Energy and services drive the increase
Annual inflation across the euro area accelerated from 3.0% in April to 3.2% in May 2026, with energy remaining the component recording the strongest price growth.
Energy prices increased by 10.8% year over year, matching April’s rate. Services inflation rose more noticeably, advancing from 3.0% to 3.5%.
Food inflation slows during May
Food, alcohol and tobacco prices increased by 1.9%, down from 2.4% in April. Meanwhile, annual inflation for non-energy industrial goods edged up from 0.8% to 0.9%.
The figures show that May’s higher headline rate resulted primarily from stronger services inflation, while easing food costs provided a partial counterbalance.
Services carry the greatest weight
The impact of each category on overall inflation depends on its share of household monetary consumption. In the 2026 Harmonised Index of Consumer Prices, services represent approximately 46.7% of euro area expenditure, making them the largest component.
Non-energy industrial goods account for around 25.3%, followed by food, alcohol and tobacco at 19.0%. Energy has the smallest weighting, representing about 9.0% of expenditure.
Volatile categories can reshape inflation
Food, alcohol, tobacco and energy together make up less than one third of household spending. Despite their lower combined weight, they can have a substantial effect on headline inflation because their prices generally fluctuate more sharply than those of services and industrial goods.
Euro area membership changes the comparison
The calculations use Harmonised Index of Consumer Prices data available on 17 June 2026 and reflect the changing composition of the currency bloc.
Monthly figures through December 2025 cover the 20-country euro area. Data beginning in January 2026 correspond to its expanded composition of 21 member countries.
