Competition Law And Competition Concerns In Resilience Monopolies

1. Introduction

“Resilience monopoly” is not a traditional statutory category in competition law. It is better understood as a modern analytical concept describing a situation in which one undertaking, or a very small group of undertakings, obtains durable control over the infrastructure, inputs, networks, technology, capacity, data, or supply channels that a market depends upon to continue functioning during disruption.

Resilience refers to the ability of a market or supply system to continue meeting demand when it faces shocks such as supply interruptions, technological failures, natural disasters, financial stress, geopolitical disruption, sudden demand increases, or the failure of an important supplier.

Competition law becomes relevant when resilience depends excessively on one dominant undertaking. Recent scholarship on competition and resilience emphasizes that market concentration can sometimes increase efficiency or permit investment in reliability, but it can also create single points of failure, bottlenecks, foreclosure risks, shortages, reduced choice, and vulnerability to cascading disruption.

A resilience monopoly therefore raises a central competition-policy question:

Does concentration make the market more capable of surviving disruption, or does it make the entire market dependent upon one powerful undertaking?

The answer depends on market structure, barriers to entry, substitutability, capacity, access to critical infrastructure, vertical integration, incentives to invest, and the availability of alternative suppliers.

2. Meaning of a Resilience Monopoly

A resilience monopoly can arise where an undertaking controls something that other businesses require not merely to compete normally, but also to continue operating when market conditions deteriorate.

Examples can include control over:

essential transport or logistics infrastructure;

telecommunications networks;

cloud or digital infrastructure;

payment systems;

critical databases;

electricity or energy networks;

strategically important components;

manufacturing capacity;

distribution channels;

essential intellectual property;

repair and maintenance ecosystems; and

indispensable upstream inputs.

The concern is particularly significant where competitors cannot reasonably reproduce the relevant resource.

For example, suppose Firm A controls the only economically practical infrastructure through which several downstream businesses can deliver their services. In ordinary circumstances, Firm A may already possess substantial market power. During a disruption, however, competitors may become even more dependent on that infrastructure.

Firm A may consequently acquire what can be described as resilience-based market power.

3. Resilience and Market Power

Competition law normally examines market power by considering factors such as market shares, entry barriers, substitutes, customer switching, network effects, capacity constraints and countervailing buyer power.

Resilience analysis adds another dimension.

A firm might become especially powerful because alternative suppliers are incapable of absorbing demand when disruption occurs.

Consider a market containing four suppliers. On paper, the market may appear reasonably diversified. However, if three suppliers depend upon infrastructure owned by the fourth supplier, the apparent diversity may disguise a structural bottleneck.

Accordingly, competition authorities examining resilience should consider not only:

“How many competitors exist?”

but also:

“How independent are those competitors from one another?”

True competitive resilience generally requires independent alternatives rather than merely several businesses sharing the same critical dependency.

4. Single Points of Failure

One of the most important concerns associated with resilience monopolies is the creation of a single point of failure.

Suppose a market depends upon one supplier for a critical component. If that supplier experiences a serious interruption, downstream production may stop across the market.

Competition law traditionally focuses on matters such as:

prices;

output;

quality;

innovation; and

consumer choice.

Resilience analysis adds another potential consequence:

the probability and economic impact of supply disruption.

Modern antitrust scholarship argues that mergers and concentration can increase risk where disruption to one important undertaking cascades through its customers and interconnected markets. Shortages and interruptions can themselves reduce output and consumer choice while increasing prices.

5. Entry Barriers and Resilience

Resilience monopolies can become particularly durable where new suppliers cannot enter quickly.

Entry barriers may include:

enormous capital requirements;

exclusive contracts;

network effects;

regulatory licences;

access to infrastructure;

intellectual-property rights;

proprietary technical standards;

switching costs;

control of data;

long construction periods; and

economies of scale.

Ordinary entry that might eventually constrain a monopolist may provide little protection during an immediate crisis.

For example, constructing another port, semiconductor fabrication facility, telecommunications network or major logistics infrastructure may require years.

Therefore, time-to-entry can be particularly important when analysing resilience-related market power.

6. Essential Facilities and Resilience Monopolies

The essential-facilities concept provides one useful historical framework.

An essential facility generally refers to infrastructure controlled by a dominant undertaking that competitors cannot practically or reasonably duplicate and to which access may be necessary for effective competition.

