Loyalty Program Foreclosure in Competition Law

1. Introduction

Loyalty Program Foreclosure occurs when a firm uses a customer-loyalty mechanism—such as points, rebates, rewards, exclusive benefits, cashback, preferential pricing, membership tiers, or accumulated purchase incentives—to make customers substantially less willing or able to purchase from competing firms.

A loyalty program is not inherently anti-competitive. It can produce legitimate benefits such as encouraging repeat purchases, reducing transaction costs, improving customer retention, and generating efficiencies. The competition-law concern arises particularly where a dominant undertaking structures the program so that customers are economically induced to obtain all or most of their requirements from it, thereby foreclosing actual or potential competitors.

In China, this issue is principally analysed through the rules on abuse of dominant market position, particularly the prohibition on unjustified exclusive dealing, discriminatory transaction terms, and other forms of abusive conduct. Article 17 of the former Anti-Monopoly Law expressly prohibited a dominant undertaking, without justifiable reasons, from requiring trading counterparts to deal exclusively with it or designated undertakings.

China's Tetra Pak decision is particularly important because it was the first major Chinese enforcement decision to deal expressly with loyalty discounts.

2. Meaning of Loyalty Program Foreclosure

A loyalty program can create foreclosure when the economic structure of the program makes switching to a rival commercially unattractive.

Typical mechanisms include:

1. Exclusive-purchase rewards
   • Customer receives rewards only if it purchases exclusively from the dominant firm.
2. Retroactive rebates
   • Once a customer crosses a threshold, the rebate applies to previous purchases as well.
   • This can substantially increase the cost of switching.
3. Target rebates
   • Customer receives a substantial reward for reaching an individualized purchasing target.
4. Tiered loyalty programs
   • Higher purchasing levels unlock progressively greater discounts or benefits.
5. Points expiration
   • Customers may lose accumulated points if they switch to another provider.
6. Bundled loyalty benefits
   • Membership provides benefits across several products or markets.
7. Platform loyalty programs
   • A platform gives sellers or consumers preferential ranking, lower commissions, advertising credits, or other benefits for maintaining high levels of activity.
8. Ecosystem loyalty
   • Rewards are usable only within the dominant firm's ecosystem, increasing switching costs.

3. Why Loyalty Programs May Foreclose Competitors

The central economic problem is that the customer does not necessarily compare the ordinary price of competing products.

Instead, the customer compares:

Price of rival + loss of accumulated loyalty benefits

This can make an otherwise competitive rival commercially unattractive.

For example:

• Dominant firm price = ₹100
• Rival price = ₹95
• Customer has ₹10 worth of accumulated rewards with dominant firm.

The customer's effective switching cost may therefore be significant even though the rival has a lower nominal price.

The foreclosure effect becomes stronger where:

• the dominant firm's market share is high;
• customers have substantial switching costs;
• rewards are retroactive;
• thresholds are difficult to satisfy incrementally;
• customers purchase frequently;
• the rebate covers a large proportion of demand;
• competitors cannot economically compensate customers for lost benefits;
• the program covers a large portion of the market;
• network effects reinforce customer retention.

4. Legal Framework in China

A. Dominant market position

The first question is normally whether the undertaking possesses a dominant position in the relevant market.

Factors may include:

• market share;
• ability to control prices or other trading conditions;
• financial and technological strength;
• barriers to entry;
• dependence of trading counterparts;
• competitors' ability to constrain the undertaking;
• network effects and data advantages in digital markets.

A loyalty program operated by a small firm in a highly competitive market will ordinarily raise a different competition question from an identical program operated by a dominant undertaking.

B. Exclusive dealing

Where loyalty benefits effectively require customers to purchase exclusively or predominantly from the dominant undertaking, the conduct may resemble exclusive dealing.

The Chinese statutory framework has specifically addressed unjustified requirements that trading counterparts deal exclusively with the dominant undertaking or its designated parties.

The key question is therefore not simply:

"Is there a loyalty discount?"

but:

Does the loyalty mechanism materially restrict customers' ability or incentive to purchase from competing suppliers?

C. Differential treatment

A loyalty program can also raise issues of discriminatory treatment where similarly situated trading counterparts receive materially different discounts or benefits without a legitimate justification.

China's implementing rules address differences in transaction prices, quantities, discounts, payment terms and related conditions between similarly situated counterparties.

