South Korean equities saw a significant rally on Wednesday following the government’s announcement of a ban on duplicate listings for parent and subsidiary companies. The benchmark Kospi jumped 5% as authorities moved to eliminate “double listings,” a practice often blamed for the “Korea discount”—the chronic undervaluation of local stocks compared to global peers.
Financial Services Commission (FSC) Chairman Lee Eog-weon stated that the government will implement strict screening to prohibit simultaneous listings in principle, ensuring the rights of general shareholders are protected from value dilution. This structural remedy is expected to reduce the historical reliance of large conglomerates, or chaebol, on subsidiary IPOs for fundraising.
The initiative is central to President Lee Jae Myung’s broader “K-Premium” overhaul. Speaking at a capital market reform meeting at Cheong Wa Dae on Wednesday, March 18, 2026, the President vowed to transform the market’s reputation by tackling corporate governance flaws, market distortions, and geopolitical risks. He emphasized that strengthening the capital market is a national priority that could also help alleviate the excessive concentration of wealth in real estate.
To support this transition, the government outlined four key policy pillars: restoring trust, strengthening shareholder protection, fostering innovation, and improving market accessibility. Beyond regulatory curbs, authorities plan to “name-and-shame” companies with low price-to-book ratios to encourage corporate value enhancement. Additionally, regulators expressed readiness to expand a 100 trillion won market stabilization plan if necessary to manage external volatility.
Market sentiment remains highly positive, further bolstered by an optimistic outlook on AI demand from Samsung Electronics, which saw its stock price climb over 7% alongside SK Hynix.
