Prices started to show a monthly decline of 0.6% in December, according to the latest Statec figures. The inflation rate fell from 5.9% to 5.4%. This drop is due in particular to the prices of petroleum products, which fell by 8.8%.

In December, prices rose by 5.4% in Luxembourg over one year, compared with 5.9% , announced on Monday 9 January. The annual decline in the inflation rate is the result of a decrease in the price of petroleum products.

At the pump in December, motorists paid 11.5% less for a litre of diesel and 12.3% less for a litre of petrol. The cost of heating oil fell by 18%. However, despite this month-on-month decline, the prices of oil-based products remain very important in the national consumer price index basket, accounting for 15.8% of the basket compared to December 2021.

Wage indexation will wait

As a direct consequence of this decline, the next wage indexation will not take place in January. Last July, in drawing up a central scenario, Statec estimated that a . For the time being, with the inflation rate falling and the annual core inflation rate dropping by 0.3 points to 4.6% in December, the indexation mechanism will not be triggered.

More technically, the general index for the month of December expressed in base 100 in 2015 is 117.06 points. The half-yearly average of the index connected to the 1.1.1948 base rises from 963.34 to 963.76 points. “The next indexation will therefore be triggered when the value of 964.64 is reached,” Statec states in its latest analysis, without giving a precise date for when this index bracket will be crossed.

The indexation tranche initially planned for last July, and postponed in accordance with a tripartite agreement, will be automatically triggered on 1 April. This will put an end to the compensation mechanism created to help households and indirectly help employers, the energy tax credit (CIE).

More expensive fresh vegetables and fish

While the prices of petroleum products have fallen, this is not the case for all the other elements of the consumer basket. With the exception of fees for non-formal education (-15% following the entry into force of the law on free non-formal education), many items have risen.
