South Korea Stock Market Leverage Massacre: Up to 460,000 Accounts Forced Liquidation, Retail Investors Lose Everything, Some Even Lost Their Pension
```
Leverage waits for no one.
On Monday, South Korea's KOSPI plunged nearly 9% in a single day, triggering the circuit breaker for the seventh time this year. Many retail investors stared at the red numbers on their screens, no longer pondering "how much they've lost," but instead asking a more urgent question—is there enough money left to get through the next margin call?
I. Forced Liquidation Wave: 425.8 Billion KRW Cleared With One Click
The intensity of this round of leveraged wipeout can be felt from one set of figures.
According to South Korea's "Maeil Business Newspaper," from July 1 to 10, the actual amount of forced liquidation for unsettled brokered trades reached 425.8 billion KRW.
On July 9 alone, 142.2 billion KRW of stocks were forcibly sold, with a forced liquidation rate as high as 10.2%, the highest since June 9; on July 10, another 81.6 billion KRW of sell orders flowed into the market.
The mechanism for margin trading in Korea is: if an investor has insufficient settlement funds, they can borrow short-term from the broker, typically for three trading days. If they fail to pay by the deadline, the broker will forcibly liquidate the position the next trading day—often at a discounted price, leaving retail investors powerless.
More dangerously, forced liquidation itself triggers new forced liquidations.
Account losses → triggers margin shortage → broker forced sell-off → further price drops → risk exposure of more accounts expands → new round of forced liquidation. This is the spiral retail investors fear most; losses aren't slowly expanding, but are being accelerated by leverage.
According to data from the Korean Financial Supervisory Service and Korea Financial Investment Association, on July 13 the total amount of forced liquidation across the market hit 344.2 billion KRW, the largest amount this year.
More than 1.2 million leveraged retail accounts hit the margin call line, with an estimated 320,000 to 460,000 accounts forcibly liquidated by brokers, principal wiped out, and some retail investors even left in debt.
II. Eight Out of Ten Lose: The Index is Up, but Retail Investors Don't Make Money
The South Korean stock market appeared strong in the first half of the year. The KOSPI rose 69% in the first half, and market enthusiasm was high.
But this stellar report card is just a fig leaf for most retail investors, unable to cover their losses.
According to "Maeil Business Newspaper" analysis of data from a major brokerage's retail customers, from the start of the year to the end of June, an average of 73.45% of investors lost money in the 50 Korean stocks with the most retail buying. Even more extreme, in 25 out of these 50 hot stocks, more than 80% of investors were losing money.
"Loss-making investor" is defined very simply—a person whose average buy price is higher than the closing price at the period's end.
The index is up, but retail investors are losing money. This seemingly contradictory phenomenon is actually not surprising.
The average return for these 50 stocks in the first half was about 20.5%, but returns were highly concentrated in a few leaders. The five stocks with the highest return averaged 198%, creating a strong illusion of profits. Retail investors mostly chased the hottest stocks after the surge. When the index began to correct, they missed the rise and caught the fall.
More critically, retail investors tend to buy in a lump sum rather than building positions in batches. In a highly volatile market, it's difficult to judge peaks and troughs, so heavy one-time entry makes the chance of buying at a high much greater.
III. Leveraged ETF Disaster Zone: SK Hynix Drops 31% in One Day, 6 Trillion KRW Market Cap Vaporized
The most concentrated, brutal losses for retail investors happened in two-times leveraged ETFs tied to Samsung Electronics and SK Hynix.
KOSPI broke through 7,000 and 6,900 points intraday on Monday, with all 14 single stock leveraged ETFs hitting new lows.
Take SK Hynix for example: "KODEX SK Hynix Single Stock Leveraged ETF" plunged to 14,835 KRW intraday, down 66.6% from the high of 44,385 KRW on June 23; closing down 31.46% in one day. Samsung Electronics had similar results: "TIGER Samsung Electronics Single Stock Leveraged ETF" fell to 12,035 KRW, down 60.4% from its high.