5. Important Distinction: Quantity Discounts vs Loyalty Discounts

This distinction is fundamental.

Quantity discount

A customer receives a lower price because purchasing a larger quantity generates economies of scale.

Example:

Buy 1,000 units → 5% discount
Buy 5,000 units → 10% discount

This may reflect legitimate cost savings.

Loyalty discount

The discount depends on obtaining most or all requirements from the dominant undertaking.

Example:

Buy at least 90% of your annual requirements from us → 15% rebate.

The second arrangement can make competitors' access to the customer more difficult.

The European Court of Justice has traditionally distinguished ordinary quantity discounts from loyalty rebates, while modern jurisprudence increasingly considers the actual capability of the rebate scheme to foreclose competition.

6. Forms of Foreclosure

A. Customer foreclosure

The dominant firm captures customers through rewards, leaving rivals with insufficient demand.

B. Competitor foreclosure

Competitors cannot obtain sufficient sales volume to compete effectively.

C. Entry foreclosure

A new entrant cannot build a customer base because customers are locked into the dominant firm's loyalty ecosystem.

D. Partial foreclosure

Only a portion of the market is foreclosed, but that portion may nevertheless be strategically important.

E. Ecosystem foreclosure

A loyalty scheme connects multiple markets—for example:

payment service → marketplace → delivery → cloud service → rewards.

The customer may remain within the entire ecosystem because leaving one component causes loss of benefits elsewhere.

7. At Least 6 Important Case Laws

1. Hoffmann-La Roche & Co. AG v Commission — 1979

This is one of the foundational European loyalty-rebate cases.

The Court considered fidelity rebates offered by a dominant undertaking to customers purchasing all or most of their requirements from it.

Principle

A dominant firm may abuse its position where its rebate structure induces customers to satisfy their requirements predominantly or exclusively from that firm and thereby restricts competitors' access to the market.

Relevance

The case established the traditional distinction between:

• ordinary quantity discounts; and
• loyalty/fidelity rebates.

It remains the conceptual starting point for analysing loyalty-induced foreclosure.

2. Michelin I — NV Nederlandsche Banden-Industrie Michelin v Commission, 1983

Michelin operated a system of rebates for tyre dealers.

The Court examined the structure of the rebate system and the dominant firm's position.

Principle

A rebate scheme must be assessed in the context of:

• the dominant firm's market position;
• conditions governing the rebate;
• duration;
• percentage of the market affected; and
• competitive conditions.

Importance

Michelin demonstrated that foreclosure can arise even where the customer is not formally prohibited from purchasing from competitors.

A sufficiently powerful financial incentive can itself influence customer behaviour.

3. British Airways v Commission — 2007

British Airways operated commission schemes for travel agents that rewarded agents for achieving increased sales.

The European courts examined whether the system encouraged travel agents to favour British Airways over competing airlines.

Principle

The legal concern is whether the rebate or incentive is capable of producing an exclusionary effect on competitors.

Relevance to loyalty programs

This case is particularly useful for analysing:

• sales commissions;
• performance bonuses;
• tiered incentives;
• travel-platform loyalty schemes;
• marketplace seller incentives.

The case confirmed the importance of examining the structure and economic impact of the incentive rather than merely its label.

4. Tomra Systems v Commission — 2012

Tomra supplied reverse-vending machines and used various rebate arrangements with customers.

The European courts examined whether the arrangements restricted competitors' ability to obtain customers.

Principle

A dominant undertaking does not necessarily need to foreclose the entire market.

Foreclosure of a sufficiently significant portion of demand may impair competitors' ability to compete.

Importance

Tomra is particularly relevant where:

• loyalty rewards cover only some customers;
• contracts are individually negotiated;
• thresholds differ between customers;
• the dominant undertaking uses individualized targets.

It demonstrates that the analysis focuses on the practical exclusionary capability of the scheme.

5. Intel Corp. v Commission — CJEU, 2017

Intel offered rebates to major computer manufacturers and a retailer, with the European Commission alleging that the rebates encouraged loyalty and foreclosed AMD.

The CJEU significantly developed the approach to conditional rebates.

Principle

Where the Commission relies on an economic analysis such as the as-efficient-competitor (AEC) test, the reviewing court must properly examine the undertaking's arguments concerning that analysis.

The Court therefore moved the analysis toward a more effects-oriented examination rather than automatically treating every conditional rebate as unlawful.

