The CNMC has concluded its investigation into BP, Cepsa (now Moeve), and Repsol regarding allegations of collusive pricing practices and abuse of collective dominance. The investigation was initiated following complaints from two industry associations in 2022.

These associations claimed that the companies had engaged in practices to increase their market share amid rising fuel prices due to the Russian invasion of Ukraine. Allegations included raising wholesale prices to independent gas stations and offering discounts to retail customers through loyalty programs.

However, the CNMC found no evidence of information exchange or concerted actions among the companies. It determined that there was no collective dominance, as Repsol's refining capacity and market share were significantly higher than those of BP and Cepsa, which acted independently.

In a separate case, Repsol was fined €20.5 million for abusing its dominant position in the wholesale fuel distribution market, where it was found to have engaged in practices that restricted competition.
