A significant shift is taking place in the South Korean investment landscape as young people are increasingly turning away from local stocks and embracing markets in the United States and digital assets. Data reveals a dramatic decline in participation among investors aged 20-30 in domestic stock markets, raising concerns about market liquidity and stability. This trend marks a major departure from past practices, with many young South Koreans citing lack of profitability as a key reason for their shift towards US stocks and cryptocurrencies. Interviews reveal the appeal of US stocks and digital assets, offering more diverse investment opportunities and perceived higher potential returns. Despite this change, older investors continue to hold onto traditional markets, leaving a dynamic imbalance within the market structure.
