Kospi Crash Wipes Out Korean Retail Tech Bets
SkimNews Take
Margin-fueled retail buying in Korean tech shares turned those same 1.2 million leveraged accounts into forced sellers during the reversal — a feedback loop where the leverage that amplified the rally became the mechanical pressure on its unwind.

- Kospi index surged above 9,000 points in mid-June before plunging to roughly 5,500 within weeks, with the June-August correction described by BNY's Wee Khoon Chong as comparable to drops during Covid-19 and the 1997 Asian financial crisis
- Yongjoon Kim, a bank worker getting married later this year, lost 20 million won ($14,000) in July on tech investments earmarked for a home purchase, saying the money's gone and he'll have to work harder to make it up
- Woongsa Kim invested half his work bonus in SK Hynix at the start of the year; the stock quadrupled before most gains evaporated, leaving holdings at roughly half their peak value of about 300 million won
- Chanyong Park shifted profits from Nvidia shares (up more than 1,000%) into SK Hynix, losing around $10,000 and now questioning whether he can still afford to leave his marketing job in October to launch his own business
- By the end of July an estimated 1.2 million South Korean personal investor accounts had faced margin calls — roughly one in every 30 working-age adults in the country — driven largely by leveraged bets on AI-linked chipmakers
- Concerns over massive AI infrastructure spending triggered the sell-off, and tech-heavy Japan's Nikkei 225 has begun moving in tandem with the Kospi, though Societe Generale's Frank Benzimra says broader diversified markets like the US are unlikely to see similar volatility
Why it matters: An estimated 1.2 million Korean retail accounts — about 1 in 30 working-age adults — faced margin calls in a single quarter after piling leveraged bets into AI-linked chipmakers like SK Hynix and Nvidia proxies. That concentration of speculative leverage in one country turned an AI-spending correction into a mass retail-investor wipeout, a pattern that more diversified markets like the US appear insulated from but Japan's Nikkei is beginning to mirror.
