Rising fuel prices have once again become a central topic of debate within the transport sector. The transport federation Phenadismer, which primarily represents self-employed and small businesses, has requested the Government to implement Specific controls on oil companies and service stations in response to what they describe as "brutal" fuel price increases in recent days.
The organization believes that the rise in diesel prices may be occurring at a faster rate than justified by the evolution of the international energy market.

The price of diesel is approaching two euros per liter
According to the organization, the increase in fuel prices has accelerated after the resurgence of geopolitical tension in the Middle Eastwhich is directly impacting energy markets.
In some areas of Spain, the The price of diesel is now approaching 2 euros per liter, a figure that puts a lot of pressure on the profitability of transport companies.
Given this scenario, Fenadismer has requested the Ministries of Economy and Transport the activation of extraordinary market surveillance mechanisms with the aim of ensuring that the increases reflect real costs and not potential price-fixing abuses.
France is pushing for large-scale inspections
The Spanish transport employers' association is taking as a reference point the measures recently announced in France. The French Prime Minister, Sébastien Lecornu, has ordered the performance of 500 strategic checkpoints at service stations to analyze whether there are unjustified commercial margins resulting from the current international energy tension.
These types of actions seek to strengthen transparency in price formation and avoid possible distortions in the fuel market.
The “rocket effect” on fuel prices
Fenadismer denounces that the current market behavior is a response to the well-known “rocket effect”:
- Fuel price increases are passed on to the consumer immediately. when tensions arise in energy markets.
- Drops in the price of crude oil are transmitted much more slowly. to the pumps.
This phenomenon, which is recurrent in the energy sector, directly impacts carriers, especially self-employed individuals and small businesses that operate on very tight margins.
Furthermore, many operators cannot immediately pass on the fuel price increase to their rates, which exacerbates the pressure on their profitability.
Doubts about the real origin of the price increases
Another argument put forward by the transport federation is that Some of the fuel currently sold at service stations comes from reserves acquired before the rebound in the international price of oil..
For this reason, the organization considers it necessary to analyze whether the increases truly reflect the rise in energy costs or whether there are other factors at play. additional profit margins derived from the international context.
Request for a market surveillance plan
Given this situation, Fenadismer is demanding that the Executive activate a urgent inspection plan through the competent consumer and competition authorities.
The objective would be analyze price trends across the entire network of service stationsto detect possible irregularities and prevent the energy crisis from generating extraordinary profits for oil companies.
Direct impact on logistics and transport
The increase in diesel prices has an immediate impact on the entire logistics chain.
Road transport remains the main goods distribution system in SpainTherefore, any increase in fuel costs ends up being passed on to all productive sectors.
For the spare parts and component distribution sector, where the capillary logistics represents a significant part of the operating cost.The evolution of fuel prices will be one of the key factors that will determine profitability during 2026.