Potential modern examples include certain:

transport terminals;

telecommunications infrastructure;

energy grids;

payment networks;

digital platforms;

databases;

cloud infrastructure; and

logistics facilities.

However, competition law does not automatically require a successful undertaking to share its property with competitors. Compulsory-access intervention has generally been treated cautiously, particularly in US law.

The relationship between essential facilities and resilience is nevertheless important because a market can become fragile where numerous competitors depend on one bottleneck.

7. Case Law 1 — United States v. Terminal Railroad Association of St. Louis

224 U.S. 383 (1912)

This is one of the foundational American cases associated with bottleneck infrastructure.

A group of railroads obtained control over important terminal facilities and river crossings necessary for railway traffic entering St. Louis. Because geographic and practical conditions made those facilities extremely important to competing railroads, control of the infrastructure created substantial competitive concerns.

The Supreme Court required arrangements that allowed access on reasonable and non-discriminatory terms.

Importance for Resilience Monopolies

The case demonstrates how control over critical infrastructure can produce structural dependence.

Where numerous businesses rely upon one infrastructure provider, the infrastructure operator can potentially:

restrict access;

discriminate between competitors;

raise costs;

reduce competitive independence; or

become a system-wide point of vulnerability.

The case remains useful when considering modern infrastructure bottlenecks.

8. Case Law 2 — MCI Communications Corp. v. AT&T

708 F.2d 1081 (7th Cir. 1983)

MCI challenged conduct involving telecommunications infrastructure controlled by AT&T.

The decision became particularly influential in American discussions of the essential-facilities doctrine.

The court identified considerations including:

control of an essential facility by a monopolist;

competitors' practical inability reasonably to duplicate the facility;

denial of access; and

feasibility of providing access.

Resilience Significance

Telecommunications networks illustrate the connection between competition and resilience particularly clearly.

If independent service providers depend upon infrastructure controlled by a dominant competitor, a disruption or discriminatory restriction at the infrastructure level can affect competition throughout downstream markets.

The decision therefore demonstrates how infrastructure control can convert ordinary market power into broader ecosystem dependency.

9. Case Law 3 — Verizon Communications Inc. v. Law Offices of Curtis V. Trinko

540 U.S. 398 (2004)

Trinko is important because it demonstrates the limits of compulsory dealing under US antitrust law.

The Supreme Court emphasized that, as a general principle, even monopolists ordinarily have considerable freedom to decide with whom they deal. The Court was reluctant to expand antitrust duties requiring dominant businesses to assist competitors, particularly where an existing regulatory structure addressed access.

Importance for Resilience Analysis

A resilience monopoly does not automatically produce an antitrust obligation to share infrastructure.

Competition authorities and courts must consider the potential consequences of intervention.

Overly broad compulsory-access obligations can potentially:

weaken investment incentives;

discourage development of infrastructure;

require courts or authorities to regulate commercial relationships continuously; and

reduce incentives for competitors to develop alternative infrastructure.

Trinko therefore represents an important counterweight to aggressive essential-facilities theories.

10. Case Law 4 — Aspen Skiing Co. v. Aspen Highlands Skiing Corp.

472 U.S. 585 (1985)

Aspen Skiing concerned a dominant ski operator's termination of a previously existing cooperative arrangement involving a multi-area ski ticket.

The Supreme Court found circumstances supporting monopolization liability.

The case became an important authority concerning exceptional situations in which exclusionary refusal-to-deal conduct by a monopolist may violate competition law.

Connection With Resilience Monopolies

The broader lesson is relevant where a dominant undertaking controls access necessary for another undertaking to remain competitively viable.

A resilience concern could emerge where a dominant supplier terminates established access to:

infrastructure;

interoperability;

distribution;

maintenance;

critical inputs; or

network connections,

and competitors cannot reasonably replace that access.

Aspen Skiing does not establish a general duty to supply competitors, but it demonstrates that refusal-to-deal conduct can become competition-law relevant in exceptional circumstances.

11. Case Law 5 — Commercial Solvents Corp. v. Commission

Joined Cases 6/73 and 7/73

Commercial Solvents is an important European competition-law decision involving a dominant supplier of an upstream raw material.

The undertaking decided to enter a downstream market and stopped supplying an existing downstream customer.

The European courts treated the conduct as capable of constituting an abuse of dominance.

Resilience Significance

The case is highly relevant to vertically integrated resilience monopolies.

