Poland’s annual inflation rises to 4% in September

Original AI-generated illustration: a conceptual scene about everyday spending in Poland. The objects do not depict prices recorded in shops.

Consumer prices are rising faster again in Poland. In its flash estimate published on 30 September 2026, Statistics Poland, known as GUS, reports a 4% increase in September compared with the same month of 2025. Prices are up 0.7% compared with August 2026. These results remain preliminary.

An acceleration since August

Annual inflation stood at 3.4% in August, Gazeta.pl recalls in its report on the figures. The rate has therefore increased by 0.6 percentage points in September. The outlet highlights rising fuel prices as a particular contributor to the acceleration.

This comparison concerns the pace of price growth. It does not mean that every product has become 4% more expensive since last month, or that each shopping bill automatically costs 4% more.

Two figures, two comparisons

The 4% rate compares September 2026 with September 2025. The 0.7% figure compares September with August 2026. Both describe a statistical basket of goods and services rather than one individual’s purchases.

A household spending a large share of its budget on driving will not necessarily experience the same change as one mainly using public transport. The composition of spending matters alongside the headline figure.

Context for planning expenditure

For French-speaking residents in Poland and people planning a visit, the release offers useful context. It is a reason to update planned spending and compare the prices actually available for major purchases.

Applying this rate mechanically to a particular hotel, train ticket or restaurant would nevertheless be misleading. A national index helps describe the trend; observed prices remain the reference for building a budget.
