Between Prohibition and Permission: Trade Associations and the Rise of Informal Ex Ante Control in Information Exchange

1.     Introduction: Why Trade Associations Seek Clearance

Competition law limits the exchange of commercially sensitive information among competitors to preserve strategic uncertainty. Trade associations, on the other hand, exist precisely to collect and share industry-wide data that reduces uncertainty and improves market efficiency. This puts competition authorities in the position of drawing a line between information exchanges that enhance market efficiency and those that facilitate coordination.

Adding to this complexity, the same information-sharing mechanism may be entirely unobjectionable in one market yet problematic in another. The assessment depends on market structure, the strategic value of the data, and the design of the exchange mechanism. As a result, how information is collected, processed and disseminated often matters more than the mere fact that it is shared.

In increasingly data-driven markets, this assessment has become even more pressing. Technology has amplified the predictive power and processing speed of historical data, making trade associations key platforms for sector-wide information exchange. Businesses routinely seek negative clearance or exemption for proposed information-sharing systems before implementation.

Against this background, the Turkish Competition Authority’s (the “TCA” or the “Authority”) decisional practice reveals an implicit effort to calibrate market transparency — determining how much strategic uncertainty must be preserved within a given market. Rather than treating trade association-led information exchanges as inherently permissible or problematic, the Authority evaluates whether the design of the proposed system adequately mitigates coordination risks.

This article examines selected decisions to analyse how the Authority balances efficiency against strategic uncertainty, and considers whether this case-by-case approach enhances legal certainty or risks discouraging legitimate information exchange.

This growing attention is not without reason. The Authority’s recent decisional practice reveals a marked increase in the number and depth of its assessments concerning information exchange among competitors. The Authority quite frequently scrutinises the design and operation of information-sharing mechanisms with increasing frequency and detail. Several of these proceedings have resulted in the imposition of substantive remedies, ranging from the modification of data-sharing systems to the requirement of structural safeguards as a condition for exemption. This trend signals a hardening stance: the Authority appears to treat information exchange not merely as a peripheral dimension of competition enforcement, but as a standalone area of regulatory focus.

This shift is further evidenced by the Authority’s Human Resources Guidelines, which include detailed provisions on how information exchange should be structured among competitors, particularly in the context of employee compensation and benefits data. The Guidelines underscore that even in areas traditionally perceived as remote from core competitive parameters, the Authority expects compliance with the same structural safeguards — aggregation, anonymisation and temporal delays — that apply to product market data. Taken together, these developments suggest that the Authority is progressively expanding the boundaries of information exchange enforcement, making it essential for businesses and trade associations to design their data-sharing mechanisms with greater care and foresight.

2.     From Content to Design: How the Architecture of Data Sharing Matters

A defining feature of the Authority’s approach is a shift in focus: from what information is shared to how it is processed and disseminated. The case law consistently evaluates whether the exchange mechanism is designed to prevent undertakings from monitoring each other’s behaviour or aligning strategies.

In this context, aggregation and anonymisation are the central structural safeguards. Information is more likely to be cleared where it is presented in aggregated form, does not allow identification of individual undertakings, is sufficiently historicised to lose its strategic immediacy, and is shared at intervals that prevent continuous monitoring. These safeguards operate cumulatively: the absence of one may undermine the others.

The IMDER1 decisions illustrate how the Authority’s assessment evolves as the exchange mechanism is redesigned. In IMDER-I2, the Authority examined a reporting system covering new and second-hand construction machinery sales volumes and rental data.3 A critical concern was that the dataset included firm-specific sales volumes, 4enabling undertakings to monitor each other continuously throughout the year.5 On this basis, neither negative clearance nor exemption was granted.6

The system was subsequently redesigned (IMDER-II) to eliminate firm-specific data and introduce aggregation safeguards — notably, the requirement that data relate to at least five undertakings and that no single undertaking account for more than 25% of the total.7 Combined with contextual factors such as pandemic-related supply chain disruptions, the accessibility of reports to broader market participants, and the involvement of an independent third-party data provider, the Authority concluded that the revised system could benefit from exemption.8

3.     Market Context Matters: Regulation, Structure and Transparency

Structural safeguards alone do not determine the outcome. The Authority assesses them alongside broader contextual factors.

