Poland’s consumer prices extended their decline in June 2026, with the month-on-month Consumer Price Index (CPI) dropping 0.5%, according to data updated on 30 June 2026. This marks a further move into deflationary territory after a 0.3% month-on-month decrease recorded in May 2026.
The June reading shows that price pressures are not only subdued but intensifying on a short-term basis, as the pace of decline in prices accelerated compared with the previous month. On a month-over-month basis, the current -0.5% figure reflects a deeper contraction than May’s -0.3%, indicating weakening demand or persistent downward pressure on key components of the consumer basket.
Investors and policymakers will be watching subsequent data closely to assess whether this back-to-back decline in prices signals a temporary correction or a more entrenched deflationary trend, with potential implications for monetary policy and growth expectations in Poland.
