In a surprising turn of events, South Korea's presence in the global financial markets has grown significantly.
Recently, South Korea's weight in the MSCI Emerging Markets Index soared to about 21%, placing it just one percentage point behind powerhouse China. This is a remarkable shift, especially considering it happened in just eight months. The interesting part is that this occurred even as foreign investors were selling off Korean stocks, amounting to nearly ₩94 trillion this year. So, how can a country's index weight increase while foreigners are selling? It's a paradox that reveals a major change in the market's structure, driven by artificial intelligence.
The core reason is the explosive growth in AI-related semiconductor stocks. First, the global demand for AI technology, led by companies like Nvidia, has created a massive need for high-performance memory chips like HBM. This directly benefits Korean giants such as SK hynix. As their profits surged, their stock prices skyrocketed. Second, the MSCI index isn't just about the number of shares; it's calculated based on the US dollar value of stocks available to foreign investors, known as the free-float market capitalization. The surge in stock prices was so powerful that it increased the total value of the Korean market much faster than foreigners could sell their shares. In essence, the value of the shares they continued to hold became much larger, increasing their overall ownership percentage and Korea's index weight.
This isn't an isolated event. We're seeing a fundamental re-centering of the Emerging Markets index around the AI supply chain. Earlier this year, Taiwan, home to the world's largest chipmaker TSMC, overtook China as the top country in the index. Korea's rapid ascent is part of this larger trend, concentrating the index's weight in these two key semiconductor hubs. Adding to the momentum are Korea's own policy efforts, such as launching a 24-hour foreign exchange market to improve accessibility for global investors. This move is aimed at earning an upgrade to 'Developed Market' status from MSCI, which further boosts investor confidence.
In short, the story of Korea's rising influence is a story of the AI revolution. It's a clear example of how technological trends can reshape global capital flows, sometimes in counterintuitive ways.
