In 2017, the European Commission fined Google 2.4 billion euros for abusing its dominant position in online shopping search. In 2018, it fined Google 4.3 billion euros for bundling its apps with Android. In 2019, it fined Google 1.5 billion euros for restricting competition in online advertising. Three fines, three separate investigations, over eight billion euros - from a single competition authority in Brussels.

Google is not a European company. Its headquarters are in Mountain View, California. Its founders are American. Its shareholders are primarily American institutional investors. Yet it paid those fines, modified its products globally in response to European requirements, and dispatched its most senior executives to Brussels for negotiations that lasted years.

This is EU competition policy in action. Understanding why it works - why companies headquartered in California comply with decisions made in Brussels - requires understanding both the legal architecture of European competition law and the economic logic that makes compliance rational even for the world's most powerful technology companies.

EU competition policy rests on two articles of the Treaty on the Functioning of the European Union. Article 101 prohibits agreements between companies that restrict competition - cartels, price-fixing arrangements, market allocation schemes. Article 102 prohibits the abuse of a dominant market position.

These provisions have been in place since the Treaty of Rome in 1957. What has changed over the decades is their interpretation, their enforcement, and the resources dedicated to applying them.

The European Commission's Directorate-General for Competition - DG COMP - is the primary enforcement body. It investigates, prosecutes, and decides competition cases for the entire EU. Unlike the American system, where antitrust enforcement is split between the Department of Justice and the Federal Trade Commission and must ultimately be decided by courts, the Commission acts as investigator, prosecutor, and first-instance decision-maker simultaneously. Companies can appeal to the General Court and ultimately the Court of Justice of the EU - but the Commission's initial decision stands pending appeal, and appeals take years.

The fines available under EU competition law are substantial: up to 10 percent of a company's global annual turnover. For a company the size of Google or Meta, that is a number measured in billions. The Commission has shown willingness to impose fines at that scale when it concludes that violations are serious and repeated.

The jurisdictional reach of EU competition law is grounded in the effects doctrine: the Commission can investigate and sanction conduct that occurs anywhere in the world if it has effects on competition within the European market.

A cartel formed in Japan between Japanese companies, fixing prices for products sold globally, is subject to EU competition enforcement if European buyers pay inflated prices as a result. A merger between two American companies is subject to EU review if the combined entity would have significant market share in Europe. An American technology platform abusing its dominant position affects European users and European businesses - and is therefore within scope.

This extraterritorial reach is not unique to Europe - American antitrust law operates on similar principles. What distinguishes the EU is the scale of its market, the consistency of its enforcement, and the willingness of successive Commissioners for Competition to take on the world's largest companies in high-profile, resource-intensive cases.

For American companies, the calculation is straightforward: the EU is the world's largest single market by most measures, and access to that market is worth modifying business practices to maintain. Compliance with EU competition requirements is expensive. Losing EU market access would be more expensive.

The traditional competition policy toolkit - investigation, fine, appeal, modification - is slow. A major competition investigation takes five to ten years from opening to final judgment. By the time the Commission concludes that a technology platform has abused its dominant position, the market may have changed entirely.

The Digital Markets Act, which came into force in 2022 and began applying to designated gatekeepers in 2023, represents a different approach. Rather than waiting for abuse to occur and then investigating it, the DMA designates platforms above certain size thresholds as gatekeepers and imposes ex ante obligations - requirements that apply continuously, regardless of whether specific abuse has been proven.

Gatekeepers must allow interoperability with competing services. They cannot self-preference their own products in rankings. They cannot require businesses using their platforms to use their payment systems exclusively. They must allow users to uninstall pre-installed apps. They must share certain data with business users and competitors.

The Commission does not need to prove that a specific act harmed competition. It needs only to show that the gatekeeper has failed to comply with its obligations. This shifts the enforcement burden significantly and dramatically reduces the time from violation to consequence.

Apple, Alphabet, Meta, Amazon, Microsoft, and ByteDance have all been designated as gatekeepers. Each faces ongoing compliance obligations and monitoring by the Commission. The DMA is not competition law in the traditional sense - it is structural regulation of market architecture, using competition policy logic.

Alongside cartel and abuse-of-dominance enforcement, the Commission reviews mergers that meet certain size thresholds. Companies planning a significant acquisition must notify the Commission before completing the transaction if the combined entity would have sufficient European market presence.

The Commission can approve a merger unconditionally, approve it subject to conditions - typically requiring the sale of certain assets or businesses - or prohibit it entirely. Prohibition is rare but not unprecedented. The most high-profile recent case was the Commission's blocking of the Siemens-Alstom railway merger in 2019, which was controversial because both companies were European and the stated rationale was partly to create a European champion capable of competing with Chinese state-backed competitors.

The Siemens-Alstom decision illustrates a tension in EU competition policy that has become more acute in the geopolitical context of the 2020s. Traditional competition policy prioritises consumer welfare - prices, choice, quality. Industrial policy prioritises European strategic capacity. When these objectives conflict, competition policy has traditionally won. Whether that will remain true as European strategic autonomy concerns intensify is an open question.

The most common misreading is to treat EU competition enforcement as protectionism - a way of handicapping successful American companies in favour of less competitive European ones. This misreads both the motivation and the mechanism.

EU competition enforcement has fined European companies as heavily as American ones. Volkswagen, Airbus, pharmaceutical companies, banks, commodity traders - the case history is not one of systematically targeting foreign firms. It is one of systematically targeting dominant firms, regardless of nationality.

The second misreading is to underestimate how much EU competition decisions shape global business practices. When Google modified its Android agreements in response to EU requirements, it modified them globally - not just for European users. When Apple changed its App Store rules under DMA pressure, the changes affected developers worldwide. The Brussels Effect operates in competition policy as it does in data protection and product regulation.

For American executives and investors, the practical implication is that EU competition policy is a material business risk that requires active management, not a background regulatory noise. Companies with significant European market presence, dominant market positions in any major sector, or pending European acquisitions need specialist advice and ongoing monitoring - not as a compliance checkbox but as a strategic function.

EU competition policy is the most consequential antitrust system in the world not because it is the toughest, but because the market it protects is large enough that no company can afford to lose access to it.

Friday's EuroTasteDaily Review examines where EU and US competition law are converging, where they are diverging, and what the gap between them means for companies operating across the Atlantic. The transatlantic regulatory divergence is not just a legal question - it is increasingly a strategic one.
