Ireland’s EU-harmonised consumer price inflation (HICP) rose to 4.0% year-on-year in October 2026, up from 3.9% in September, reaching its highest level since September 2023. The pickup was mainly driven by energy prices, which increased by 18.3% compared with 15.3% in the previous month. By contrast, food inflation slowed to 0.1% from 0.3%, while services inflation eased to 3.5% from 4.1%. Core inflation, excluding energy and unprocessed food, also decelerated to 2.5% from 2.8%. On a monthly basis, harmonised consumer prices rose by 0.5% in October, compared with a 0.2% increase in September.
