Competition and antitrust law in Mexico is the professional legal and regulatory function through which commercial agreements, market conduct and concentrations are assessed under the Federal Economic Competition Law. Following the 2025 institutional reform, the National Antimonopoly Commission, or CNA, is the central federal competition authority within the Ministry of Economy, replacing the Federal Economic Competition Commission, COFECE, and taking over competition functions previously shared with the Federal Telecommunications Institute.
Mexican competition analysis begins with commercial facts: the parties, relevant markets, agreement terms, pricing, market shares, customer alternatives, Mexican sales, Mexican assets, transaction value, corporate control and internal decision records. Matters may concern absolute monopolistic practices, relative monopolistic practices, unlawful concentrations, essential facilities, barriers to competition, declared market power or authority investigation.
Mexico has an independent competition regime outside the EU and EEA. Mexican analysis commonly requires coordination with United States, Canada, EU, Latin American, Asian and global competition-law workstreams in cross-border transactions and regional supply chains.
A distinctive Mexican feature is that concentration thresholds are expressed in Units of Measurement and Update, or UMA, and are therefore indexed. Under the reformed Article 86 framework, notification may be triggered by transaction value, acquisition percentage combined with Mexican assets or sales, or the combined Mexican assets or sales of the parties.
| Definition | The professional legal and regulatory function concerned with assessing, structuring, reviewing and managing competition and antitrust issues in Mexico, including absolute and relative monopolistic practices, concentrations, National Antimonopoly Commission procedure and cross-border coordination. |
| Object | Competition & Antitrust Law |
| Object Type | Professional Legal and Regulatory Control Function |
| Classification | Federal Economic Competition Law | Absolute Monopolistic Practices | Relative Monopolistic Practices | Concentrations | UMA Thresholds | Federal and Cross-Border |
| Jurisdiction | Mexico with federal and international relevance |
This section defines the practical boundaries of the Competition & Antitrust Law Registry Object. It distinguishes Mexican competition law from broader consumer, foreign-investment, telecommunications, data, public-procurement, sector-regulatory and corporate work that may connect to a matter without forming its primary competition-law issue.
| Covered Matters | Absolute monopolistic practices, relative monopolistic practices, cartels, bid rigging, abuse of dominance, concentrations, Article 86 UMA thresholds, Mexican sales and assets analysis, authority procedure, remedies and compliance. |
| Functional Boundary | The Registry Object covers how businesses assess and manage Mexican competition-law exposure through Federal Economic Competition Law analysis, CNA process, compliance controls and cross-border planning. |
| Related but Not Primary | Consumer protection, foreign investment, telecommunications, energy, financial regulation, data protection, public procurement, taxation and general corporate law may intersect with competition-law matters but are not the primary object. |
| Outside Scope | General business strategy without competition relevance, unrelated disputes and non-regulatory pricing advice. |
The purpose of Mexican competition and antitrust law is to protect the process of competition and free market access, prevent and sanction monopolistic practices, control harmful concentrations and remove barriers to competition.
The professional function translates commercial strategy into legally assessed conduct so businesses can identify risk before it becomes authority investigation, fine, remedy, transaction delay, criminal exposure for cartel conduct or litigation exposure.
A legally and operationally coherent competition-law position in Mexico, including identified risks, documented Mexican sales, asset and transaction-value assessment, correct CNA route, compliance controls and alignment with cross-border business activity.
Request contexts show the situations in which Mexican competition-law work is typically activated.
