The Central Bank of Poland published its September 2025 core inflation indicators, reporting Consumer Price Index (CPI) inflation of 2.9% year-on-year and core inflation excluding food and energy prices of 3.2% y/y, unchanged from the previous month. Across the other core measures, inflation excluding administered (state-controlled) prices was 2.5% y/y (unchanged), inflation excluding the most volatile prices eased to 3.7% y/y (from 3.8%), and the 15% trimmed mean fell to 2.9% y/y (from 3.0%). The bank reiterated that it publishes four core indices monthly to support analysis of the sources and persistence of inflation, noting that the ex-food-and-energy measure is commonly used by analysts because it is more responsive to monetary policy, while food and energy prices are more influenced by weather and global market conditions.
