The capital flight accelerated as skepticism grows over whether massive spending on artificial intelligence infrastructure will yield tangible profitability. After a series of record highs earlier this year, the benchmark Kospi index recently slipped into bear-market territory, mirroring a broader global tech retreat.

Despite the equity exit, South Korean bonds remain an outlier; overseas buyers scooped up a net $1.65 billion in debt last month, bolstered by the country’s anticipated inclusion in the World Government Bond Index.