| Identity Pattern | Mexican company changing distribution systems, investor planning an acquisition, company with market power, trade association, supplier network, infrastructure operator, technology platform, state-linked undertaking or foreign group entering Mexican markets. |
| Business Event | Acquisition, merger, joint venture, asset transfer, pricing-policy change, competitor contact, exclusivity arrangement, concentration notification, authority contact, complaint, investigation or procurement concern. |
| Typical User | Board members, general counsel, compliance teams, transaction teams, external competition lawyers, private equity sponsors, technology businesses, infrastructure investors and multinational regulatory teams. |
| Typical Scenario | A transaction requires Mexican asset, sales and UMA threshold testing; an agreement needs review; a business faces dominance concerns; or a foreign group needs Mexican, United States and Canadian competition-law alignment. |
| Board or Executive Team | Needs competition-sensitive support before transactions, commercial coordination or market strategy changes. |
| General Counsel or Legal Team | Requires agreement review, authority response preparation, relative-monopolistic-practice analysis and compliance management. |
| Transaction Team or Investor | Needs concentration analysis, transaction-value testing, Mexican assets and sales review, UMA calculations and global filing coordination. |
| Commercial Leadership | Needs guardrails around distribution, exclusivity, pricing, information exchange and channel-management risk. |
| Foreign Parent Company | Needs Mexico-specific analysis aligned with United States, Canada, EU, Latin America, Asia-Pacific and other competition-law workstreams. |
| Transaction-Value Concentration Review | A concentration requires notification when the act or sequence of acts is valued in Mexico, directly or indirectly, above 16 million UMA. |
| 30% Acquisition Review | A concentration requires notification when it involves the acquisition of 30% or more of assets or capital stock of an economic agent whose Mexican annual sales or Mexican assets equal or exceed 16 million UMA. |
| Assets and Sales Concentration Review | A concentration requires notification when Mexican acquired assets or capital stock exceed 7.4 million UMA and participating economic agents have Mexican annual sales or assets exceeding 40 million UMA, jointly or separately. |
| Agreement Review | A distribution, supply, franchise, platform, trade-association or cooperation agreement requires review for absolute or relative monopolistic practices, exclusivity, resale-price maintenance, market allocation or information exchange. |
| Cross-Border Transaction | A foreign-to-foreign transaction requires Mexican concentration screening where it meets Mexican transaction-value, asset or sales thresholds and has effects in Mexican territory. |
Mexico has an independent federal competition regime with detailed statutory concentration thresholds and a modern enforcement framework for cartel conduct, unilateral practices and barriers to competition. The 2025 reform changed the institutional structure, placing the National Antimonopoly Commission within the Ministry of Economy.
| Operational Culture | Mexican competition work is structured, evidence-based and closely connected to statutory UMA calculations, Mexican sales and asset analysis, market definition, authority procedure and internal documentation. |
| Legal Framework Orientation | The Federal Economic Competition Law forms the core framework, supported by implementing provisions, authority guidance, judicial review and sector-specific rules. |
| Commercial Context | Mexico is a major North American and Latin American economy with substantial manufacturing, automotive, telecommunications, energy, consumer, financial-services, technology, infrastructure and cross-border supply-chain activity. |
| Language Expectation | Spanish is the official language for federal procedure. English is widely used in international transaction planning and group-level competition compliance work, subject to authority translation requirements. |
Mexico's principal competition authority is the National Antimonopoly Commission, or CNA, a decentralised body of the Ministry of Economy created by the 2025 reform. COFECE materials and case history remain relevant to understanding the Federal Economic Competition Law and prior practice, but current transactions should be screened against the reformed institutional framework and current procedural requirements.
| Official Name | Comisión Nacional Antimonopolio |
| Official English Name | National Antimonopoly Commission |
| Primary Role | Central Mexican federal authority responsible for competition enforcement, concentration control and functions previously exercised by COFECE and, in relevant competition matters, the Federal Telecommunications Institute. |
| Responsibilities | Reviews qualifying concentrations, investigates monopolistic practices and barriers to competition, applies remedies and sanctions, and administers competition-law procedures. |
| Typical Interaction | Concentration notifications, transaction-value and UMA threshold analysis, information requests, investigations, settlements, commitments, remedies and authority guidance. |
| Official Website | Ministry of Economy |
| Cross-Border Relevance | Highly relevant to Mexican elements of North American, Latin American and global transactions and conduct affecting Mexican markets. |
| Official Name | Comisión Federal de Competencia Económica |
| Official English Name | Federal Economic Competition Commission | COFECE |
| Primary Role | Predecessor federal competition authority whose statutory guidance, decisions, materials and enforcement history remain a significant reference point for Mexican competition law. |
| Responsibilities | Historically reviewed concentrations, investigated competition conduct, published guidance and enforced the Federal Economic Competition Law before the 2025 institutional reform. |
| Typical Interaction | Historic case law, merger guides, compliance materials, published decisions and Federal Economic Competition Law resources. |
| Official Website | cofece.mx |
| Cross-Border Relevance | Relevant to historical filings, precedent and the development of competition practice affecting multinational transactions. |
The principal Mexican framework is the Federal Economic Competition Law, or LFCE. The 2025 reform amended the institutional model and revised concentration thresholds. The relevant figures are expressed in UMA and therefore should be checked against the current annual UMA value.
