Understanding Abuse of Dominance

What is an abuse of dominance and why is it bad?

Being a dominant player in a market is by itself not anti-competitive, nor does the Competition Act prevent businesses from striving to achieve it based on their own merits. A dominant position achieved or maintained through conduct arising from efficiencies, such as through successful innovation or economies of scale, will not be regarded as an abuse of dominance. However, when a dominant business in the market seeks to protect, enhance or perpetuate its dominant position in ways unrelated to competitive merit, it unduly restricts competition, and hurts consumers and businesses. Such conduct may constitute an abuse of dominance, and infringe Section 47 of the Competition Act.

Recognising abuse of dominance?

A two-step test is used to assess whether there is abuse of dominance:

Test 1: Whether the business is dominant. A market leader is likely to be dominant when one or more of these factors are satisfied:

  • It has a market share of 60% and above

  • There are few or no competitors that its customers can go to

  • Its customers do not have significant bargaining power

  • Newcomers find it difficult to enter the market for instance, because of high capital cost or technological barriers

Test 2: If it is dominant, whether it is abusing that dominant position in a market. Being dominant is not against the law. But some dominant businesses may either block rivals from competing against it or stop rivals from entering the market. Abusive tactics may include:

  • Exclusive dealing: When the dominant business binds other businesses into working exclusively with itself

  • Predatory pricing: When it sets below-cost prices to drive competitors out of the market

  • Discount schemes: When discounts are conditional on buyers purchasing only or primarily from the dominant business and not from other competitors

  • Tying and bundling: When it makes the purchase of one product conditional on the purchase of other products and services from the dominant business

  • Refusal to supply: When it withholds key products or services essential to other businesses.
