The Kospi index clawed back 1.5% on Monday to close at 5,137, only days after a circuit breaker froze trading in Seoul during one of the ugliest sell-offs the market has seen all year.
The bounce capped a wild few sessions for Korean investors. The Associated Press reported that the benchmark index rose 1.52% to 5,137.22, lifted by the very chipmakers that had dragged it into the mud, as Samsung Electronics gained 2.7% and SK Hynix jumped 3.9%.
It followed a brutal Friday. According to The Korea Herald, the Kospi had crashed 6.02% to 5,059.69 after plunging as much as 8.78% during the day to an intraday low of 4,911.28, its first dip below 5,000 in live trading since early February. The drop was steep enough to trip a circuit breaker that halted the market for a full 20 minutes.
The pain was concentrated in the two giants that have powered Korea’s artificial intelligence boom. Samsung Electronics ended Friday down 6.35%, leaving it worth roughly half its peak for the year, while SK Hynix tumbled 10.44%. Foreign funds have been relentless sellers, dumping around 10 trillion won of Korean shares across the week, and they carried on selling even as prices recovered on Monday.
Several forces collided to send Seoul into freefall:
- an overnight rout on Wall Street in AI and semiconductor stocks that spilled straight into Asian trading;
- fears that Democratic gains in the United States midterm elections could tighten the rules on new AI data centres;
- a mounting worry that sky-high valuations across the AI sector have simply run too far, too fast.
That final fear is the one keeping traders awake, because it goes to the heart of the story the whole market has been telling itself for two years.
The data-centre fear behind the fall
At the centre of the sell-off sits a very specific worry about where the money for artificial intelligence actually ends up. Investors are fretting that a Democratic-leaning Congress could slow the breakneck construction of the vast data centres that AI depends on, especially in states such as Texas, Georgia and Ohio where huge numbers are planned.
Not everyone thinks the panic stacks up. Lee Kyung-min of Daishin Securities argued that a complete halt to data-centre building is unlikely, putting the chance of fresh project suspensions at only 15 to 30%. To him and others, the slump looks more like an overdue reality check than the end of the boom.
The country’s brokerages have pushed back hard. “Both fears of a sharp decline in AI investment and a severe slowdown in the US economy are excessive at this point,” said Lee Jun-young of Eugene Investment and Securities.
Whether traders believe him is another matter, because confidence, once shaken, takes far longer to rebuild than it does to crack.
Why the Kospi index drop is felt in Britain
A crash on the other side of the world rarely stays there. The sell-off was born in New York and amplified in Seoul, and the same AI and tech-stock euphoria that has lifted everything from Korea’s chipmakers to the headline-grabbing electric-car futurists unveiling their halo models runs through British portfolios too.
Portsmouth And has been watching how a tremor that started on Wall Street lands closer to home. Plenty of UK pension savers hold global tech and index funds stuffed with the very American and Asian names at the eye of this storm, so the question gnawing at Seoul, whether the AI boom has peaked, is one that quietly matters to anyone in Britain with money in the market.
For anyone tracking it, the swings have been dizzying. The Kospi has roughly doubled during the AI rally, so even Friday’s violent drop left the index far above where the boom began, which is partly why opinion is so split over whether this is a healthy correction or the first real crack. You can follow how these global money stories keep rippling into everyday UK business and world news as they unfold.
For now, Monday’s bounce has steadied nerves in Seoul. Whether it marks the bottom or merely a pause before the next drop is the one question no analyst there seems willing to answer with any real confidence.
