Poland’s consumer price dynamics swung into negative territory in October 2026, with the month-over-month Consumer Price Index (CPI) reading coming in at -0.4%. This marks a notable reversal from September 2026, when prices rose 0.7% on a monthly basis. The latest data, updated on 30 October 2026, highlights a rapid cooling in short-term price pressures.

On a month-over-month basis, the current -0.4% print compares to the previous 0.7% increase, meaning that instead of prices accelerating further, the overall price level declined relative to September. According to the comparison methodology, the “actual” October figure measures the price change from September to October, while the “previous” figure reflects the change from August to September.

The shift from positive to negative monthly inflation suggests a significant change in near-term pricing trends in Poland, which market participants and policymakers will be watching closely for signals on future inflation paths and potential policy responses.
