FX.co ★ Poland’s Monthly CPI Holds Steady at 0.7% in September, Signalling Stable Price Momentum

Poland’s consumer price index (CPI) rose by 0.7% month-over-month in September 2026, unchanged from the 0.7% increase recorded in the previous month. The data, updated on 14 October 2026, indicate that the pace of price growth has stabilized on a short-term basis, with no acceleration or deceleration in monthly inflation compared with August.

On a month-over-month basis, the “actual” figure for September reflects price changes relative to August, while the “previous” figure captured August’s movement versus July. The identical 0.7% readings in both periods suggest that, at least over late summer and early autumn, inflationary pressures have remained consistent rather than building further or easing. This steady pattern will be closely watched by market participants and policymakers assessing the trajectory of inflation and its implications for interest rate decisions and broader economic conditions in Poland.