Suppose a company controls an indispensable upstream input while simultaneously competing downstream.

It could potentially strengthen its downstream position by:

withholding the input;

reducing quantities;

delaying deliveries;

discriminating between customers; or

imposing disadvantageous conditions.

During shortages, this power may become considerably stronger.

Resilience analysis therefore examines whether upstream concentration leaves downstream competitors with genuine alternative sources.

12. Case Law 6 — Bronner v. Mediaprint

Case C-7/97

Oscar Bronner concerned access to a nationwide newspaper home-delivery system controlled by a major publisher.

The Court of Justice adopted a demanding approach toward compulsory access.

Among other considerations, the requested facility had to be genuinely indispensable rather than merely more convenient or commercially attractive.

Importance

Bronner prevents the concept of resilience from becoming an unlimited justification for forced access.

A competitor normally cannot establish an abuse merely by arguing:

“Using the dominant firm's system would make my business safer or cheaper.”

The absence of access must satisfy demanding legal requirements.

The decision therefore protects the distinction between genuine structural dependence and ordinary commercial disadvantage.

13. Case Law 7 — IMS Health GmbH & Co. OHG v. NDC Health GmbH

Case C-418/01

IMS Health involved access to a copyrighted structure used in the pharmaceutical-sales information sector.

The dispute concerned circumstances in which refusal to license intellectual property by a dominant undertaking could amount to abuse.

The Court maintained a restrictive approach and connected intervention with exceptional circumstances.

Relevance to Resilience Monopolies

Modern resilience bottlenecks do not necessarily involve physical infrastructure.

They may involve:

data structures;

software interfaces;

technical standards;

databases;

intellectual property; or

interoperability systems.

IMS Health therefore demonstrates that control over intangible infrastructure may also create competitive dependency.

14. Case Law 8 — Microsoft Corp. v. Commission

Case T-201/04

The Microsoft litigation concerned, among other matters, interoperability information required by competing work-group server operating systems.

European competition authorities concluded that Microsoft's conduct involving interoperability information constituted an abuse of dominance, and the General Court substantially upheld the Commission's decision.

Resilience Importance

Digital markets can develop resilience monopolies through interoperability dependence.

Where numerous services depend upon one technological ecosystem, exclusion at an interoperability layer may prevent competing systems from developing into meaningful alternatives.

That can produce both:

competition concentration and
operational concentration.

A competitive ecosystem containing interoperable alternatives may provide greater redundancy if one provider fails or changes its conditions.

15. Vertical Integration and Resilience

Vertical integration presents one of the hardest questions in this field.

Suppose an upstream component producer merges with an important downstream manufacturer.

Integration may potentially improve resilience because the combined undertaking can coordinate:

inventory;

investment;

production;

logistics;

emergency capacity; and

long-term planning.

Recent resilience scholarship therefore recognizes that vertical integration can sometimes reduce supply risk.

However, the opposite can also happen in markets with weak competition.

The integrated undertaking may engage in input foreclosure, making an important input unavailable or more expensive for downstream competitors.

Alternatively, it may engage in customer foreclosure, weakening competing upstream suppliers.

Research on resilience and competition therefore treats vertical integration as context-dependent rather than automatically beneficial or harmful.

16. Horizontal Mergers and Resilience

Suppose five independent producers become two after successive mergers.

Even where the merged businesses obtain greater scale, the reduction in independent production centres can matter during disruption.

Potential concerns include:

fewer alternative suppliers;

correlated production systems;

reduced spare capacity;

geographic concentration;

common technology failures;

consolidated inventories; and

greater consequences if one undertaking fails.

A merger analysis concerned with resilience can therefore investigate not merely the merged firm's normal market share but whether the transaction removes an independent fallback supplier.

This is especially important in bottleneck markets and markets where interruptions can cascade into downstream sectors.

17. Capacity Withholding

A resilience monopolist may also possess the ability to restrict available capacity.

A dominant undertaking might have incentives to maintain lower output where scarcity increases margins.

During periods of disruption, withholding capacity can have especially serious consequences because customers have fewer alternatives.

Competition authorities may therefore examine:

unused capacity;

production reductions;

strategic shutdowns;

allocation systems;

discriminatory supply decisions; and

contractual restrictions preventing capacity expansion.

The important legal question remains whether particular conduct constitutes exclusionary or otherwise prohibited anticompetitive behaviour under the applicable competition regime.

