Competition Law and Antitrust Regulations in Turkey: A Guide for Foreign Investors

For foreign companies entering the Turkish market - whether through acquisitions, joint ventures, or organic growth - understanding Turkey’s competition law framework is essential. The Turkish Competition Authority (Rekabet Kurumu) actively enforces antitrust rules, and non-compliance can result in substantial fines, voided agreements, and reputational damage.

This guide covers the key pillars of Turkish competition law, merger control requirements, and practical compliance strategies for foreign investors.

The Legal Framework: Law No. 4054

Turkey’s competition regime is governed by Law No. 4054 on the Protection of Competition, enacted in 1994 and modeled closely on EU competition law. The law is enforced by the Turkish Competition Authority (TCA), an independent regulatory body with broad investigative and sanctioning powers.

Law No. 4054 rests on three core prohibitions:

1. Anticompetitive agreements (Article 4)
2. Abuse of dominant position (Article 6)
3. Mergers and acquisitions that significantly reduce competition (Article 7)

Alignment with EU Standards

Turkey’s competition law is closely aligned with EU antitrust principles, making it relatively familiar to European investors. The TCA regularly references EU case law and European Commission guidelines in its decisions, providing a degree of predictability for companies already operating under EU competition rules.

Anticompetitive Agreements (Article 4)

Article 4 prohibits agreements, concerted practices, and decisions by associations of undertakings that have the object or effect of preventing, restricting, or distorting competition. This includes:

• Price-fixing between competitors
• Market allocation or customer-sharing agreements
• Bid rigging in public or private tenders
• Resale price maintenance (RPM) in vertical agreements
• Output restrictions or production quotas
• Information exchange that facilitates coordination

Block Exemptions

Similar to EU law, Turkey offers block exemption communiqués for certain categories of agreements that, while potentially restrictive, generate efficiencies. Key block exemptions include:

• Vertical agreements - Distribution and supply agreements are generally permitted if the supplier’s market share does not exceed 40%. However, hardcore restrictions like fixed resale prices remain prohibited.
• R&D agreements - Collaborative research arrangements between competitors are exempted under certain market share thresholds.
• Technology transfer agreements - Licensing arrangements benefit from exemptions when parties’ combined market share stays below defined limits.
• Insurance sector agreements - Specific exemptions apply for joint calculations, standard policy conditions, and co-insurance pools.

Practical Tip for Foreign Investors

If you are establishing a distribution network in Turkey, carefully review your vertical agreements. The TCA has been increasingly active in investigating resale price maintenance and territorial restrictions in distribution contracts. Ensure your agreements include recommended (not fixed) prices and avoid absolute territorial protection for distributors.

Abuse of Dominant Position (Article 6)

Companies holding a dominant position in a relevant market are prohibited from abusing that position. Dominance itself is not illegal - only its abuse.

Conduct that may constitute abuse includes:

• Excessive or predatory pricing
• Refusal to deal or supply without objective justification
• Tying and bundling products or services
• Exclusionary rebates or loyalty discounts designed to foreclose competitors
• Discriminatory treatment of trading partners in equivalent transactions

How Dominance Is Assessed

The TCA considers multiple factors when assessing dominance:

• Market share - A share exceeding 40% generally raises a presumption of dominance, though it is not conclusive
• Barriers to entry - Regulatory, financial, or technological barriers
• Buyer power - Whether customers have credible alternatives
• Market structure - Number and strength of competitors

Collective Dominance

Turkish law also recognizes collective dominance, where two or more companies that are not individually dominant can be found to hold a joint dominant position and abuse it through parallel conduct or tacit coordination.

Merger Control: Mandatory Notification

Turkey operates a mandatory pre-notification system for mergers and acquisitions that meet specified turnover thresholds. Transactions that cross these thresholds cannot be completed until the TCA grants clearance.

Current Thresholds (2025-2026)

A transaction must be notified to the TCA if:

• The combined Turkish turnover of the parties exceeds TRY 750 million, and
• The individual Turkish turnover of at least two of the parties each exceeds TRY 250 million

Or alternatively:

• The Turkish turnover of the acquired party (in acquisitions) or any of the parties (in mergers) exceeds TRY 250 million, and
• The worldwide turnover of at least one of the other parties exceeds TRY 3 billion

Important: These thresholds are updated periodically. Always verify the current thresholds with the TCA or your legal advisor before proceeding with a transaction.

