More than 360,000 South Korean margin accounts have reportedly been forcibly liquidated during the stock market’s leverage-driven reversal, with Citi estimates placing 62% of the affected accounts among investors under 35.
Goldman Sachs separately estimated that more than 1.2 million leveraged retail accounts had triggered margin calls by July 13, with between 320,000 and 360,000 fully liquidated. Those estimates predate this week’s two-session crash, when the KOSPI lost more than 15% and brokers accelerated the closure of undercollateralized positions.
South Korea’s margin loan balance reached a record 38.63 trillion won on June 24 before declining to 34.37 trillion won by July 15. Broader investor borrowing, including other forms of stock-backed debt, <a href="https://www.reuters.com/world/asia-pacific/i-couldnt-breathesouth-koreas-frenzied-stock-trading-exposes-margin-loan-risks-2026-07-20/" rel="noopener noreferrer nofollow">surpassed 60 trillion won at the end of May</a>.
The liquidation and age figures remain market estimates rather than a detailed account-level disclosure from South Korea’s financial regulators.

The KOSPI rebounded about 3% to roughly 5,831 on Thursday after Samsung Electronics reported record second-quarter profit, but the index remained almost 38% below its June peak of 9,385.59.
Wednesday brought a further decline after the index <a href="https://cryptoadventure.com/kospi-falls-8-as-july-loss-reaches-35-in-deepening-chip-rout/" rel="noopener noreferrer nofollow">fell 8% and pushed its July loss toward 35%</a>. The KOSPI dropped as much as 12.6%, triggered another 20-minute circuit breaker and closed 5.98% lower.
That followed Tuesday’s <a href="https://cryptoadventure.com/kospi-plunges-nearly-10-as-chip-rout-triggers-trading-halt/" rel="noopener noreferrer nofollow">10.84% collapse led by Samsung and SK Hynix</a>, when trading was also halted after the benchmark remained below the market-wide circuit-breaker threshold.
SK Hynix fell as much as 19% on Wednesday before closing down 9.6%, while Samsung dropped as much as 14% before trimming its loss to 5.2%. The two companies account for more than half of the KOSPI’s market value, allowing leveraged bets on memory-chip stocks to transmit directly into the wider index.
SK Hynix had already suffered a <a href="https://cryptoadventure.com/sk-hynix-crashes-15-4-in-biggest-drop-on-record/" rel="noopener noreferrer nofollow">record 15.4% one-day decline earlier in July</a> as investors reduced exposure accumulated during the AI-driven rally.
<h2 id="seoul-tightens-leveraged-etf-rules">Seoul Tightens Leveraged ETF Rules</h2>
South Korean authorities are introducing additional restrictions on single-stock leveraged exchange-traded funds after acknowledging that concentrated retail positions intensified the market’s volatility.
The proposed framework could cap an investor’s exposure to those products at 20% of total investment assets. Regulators will also raise trading costs, require simulated trading and prepare emergency powers for stabilizing markets during extreme price moves.
New listings and advertising for single-stock leveraged products have already been suspended. A separate rule raising the minimum cash deposit required to trade them from 10 million won to 30 million won takes effect on July 31.
