On Wednesday 7 June 2023, Luxembourg's national statistics office, STATEC, announced that the country's national consumer price index recovered by 0.1% compared to the previous month.

The prices of food products continued the marked upward trend in March 2023 and gained 0.3% in monthly comparison while the aggregate of petroleum products fell by 4.3%.

The biggest increases compared to the previous month were observed for baby food (+3.6%), pasta and couscous (+2.5%) and potatoes (+2.1%). On the other hand, the prices of fresh vegetables (-3.0%) and fresh fish (-2.6%) fell compared to April. Price trends were also noted for alcoholic beverages: the price of wine increased by 1.8% while that of beer beer decreased by 2.3% compared to the previous month.

Decreases with a visible impact on inflation were noted for passenger transport by air (-4.2%) and mobile telephone services (-2.7%).

In addition, inflation was boosted by a rise in the prices of domestic services, which gained 2.6% in May 2023. This series is based on an administrative file containing the salaries of people in charge of housework in private households.

The annual inflation rate stood at 3.6% against 3.7% a month earlier. The underlying annual inflation rate lost 0.1 percentage point and stood at 4.8% in May 2023.