| Official Title | Ley Federal de Competencia Económica | Federal Economic Competition Law |
| Year | 2014, as reformed |
| Purpose | Principal Mexican federal legislation governing absolute and relative monopolistic practices, concentrations, barriers to competition, essential facilities and authority powers. |
| Typical Application | Cartels, bid rigging, vertical restraints, abuse of dominance, concentration notification, market investigation, remedies and Mexican competition enforcement. |
| Related Legislation | 2025 reform legislation, implementing provisions, current authority rules and applicable sectoral legislation. |
| Official Source | Federal Economic Competition Law reference text |
| Current Status | In force as reformed. Current statutory text, authority procedures and annual UMA value should be consulted for current legal status. |
| Official Title | Article 86 | Concentration Notification Thresholds |
| Year | Current reformed framework |
| Purpose | Establishes compulsory prior notification of concentrations when specified transaction value, acquisition percentage, Mexican assets or Mexican sales thresholds are met. |
| Typical Application | 16 million UMA transaction-value threshold; 30% acquisition combined with 16 million UMA Mexican assets or sales; or 7.4 million UMA asset or capital-stock acquisition combined with 40 million UMA participant Mexican assets or sales. |
| Related Legislation | Federal Economic Competition Law, annual UMA determination, implementing regulations and authority procedural rules. |
| Official Source | Concentration notification guide reference |
| Current Status | In force as amended. The 2026 UMA value is MXN 117.31; current threshold values should be verified for the relevant year. |
Mexican competition-law work normally proceeds from commercial fact collection to market assessment, Mexican value and asset analysis, Article 86 threshold testing, CNA notification planning and continuing compliance monitoring.
| 1. Trigger Identification | Identify the agreement, market conduct, acquisition, merger, joint venture, asset transfer, complaint, procurement concern or authority event creating competition sensitivity. |
| 2. Market and Party Mapping | Identify parties, group relationships, relevant Mexican markets, transaction value, Mexican sales, Mexican assets, capital stock, market shares, control rights and foreign exposure. |
| 3. Legal Characterisation | Determine whether the matter concerns absolute monopolistic practices, relative monopolistic practices, concentration, barrier to competition, essential facility, exemption or procedural risk. |
| 4. Evidence Review | Review contracts, internal communications, pricing materials, market data, board records, audited financial statements and transaction documentation. |
| 5. Notification Assessment | Apply Article 86 thresholds using the current UMA: transaction value, 30% acquisition with Mexican assets or sales, or asset or capital accumulation combined with participant Mexican assets or sales. |
| 6. Strategy and Response | Prepare notification, compliance safeguards, agreement amendments, authority submissions, remedies analysis or transaction-timetable controls. |
| 7. Monitoring | Monitor authority engagement, internal conduct, transaction implementation and continuing consistency with Mexican competition assessment. |
| Typical Outputs | Risk memoranda, UMA threshold calculations, Mexican sales and assets analysis, concentration notifications, compliance protocols and authority-response materials. |
The decision tree simplifies threshold questions that commonly determine the correct Mexican competition-law route.
- Identify whether the issue concerns an agreement, market conduct, concentration, barrier to competition or essential facility.
- Confirm relevant Mexican markets, parties, group relationships, transaction value, acquired assets or shares, Mexican sales, Mexican assets and market shares.
- Assess whether absolute or relative monopolistic-practice provisions apply independently from merger control.
- For a concentration, apply all three Article 86 tests using the current annual UMA value.
- Assess sectoral, telecommunications, energy, foreign-investment and public-procurement interfaces where relevant.
- Notify and obtain authority approval before implementation if any applicable concentration threshold is met.
Mexican competition issues commonly arise before implementation and may continue through authority concentration review, information requests, investigation, remedies, judicial review or parallel foreign competition procedures.
| Commercial Planning | A business considers a transaction, distribution model, cooperation structure, pricing policy, platform rule, procurement approach or market strategy. |
| Initial Screening | Relevant teams identify Mexican market effects, transaction value, assets, sales, market shares, control structure, sector interface and authority jurisdiction. |
| Competition Assessment | The Federal Economic Competition Law framework and relevant foreign competition regimes are assessed against actual commercial facts. |
| Pre-Implementation Control | Before completion, parties determine whether notification, standstill, delay, redesign, commitment or safeguards are necessary. |
| Authority Phase | The CNA reviews the concentration, may request information, assess competition effects, consider remedies and issue its decision. |
| Operational Rollout | The agreement, conduct or transaction proceeds subject to approval, commitments, remedies, conditions or internal guidance. |
| Monitoring | The organisation monitors continuing compliance and whether market conditions or business conduct alter the Mexican legal risk position. |
| Enforcement or Appeal | The matter may progress to authority enforcement, court review, administrative penalties, criminal cartel exposure, damages claims or parallel foreign competition procedures. |
Mexican competition analysis depends on reliable documentation of commercial facts, transaction value, Mexican sales, Mexican assets, market shares, transaction structure, agreement terms and internal decision-making.

