CNMC Market Definitions

English-language access to CNMC merger decisions — Spanish competition law made searchable

About CNMC

The Comisión Nacional de Mercados y la Competencia (CNMC) is Spain's integrated national competition and sector regulator, created in 2013 by merging the former CNC with sector regulators for telecoms, energy, and transport. It reviews mergers with a Spanish dimension and enforces Spanish competition law, which is aligned with EU competition rules. Spain's €1.4 trillion economy generates substantial merger control case law in energy, telecoms, media, and distribution. Decisions are published in Spanish.

Why CNMC Market Definitions Matter

  • Spain is the EU's fourth-largest economy with an active merger control regime — CNMC market definitions in energy, telecoms, and distribution are not replicated in EC decisions
  • Spanish competition law provides an important reference for deals involving Spanish-speaking markets, including transactions where Spanish precedent is cited in Latin American jurisdictions
  • CNMC's integrated regulator status means its market definitions in regulated sectors (energy, telecoms, transport) carry particular authority for sector-specific competition analysis

Frequently Asked Questions

What is the CNMC?

The Comisión Nacional de Mercados y la Competencia (CNMC) is Spain's independent national competition and sector regulator, headquartered in Madrid. Created in 2013, it enforces Spain's Competition Defence Act (Ley de Defensa de la Competencia) and reviews mergers meeting Spanish turnover thresholds. Its integrated regulatory mandate covers competition, telecoms, energy, postal, audiovisual, and transport markets.

Are CNMC decisions published in English?

CNMC merger decisions are published in Spanish. The authority provides limited English summaries for some major decisions. CuriAI makes CNMC market definitions searchable in English, enabling non-Spanish speakers to access Iberian competition law precedents.

What are the Spanish merger control thresholds?

Transactions must be notified to the CNMC when the parties' combined Spanish market share in any relevant market exceeds 30% with at least €240m combined Spanish turnover, or when the parties' combined Spanish turnover exceeds €240m and at least two parties each have Spanish turnover above €60m.

Which sectors does the CNMC focus on?

CNMC is particularly active in energy (Repsol, Endesa, Iberdrola), telecommunications (Telefónica, Vodafone Spain, Orange Spain), media and audiovisual, food distribution and retail, and financial services. Its integrated regulatory role means market definitions in regulated sectors are especially detailed and carry additional legal weight.
