South Korea’s Regulators Accidentally Triggered a 30% Small-Cap Rally
South Korea’s financial regulators wanted to calm a volatile stock market as they cracked down on leveraged ETFs. However, they have made it more chaotic instead.
Crackdowns on leveraged ETFs tied to Samsung Electronics and SK Hynix, which required retail investors to post higher cash deposits, did not cool speculation. Retail money rotated en masse into Kosdaq small caps, which have now surged 30% from their July 30 low.
How Restricting Chip ETFs Sparked a Kosdaq Surge

Park Wooyeol, a global ETF analyst at Shinhan Securities, described the shift plainly. “We are seeing more money flow to Kosdaq, particularly today,” he said. “Volatility-loving retail investors who have moved to the single-stock leveraged ETFs are expected to make a comeback to the Kosdaq.”
An AI-driven selloff had already sent the Kospi plunging nearly 40% from its June peak to a late-July low, triggering forced liquidations and unwinding billions in margin loans. BeInCrypto reported that the SK Hynix leveraged ETF collapsed 45%, with regulators admitting the products had amplified market swings.
When authorities then tightened cash deposit requirements, they did not account for where that speculative energy would flow next.
Kosdaq vs Kospi: Best Divergence Since the Year 2000
The Kosdaq surged last week while the Kospi slipped. The small-cap gauge is now on track to outperform the benchmark by its widest gap since the dot-com era.

Korea’s retail investors have a well-documented appetite for high-volatility trades that has shaped even its crypto markets, and BeInCrypto found that Bitcoin was posting lower volatility than the Kospi at the height of the AI selloff.
The traders now flooding into small caps are the same cohort that drove the chip ETF boom. Regulators remain one step behind.
Whether the Kosdaq rally has genuine legs depends on whether Korea’s AI selloff has truly bottomed. If this is just another venue for the same speculative cycle, the circuit breakers will keep tripping.
