South Korea’s equity market has surged, driven by AI chip giants Samsung Electronics and SK Hynix, tripling the Kospi since early 2025. The index now sits at $4.4tn, making it the world’s eighth largest and outpacing Germany and France. Seoul pushed reforms to attract foreign capital and win an MSCI developed‑market upgrade for more than a decade.

MSCI kept South Korea on the emerging‑market list, citing lack of a fully convertible offshore won and weak short‑selling settlement. The regulator highlighted that 24‑hour onshore trading does not equal the liquidity of a true market. Analysts note the upgrade could attract roughly $30bn from passive funds, but the absence of offshore trading keeps concerns alive.

Investors face a dilemma: the market’s valuation grows while access remains constrained. A developed‑market status would lift the “Korea discount,” yet only 3% of MSCI’s developed index would be Korean, limiting the upside. Any further liberalisation could trigger capital outflows from small and mid‑caps, concentrating wealth in chip leaders. Firms – an investor should weigh the potential inflow against the risk of currency volatility.
