Short answer
An exchange restricts competition by object only when its content, objectives, and economic and legal context show that it is, by its very nature, sufficiently harmful to competition. The clearest case is a confidential exchange of strategic information about future prices, quantities, capacity, or another important competitive parameter that removes uncertainty about how competitors intend to behave. If that classification is established, an authority need not prove actual market effects.
The label is deliberately narrow. If the exchange does not itself reveal the required degree of harm—because the information is genuinely public, aggregated, historical, necessary for legitimate cooperation, or ambiguous in its competitive significance—its actual or likely effects must be assessed. That assessment compares competition with the exchange against the conditions that would probably exist without it. The information's age, detail, frequency, coverage, and usefulness are relevant, as are market concentration, entry barriers, transparency, and credible pro-competitive explanations. No single factor is conclusive.
Article 101 creates two alternative routes
Article 101(1) of the Treaty on the Functioning of the European Union (TFEU) applies to agreements, decisions by associations, and concerted practices that may affect trade between Member States:
The following shall be prohibited as incompatible with the internal market: all agreements between undertakings, decisions by associations of undertakings and concerted practices which may affect trade between Member States and which have as their object or effect the prevention, restriction or distortion of competition within the internal market, and in particular those which: —
“Object” and “effect” are alternative legal routes, not cumulative requirements. The object inquiry comes first. If the practice is sufficiently harmful by its nature, effects need not be proved. If it is not, the authority must establish appreciable restrictive effects. Calling an exchange commercially sensitive does not by itself complete either route.
The Court of Justice has repeatedly stressed that “by object” must be interpreted restrictively. In Budapest Bank, Case C-228/18, the Court explained why:
The concept of restriction of competition ‘by object’ can be applied only to certain types of coordination between undertakings which reveal a sufficient degree of harm to competition for it to be found that there is no need to examine their effects ... —
The authority must therefore identify the precise reason why the exchange belongs to an inherently harmful form of coordination. It cannot use the object label simply because an effects case would be difficult.
When is an information exchange harmful by its object?
Three connected questions control the classification.
First, what information was exchanged? Future prices and quantities are the clearest danger. The Commission's non-binding 2023 Horizontal Cooperation Guidelines also identify current or future pricing, capacity, commercial strategy, demand forecasts, future sales, and future product characteristics as categories that have been treated as object restrictions in the relevant context. Information can be strategic even if it concerns only one price component or present or past data: the question is whether competitors can combine it with other knowledge to infer future strategy.
Second, what uncertainty did the exchange remove? Competition normally requires each undertaking to determine its conduct independently while remaining uncertain about competitors' future choices. In T-Mobile Netherlands, Case C-8/08, a single meeting concerned the reduction of dealer remuneration. The Court stated:
An exchange of information between competitors is tainted with an anti-competitive object if the exchange is capable of removing uncertainties concerning the intended conduct of the participating undertakings. —
That test does not mean that every reduction in uncertainty is unlawful. Market transparency can intensify competition. The concern is coordination that replaces competitive uncertainty with knowledge about rivals' intended conduct or enables a common course of action.
Third, does the context make the exchange inherently harmful? The assessment includes the nature of the product, how the market functions, its structure, and the exchange's objective aims. Concentration and entry barriers can make strategic disclosure more dangerous. Frequency matters, but one contact can suffice. Public disclosure can also be problematic where it operates as a signal or focal point rather than a genuine communication to customers or investors.
What the 2024 banking judgment adds
The Court of Justice's most focused recent treatment is Banco BPN/BIC Português, Case C-298/22. Competing banks reciprocally exchanged detailed current and future credit spreads, risk variables, and individual production figures in concentrated markets with entry barriers.
