Irish inflation rises notably to 2.7% in September 

Food prices, which rose by 4.7% in the 12 months to September, continue to outpace inflation

While food prices fell marginally on a monthly basis, down 0.2% compared to August, they have risen by 4.7% over the last 12 months.

Irish inflation ticked up notably in September, but was outpaced by a 5% annual rise in the price of food, latest figures from the Central Statistics Office (CSO) show. 

New data released on Tuesday found inflation, when measured using the EU Harmonised Index of Consumer Prices (HICP), rose by 2.7% in the 12 months to September, up from 1.9% in August. 

While food prices fell marginally on a monthly basis, down 0.2% compared to August, they rose by 4.7% over the last 12 months. Meanwhile, energy prices, which also fell on a monthly basis, were up by 1% compared to September 2024.

However, core inflation, which excludes volatile items like energy and unprocessed foods, was also found to have risen by 2.7% since September 2024. 

Speaking on the figures, CSO statistician Anthony Dawson said while annual inflation has risen, it should be noted that prices between August 2024 and September 2024 fell by 0.8%.

"The low base in September 2024 has had an impact on the annual change of 2.7% in the year to September 2025," Mr Dawson added. 

Eurostat will publish its flash estimates of inflation from the EU's HICP for the Eurozone on Wednesday. However, analysts believe it is unlikely to alter expectations that the European Central Bank will keep interest rates near current levels through early 2027.

The consumer price index (CPI) is the official measure of inflation in Ireland, while the HICP is an index of consumer prices that has been harmonised to allow for comparisons across euro area countries. While the CPI includes mortgage rates in its basket of goods, the HICP does not.