Mexico is a major North American and Latin American commercial hub. Mexican competition matters frequently require coordination with United States, Canada, EU, Latin American, Asian and other competition regimes where a transaction or conduct affects more than one market.
| Recognition | Mexican competition law often forms an independent and material component of a wider North American, Latin American and global competition assessment. |
| Foreign Companies | Foreign businesses may require Mexican competition and concentration analysis where their transactions or commercial arrangements meet Mexican transaction-value, asset or sales thresholds or have relevant local effects. |
| Language Considerations | Spanish is required for federal procedure; English is common in international transaction planning and group-level compliance work, subject to translation requirements. |
| International Rules | Mexican competition rules are independent from United States, Canadian, EU and other regimes, though transactions can require parallel foreign filings and coordinated authority engagement. |
| Practical Considerations | Mexican UMA calculations, sales and asset analysis, concentration filing, foreign filings, sectoral approvals, internal governance and transaction timing should be treated as coordinated workstreams. |
| Typical Risks | Using historical UMA thresholds, confusing legacy COFECE materials with current institutional procedure, or assuming a foreign-to-foreign transaction is outside Mexican control without testing Mexican value, assets and sales. |
- Mexico's concentration thresholds are UMA-indexed and must be recalculated using the applicable annual UMA value.
- The reformed Article 86 tests use 16 million UMA, 30%, 7.4 million UMA and 40 million UMA conditions.
- Qualifying concentrations require prior authority notification and clearance before implementation.
Operating constraints identify the recurring risks that can affect competition-law execution in Mexico.
| Annual UMA Risk | Statutory monetary thresholds are indexed to UMA, so peso values must be recalculated annually and not assumed from historical guidance. |
| Three-Test Risk | A concentration can require notification through transaction value, 30% acquisition plus Mexican sales or assets, or acquired Mexican assets or capital combined with party Mexican sales or assets. |
| Institutional Transition Risk | The 2025 reform replaced COFECE with the CNA; legacy materials are informative but current procedure should be verified with the new authority framework. |
| Conduct Risk | Cartel conduct can create severe administrative and criminal exposure, while relative monopolistic practices require detailed market-power analysis. |
| Documentation Risk | Transaction agreements, valuation materials, audited financial statements, market studies and internal communications are central to filing and defensibility. |
The cost profile of Mexican competition matters depends on transaction structure, current UMA calculations, Mexican sales and asset analysis, market definition, authority procedure, sector interfaces and cross-border coordination.
| Assessment and Advisory Work | Driven by transaction structure, Mexican value, asset and sales analysis, threshold testing, market assessment, sector screening and foreign filing coordination. |
| Concentration Notification | May require transaction documentation, financial statements, valuation analysis, market studies, Spanish-language materials and procedural management. |
| Review and Remedies | Authority information requests, economic evidence, commitments, remedies analysis and extended review can materially increase cost. |
| Investigation and Dispute Exposure | Authority response, evidence management, administrative fines, criminal-cartel exposure, court proceedings and international coordination may materially increase cost. |
The FAQ section collects recurring threshold questions in concise handbook format.
| Which Authority Is Central to Competition Law in Mexico? | Mexico's competition framework is now administered by the National Antimonopoly Commission, or CNA, a decentralised body of the Ministry of Economy that replaced COFECE and took over competition functions previously shared with IFT. |
| When Is a Concentration Notifiable in Mexico? | Under the reformed Federal Economic Competition Law, prior notification is required when any Article 86 threshold is met: transaction value above 16 million UMA; acquisition of 30% or more of an agent with Mexican sales or assets above 16 million UMA; or Mexican assets or shares above 7.4 million UMA where participants' Mexican sales or assets exceed 40 million UMA. |
| What Are the Approximate Mexican-Peso Thresholds for 2026? | With the UMA at MXN 117.31 from 1 February 2026, the principal figures are approximately MXN 1,876.96 million for 16 million UMA, MXN 868.09 million for 7.4 million UMA and MXN 4,692.40 million for 40 million UMA. |
| Can a Notifiable Concentration Close Before Approval in Mexico? | No. A concentration that meets the applicable thresholds must be notified and authorised before it is carried out; implementation before clearance creates gun-jumping risk. |
| Can a Foreign Company Need Mexican Competition Analysis? | Yes. Foreign businesses may need Mexican competition and concentration analysis where transactions or conduct meet Mexican thresholds or have relevant effects in Mexican territory. |
Practical guidance helps the reader prepare before engaging a competition professional or implementing a competition-sensitive decision in Mexico.
| Checklist | What is the conduct, agreement or concentration? Which Mexican markets are affected? What is the transaction value in Mexican territory? What assets or capital stock are acquired? What are the parties' Mexican annual sales and Mexican assets? Do any current Article 86 UMA thresholds apply? Is the relevant annual UMA value correctly used? Could telecommunications, energy, foreign-investment or other sectoral approvals apply? Are internal records consistent with the commercial rationale? |
