South Korea’s KOSPI index fell 12% year-to-date through September 2024, with foreign investors pulling a net $8.0 billion from Korean equities in Q3 alone. Samsung Electronics shares dropped 10% over the same period, dragging down the broader tech-heavy market as concerns over weakening memory demand and Chinese competition grew. Meanwhile, Taiwan’s TAIEX rose 18% YTD, buoyed by a $5.0 billion net inflow of foreign capital in Q3. TSMC reported Q2 2024 revenue of $23.0 billion, up 35% year-on-year, pushing Taiwan’s total market capitalization to roughly $2.0 trillion from $1.7 trillion a year earlier.

The reallocation reflects a decisive Middle East shift toward pure-play AI infrastructure, where Taiwanese fabs are seen as the indispensable engine of the next compute wave. Gulf sovereign wealth funds, which have been diversifying away from oil-linked assets, now view Taiwan as a safer beta to AI growth than Korea’s mixed memory‑logic portfolio. For South Korea, the outflow threatens its ambition to become a global AI hub, potentially slowing domestic chip R&D and forcing policymakers to consider fresh incentives or currency interventions to stem capital flight. Second‑order effects include a possible valuation stretch in Taiwan’s semiconductor stocks, which could attract speculative inflows and raise bubble concerns, while Korea may accelerate efforts to attract Middle East fab partnerships to regain lost ground.
