South Korea Set to Dramatically Increase Antitrust Penalties: What Businesses Need to Know
South Korea’s Fair Trade Commission (KFTC) has announced sweeping changes to its penalty guidelines for antitrust violations, signaling a significantly tougher stance on anti-competitive behavior. The revisions, finalized on March 9, 2026, will substantially increase fines and introduce stricter penalties for repeat offenders, impacting businesses operating within the country.
A Major Shift in Enforcement
The KFTC’s overhaul of the “Detailed Standards for Imposing Surcharges” (the “Overcharge Notice”) stems from a December 30, 2025, plan to improve the penalty system. The core objective is to deter unlawful practices through more impactful financial repercussions. These changes represent a fundamental shift in how the KFTC approaches antitrust enforcement.
Key Changes to the Overcharge Notice
Lowering the Threshold for Penalties
The most significant change involves a substantial increase in the lower limits of the surcharge rate applied to calculate penalties. This rate, used in conjunction with relevant sales, determines the fine amount. The KFTC has dramatically increased the minimum surcharge rates for all types of violations. Specifically, the minimum rate for collusion has been increased twentyfold, while rates for unfair support and illicit profit-taking have increased fivefold and nearly twofold, respectively.
Increased Penalties for Repeat Offenders
The revised guidelines introduce significantly harsher penalties for companies with a history of antitrust violations. A single prior violation can lead to a surcharge increase of up to 50% and the surcharge can reach 100% depending on the number of violations. Critically, in cases of collusion, a surcharge of up to 100% can be applied if a company has been penalized for collusion within the past ten years – a substantial increase from the previous five-year timeframe and maximum 80% surcharge.
Reduced Discretion in Penalty Reductions
The KFTC is also reducing its discretionary power to lower penalties. The conditions for receiving a reduction in surcharges have been narrowed, and the maximum reduction for cooperating with investigations has been reduced from 20% to 10%. Self-correction reductions have also been reduced from 30% to 10%, and a previous 10% reduction for minor negligence has been eliminated. The KFTC will now have the authority to revoke previously granted reductions if a company changes its testimony during legal proceedings.
Scope of Application
The amended Overcharge Notice will undergo a 20-day public notice period, beginning March 10, 2026, before finalization and implementation by the KFTC. Implementation is anticipated in early April 2026. The new rules will apply to ongoing violations as of the effective date, but will not be applied retroactively to violations that concluded before the implementation date.
Implications for Businesses
These changes have far-reaching implications for businesses operating in South Korea. The potential for significantly higher penalties demands a proactive approach to antitrust compliance. Here’s what companies should consider:
- Increased Financial Risk: Businesses face substantially higher financial exposure in the event of an antitrust violation.
- Enhanced Compliance Programs: Robust antitrust compliance programs are now more critical than ever.
- Internal Audits: Regular internal audits to identify and address potential antitrust risks are essential.
- Proactive Legal Counsel: Seeking legal counsel to review business practices and ensure compliance is highly recommended.
Potential Future Developments
Further changes may be on the horizon. Amendments to the Fair Trade Act are currently being proposed that would significantly increase the upper limits of surcharge rates. A bill proposed on February 26, 2026, could lead to even larger penalties, potentially increasing the overall scale of fines imposed by the KFTC.
