costs, the "core-core CPI" excluding energy also accelerated, and service prices further reflected the pass-through effect of wage costs. As underlying inflation pressures spread, market expectations for a further interest rate hike by the Bank of Japan before the end of the year have risen sharply.
