Luxembourg Inflation Rate Rises from 2.4% to 2.7% in September 2025

On Monday 6 October 2025, Luxembourg's national statistics institute, STATEC, reported that the annual inflation rate rose to 2.7% in September 2025, up from 2.4% in August.

According to STATEC, in September, the national consumer price index recorded a monthly decline of 0.1%. STATEC attributed this slight decrease mainly to lower travel costs. Travellers paid on average 11.2% less for their holidays than in August, while airfares fell by 17.6%. Administrative costs also declined by 7.5%.

Conversely, the evolution of services was affected by an 8.6% increase in nursery and childcare centre fees compared with the previous month. With the start of the school year, education-related costs rose by 6.2%. Municipal taxes also increased: +8.0% for water supply and +1.3% for wastewater collection. Price rises were also observed in the catering sector (+0.6%). Overall, the services aggregate rose by 2.5% year-on-year, compared with 2.7% in August.

Food prices (-0.1%) were broadly stable in September, although this masks offsetting movements at a more detailed level. Consumers paid less for frozen fish (-4.4%), pizzas and quiches (-2.1%) and baby food (-4.0%). However, other supermarket products saw price increases, notably meat (+0.4%), confectionery (+1.5%) and mineral water (+1.1%). Over the year, food prices were up 2.4%.

Overall costs for petroleum products increased by 0.6% compared with August: diesel prices increased by 0.6%, petrol by 1.1% and heating oil by 0.5%. Compared with September 2024, petroleum product prices were up 7.4%.

The annual core inflation rate remained stable at 2.4%. The general index for September, expressed on a 2015 base of 100, was 126.57 points. The half-yearly average of the index, linked to the 1 January 1948 base, rose from 1,030.48 to 1,033.72 points. STATEC noted that the next wage indexation will be triggered when the value reaches 1,038.79 points.
