Year-on-year inflation in Poland slowed in June 2026, with the Consumer Price Index (CPI) rising 2.5% compared with the same month a year earlier, down from 3.1% recorded in May 2026.
Both figures are calculated on a year-over-year basis, meaning the June reading reflects how prices changed relative to June of the previous year, while the May figure compared prices to May a year earlier. The latest data, updated on 30 June 2026, indicates a further easing in price pressures, suggesting that inflationary momentum in Poland continued to moderate at the end of the second quarter.
