Japan's Producer Price Index (PPI) for October 2026 grew by 0.7% month-on-month, sharply reversing the previous -0.3% decline and far exceeding market expectations. This surge reflects the weak yen and climbing import costs, with price pressures broadening from energy into diverse sectors such as chemicals and steel. The robust upstream inflation data further cements the market consensus that the Bank of Japan will tighten monetary policy again by the end of the year.
