    Penalties imposed on major corporate groups so far in 2026 have exceeded the combined amount levied over the previous several years, according to a report by Korea Economic Daily Global. The increase comes as the Korea Fair Trade Commission, the country’s competition watchdog, revives a specialized investigative unit known for pursuing difficult cases involving large conglomerates.

    The development marks a shift toward more aggressive enforcement at the KFTC as authorities focus on alleged abuses of market power, collusion and transactions involving affiliates of South Korea’s sprawling family-controlled business groups, commonly known as chaebol, according to Korea Economic Daily Global.

    The tougher approach carries potentially significant consequences for some of the country’s largest companies. Chaebol dominate industries ranging from semiconductors and automobiles to retail and chemicals, making changes in competition policy an important consideration for investors and corporate executives.

    The surge in penalties has been driven in part by major cartel cases. In February, the KFTC decided to impose a combined 408.3 billion won ($294 million at recent exchange rates) in fines on CJ CheilJedang, Samyang Corp. and TS Corp. over alleged coordination of sugar prices. The regulator described the case as one of its largest cartel enforcement actions, with the total penalty ranking second among such cases in its history.

    The broader rise in enforcement also reflects the return of an investigative operation that had earned a reputation as a “grim reaper” of corporate groups because of its focus on potentially abusive practices by powerful conglomerates, Korea Economic Daily Global reported.

    Its revival adds to signs that the commission is placing greater emphasis on investigations involving large companies and their affiliates. Such cases can involve allegations including unfair internal transactions, improper support for related companies and conduct that regulators believe restricts competition.

    South Korea has long sought to balance the economic importance of its biggest corporate groups with efforts to curb practices that can disadvantage smaller rivals. The chaebol helped drive the country’s rapid industrialization and remain central to its export economy, but their market influence has also made them recurring targets of antitrust and corporate-governance reforms.

    Previous enforcement actions show the potential scale of that regulatory exposure. The KFTC has imposed large penalties in cases involving industries ranging from technology and construction to food and transportation, while courts have at times been called on to determine whether the regulator’s sanctions should stand.
