Monopoly Regulation and Fair Trade Act (MRFTA) of South Korea

Introduction

The Monopoly Regulation and Fair Trade Act (MRFTA, 독점규제 및 공정거래에 관한 법률) , enacted in 1980 and comprehensively revised over four decades, is South Korea’s primary competition and antitrust statute. The Act prohibits abuse of market dominance, anticompetitive mergers, economic concentration (chaebol regulation), and unfair trade practices. The Korea Fair Trade Commission (KFTC) (공정거래위원회) enforces the Act with quasi-judicial and quasi-legislative powers.

Historical Development

Economic Background

The MRFTA was enacted in 1980 during a period of heavy state-led economic development dominated by large business groups (chaebol). Unlike Western competition laws that emerged from market economies, the MRFTA was designed to introduce competition principles into a government-directed economy.

Major Revisions

• 1986: Expanded unfair trade practice regulation
• 1990: Chaebol regulation provisions strengthened
• 1996: Merger regulation enhanced
• 1999: Post-Asian Financial Crisis reforms — stricter chaebol regulation
• 2005: Private damages actions introduced
• 2013: Enhanced enforcement powers for KFTC
• 2021: Amendments to address platform economy competition issues

Key Provisions

Abuse of Market Dominance (Article 3-2)

An “abuser” is an enterprise with market dominance, defined as:

• Single enterprise with 50%+ market share
• Top three enterprises with 75%+ combined market share (excluding enterprises with less than 10%)

Prohibited conduct includes:

• Unreasonable price fixing, output restriction, or distribution control
• Unreasonable interference with other enterprises’ business activities
• Unreasonable exclusion of competitors
• Unfair dealing with counterparties

Merger Regulation (Articles 7–12)

Merger review is required where:

• The combined assets or revenue of the acquiring and target companies exceed KRW 300 billion (approximately USD 225 million)
• Either party has assets or revenue exceeding KRW 200 billion

The KFTC evaluates whether the merger substantially lessens competition in a relevant market. The assessment considers:

• Market concentration (HHI and market share)
• Entry barriers
• Competitive effects (coordinated and unilateral)
• Efficiencies

Unfair Trade Practices (Article 23)

Twelve categories of unfair trade practices are prohibited:

• Refusal or restriction of dealing
• Price discrimination
• Unfair inducement of customers
• Tying arrangements
• Abuse of superior bargaining position
• Interference with business activities

Chaebol Regulation (Articles 8–14-2)

Distinctive provisions regulating large business groups:

• Cross-shareholding limits: Prohibition on circular investment within business groups
• Debt guarantee prohibition: Between group companies
• Voting right restrictions: For financial or insurance companies within groups
• Large-scale internal transaction disclosure: Internal transactions exceeding specified thresholds
• Designation: The KFTC annually designates business groups subject to regulation (assets over KRW 5 trillion)

Korea Fair Trade Commission (KFTC)

Structure

The KFTC is an autonomous central administrative agency under the Prime Minister’s Office, comprising nine commissioners (including one chairperson and three vice-chairs). Commissioners have tenure protection (fixed terms).

Enforcement Powers

• Corrective orders: Cease-and-desist orders, structural remedies
• Surcharges: Administrative fines (up to 10% of relevant revenue for abuse and cartels; up to 5% for unfair trade practices)
• Criminal referrals: To the prosecution service for serious violations
• Consent orders: Introduced in 2014 for voluntary compliance

Private Enforcement

The MRFTA provides for:

• Damages claims (Article 56): Actual damages (no punitive damages)
• Reliance on KFTC findings: KFTC factual findings are binding on civil courts
• Limitation period: Three years from discovery of violation

Conclusion

The MRFTA has evolved from an industrial policy instrument into a mature competition law framework. Its distinctive chaebol regulation provisions address economic concentration concerns unique to Korea. The KFTC’s active enforcement — including landmark cases against global technology companies and domestic conglomerates — has established Korea as a significant competition law jurisdiction.
