Poland’s core Consumer Price Index (CPI) eased to 3.1% year-over-year in September 2026, down from 3.3% in August 2026, according to data updated on 15 October 2026. The reading, measured on a year-over-year basis, confirms a further moderation in underlying price pressures in the Polish economy.
The September figure means that core inflation—stripping out volatile items—continued its gradual downward trajectory. The “previous” indicator of 3.3% reflected August’s price changes versus August a year earlier, while the “actual” 3.1% shows how prices in September 2026 compare with September 2025, highlighting a continued easing in annual core price growth.
The latest data may be closely watched by policymakers and markets as a sign that underlying inflation dynamics are slowly normalizing, potentially shaping expectations for the future path of monetary policy in Poland.
