By introducing special legislation for two core industries—steel and petrochemicals—the Korean government has put industrial restructuring on a deadline. The Special Act on Strengthening the Competitiveness of the Steel Industry and Transitioning to Carbon Neutrality, known as the K-Steel Act (Act No. 21202), was enacted on December 16, 2025, followed on December 30 by the Special Act on Strengthening the Competitiveness of and Supporting the Petrochemical Industry (Act No. 21251). The backdrop is a triple burden: structurally low growth caused by slowing global demand and increased Chinese supply, a cost disadvantage stemming from an energy-intensive, naphtha-based structure, and exposure to carbon regulation.

The K-Steel Act — a state-led low-carbon transition under a temporary law effective through 2028. The Act establishes a top-down implementation framework under the Prime Minister, mandates five-year master plans and annual implementation plans, and provides for the designation of low-carbon steel special zones and even direct installation by central and local governments of infrastructure such as power grids and hydrogen supply networks, allowing the state to share corporate infrastructure investment risk. Crucially, its core special provisions expire on December 31, 2028. This temporary structure creates policy leverage by placing companies under time pressure to decide on closing aging blast furnaces and investing in upgraded electric arc furnaces and hydrogen-reduced ironmaking.

The Petrochemical Special Act — easing M&A and concerted-action regulation is central. Effective April 21, 2026, the Act broadens the industry's legal scope beyond naphtha to include natural gas, biomass, and recycled feedstocks and formally designates high-performance chemical materials for semiconductors and batteries and greenhouse-gas reduction technologies as “core strategic technologies.” Regulatory relief is central to restructuring. It reduces the total merger review period for approved business restructuring plans from 120 days—an initial review within 30 days plus an extension of up to 90 days—to 90 days, comprising 30 days plus an extension of up to 60 days, shortening the approval wait for megadeals. With approval from the Minister of Trade, Industry and Energy, it also legalizes concerted actions including adjustments to operating rates, capacity reductions, consolidation of product-specific facilities, and voluntary plant closures. Companies may even exchange non-public management information, such as facility utilization rates, unit costs, and product-level profit and loss, enabling practical restructuring simulations. The report nevertheless notes that companies must proactively manage risks including delays in energy infrastructure supply, green premiums for low-carbon products, and national certification.

Implications for M&A. First, shorter merger reviews and exemptions for concerted action have opened an institutional window for major steel and petrochemical M&A and facility consolidation. Given the temporary law's deadline, transactions are likely to cluster through 2028. Second, restructuring transactions such as carve-outs, joint ventures, and asset swaps are expected to expand as naphtha cracking centers are integrated and plants closed. Third, investment in the transition to hydrogen-reduced ironmaking, recycled feedstocks, and specialty materials may catalyze bolt-on acquisitions of and strategic equity investments in related technology companies.
