The Competition Act 2010, enforced by the Malaysia Competition Commission (MyCC), prohibits two things: anti-competitive agreements such as price-fixing, bid-rigging and market-sharing (the Chapter 1 prohibition), and abuse of a dominant market position (the Chapter 2 prohibition). A proven breach can cost an enterprise a financial penalty of up to 10% of its worldwide turnover over the period of the infringement. The Act applies to nearly all commercial activity. A Competition (Amendment) Bill 2026 — passed by both the Dewan Rakyat (6 July 2026) and the Dewan Negara (27 July 2026), but not yet confirmed as having received royal assent or been gazetted into force — would further strengthen MyCC's enforcement and settlement powers.
- Cartel conduct — price-fixing, market-sharing, bid-rigging and limiting production — is deemed anti-competitive under Section 4(2), so no separate proof of harm is needed.
- Abusing a dominant position (Section 10) is banned; MyCC generally treats a market share above 60% as an indicator of dominance.
- The maximum financial penalty is up to 10% of an enterprise's worldwide turnover over the infringement period.
- A leniency regime (Section 41) offers up to a 100% penalty reduction for cartel members who come forward and cooperate.
Who this applies to: Business owners, directors, compliance officers and legal advisers operating in Malaysia.

Agreeing with a rival to keep prices high, or quietly taking turns to win government tenders, is not shrewd business in Malaysia — it is a breach of the law that can cost a company one-tenth of everything it earns worldwide.
That law is the Competition Act 2010, which came into force on 1 January 2012 and is enforced by the Malaysia Competition Commission (MyCC). It applies broadly across the economy, and it turns on two prohibitions.
What agreements between businesses are banned?
The first prohibition (Chapter 1) targets anti-competitive agreements. Section 4 catches both horizontal deals (between competitors) and vertical ones (along a supply chain) that significantly prevent, restrict or distort competition.
Certain conduct is treated so seriously that Section 4(2) deems it anti-competitive by its object — meaning MyCC does not have to prove market harm separately. That list includes agreements to:
- fix prices or trading conditions;
- share markets or sources of supply;
- limit or control production, market outlets, technical development or investment; and
- rig bids or tenders.
Bid-rigging — cover bidding, bid suppression or “taking turns” to win contracts — falls squarely in this category and is a frequent target of enforcement.
What counts as abusing a dominant position?
The second prohibition (Chapter 2, Section 10) bans an enterprise from abusing a dominant position in a market. Being big is not itself illegal; abusing that power is.
MyCC generally regards a market share above 60% as an indicator of dominance, though it also weighs barriers to entry and buyer power. Abusive conduct can include predatory pricing, price discrimination, refusing to supply, and imposing unfair prices or trading conditions.
What are the penalties — and any way out?
A proven infringement of either prohibition can attract a financial penalty of up to 10% of the enterprise’s worldwide turnover over the period the infringement lasted. For a group, that turnover can be assessed across the parent and subsidiaries as a single economic unit.
There are relief valves. A leniency programme (Section 41) offers up to a 100% reduction in penalty for a cartel participant who discloses its involvement and cooperates — a strong incentive to be the first to confess.
What changes under the Competition (Amendment) Bill 2026?
Parliament moved to sharpen MyCC’s powers in 2026. The Competition (Amendment) Bill 2026 passed the House of Representatives (Dewan Rakyat) on 6 July 2026 and was passed by the Senate (Dewan Negara) on 27 July 2026. As of this draft, cited sources do not confirm that the Bill has received royal assent or been gazetted into force, so its provisions are not yet law. Key changes reported by legal commentators and news reports include:
- a formal settlement mechanism, giving enterprises that admit liability early up to a 40% penalty reduction — separate from, and in addition to, any leniency discount;
- broader interim powers, including warning letters after preliminary inquiries and interim directions during live investigations; and
- late-payment charges for penalties not paid on time.
Notably, the Bill did not introduce a general merger-control regime. Malaysia still has no economy-wide requirement to notify or seek clearance for mergers, acquisitions or joint ventures under the Act.
What’s next
If you run a business in Malaysia, treat pricing talks, tender coordination and information-sharing with competitors as high-risk zones, and keep a written competition-compliance policy. For the authoritative text and the latest guidelines, consult MyCC directly, and take formal legal advice before relying on any exemption or the leniency programme.
Does the Competition Act 2010 require merger approval in Malaysia?
No. The Act contains no general requirement to notify or seek clearance for a merger, acquisition or joint venture, and the Competition (Amendment) Bill 2026 did not introduce an economy-wide merger-control regime.
Who enforces the Competition Act 2010?
The Malaysia Competition Commission (MyCC), an independent statutory body, investigates suspected breaches and can impose financial penalties and directions.
The following are deliberately unstated or described only qualitatively until confirmed by a subject-matter expert:
- Whether the Competition (Amendment) Bill 2026 has since received royal assent and been gazetted, and its commencement date (as of the correction date, only passage by both Houses of Parliament is confirmed by cited sources; no royal assent or gazettement is confirmed).
- The interim-directions / warning-letter powers and the late-payment charges are supported only by the ZICO Law commentary; confirm against the gazetted amendment text once available.
- The >60% market-share dominance indicator and the Section 4(2)/Section 10/Section 41 numbering against the current consolidated MyCC guidelines and Act text.
- Whether the settlement-reduction provision sits at Section 38A in the enacted amendment (news commentary cites Section 38A).