The Review Process

The TCA’s merger review follows a two-phase structure:

Phase	Duration	Outcome
Phase I	30 calendar days	Clearance, conditional clearance, or referral to Phase II
Phase II	Up to 6 months (extendable)	In-depth review for transactions raising serious competition concerns

The vast majority of notified transactions receive Phase I clearance. Phase II investigations are relatively rare but can involve extensive information requests and market testing.

Gun-Jumping Risk

Completing a notifiable transaction without TCA clearance constitutes gun-jumping and can result in:

• Fines of up to 0.1% of the turnover generated in the financial year preceding the decision
• The transaction being declared null and void
• Orders to unwind the transaction

Foreign investors involved in global M&A transactions should not overlook Turkish filing requirements, even if Turkey is a secondary market.

Enforcement and Penalties

The TCA has broad enforcement powers and has become increasingly active in recent years.

Fines

• Anticompetitive agreements: Fines of up to 10% of the company’s annual Turkish turnover
• Abuse of dominance: Fines of up to 10% of annual Turkish turnover
• Failure to notify mergers: Up to 0.1% of annual Turkish turnover
• Individual liability: Managers and employees who played a determinative role in the infringement can be fined up to 5% of the fine imposed on the company

Leniency Program

Turkey operates a leniency program for cartel participants. The first applicant to provide evidence of a cartel can receive full immunity from fines, while subsequent applicants may receive reductions of 33% to 50%. This program has been instrumental in the TCA’s cartel detection efforts.

Private Enforcement

Companies harmed by anticompetitive conduct can pursue private damages claims before Turkish commercial courts. Claimants can seek compensation for actual damages, and courts may award up to three times the actual damage in cases involving cartels.

Sector-Specific Considerations

Digital Markets and E-Commerce

The TCA has been increasingly focused on competition in digital markets, including:

• Platform-to-business relationships
• Self-preferencing by dominant platforms
• Data-driven market power
• Most-favored-nation (MFN) clauses in online distribution

Turkey has also introduced amendments to strengthen oversight of digital platforms through its e-commerce regulations, which interact with competition law principles.

Energy and Telecommunications

The energy and telecommunications sectors have sector-specific regulators (EPDK and BTK, respectively), but the TCA retains jurisdiction over competition matters. Foreign investors in these sectors should be aware of overlapping regulatory requirements.

Financial Services

Banking and insurance activities are subject to additional oversight by the BDDK (Banking Regulation and Supervision Agency) and the insurance regulator. However, competition law applies fully, and the TCA has investigated numerous cases involving financial services.

Compliance Best Practices for Foreign Investors

1. Conduct a Competition Law Audit

Before entering the Turkish market, assess your business practices against Turkish competition law requirements. Key areas to review include:

• Distribution and supply agreements
• Pricing policies
• Information exchanges with competitors (including through trade associations)
• Existing dominant positions

2. Implement a Compliance Program

Establish a competition law compliance program that includes:

• Written policies and guidelines tailored to Turkish law
• Regular training for employees, especially sales and procurement teams
• Clear escalation procedures for potential competition issues
• Document retention policies that account for TCA investigation powers

3. Monitor Merger Thresholds

For companies engaged in serial acquisitions or joint ventures, continuously monitor whether upcoming transactions will trigger Turkish filing obligations. The TCA does not grant retroactive clearance.

4. Engage Local Legal Counsel

Turkish competition law has nuances that differ from EU or US antitrust regimes. Engaging experienced local competition counsel is essential for:

• Drafting compliant commercial agreements
• Preparing merger notifications
• Responding to TCA investigations or information requests
• Filing leniency applications when needed

5. Participate in Public Consultations

The TCA regularly publishes draft guidelines and communiqués for public consultation. Foreign investors and industry associations should actively participate to shape regulatory developments that affect their business.

Recent Developments

The Turkish competition landscape continues to evolve:

• Increased digital market focus - The TCA has launched multiple investigations into technology companies and platform practices
• Settlement mechanism - A formal settlement procedure has been introduced, allowing companies to resolve investigations more efficiently in exchange for a 25% fine reduction
• Commitment mechanism - Companies can offer behavioral or structural commitments to address the TCA’s concerns without a formal infringement finding
• Dawn raids - The TCA has intensified its use of unannounced inspections (dawn raids) and digital forensic tools
