South Korea Overtakes UK Stock Market
Analysis based on 7 articles · First reported Apr 28, 2026 · Last updated Apr 28, 2026
The global financial markets are experiencing a structural rebalancing, with Asian chip powerhouses like South Korea and Taiwan gaining significant market capitalization due to their dominance in the AI hardware supply chain. This shift is drawing sustained structural capital inflows to these economies, while traditional markets like the United Kingdom, dominated by older sectors, are lagging.
South Korea has surpassed the United Kingdom to become the world's eighth-biggest stock market, with its market capitalization surging over 45% to $4.04 trillion in 2026. This growth is primarily fueled by a rally in artificial intelligence-linked technology companies such as Samsung Electronics and SK Hynix, which now account for more than 40% of the KOSPI index's total market cap. President Lee Jae Myung's pro-market policies and corporate governance reforms have also contributed to this ascent. Taiwan's stock market has similarly overtaken the United Kingdom's, becoming the seventh-largest globally, driven by TSMC. In contrast, the United Kingdom's FTSE 100 Index has seen modest gains, reflecting its reliance on traditional sectors and slower innovation compared to the AI boom. Wall Street strategists, including Goldman Sachs, remain bullish on South Korean stocks, citing favorable valuations and earnings upgrades from AI demand.
