South Korea Tightens Leveraged ETF Rules, Raising Cash Minimum 10-Fold to 30 Million Won
3 articles · Updated · CNBC · Jul 20
Summary
South Korea on Thursday required investors to post at least 30 million won in cash to trade single-stock leveraged ETFs, up from an effective 3 million won, after violent swings in Samsung Electronics and SK Hynix.
Retail investors had poured a net 14 trillion won into the products since their May 27 launch, but the KODEX SK Hynix Single Stock Leverage ETF has fallen about 70% from its June peak and roughly 50% from debut.
That reversal has exposed how leverage amplified South Korea's AI-chip rally: leveraged Korea ETF assets reached about 30% of the 25 largest Korea-focused funds by June, double the share at the start of 2026.
The Bank of Korea and Oxford Economics had already warned that record retail leverage and concentrated semiconductor bets could magnify volatility, even if they were unlikely to pose a systemic financial threat.
Analysts say the unwind may not be over, with memory-chip stocks still seen as a crowded global trade and any moderation in hyperscaler spending likely to pressure semiconductor positions further.
Will Seoul's new rules save its stock market, or have they trapped an army of retail investors?
Is the Korean AI chip market a falling knife, or a historic buying opportunity for savvy investors?
