Japan Producer Prices Rise 0.7% Monthly in October as Annual Inflation Accelerates to 7.1%
Key Facts
Japan’s producer price index rose 0.7% month on month in October 2026, while its annual increase accelerated to 7.1% from 6.8% in September, according to preliminary figures released by the Bank of Japan. The monthly increase followed a 0.2% decline in the index in the previous month, reversing the direction of company-level price pressures. Excluding the additional summer electricity charges, the index rose 0.9% in October, exceeding the increase in the overall index. The bank’s data show that the rise was concentrated in energy and industrial materials, rather than reflecting a general account of goods and services costs. The figures come ahead of the monetary policy meeting scheduled for December, as the bank faces mixed signals from prices and domestic demand.
Petroleum and coal products made the largest listed contribution to the monthly increase, at 0.20 percentage points, according to the Bank of Japan’s breakdown. Chemical products and related products contributed 0.15 points, while electricity, gas and water added 0.15 percentage points. Iron and steel contributed 0.11 percentage points, with galvanized steel sheets, hot-rolled strips and steel-cutting products among the items contributing. Year on year, prices of petroleum and coal products rose 15.9% in October, while chemical products increased 15.5%. Electricity, gas and water prices also recorded an annual increase of 15.8%, highlighting continued rises in energy and industrial input costs.
In external trade, the import price index denominated in contract currency rose 2.3% month on month in October and 19.2% year on year, according to the Bank of Japan. Petroleum, coal and natural gas prices made the largest listed contribution to the index’s monthly increase, adding 1.62 percentage points. The listed items included crude oil, jet fuel and gasoline, placing energy at the forefront of recorded import cost pressures in this currency. Earlier, Reuters reported that the yen-denominated import price index rose 24.5% year on year in September, describing it as evidence of higher costs for imported raw materials amid a weaker currency. That figure relates to September and the yen-denominated index, while the October figures concern the contract-currency import index.
Producer price pressures contrast with weakness in household spending: Japan’s real household spending fell 6.8% year on year in September, marking its tenth consecutive monthly decline. Reuters quoted an official at the Ministry of Internal Affairs as saying that poor weather contributed to September’s spending drop. This trend offers a different signal from accelerating producer prices, with the picture combining falling household spending and rising energy and industrial material costs. Reuters previously reported that analysts saw a possible Bank of Japan rate hike in December and that spending data would be among the factors the bank scrutinizes when considering its decision. The report does not attribute that expectation solely to the producer price index, but presents it as part of the broader assessment followed by analysts and the bank.
In its latest outlook, issued in October, the Bank of Japan said consumer price inflation, excluding fresh food, was likely to accelerate to a level clearly above 2%. The bank attributed its forecast to oil prices, the pass-through of wage increases to prices, AI-related demand and the weaker yen. It also gave a range of 2.4% to 2.6% for core inflation in fiscal 2026, with a midpoint of 2.5%. In September, the consumer price index excluding fresh food rose 2.1% year on year, while the index excluding fresh food and energy increased 2.4%, according to Japan’s Statistics Bureau. The bank said in its report that it would continue raising interest rates and adjusting the degree of monetary easing, while taking economic, price and financial developments into account.
The Bank of Japan is scheduled to hold its next monetary policy meeting on December 17 and 18, 2026, according to the bank’s calendar. The meeting follows the release of September household spending data and October producer price data, both indicators used to track price and demand developments. Reuters quoted Governor Kazuo Ueda in October as saying that underlying inflation had “now come quite close to 2%,” and described the bank’s focus as keeping that inflation stable around that level. The December meeting reflects the bank’s continued assessment of the inflation path and the timing and pace of monetary policy adjustments. October’s data remain part of that assessment, alongside other spending and price indicators cited by the bank and analysts.
