Irish Inflation Surges to 3.6% as Iran War Drives Energy Costs Up 11% in a Month
Ireland's inflation rate has jumped sharply to 3.6% in March 2026, up from 2.5% in February, as the ongoing war in Iran disrupts global oil and gas supplies and pushes energy costs to their highest level in years.
The Central Statistics Office (CSO) flash estimate, published on 30 March, showed energy prices rising by 11.1% in March alone and by 12.3% over the preceding 12 months. The figures were compiled in mid-March, before the Irish government introduced measures to mitigate the impact of rising fuel costs, meaning the full effect of the conflict has yet to be captured in official data.
Key Developments
The surge in energy costs is directly linked to the effective closure of the Strait of Hormuz following the outbreak of the US-Iran war in late February. Brent crude, the international benchmark, has exceeded $116 (€101) a barrel, with global oil and gas shipments severely disrupted by the conflict.
Economists from Davy noted that without the Middle East conflict, Ireland's headline inflation would likely have been around 2.3% in March. The Bank of Ireland has warned that inflation could rise to 4%, while the ESRI has projected an average of 3.2% for 2026 as a whole.
Food prices fell slightly by 0.3% in March, though they remain 2.3% higher than a year ago. Services prices rose by 0.9% in the month and 3.3% over the year. Core inflation — excluding energy, food, alcohol, and tobacco — held at 2.7% year-on-year.
Background
Ireland's economy had been performing strongly in early 2026, with the government running a significant budget surplus. However, the Iran war has introduced a significant external shock, with energy-intensive sectors of the Irish economy particularly exposed to rising costs. The government has already reduced fuel excise duties in response, though opposition parties are calling for further intervention.
Sinn Féin's energy spokesperson Pa Daly and Green Party leader Roderic O'Gorman have both called for additional cuts to fuel excise duties, the removal of planned carbon tax increases, and the reintroduction of targeted energy credits for households.
Why It Matters
Rising inflation erodes household purchasing power and puts pressure on the European Central Bank to reconsider its interest rate path. For Irish families already dealing with a housing crisis and high cost of living, the energy price surge represents a significant additional burden heading into spring and summer.
What's Next
The government is expected to announce further cost-of-living measures in the coming weeks. The ECB has indicated readiness to increase interest rates if the rise in eurozone inflation proves more than temporary. Full details of the CSO data are available at The Irish Times.
