Record Petrochemical Cartel Revives Calls for Tougher Penalties in Korea
The indictment of six petrochemical companies and 37 people over an alleged 16.4 trillion won cartel has intensified debate over whether Korea's current maximum prison term and asset-recovery rules provide enough deterrence.
South Korea is facing renewed calls to strengthen criminal penalties for cartel conduct after prosecutors indicted six petrochemical companies and 37 current and former executives and employees in what they described as their largest cartel case to date.
The companies named in the October 1 indictment are LG Chem, Aekyung Chemical, OCI, Lotte Fine Chemical, PKC and UNID. Prosecutors estimated the alleged collusion at 16.3961 trillion won and charged the defendants with violating the Fair Trade Act.
The scale of the case has placed fresh attention on the gap between the economic value attributed to major cartels and the sanctions available under existing law. Businesses found to have engaged in unfair collaborative practices, including agreements on prices or production volumes, can face imprisonment of up to three years or a fine of up to 200 million won. Courts may impose both penalties.
Investigators have argued that the current framework does not adequately address either punishment or the recovery of illicit gains. They cited the difficulty of calculating the precise profit generated by collusion and suggested that legislation could allow a specified share of sales to be treated as criminal proceeds. They also called for higher statutory penalties.
The debate extends beyond the petrochemical sector. President Lee Jae Myung ordered institutional changes in February after large price-fixing cases emerged in the flour, sugar and electricity industries. Those instructions included reviewing maximum penalties and developing stronger mechanisms to reclaim illegal gains.
A sugar price-fixing case has become a prominent example in the discussion. In April, former executives of CJ CheilJedang and Samyang were each sentenced to two years and six months in prison, suspended for three years, and fined 100 million won in the first trial of a case valued at 3.2715 trillion won. Prosecutors appealed, arguing that the sentences were too lenient given the seriousness and scale of the conduct. The appeal remains pending.
Enforcement capacity is also changing. Responsibility for major cartel investigations moved from the Seoul Central District Prosecutors' Office to the newly launched Serious Crimes Investigation Agency. Its Antitrust Investigation Bureau was designed with four divisions and a staffing complement of 122, compared with roughly 17 prosecutors and investigators in the previous unit. Seventy-eight investigators at Grade 5 or below were reportedly assigned when the agency began operations on October 2.
The combination of a record-scale prosecution and a much larger investigative organization is likely to keep pressure on lawmakers to align penalties, proceeds recovery and enforcement resources. The central policy question is whether Korea can make cartel sanctions strong enough to deter executives while ensuring that punishment remains proportionate and supported by evidence.
