Neuchâtel, 20.01.2026 — The Producer and Import Price Index fell in December 2025 by 0.2% compared with the previous month, reaching 104.3 points (December 2020 = 100). Compared with December 2024, the price level of the whole range of domestic and imported products fell by 1.8%. Average annual inflation stood at –1.0% in 2025. These are the results from the Federal Statistical Office (FSO).
In particular, lower prices compared with the previous month were recorded in the Producer Price Index for petroleum products and dairy products. Pharmaceutical preparations and petroleum and natural gas in particular were responsible for a fall in the Import Price Index compared with November 2025. Falling prices were also seen for petroleum products, motor vehicles and motor vehicle parts, and computers. In contrast, basic metals and semi-finished metal products as well as vegetables, melons and potatoes became more expensive.
The average annual inflation rate for 2025 corresponds to the rate of change between the annual average for 2025 and that for 2024. The annual average is equal to the arithmetic mean of the 12 monthly indices of the calendar year. Average annual inflation was –1.0% in 2025. This decline is due in particular to lower prices for pharmaceutical products. Petroleum products and electricity and gas also became cheaper. Food products saw higher prices, however. While domestic producer prices fell by 0.4%, import prices fell by 2.2%. In 2024, the average annual inflation rate was –1.7%, while in 2023 it was +0.2%.
