Statistics Norway (SSB) released the September results of its producer price index (PPI) on 9 October. The index tracks prices for goods produced in Norway and sold in the domestic or export market. It rose 12.4% from August and 48.8% from September 2025. With 2021 set to 100 as the reference year, the September index level was 166.7. The series measures first-hand selling prices by producers; it is not a consumer price measure and does not by itself show that retail prices will move in the same direction or by the same amount.

The energy goods index increased 20.4% in the month and 90.1% over the year. The PPI excluding energy goods rose 0.5% monthly and 6.7% annually. The contrast shows how a large movement in the energy component can make the total index differ substantially from the measure excluding energy. In SSB’s weight table, energy goods accounted for 496.0 of the total 1,000.0 weight, while goods excluding energy accounted for 504.0. Weights describe the composition of the index; they are not a direct representation of company expenditure or household budgets.

The total domestic-market producer price index rose 2.5% from August to September, while the export-market index increased 17.7%. Over 12 months, the change was 15.9% for domestic sales and 70.4% for exports. The gap reflects differences across markets and product groups, not a single uniform price movement. SSB reports separate industry series for extraction of oil and gas, manufacturing, mining, and electricity, gas and steam supply. The aggregate should not be read as the performance of any one industry.

Among selected manufacturing categories, food products rose 1.6% in the month and 8.9% over the year. Refined petroleum products increased 4.0% monthly and 47.0% annually; basic metals rose 0.3% and 17.0%, respectively. Machinery and equipment increased 0.4% monthly and 4.6% annually. These differences show why the industrial scope matters when interpreting the headline. The aggregate combines categories whose prices can move at very different rates.

SSB calculates the PPI from product prices collected through surveys and weights updated annually. Its methodological notes say some missing price observations may be imputed using movements at a higher index level; the index is not seasonally adjusted. The monthly rate should therefore not be presented as a growth measure adjusted for seasonal or calendar effects. The PPI is used in national accounts and short-term economic monitoring, among other applications, but the figures reported here do not by themselves explain the cause of inflation.

SSB explains that the PPI and the price index of first-hand domestic sales (PIF) together cover different price developments in domestic production, exports and imports. This PPI focuses on goods produced in Norway; first-hand domestic prices for imported goods are within the separate PIF series. The September figure refers to the month measured, while 9 October is the publication date. SSB scheduled its next PPI update for 9 November 2026. Until that release, these values are the latest published observations.
