1. Purpose and Legal Framework
The system of fines and sanctions under Turkish Competition Law serves as a crucial mechanism to ensure compliance, deter anti-competitive conduct, and preserve the integrity of market competition. These fines are not merely punitive — they are preventive, corrective, and designed to promote a culture of fair competition in line with international (especially EU) standards.
The legal foundation of the fine regime is established by Law No. 4054 on the Protection of Competition, particularly Articles 16 and 17, along with the Regulation on Fines to be Imposed in Cases of Agreements, Concerted Practices, Decisions, and Abuses of Dominant Position and the Guidelines on Fines, most recently updated in December 2024. The enforcement of these rules lies with the Turkish Competition Authority (TCA), an autonomous body responsible for investigating infringements and imposing administrative monetary sanctions through its decision-making arm, the Competition Board.
2. Types of Infringements Leading to Fines
The Competition Authority may impose fines for several types of violations under Law No. 4054, including:
a. Anti-Competitive Agreements (Article 4)
This covers horizontal and vertical agreements, concerted practices, or decisions by associations of undertakings that prevent, restrict, or distort competition.
Examples:
- Price fixing or resale price maintenance
- Market or customer allocation
- Output limitation or bid-rigging
- Exchange of commercially sensitive information
b. Abuse of Dominant Position (Article 6)
An undertaking in a dominant market position may not abuse that power. Typical forms of abuse include:
- Predatory pricing or exclusionary behavior
- Tying and bundling practices
- Discriminatory pricing between customers
- Refusal to deal without objective justification
c. Merger Control Violations (Article 7)
Transactions that meet the notification thresholds must be submitted for clearance before closing. Implementing a merger or acquisition before authorization (“gun-jumping”) or failing to notify can trigger administrative fines and invalidate the transaction under Turkish law.
d. Procedural or Non-Compliance Violations
These include obstruction of on-site inspections, failure to provide accurate information, non-compliance with Board decisions or commitments, and breach of interim measures.
3. Determination and Calculation of Fines
The calculation of fines and sanctions under Turkish Competition Law depends on turnover, duration, and aggravating factors. The fines under Law No. 4054 are administrative monetary penalties and are determined using a structured methodology. The maximum limit for undertakings is 10% of their annual gross turnover in the preceding financial year.
a. Base Fine Rate
The starting point depends on the gravity of the infringement:
- Minor violations (e.g., vertical restraints): 2–4% of annual turnover
- Serious infringements (e.g., abuse of dominance): 4–8%
- Hardcore cartels (price-fixing, bid-rigging): 8–10%
b. Duration of Infringement
Longer infringements trigger incremental increases:
- 1–2 years: +20%
- 2–3 years: +40%
- 3–4 years: +60%
- 4–5 years: +80%
- Over 5 years: +100%
c. Aggravating and Mitigating Factors
The Board may increase or reduce the fine considering:
- Aggravating: repeated offenses, leadership in a cartel, obstruction of investigation
- Mitigating: cooperation with the TCA, limited participation, minor market share, voluntary termination of infringement
d. Fines on Individuals
Managers or employees who had a decisive influence on the infringement may also be fined up to 5% of the total fine imposed on the company.
e. Daily Fines for Non-Compliance
Failure to comply with the Board’s interim or final decisions may result in daily fines (e.g., per-day penalties imposed on major digital platforms for delayed compliance).
4. The Leniency Program: Immunity and Reduction of Fines
One of the most effective mechanisms for uncovering cartels and promoting compliance is the Leniency Program, introduced under the Regulation on Active Cooperation for Detecting Cartels.
Purpose of the Leniency Program
The leniency system aims to encourage cartel participants to self-report their involvement in anti-competitive agreements and cooperate with the Competition Authority in exchange for full or partial immunity from fines. This mechanism enhances detection efficiency and disrupts secret cartels that are otherwise difficult to prove.
Who Can Apply for Leniency?
- Undertakings that have participated in a cartel (e.g., price-fixing, bid-rigging, market-sharing).
- Managers or employees of these undertakings may also apply individually if they played a role in the infringement.
Conditions for Leniency
To qualify for full or partial immunity, the applicant must:
- Submit information or evidence that enables the TCA to initiate or advance an investigation.
- Cooperate fully throughout the investigation.
- Cease participation in the cartel immediately upon applying.
- Not destroy or conceal evidence and not disclose the application to other parties.
Types of Leniency Benefits
| Timing of Application | Possible Reduction |
| First applicant providing decisive evidence | Full immunity (100%) |
| Second applicant | 30–50% reduction |
| Third applicant | 20–30% reduction |
| Subsequent applicants | Up to 20% reduction |
Practical Impact
This system has proven highly effective in uncovering concealed cartels. Companies that voluntarily cooperate not only avoid or reduce penalties but also demonstrate a commitment to ethical business conduct. The TCA often uses leniency evidence as a foundation for larger investigations, significantly expanding enforcement reach.
5. Settlement Mechanism
Apart from leniency, the Settlement Procedure—introduced in 2021—allows undertakings to admit the infringement and accept the Board’s findings before the final decision in return for a fine reduction of up to 25%. Settlement accelerates proceedings and reduces litigation risks, benefiting both undertakings and the Authority.
6. Enforcement and Illustrative Cases
Recent high-profile cases demonstrate the TCA’s active stance and strict enforcement policy:
- Google (2024): fined ₺482 million for discriminatory practices in hotel searches.
- Meta (2024): fined ₺1.2 billion for abusing its dominance in data integration and advertising.
- Electronics Companies (2023): several firms fined for resale price maintenance (RPM).
These decisions highlight the Authority’s readiness to impose substantial sanctions to deter future misconduct.
The Turkish competition fine regime reflects a balance between deterrence and compliance. The system not only penalizes anti-competitive behavior but also provides structured opportunities—through leniency and settlement—for businesses to demonstrate cooperation and integrity.
As enforcement continues to align closely with EU practices, undertakings operating in Turkey must prioritize competition compliance programs, internal audits, and legal awareness to mitigate risks and ensure alignment with fair market principles.
