Retail investors in South Korea have reached the limits of stock investment borrowing capacity at local brokerages, according to the Korea Capital Market Institute. This situation arises as the country's stock market, particularly in AI-driven chipmaker stocks like Samsung Electronics and SK Hynix, experiences a significant rally.
Kim Sei-wan, President of the Korea Capital Market Institute, stated that brokerage firms have strict regulations on borrowing caps, which have now been met, making it difficult for retail investors to secure additional funds for investment. The KOSPI index has surged 83% this year, following a 76% rise last year, making it the world's top performer.
Retail investments in the KOSPI have reached 79 trillion won ($51.8 billion) year-to-date, playing a key role in the benchmark index's ascent. This contrasts with foreign investors who have sold 124 trillion won of shares for profit-taking. Last year, retail investors had sold 26 trillion won of KOSPI shares.
Data from the Korea Financial Investment Association indicates that borrowed investments by retail investors in the KOSPI market hit a record 29 trillion won as of Tuesday. This represents a substantial 71% increase from the 17 trillion won recorded at the end of 2025.