Importance for loyalty programs

The analysis may consider:

• coverage of the market;
• duration;
• rebate conditions;
• dominant firm's market position;
• amount of the rebate;
• competitors' ability to compete;
• economic evidence concerning foreclosure.

6. Post Danmark II — 2015

Post Danmark offered conditional and retroactive rebates to customers based on quantities of mailings.

The Court examined whether the rebate structure was capable of restricting competition.

Principle

A rebate that is not formally exclusive can nevertheless require careful examination where its structure creates loyalty-inducing effects.

The Court distinguished the scheme from a straightforward quantity rebate because the rebate depended on aggregate purchases over a period rather than merely reflecting savings associated with individual orders.

Relevance

This is highly relevant to:

• annual loyalty programs;
• volume-based membership schemes;
• accumulated points;
• year-end rebates;
• retroactive cashback programs.

8. China: Tetra Pak Loyalty Discount Case

Tetra Pak — SAIC, 2016

This is the most directly relevant Chinese case.

The State Administration for Industry and Commerce found that Tetra Pak possessed dominant positions in several relevant markets involving:

• paper-based aseptic packaging equipment;
• packaging materials; and
• technical services.

The authority found several forms of conduct, including loyalty discounts, exclusive dealing and tying. Tetra Pak was fined approximately RMB 667.7 million.

Loyalty mechanism

Tetra Pak's arrangements included forms of:

• cumulative volume discounts;
• individualized purchase requirements;
• performance-related incentives;
• warranty-related incentives.

The discount arrangements could encourage customers using Tetra Pak equipment to obtain packaging materials from Tetra Pak.

Legal importance

The case is especially significant because it represented China's first major antitrust ruling expressly addressing loyalty discounts.

The decision was analysed under the Chinese prohibition on abuse of dominance, including the provision allowing enforcement authorities to identify other forms of abusive conduct not specifically enumerated in the statute.

Competition concern

The central concern was that loyalty incentives could make it difficult for competing suppliers of packaging materials to obtain sufficient customer demand.

9. Comparative Case Table

10. Factors Used to Determine Foreclosure

A competition authority or court should examine the actual economic structure of the program.

1. Market share

The higher the dominant firm's market position, the greater the potential competitive significance.

2. Duration

A short promotional campaign may have limited effects.

A multi-year loyalty arrangement may make customer switching substantially more difficult.

3. Market coverage

Authorities examine how much of the market is effectively tied to the loyalty program.

4. Rebate magnitude

A small reward may not materially affect purchasing decisions.

A large retroactive rebate can create powerful switching incentives.

5. Threshold structure

Consider:

• 50% threshold;
• 70% threshold;
• 90% threshold;
• 100% threshold.

The closer the requirement is to exclusivity, the greater the potential foreclosure concern.

6. Retroactivity

Suppose:

90% threshold → 10% rebate on all annual purchases.

A customer approaching the threshold may have a strong incentive to purchase additional units from the dominant firm because losing the threshold would affect the entire year's purchases.

This can make the incremental cost of switching particularly significant.

11. Individualized Loyalty Targets

Individualized targets may create additional competition concerns.

Suppose Firm A tells:

• Customer X: 70% target;
• Customer Y: 80% target;
• Customer Z: 95% target.

The targets may be designed according to each customer's historical purchasing behaviour.

Such individualized schemes can potentially make competitors' entry or expansion more difficult because each customer receives a tailored incentive designed to capture a substantial proportion of its demand.

The economic literature discussing China's Tetra Pak case specifically identifies retroactive loyalty discounts and individualized volume-target discounts as important features of the scheme.

12. Digital Loyalty Programs

Modern loyalty programs can be substantially more sophisticated than traditional rebates.

Examples include:

E-commerce

• loyalty points;
• preferred seller status;
• free shipping;
• platform coupons;
• priority search placement.

Digital payments

• cashback;
• wallet rewards;
• merchant discounts;
• transaction-based points.

Airlines

• frequent-flyer points;
• status tiers;
• lounge access;
• bonus miles.

Food-delivery platforms

• subscription discounts;
• free delivery;
• restaurant-specific rewards.

Cloud ecosystems

• credits;
• volume-based discounts;
• free technical support;
• interoperability benefits.

App ecosystems

• membership benefits;
• subscription bundles;
• exclusive digital content.

The competition concern increases where loyalty benefits are interoperability-restricted and customers lose accumulated value when moving to a rival platform.

