FX.co ★ Irish Inflation Accelerates to 4.1% in September, Reversing Recent Cooling Trend

Ireland’s consumer price inflation picked up in September 2026, with the Consumer Price Index (CPI) rising 4.1% year-over-year, up from 3.7% in August 2026. The latest figures, updated on 8 October 2026, indicate a renewed acceleration in price growth after signs of easing in the previous month.

The data are based on year-over-year comparisons, measuring how prices in a given month compare to the same month a year earlier. August’s 3.7% reading reflected the annual change in prices from August 2025 to August 2026, while September’s 4.1% figure compares September 2026 prices with those of September 2025.

The uptick suggests that inflationary pressures in Ireland remain persistent, with September interrupting the moderating trajectory seen earlier. Investors and policymakers will be watching upcoming releases closely for signs of whether this is a temporary bump or the start of a renewed upward trend in consumer prices.