18. Resilience and Cartels

Businesses may sometimes argue that cooperation is necessary during emergencies.

Certain cooperation can genuinely improve resilience—for example, limited arrangements directed toward maintaining production or distribution during extraordinary shortages.

But resilience cannot simply become a justification for:

price fixing;

market allocation;

customer allocation;

output restriction; or

coordination extending beyond what is necessary.

Indeed, scholarship examining resilience points out that cartel-related output reduction can itself weaken resilience because lower output leaves the economy less capable of responding to unexpected demand or supply shocks.

19. Digital Resilience Monopolies

The concept has particular significance in digital markets.

A digital ecosystem may depend heavily upon one provider of:

cloud computing;

operating systems;

app distribution;

identity infrastructure;

payment processing;

search infrastructure;

cybersecurity services;

data storage; or

artificial-intelligence infrastructure.

Strong network effects and switching costs can make duplication difficult.

Consequently, the failure or exclusionary conduct of one provider could potentially affect thousands of dependent businesses simultaneously.

Competition analysis therefore increasingly needs to understand ecosystem dependency, rather than viewing every digital service as an isolated product.

20. Network Effects

Network effects can reinforce resilience monopolies.

A platform becomes more valuable as more participants use it.

This can create a cycle:

More users → greater platform value → more businesses join → switching becomes harder → market power increases.

Once the network becomes critical infrastructure, customers may hesitate to adopt alternatives even where alternatives technically exist.

Accordingly, competition authorities may examine whether interoperability, portability or other mechanisms can preserve contestability without destroying legitimate investment incentives.

21. Diversification Versus Concentration

Resilience and productive efficiency do not always point in the same direction.

A concentrated system can sometimes achieve:

economies of scale;

sophisticated infrastructure;

coordinated inventories;

better quality control; and

substantial investment in backup systems.

A diversified competitive system may instead provide:

independent suppliers;

technological diversity;

geographic diversification;

alternative capacity;

competitive innovation; and

reduced dependence upon one undertaking.

Recent economic analysis stresses this tension: concentration can sometimes internalize certain risks, while competition among independent suppliers may generate greater aggregate investment in reliability and alternative capacity.

Competition law therefore should not mechanically assume that either concentration or fragmentation always maximizes resilience.

22. Resilience as a Merger-Efficiency Argument

Companies may argue that a merger improves resilience by allowing them to:

diversify supply;

maintain larger inventories;

coordinate logistics;

finance backup capacity;

strengthen cybersecurity;

improve geographic diversification; or

survive future shocks.

Such claims require careful examination.

Authorities should distinguish between resilience improvements that genuinely require the merger and improvements that could reasonably be achieved through less restrictive arrangements.

The central issue is whether claimed resilience benefits outweigh or otherwise alter the competitive assessment under the relevant merger law.

23. Resilience-Washing

A further concern is resilience-washing.

This can occur when businesses describe anticompetitive arrangements as necessary for resilience without demonstrating a genuine connection.

For example, firms should not ordinarily be permitted to justify market allocation merely by saying that coordination makes the industry “more stable.”

Authorities should ask:

What specific disruption is being addressed?

Is the arrangement genuinely capable of reducing that risk?

Is the restriction necessary?

Are less restrictive alternatives available?

How long will the arrangement operate?

Does it preserve independent decision-making where possible?

This prevents resilience from becoming a broad exemption from competition law.

24. Innovation Concerns

Resilience monopolies can also affect innovation.

A dominant undertaking controlling a critical ecosystem may have fewer competitive incentives to develop alternative technologies.

Competitors may also struggle to introduce innovations if they cannot obtain:

infrastructure access;

interoperability;

necessary data;

distribution;

inputs; or

customers.

Conversely, intervention that goes too far can reduce the expected return from developing expensive infrastructure.

Competition law therefore faces a balancing problem between protecting contestability and preserving legitimate investment incentives.

25. Measuring Resilience in Competition Analysis

Competition authorities considering resilience could examine indicators including:

Supplier concentration

How many genuinely independent suppliers exist?

Spare capacity

Could alternative suppliers increase production after a disruption?

Switching time

How quickly could customers change suppliers?

Geographic concentration

Are production facilities concentrated in the same area?

Infrastructure dependency

Do apparently competing businesses rely upon the same infrastructure?

Technological diversity

Do competitors use independent technologies or the same underlying system?

