Irish inflation rises to 3.4% as energy costs climb

Consumer price inflation in Ireland is estimated to have risen by 3.4 per cent in the 12 months to August, according to figures from the Central Statistics Office (CSO). The monthly increase was 0.6 per cent from July.

The rise was driven by energy prices, which increased by 4.3 per cent between July and August and by 11.8 per cent over the year, the CSO reported. Food prices fell by 0.2 per cent in the month but were up 0.1 per cent year on year.

The latest inflation figure is the highest in three months, with elevated oil prices already pushing the cost of a litre of motor fuel close to €2 in many forecourts despite government excise duty cuts, according to The Irish Times.

The data come ahead of euro zone inflation numbers expected to show an annual rate of at least 3 per cent in August. Markets are anticipating the European Central Bank (ECB) to announce another interest rate hike in September, with policymakers reportedly ready to act to contain the side effects of the Iran war, as reported by Reuters.

Germany's two-year government bond yield, a sensitive gauge for rate expectations, hit its highest level since July 2024, The Irish Times noted.

The CSO's Harmonised Index of Consumer Prices (HICP) for Ireland showed an annual rate of 3.1 per cent in the 12 months to July 2026, compared with a 2.9 per cent annual increase for the euro zone in the same period. The HICP excluding energy and unprocessed food prices was estimated to have risen by 2.6 per cent since August 2025.

Service prices were unchanged in the month and rose by 3.7 per cent in the year to August, the CSO said.

Chris Weston, head of research at Pepperstone Group, said that European inflation dynamics coming through this week may affect the probability of a rate hike.

Market and policy context

The latest Irish HICP figure will feed into wider euro zone inflation numbers due out on Tuesday. The ECB's target is 2 per cent, and inflation has been above that level, supporting expectations for another rate increase.

The rise in energy prices has been linked to the US-Iran conflict, which has contributed to a second energy price shock and aggravated cost-of-living pressures in Western countries, according to The Irish Times. However, the long-term trajectory of inflation remains uncertain, with some analysts suggesting the ECB may not signal further tightening beyond September.
