Competition law in South Africa serves as the foundation for a fair and dynamic economy. Enacted through the Competition Act 89 of 1998, it ensures that markets remain competitive, preventing anti-competitive conduct that could harm businesses and consumers alike. This framework protects consumers, promotes small business growth, and fosters an inclusive economy.
Objectives of the Competition Act
The Competition Act was implemented to enhance economic efficiency and increase consumer choice. It supports small and medium-sized enterprises by ensuring fair access to the market, prevents the exploitation of dominant market positions, and encourages equitable participation by historically disadvantaged individuals.
Regulatory Bodies Enforcing Competition Law
The Competition Commission
The Competition Commission is responsible for investigating and addressing restrictive business practices, merger control, and anti-competitive conduct. It plays a crucial role in ensuring that businesses operate within the boundaries of competition law and do not engage in market manipulation.
The Competition Tribunal
The Competition Tribunal adjudicates cases referred by the Competition Commission. It reviews merger transactions, decides on complaints related to anti-competitive practices, and has the power to impose penalties on firms found guilty of breaching competition law.
The Competition Appeal Court
The Competition Appeal Court hears appeals against, and reviews of, Tribunal decisions and ensures that competition law is applied fairly and consistently. Under section 62(3) of the Act its decision is final on matters within the exclusive jurisdiction it shares with the Tribunal, namely the interpretation and application of the Act’s provisions on prohibited practices, mergers and the competition authorities. It is not the final word on everything, however. On questions of whether the Commission or Tribunal acted within its jurisdiction, and on constitutional matters arising under the Act, section 62(4) provides that an appeal lies to the Constitutional Court, with that court’s leave.
Prohibited Practices Under Competition Law
Price Fixing and Collusion
One of the most severe offences under competition law is price fixing. Businesses that collude to set prices at artificial levels eliminate competition, leading to higher costs for consumers and stifling market innovation. Section 4(1)(b) of the Act prohibits outright three practices between competitors: directly or indirectly fixing a purchase or selling price or any other trading condition, dividing markets, and collusive tendering. Unlike most other conduct, these cannot be justified by showing pro-competitive gains.
Market Division Agreements
When companies agree to divide territories, customers, or product markets among themselves, competition is significantly reduced. This practice prevents new entrants from competing and often leads to inflated prices and reduced consumer choice.
Bid Rigging
Bid rigging involves coordinated efforts by competitors to manipulate tender outcomes. This practice distorts fair competition, resulting in inflated contract prices and a lack of genuine competition in procurement processes.
Abuse of Dominance
A dominant company abusing its market position to eliminate competitors or exploit consumers is a key concern under competition law. Section 8 of the Act prohibits a dominant firm from, among other things, charging an excessive price to the detriment of consumers, refusing a competitor access to an essential facility when it is economically feasible to give it, refusing to supply scarce goods or services when that is economically feasible, and selling at predatory prices.
Merger Control and Regulation
Merger Classification
Mergers in South Africa are classified based on their size and potential economic impact. They fall into three categories: small, intermediate, and large mergers, measured against thresholds set by the Minister under section 11 of the Act. The classification determines the level of scrutiny and who approves the merger:
- Small mergers do not need to be notified, but under section 13(3) the Commission may require the parties to notify a small merger within six months after it is implemented.
- Intermediate mergers must be notified to the Competition Commission, which decides whether to approve them, approve them with conditions or prohibit them (section 14).
- Large mergers must also be notified to the Commission, but the Commission refers them to the Competition Tribunal with a recommendation, and the Tribunal decides (section 14A).
Neither an intermediate nor a large merger may be implemented until it has been approved.
Merger Assessments
Merger applications are assessed to determine their impact on competition and the broader public interest. The Competition Commission evaluates whether a proposed merger would result in market dominance, reduce competition, or harm employment opportunities.
Public Interest Considerations
Unlike many global competition law frameworks, South Africa places a strong emphasis on public interest factors when assessing mergers. Section 12A(3) requires the Commission or Tribunal to consider the merger’s effect on a particular industrial sector or region, employment, the ability of small and medium businesses and firms owned or controlled by historically disadvantaged persons to participate in the market, the ability of national industries to compete internationally, and a greater spread of ownership, in particular by historically disadvantaged persons and workers.
The Impact of Competition Law on Businesses
Encouraging Fair Competition
By enforcing competition law, businesses are required to operate transparently and competitively. This results in lower prices, improved product quality, and greater innovation, benefiting both companies and consumers.
Compliance Requirements
Companies must ensure compliance with competition law to avoid penalties and reputational damage. Engaging in anti-competitive conduct can result in hefty fines, legal consequences, and restrictions on future market activities. Specialist competition law advice is worth taking before entering into any arrangement with a competitor.
Penalties for Non-Compliance
Businesses found guilty of violating competition law can face severe penalties, including significant financial fines and restrictions on mergers and acquisitions. Under section 59 of the Act, the Competition Tribunal may impose an administrative penalty of up to 10% of the firm’s annual turnover in South Africa and its exports from South Africa in the preceding financial year, rising to 25% where the conduct is substantially a repeat of a prohibited practice previously found against the same firm. Individuals are exposed too. Since 1 May 2016, section 73A has made it a criminal offence for a director, or a person with management authority, to cause a firm to engage in price fixing, market division or collusive tendering, or knowingly to acquiesce in it. Under section 74 the penalty is a fine of up to R500 000, imprisonment of up to 10 years, or both. These measures act as a deterrent against engaging in restrictive business practices.
