South Korea's KOSPI surges past 7,000 led by Samsung and SK Hynix rally
South Korea's KOSPI index surged in mid-to-late September 2024, breaking through 6,900 and briefly touching 7,000 points, driven by strong gains in technology heavyweights Samsung Electronics and SK Hynix. The rally followed a record high on the Nasdaq and broad semiconductor advances. Japanese markets were closed for three consecutive days from September 21 due to national holidays.

Cross-source coverage
Common ground
- South Korea's semiconductor giants, Samsung and SK Hynix, are crucial to the global AI supply chain, especially for HBM memory used in Nvidia's chips.
- The KOSPI reaching 7,000 is a significant milestone driven largely by AI-related demand for semiconductors.
- Switching memory suppliers for Nvidia is not easy and takes 18-24 months, giving Korean manufacturers some short-term leverage.
- The debate highlights that Asian markets are becoming more independent and are not just following U.S. cues.
Points of contention
- Whether the KOSPI rally is a structural power shift or just a tactical, sector-specific bounce inflated by currency effects.
- If Korean chipmakers have real strategic leverage or are just well-paid suppliers dependent on a single customer like Nvidia.
- Whether the focus should be on market mechanics and geopolitics or on the human cost, labor conditions, and global injustices.
- If the chaebol system represents successful industrial policy or a feudal structure that concentrates wealth and power.
Blind spots
- The debate largely ignored the long-term demographic crisis in South Korea, including a very low birth rate and a declining number of engineering graduates.
- There was little discussion of the risk that China could build its own HBM capacity, which would reduce demand for Korean chips.
- The conversation did not address the governance issues within the chaebol system, such as the founding family's control with minimal equity.
WorldAttention’s read
The roundtable showed a clear split between seeing the KOSPI's rise as a sign of Asian economic power and viewing it as a risky, concentrated bet on AI. While everyone agreed that Korean chipmakers are essential right now, they disagreed on whether that gives them real leverage or just makes them vulnerable to shifts in demand and technology. The debate also revealed a tension between focusing on market data and geopolitics versus the human and social costs of the industry. Ultimately, the rally reflects a real boom in AI infrastructure, but its long-term meaning depends on factors like pricing power, customer diversification, and whether South Korea can solve its demographic and governance challenges.

South Korea's KOSPI briefly hits 7,000; Samsung surges 3.26% as Japan markets closed
On September 21, South Korea's KOSPI index opened sharply higher, briefly touching the 7,000 mark before retreating to trade up 0.71% at 6,943.29 points. The rally was led by technology and semiconductor heavyweights, with Samsung Electronics surging 3.26% to 269,500 won, nearing the 270,000 won level, while SK Hynix rose 1.08% to 1,877,000 won. The article attributes the buying momentum to easing selling pressure in the semiconductor and AI supply chain last Friday, as well as bargain hunting after the KOSPI's recent correction. It notes that the market has largely absorbed the short-term impact of the Federal Reserve's hawkish interest rate outlook and volatile international oil prices. Meanwhile, Japanese equity markets are closed for three consecutive days from September 21 due to Respect for the Aged Day and the Autumnal Equinox holiday. The report warns that if significant movements occur in international markets or the USD/JPY exchange rate during the closure, the impact could be reflected in a catch-up rally or decline when Japanese trading resumes on September 24.
