Overview
- The CBS snelle raming, published Friday, reported annual CPI inflation of 3.4% for September 2026 with prices up 0.1% from August.
- The harmonized measure used across Europe, the HICP, was provisionally 3.0% in September, slightly higher than in August.
- CBS and reporting outlets point to higher fuel and energy costs as the main upward driver while food prices were weaker year on year.
- The figures are provisional because source data are incomplete and the CBS will publish the full, detailed CPI breakdown on 13 October 2026.
- Since 2026 the CPI and HICP use a new base year of 2025=100, which changes index reference levels and should be noted when comparing series across years.