13. Loyalty Programs and Network Effects

Digital markets present an additional issue: network effects.

Assume:

More customers → more merchants → more transactions → more rewards → more customers.

A loyalty program can reinforce this cycle.

The resulting foreclosure may therefore extend beyond the immediate discount.

The dominant firm may obtain:

• more data;
• more customers;
• greater merchant participation;
• stronger network effects;
• higher switching costs;
• greater advertising value.

Consequently, competition authorities may need to assess the ecosystem effect, rather than analysing the loyalty reward in isolation.

14. Legitimate Business Justifications

A loyalty program is not automatically unlawful.

Possible legitimate justifications include:

A. Economies of scale

Higher purchase volumes may reduce average costs.

B. Administrative efficiency

A single large customer relationship can reduce transaction and servicing costs.

C. Consumer benefits

Rewards may reduce prices or improve service quality.

D. Customer acquisition

Temporary introductory rewards may enable a new business to compete against established firms.

E. Genuine investment recovery

A supplier may provide equipment or infrastructure and reasonably seek sufficient demand to recover investment.

F. Fraud prevention

Loyalty restrictions may sometimes be necessary to prevent abuse of reward systems.

The important question is whether the justification is genuine, proportionate and connected to legitimate efficiencies, rather than merely a mechanism for protecting the dominant firm's market position.

15. Loyalty Foreclosure vs Ordinary Competition

The distinction can be expressed simply:

Legitimate competition

"We give customers better prices and services because we are more efficient."

Potential loyalty foreclosure

"We give customers benefits structured so that purchasing from competitors causes them to lose substantial accumulated value."

The latter requires closer scrutiny where the firm is dominant and the arrangement has substantial exclusionary capability.

16. Economic Tests

Modern competition analysis can involve an as-efficient-competitor (AEC) test, particularly in rebate cases.

The basic question is:

Could an equally efficient competitor profitably compete for the contestable portion of the customer's demand after taking the dominant firm's rebate into account?

The precise methodology varies according to the legal system and circumstances.

Relevant economic variables include:

• effective rebate;
• contestable share;
• incremental price;
• average avoidable cost;
• average variable cost;
• duration;
• rebate threshold;
• market coverage.

The Intel judgment is particularly important because the CJEU required meaningful examination of economic evidence where such an analysis formed part of the Commission's reasoning.

17. Remedies

If loyalty-program foreclosure is established, potential remedies may include:

Behavioural remedies

• eliminate exclusivity requirements;
• redesign rebate thresholds;
• remove retroactive rebates;
• prohibit individualized exclusionary targets;
• permit customers to switch without losing unrelated benefits;
• impose transparent eligibility criteria.

Structural remedies

In exceptional cases, authorities may consider structural measures where behavioural remedies are insufficient.

Monetary penalties

Competition authorities may impose fines under applicable competition legislation.

Compliance measures

Businesses may also be required to:

• amend contracts;
• modify incentive structures;
• establish competition-compliance procedures;
• monitor sales practices.

19. Key Legal Principles

1. Loyalty programs are not inherently unlawful.
2. The dominant firm's market position is central.
3. Exclusive or predominantly exclusive purchasing incentives create heightened concern.
4. Retroactive rebates can create particularly strong switching incentives.
5. Individualized targets can increase foreclosure risks.
6. Market coverage and duration are important.
7. The analysis increasingly considers economic effects and foreclosure capability.
8. Legitimate efficiencies and objective justifications must be considered.
9. Digital loyalty schemes may create additional switching-cost and network-effect problems.
10. China's Tetra Pak decision is the principal Chinese precedent specifically concerning loyalty discounts. 

Conclusion

Loyalty Program Foreclosure occupies the boundary between legitimate customer incentives and exclusionary abuse. A loyalty scheme becomes competition-law significant when a dominant undertaking structures discounts, points, rebates, memberships or other benefits so that customers are economically discouraged from dealing with competitors and rivals are consequently deprived of an effective portion of market demand.

The most important authorities are Hoffmann-La Roche, Michelin I, British Airways, Tomra, Post Danmark II, Intel, and, for China specifically, Tetra Pak. Together they demonstrate the evolution from a largely formal distinction between loyalty and quantity rebates toward a more contextual assessment of market power, scheme structure, coverage, duration, foreclosure capability, economic effects and legitimate efficiencies.
