KOSPI Breaks 4-Year Record, Surging to New All-Time High
11 Sep
Summary
- KOSPI reaches record high of 3,314.53 on September 10, 2025
- KOSDAQ also hits yearly high, closing at 833.0 points
- Foreign investors and institutions drive the market rally
On September 10, 2025, the KOSPI, South Korea's benchmark stock index, rewrote history by reaching a new all-time high of 3,314.53, surpassing the previous record set on July 6, 2021. This milestone comes just a day after Wall Street's major indexes also closed at record levels.
The KOSPI's rally was driven by strong buying from foreign investors, who purchased 1.311 trillion won worth of shares, as well as institutional investors who bought 90.29 billion won in stocks. Leading the charge was a 5.56% surge in the share price of SK Hynix, a major semiconductor company.
The KOSDAQ, South Korea's tech-heavy index, also hit a yearly high, closing at 833.0 points, up 0.99% from the previous day. Market analysts attribute the overall market surge to investors' optimism that the US Federal Reserve will cut interest rates next week, which is expected to increase liquidity, as well as the anticipation that the new Lee Jae Myung administration will relax capital gains tax rules for major shareholders.
Since September 2, the KOSPI has risen for seven consecutive trading days, gaining 38.1% so far in 2025 and 22.8% since the inauguration of the Lee administration in June. Despite the strong foreign buying, the won-dollar exchange rate remained largely stable, closing at 1,338.6 won per dollar, down 1.3 won from the previous day.