Sectors characterised by homogeneous products, repeated interaction and high transparency attract particular scrutiny, as these features increase the risk of coordination. The role of sectoral regulators also becomes relevant: where similar information is already published by public authorities, the analysis shifts from whether the information is formally public to whether the proposed exchange mechanism materially increases market transparency through greater detail, frequency or immediacy.

The PETDER9 decision10 reflects this analytical emphasis. Various fuel, automotive LPG and lubricant data were collected by an independent company and made publicly available. The Authority compared this approach with the publication practices of the Energy Market Regulatory Authority of Türkiye (“EPDK”), which typically releases similar data with a two-to-three-month delay and at a lower level of detail. Because the proposed system would have provided market participants with more timely and granular insights than those available through 11EPDK, the Authority questioned the "public" nature of the information.

The Authority also noted that the automotive LPG distribution market displays the core features of an oligopolistic structure — concentrated, stable, with homogeneous products and long-established players. 12Despite these coordination risks, the Authority accepted that certain forms of data dissemination could be permissible, provided that detailed firm-level data and market shares are compiled and published at three-month intervals.13 Regulatory transparency, therefore, does not automatically legitimise additional information exchange; it may require stricter calibration of timing and scope.

4.     Efficiency and the Temporal Value of Information

The competitive significance of information exchange also depends on how quickly information loses its strategic value. In data-driven and technologically dynamic markets, rapid processing and continuous commercial interaction may significantly increase both the utility and the coordination potential of shared data.

At the same time, information exchange systems generate substantial efficiencies: reducing informational asymmetries, improving demand forecasting, facilitating strategic planning and lowering entry barriers. The Authority therefore engages in a balancing exercise, weighing these efficiency gains against the risk that sufficiently current and detailed data may enable coordination. Temporal safeguards — delays between data collection and dissemination — emerge as the key instrument for striking this balance.

The BKM14 decision15 illustrates this balancing exercise. BKM sought exemption for a system under which it would collect historical data from its member banks and share it via internal platforms. The Authority recognised a range of benefits: consolidated data would enable undertakings to better understand market size, supply-demand conditions and competitor positioning, thereby supporting more effective competition and reducing informational barriers for new entrants.16

Given that the system involved extensive data coverage, firm-level information and continuous operation, the Authority subjected it to careful scrutiny. Ultimately, it concluded that concerns regarding data currency could be mitigated by requiring a minimum three-month delay before disclosure — particularly for merchant-level data expressed in volume, transaction value and turnover.17 This solution preserves the efficiency gains of information exchange while curtailing its coordination potential through temporal safeguards.

5.     Conclusion: A Contextual and Design-Based Framework

The TCA’s approach cannot be reduced to a single set of rigid criteria. It reflects a layered assessment in which both structural design and sector-specific dynamics play a decisive role. Several key patterns emerge from the case law:

Flexibility in dynamic sectors. In markets such as financial services, the Authority may adopt a relatively flexible stance on data granularity, including, in certain instances, the sharing of firm-level information. This flexibility is grounded in the assessment that information depreciates rapidly in such markets, limiting its capacity to sustain coordination.

Recognition of exceptional circumstances. In cases such as IMDER, the Authority appears willing to take into account exceptional market conditions — such as pandemic-related supply chain disruptions — as contributing factors in a broader assessment of whether the information exchange serves a legitimate economic function.

Emergence of baseline design standards. Despite contextual flexibility, the decisions reveal emerging baseline patterns, particularly regarding aggregation thresholds — minimum numbers of undertakings and maximum percentage contributions to the aggregated dataset. While not formally codified, these parameters increasingly function as reference points for structuring compliant information exchange mechanisms.

No automatic prohibition, even in high-risk markets. The PETDER decision demonstrates that even in markets explicitly characterised as prone to coordination, the Authority does not adopt a purely prohibitive stance. Information exchange may be justified where it is sufficiently constrained — reflecting a broader policy of preserving informational efficiencies while preventing their transformation into coordination tools.

Taken together, these elements suggest that the Authority’s approach is best understood as a calibrated framework in which similar types of information may be treated differently depending on how they are structured, how quickly they lose their strategic value, and the broader market conditions in which they are exchanged.
