As of September 18, 2025 (UTC), South Korea’s KOSPI Index closed at 3,449.37, once again reaching a record high. Year-to-date, the index has surged over 38%, ranking among the top performers of major global stock indices. This performance highlights South Korea’s robust growth in key sectors such as semiconductors, consumer electronics, and electric vehicles, while also benefiting from the broader global trend of capital flows into Asian markets.
This rapid climb in the index is not solely the result of capital inflows; it also reflects a strong market response to positive policy expectations. In the near term, volatility in the KOSPI remains pronounced, and investors should be mindful of both market sentiment and the influence of international capital flows.
President Lee Jae-myung has announced a delay in the capital gains tax reform originally set for 2025, especially regarding the redefinition of the “major shareholder” threshold. This move has alleviated investor concerns about increased tax liabilities, restored confidence, and resulted in a marked boost in market liquidity.
Additionally, the South Korean government is advancing corporate governance reforms, encouraging companies to improve shareholder returns and increase transparency. These policies are providing positive near-term support for stock prices and are drawing long-term investors to the market’s growth potential.
Historically, the South Korean stock market has been affected by the so-called “Korea Discount,” with domestic company valuations consistently lower than those of global competitors. This is chiefly attributable to concerns over corporate governance, shareholder returns, and market transparency. As government reforms take hold and companies bolster profits and optimize dividend policies, this discount is expected to gradually diminish.
For global investors, the “Korea Discount” translates into potential value-driven opportunities within the Korean equities market. Nevertheless, careful attention to policy shifts and market volatility remains essential to manage associated risks.
The KOSPI’s historic high in 2025 highlights the resilience of South Korea’s economy and the tangible impact of government policy. While near-term volatility remains, continued reforms and industry advancement should drive sustained growth in the equities market. Investors are encouraged to closely follow policy trends, industry dynamics, and global capital flows to identify and act on structural investment opportunities.