The Court distinguished useful market transparency from removal of competitive uncertainty. It held that a standalone exchange may be harmful by object where confidential strategic information reveals intended conduct on a parameter of competition. In particular:
an exchange of information may be regarded as constituting a form of coordination between undertakings which, by its very nature, is harmful to the proper functioning of normal competition ... where that exchange makes it possible to remove such uncertainty. To that end, it is sufficient for the information exchanged to be, first, confidential and, second, strategic. —
The Court regarded the future credit spreads as strategic because they revealed intended pricing conduct. It also explained that past production volumes, viewed alone, were less clearly harmful; their significance depended on whether they could be combined with the other exchanged information to reveal future intentions. This is a useful warning against classifying every field in a shared dataset identically.
The same judgment confirms several practical points. A single exchange can be enough. Information need only concern one competitive parameter, not the entire final price. Disclosure shortly before publication can still remove uncertainty sooner than normal market operation would. And where an object restriction is properly established, it is unnecessary to show that recipients changed their conduct or even actually used the information.
When must restrictive effects be examined?
An effects analysis is required when the content, objectives, and context do not establish sufficient inherent harm. In Budapest Bank, the evidence about a common interchange fee was ambivalent: the arrangement might have reduced one form of competition while intensifying another, and the available experience did not justify dispensing with effects analysis. The Court required sufficiently reliable and robust experience before treating the arrangement as harmful by its nature.
The effects inquiry is not limited to observed price changes. It compares the actual or likely competitive conditions with the counterfactual situation absent the exchange. Relevant parameters include price, output, quality, variety, and innovation. The analysis should consider:
- whether the information is individualised or aggregated, confidential or readily public, current or old;
- whether it concerns intended conduct or merely market facts that do not reveal strategy;
- the frequency and duration of exchanges and how much additional transparency they create;
- participants' combined market position, concentration, stability, entry barriers, and outsider constraints;
- whether the exchange enables coordination, monitoring, retaliation, or foreclosure; and
- demonstrated, exchange-specific benefits and whether less restrictive data could achieve them.
Actual effects are not always the only permissible proof: likely effects may be enough where the legal test is satisfied. But the authority must provide evidence of appreciable harm under the counterfactual, rather than infer effects merely from contact between competitors.
Do efficiency claims prevent an object finding?
Credible pro-competitive effects form part of the context. In HSBC Holdings, Case C-883/19 P, the Court held that they must be demonstrated, relevant, specifically related to the exchange, and significant enough to create reasonable doubt about its harmful nature. A vague claim that added transparency helps customers is insufficient.
This contextual inquiry is distinct from Article 101(3). Even a restriction falling within Article 101(1) may qualify for exemption only if it produces efficiencies, gives consumers a fair share, imposes no non-indispensable restrictions, and does not eliminate competition for a substantial part of the products concerned. Exchanges that implement price fixing, market sharing, output limits, or another cartel are very unlikely to meet those conditions.
Practical questions before competitors share data
Before an exchange, participants should ask:
- Is each data field necessary for a defined legitimate purpose?
- Does it disclose future pricing, quantities, capacity, customers, product plans, or strategic reactions?
- Is the information already genuinely accessible on equal terms, or merely described as public?
- Can individual firms be identified, directly or by combining fields?
- Would aggregation, ageing, wider intervals, lower frequency, or a trustee achieve the same purpose?
- Who can access raw data, and can commercial teams use it?
- Does the exchange go beyond a regulatory obligation or what is objectively necessary for a lawful cooperation?
- If sensitive information is unexpectedly disclosed, is there a clear objection, departure, and written record of distancing?
Clean teams and trustees reduce risk only when their design prevents competitors from receiving usable individual strategic information. They do not make an unnecessary exchange lawful by themselves.
Conclusion
An information exchange restricts competition by object when a strict examination of its content, objectives, and context shows that it is inherently harmful—most clearly where confidential strategic information removes uncertainty about competitors' intended conduct. No proof of actual effects is then required. Where that inherent harm is not established, the authority must examine actual or likely restrictive effects against a credible counterfactual. The dividing line depends on what the data reveals and how the market works, not on labels such as “benchmarking”, “public”, or “data pool”.
