South Korea’s petchem overhaul stalls amid rivalries, government prepares decisive intervention

Two years into the crisis, South Korea’s restructuring drive remains slow and fragmented. The progress seems to be hampered by deep corporate rivalries, structural inefficiencies, and inconsistent policy direction. While the government is expected to announce as early as December a restructuring plan for the Daesan petrochemical industrial complex, industry observers are wondering whether this hands-on intervention will differ from earlier efforts and pave the way for a faster transformation.

Crisis drags on since 2023 despite repeated rescue efforts

Alarm bells first rang for South Korea’s petrochemical industry in late 2023, when oversupply and collapsing margins began forcing plant closures, asset sales, and mergers. By mid-2024, the government stepped in with tax incentives, financial aid, and a task force to steer the sector through mounting competition from low-cost Chinese products.

In August 2025, officials announced that ten major producers had agreed to cut naphtha-cracking capacity by 2.7–3.7 million tons/year — up to 25% of national output — under an industry-wide restructuring plan. A month later, creditor banks launched a unified support framework to aid financially sound firms committed to capacity cuts. Only companies presenting concrete plans for facility consolidation and supply reductions will qualify for assistance, which may include debt rollovers, interest-rate relief, and regulatory incentives.

Producers locked in stalemate over capacity cuts

Since the announcement in August about obligatory production cutbacks at naphtha cracking centers (NCC) as a concrete step, the pressure has been mounting but consensus remains elusive. Major naphtha cracker operators such as SK Geocentric, Korea Petrochemical Ind., and S-Oil have yet to agree on who should bear the brunt of production cuts. Each firm insists on its own competitiveness, while S-Oil’s massive Shaheen Project, set to add 1.8 million tons of new ethylene output next year, threatens to deepen the supply glut.

Industry insiders say S-Oil can consume only about 1.3 million tons of this output internally and must sell the remainder — a task complicated by limited logistics and weak downstream demand. Other players argue the project should not be exempt from cutbacks, raising accusations of “free-riding” and stalling collective action.

Government steps in with pilot restructuring at Daesan

With voluntary efforts failing, the government is preparing to take a stronger hand. A comprehensive restructuring plan for the Daesan petrochemical complex is expected by the end of the year. The initiative will serve as a pilot project for nationwide reform and may include mergers such as the proposed LOTTE Chemical–HD Hyundai Chemical integration.

Authorities plan to offer financial, tax, and R&D support under the Corporate Vitality Act, while also seeking adjustments to the Fair Trade Act to ease restrictions on corporate combinations. The move reflects a growing sense within the Ministry of Trade, Industry and Energy (MOTIE) that voluntary self-help alone will not restore balance to the sector.

Meanwhile, LG Chem Ltd. is reportedly planning to end operations at its HDPE plant in Daesan. The timeline for the closure has not been confirmed, and the company has not officially verified the information. Whether this plant will be included in the government’s restructuring plan is yet to be seen.

Underlying structural weaknesses persist

Yet analysts warn that deeper structural challenges continue to undermine competitiveness. Industrial power prices have surged nearly 70% in three years, now exceeding residential rates by 15%, while overlapping environmental regulations and policy inconsistency have eroded investor confidence. The lack of a coherent long-term strategy — balancing energy reform, innovation, and sustainability — has left producers struggling to adapt.

Conclusion: Real reform still uncertain

As Seoul prepares a more hands-on intervention, the industry faces a defining moment. The Daesan plan could mark the start of a long-awaited transformation — or simply the next phase in a cycle of short-lived fixes. Without confronting high energy costs, regulatory rigidity, and the absence of unified direction, South Korea’s petrochemical restructuring risks becoming another exercise in delay rather than a true path to renewal.
