South Korea’s experiment with single-stock leveraged ETFs went from zero to disaster in about six weeks. Trading volumes in 2x leveraged products tracking Samsung Electronics and SK Hynix have collapsed after regulators effectively slammed the door on retail access, tripling minimum deposit requirements and halting new listings entirely.
From frenzy to free fall
When 16 single-stock leveraged ETFs tied to South Korea’s semiconductor giants debuted on May 27, retail investors piled in with net retail purchases surging past 13 trillion won, roughly $9 billion, in a remarkably short window. At their peak, these leveraged products accounted for up to 70% of total trading value in Samsung and SK Hynix stocks.
Then semiconductor prices turned south, and the 2x leverage did exactly what 2x leverage does in a downturn. One of the most popular products, the KODEX SK Hynix Single Stock Leverage ETF, fell nearly 70% from its June peak. Combined assets under management across leveraged ETFs cratered from approximately $50 billion to around $26 billion, a decline of nearly half.
Regulators step in, finance minister apologizes
By mid-July, South Korean financial authorities had seen enough. They implemented a temporary suspension on new leveraged ETF listings and tripled the minimum deposit requirement to 30 million won, approximately $20,000. The measures were explicitly designed to restrict access primarily to professional investors.
South Korea’s finance minister publicly apologized for an inadequate review of the ETFs’ risk profile before they were approved for launch. Daily turnover in these products has declined significantly since the regulatory barriers went up, as the combination of higher capital requirements and investor caution after steep losses has effectively drained liquidity from the market segment.
Why this matters beyond Seoul
For investors watching the broader Asian tech and semiconductor space, the AUM decline from $50 billion to $26 billion represents real selling pressure that has been removed from Samsung and SK Hynix stocks. When leveraged products accounted for 70% of trading value in those names, the forced deleveraging as those products shrank likely amplified the underlying stock declines.
South Korea has historically been one of the more aggressive regulators of crypto trading, having banned initial coin offerings in 2017 and implementing strict real-name trading requirements. The speed with which authorities moved to restrict leveraged ETFs suggests the same interventionist instinct could be applied to any financial product, traditional or digital, that generates outsized retail losses.