Inventory

Are sufficient stocks available to absorb temporary disruption?

Entry time

Could a new competitor enter before shortages become serious?

Interoperability

Can customers realistically move between systems?

Vertical dependencies

Does one undertaking control critical upstream inputs?

These factors provide a broader picture than market shares alone.

26. Competition Law Remedies

Where an actual competition-law infringement is established, possible remedies—depending upon the jurisdiction and legal basis—may include:

cessation of exclusionary conduct;

non-discriminatory access obligations;

interoperability requirements;

modification of exclusivity arrangements;

supply obligations in exceptional circumstances;

divestiture in merger cases;

prohibition of anticompetitive mergers;

behavioural commitments;

structural remedies; and

penalties for established infringements.

The remedy should correspond to the identified competitive harm.

Competition law should not simply redesign an industry because regulators prefer greater redundancy.

27. Relationship With Sector Regulation

Competition law cannot solve every resilience problem.

Critical industries may require dedicated regulation governing matters such as:

minimum inventories;

backup infrastructure;

cybersecurity;

emergency capacity;

business continuity;

interoperability;

disaster recovery; and

supply diversification.

Competition law and resilience regulation therefore perform different but complementary functions.

Competition law primarily protects competitive market structures and prevents anticompetitive conduct.

Sector regulation can impose affirmative resilience requirements even where no competition-law violation exists.

Recent scholarship describes such dedicated rules as forms of resilience regulation.

28. Broader Legal Significance

The idea of resilience monopolies demonstrates that monopoly power is not concerned solely with whether consumers pay higher prices today.

Concentration can influence whether markets remain functional tomorrow.

A highly concentrated market may appear efficient during normal conditions while containing hidden dependencies that become visible only after disruption.

Accordingly, resilience analysis expands attention from:

Price → Output → Quality → Innovation

toward:

Price → Output → Quality → Innovation → Reliability → Redundancy → Recovery capacity.

This does not mean resilience replaces traditional competition analysis. Rather, resilience can provide additional evidence about how concentration or exclusion affects output, consumer choice and long-term competitive structure.

29. Key Competition Concerns

The principal competition concerns associated with resilience monopolies can therefore be summarized as:

Single points of failure created by excessive concentration.

Bottleneck control over indispensable infrastructure.

Input foreclosure against downstream competitors.

Customer foreclosure against upstream competitors.

Discriminatory access to critical infrastructure.

High switching costs preventing diversification.

Network effects reinforcing entrenched dominance.

Reduced independent capacity following consolidation.

Strategic capacity withholding during shortages.

Reduced innovation in alternative technologies.

Resilience-washing of restrictive agreements.

Systemic cascading effects when a dominant supplier fails.

30. Conclusion

“Resilience monopoly” is best treated as an analytical concept rather than a separate legal offence. It describes circumstances in which market concentration and control over critical resources create dependence that may become especially significant during economic or technological disruption.

The central competition-law challenge is that resilience and competition can interact in both directions.

Concentration can sometimes finance stronger infrastructure, improve coordination and reduce particular supply risks. At the same time, excessive concentration can eliminate independent suppliers, create bottlenecks and turn one undertaking into a system-wide point of failure. Contemporary scholarship therefore cautions against assuming either that monopoly automatically produces resilience or that fragmentation automatically produces security.

The case law illustrates both sides of this problem. Terminal Railroad and MCI v. AT&T demonstrate concerns surrounding bottleneck infrastructure; Aspen Skiing addresses exceptional exclusionary refusal-to-deal conduct; Commercial Solvents illustrates foreclosure through control of an upstream input; Bronner and Trinko impose important limits on compulsory-access theories; while IMS Health and Microsoft demonstrate how similar issues can arise around intellectual property, data and interoperability.

For modern competition policy, the most useful question is therefore not simply whether a market is concentrated. Authorities should examine whether there are genuinely independent alternatives, sufficient spare capacity, realistic switching possibilities, interoperable systems and viable routes of entry.

A market may contain several nominal competitors yet remain structurally fragile if all of them depend upon the same bottleneck. Conversely, a concentrated market is not automatically unlawful merely because disruption would be economically important.

The competition-law objective is to distinguish legitimate scale and resilience-enhancing investment from market structures or exclusionary practices that create unnecessary dependence, suppress competitive alternatives and magnify the consequences of future disruption.
