Poland’s core Consumer Price Index (CPI) inched higher in May 2026, rising to 3.1% year-over-year from 3.0% in April, according to data updated on 16 June 2026. The figure reflects price changes excluding volatile items and is measured against the same month a year earlier.
April’s reading had held steady at 3.0% year-on-year, but May’s slight uptick signals a modest re-acceleration in underlying inflationary pressures. Both the latest and previous figures are based on year-over-year comparisons, with the “actual” showing May 2026 versus May 2025, and the “previous” showing April 2026 versus April 2025.
The move from 3.0% to 3.1% remains marginal, yet it will be closely watched by markets and policymakers as they assess the persistence of core inflation in Poland and its implications for the future trajectory of monetary policy.
