We preserve and guarantee the existence of effective competition in the markets throughout Spain, since this is fundamental for proper functioning of a free market economy and for the well-being of consumers.
We investigate anti-competitive practices among companies, abuses of dominant positions, and other prohibited practices that have a negative impact on competition in the markets.
We offer a way out for those who have participated in cartels, in exchange for their help with ending these anti-competitive practices.
We apply data analysis and artificial intelligence for the ex officio detection of anti-competitive practices.
Access to the 3 available channels, which preserve anonymity and confidentiality, and through which any citizen can report indications of anti-competitive behaviour.
We oversee compliance with the Resolutions passed by the CNMC's Council, including payment of fines.
We monitor concentrations among companies to prevent these from putting competition in the markets at risk.
We collaborate with and coordinate our efforts with the Authorities on Competition from Spain's Autonomous Communities.
We collaborate as part of the European Competition Network (ECN) to help ensure compliance with regulations on this subject throughout the European Economic Area. We coordinate our actions with other international entities.
