Switzerland’s producer and import prices declined by 1.8% year-on-year in September 2025, the same pace as in the previous month. This marked the 29th consecutive month of producer deflation and remained the sharpest since December of last year. The downturn was driven by decreases in both producer prices (-1.4% vs -1.3% in August) and imports costs (-2.7% vs -2.7%). On a monthly basis, producer and import prices fell by 0.2% in September, following a 0.6% loss in the preceding period, with petroleum and natural gas as well as petroleum products contributing most to the drop. Conversely, green coffee became more expensive.