How the Competition Act Affects Consumers
Lower Prices and Greater Choice
One of the most direct benefits of competition law for consumers is the reduction in prices. By preventing monopolistic practices and promoting fair competition, businesses are incentivised to offer competitive prices, ultimately benefiting consumers with better deals and more choices.
Improved Product Quality and Innovation
With businesses competing for consumer attention, companies are driven to improve product quality and invest in innovation. The Competition Act ensures that dominant firms cannot suppress competition, leading to continuous improvements in goods and services across various industries.
Protection Against Exploitation
The Competition Act protects consumers from exploitative conduct by dominant firms, most directly through the prohibition on charging an excessive price to the detriment of consumers. False advertising and unfair contract terms are dealt with by a different statute, the Consumer Protection Act 68 of 2008, which prohibits false, misleading or deceptive representations (section 41) and unfair, unreasonable or unjust contract terms (section 48). Together, the two Acts ensure that businesses do not take advantage of their market position to overcharge or deceive customers.
Increased Market Access for Small Businesses
By promoting fair competition, the Act enables small and emerging businesses to enter markets without being unfairly pushed out by dominant players. This results in a broader range of products and services, enhancing consumer choice and market diversity.
Recent Developments in Competition Law
Strengthening of Regulatory Powers
In recent years, South Africa’s competition authorities have enhanced their enforcement mechanisms to address market abuse and anti-competitive practices. Stricter penalties and proactive investigations have strengthened compliance across industries.
The Role of Digital Markets
With the rise of digital commerce, competition law has adapted to regulate online markets effectively. Authorities are focusing on preventing dominant digital platforms from engaging in exclusionary practices that could hinder market entry for smaller competitors.
New Merger Thresholds from 1 May 2026
On 27 January 2026, the Minister of Trade, Industry and Competition published draft amendments to the merger thresholds for public comment (General Notice 7029, Government Gazette 54020). The new thresholds have since been finalised and took effect on 1 May 2026, replacing those in force since 2017. The Competition Commission now applies the following:
- Intermediate merger: combined annual turnover or assets of R1 billion or more (previously R600 million), and a target firm with annual turnover or assets of at least R200 million (previously R100 million).
- Large merger: combined annual turnover or assets of R9.5 billion or more (previously R6.6 billion), and a target firm with annual turnover or assets of at least R280 million (previously R190 million).
The final intermediate target threshold of R200 million is higher than the R175 million proposed in the January draft. Filing fees also increased, to R220 000 for an intermediate merger and R735 000 for a large merger. A transaction below the intermediate thresholds is a small merger.
Block Exemptions for Key Sectors
The Ports, Rail and Key Feeder Road Corridors block exemption was published on 8 May 2025 (General Notice 6182, Government Gazette 52624), allowing logistics sector players to collaborate in ways ordinarily prohibited under sections 4 and 5 of the Act. An amendment to the scope of the Energy Users Block Exemption was published on 5 January 2026 (Government Gazette 53921), broadening its scope.
The Importance of the Competition Act
Promoting a Fair Market Economy
The Competition Act plays a critical role in ensuring that businesses operate within a fair and balanced market. By preventing anti-competitive practices, it fosters a healthy economic environment where businesses of all sizes have the opportunity to compete and succeed.
Encouraging Economic Growth and Innovation
A competitive market encourages businesses to innovate and improve their products and services. The Act ensures that no single entity can monopolise an industry, which stimulates growth and provides consumers with access to better quality goods and services.
Supporting Small and Medium Enterprises
Small and medium enterprises (SMEs) often struggle to compete against large corporations. The Competition Act creates an environment where SMEs can thrive by preventing larger entities from engaging in exclusionary practices that could drive smaller businesses out of the market.
Strengthening South Africa’s Economic Landscape
A well-regulated competitive environment contributes to a stronger national economy. By promoting business integrity, investment opportunities, and economic inclusion, the Act ensures sustainable economic growth that benefits both businesses and consumers alike.
Conclusion
Competition law in South Africa is a vital component of the country’s economic framework. Through its regulatory bodies, enforcement mechanisms, and evolving legislation, it safeguards competitive markets, supports consumer welfare, and fosters economic transformation. Businesses looking to understand their broader legal obligations should also consider the fundamentals of commercial law in South Africa and the legal requirements for starting a business, both of which intersect closely with competition law compliance.
Updated/Reviewed 24 March 2026 — Added proposed 2026 merger threshold amendments and 2025 block exemptions (Ports, Rail, Energy). Confirmed core provisions of the Competition Act remain unchanged. Added internal links.
Updated 29 September 2026 – The new merger thresholds are now in force from 1 May 2026, not proposed: intermediate mergers at R1 billion combined and R200 million for the target firm (higher than the R175 million in the January 2026 draft), large mergers at R9.5 billion and R280 million, with filing fees of R220 000 and R735 000. Corrected three further points: the Competition Appeal Court is final only on matters within its exclusive jurisdiction, with constitutional and jurisdictional questions appealable to the Constitutional Court; large mergers are decided by the Competition Tribunal rather than the Commission; and false advertising and unfair contract terms fall under the Consumer Protection Act, not the Competition Act. Added the section 59 administrative penalty caps of 10% and 25% of turnover, the section 73A criminal offence for directors and managers involved in cartel conduct, and the gazette dates of the ports and energy block exemptions (the energy amendment was published on 5 January 2026, not in 2025).