The underlying stocks fell heavily—Samsung Electronics dropped 10.70%, SK Hynix fell 15.37%—but leveraged products tracking double the volatility amplified the impact: Samsung Electronics related leveraged ETFs fell 22% to 24%, SK Hynix related products fell 31% to 33%.
The market cap evaporation was glaring: The 16 single stock leveraged products (including two inverse ETFs) shrank from over 16 trillion KRW on June 25 to 9.6536 trillion KRW, a drop over 6 trillion KRW.
On July 13, Goldman Sachs Sales and Trading noted in a report for institutional clients that these products' gamma rebalancing accounted for 62% of local institutional net selling that day—retail investors' leveraged products have become amplifiers in the market's cascading declines.
According to market estimates, retail investors lost a total of 2.15 trillion KRW (about 12 billion HKD) in leveraged trading over the past month. Among liquidated accounts, young retail investors aged 20–30 accounted for 62%.
IV. Ammo Running Out: Margins Evaporate 20 Trillion KRW in One Month
Retail investors have not only lost money, but their ammo for making margin calls is nearly exhausted.
According to Chosun Biz, South Korean investors' margin balances dropped about 20 trillion KRW in a month to 107.1279 trillion KRW. Credit financing balances fell from 38.6328 trillion KRW on June 24 to 36.6336 trillion KRW on July 9.
Buying is receding as well.
From July 1 to 10, the daily net buying by retail investors averaged 1.494 trillion KRW, down 42.4% from June’s 2.5956 trillion KRW; total retail net buying dropped from 54.5084 trillion KRW in June to 10.5384 trillion KRW, a fall of 80.7%.
The new money that was pouring in as of May had slowed noticeably since mid-June.
According to interviews by Chosun Biz with multiple brokerage private banking advisors, new investment consulting used to be fully booked, but now there is almost no new business.
Especially for clients who entered between May and June, they didn’t have a chance to make a profit before facing sharp volatility. The most common question now is: "Is the semiconductor cycle over, should I sell now?"
Another brokerage staff said, clients with floating profits are mostly waiting for a rebound, but new money is almost non-existent.
V. Stock Market Losses Turn into the Cost of Living
The pain in the account has already shifted from numbers to changes in life plans.
According to Korean media, a 39-year-old office worker put about 80 million KRW of house-buying funds into semiconductor stocks and leveraged ETFs last month, and recently suffered a floating loss of about 18 million KRW. He says that if stock prices don't recover, his marriage may have to be postponed.
Another 57-year-old worker withdrew 150 million KRW of retirement savings early to buy Samsung Electronics and SK Hynix, among others, and recently suffered a floating loss of over 30 million KRW. He said he expected returns to be higher than bank interest, but suffered heavy losses due to lack of understanding of bottoms and investment methods.
Other retail investors have posted SK Hynix account losses of over 2.1 billion KRW.
This is the real-life version of "Even money for margin calls is gone." Not everyone is talking about recouping losses; many have to answer a more imminent question—can they survive another round of decline?
VI. Funds Quietly Withdraw, "No One Talks About Stocks Anymore"
The retreat in retail investor sentiment is clearly visible in ETF data.
At the beginning of July, net assets in Korea's domestic equity ETFs were 304.8371 trillion KRW, down 25.8085 trillion KRW (7.8%) from June's 330.6456 trillion KRW, marking the first decline since March.
Meanwhile, fund preferences are quietly changing.
Previously, personal funds were concentrated in semiconductor leveraged ETFs, but recently "TIGER US S&P500" became the fourth largest retail net buy, and "KODEX US Nasdaq 100" ranks seventh. Retail investors began to net sell Korean semiconductor ETFs—"HANARO Fn-K Semiconductor" was net sold 274.7 billion KRW in one week, topping all ETF net sales.
Korean media summed up this cooling as "no one talks about stocks anymore." More accurately, retail investors are not fully leaving the market, but are withdrawing from the most crowded, most volatile, and most margin-call-prone areas.
VII. Government Emergency Action: Preventing Suicides Due to Economic Crisis
At the government level, Korea's Financial Services Commission submitted the "Suicide Prevention Measures for Families in Economic Crisis" at a Cabinet meeting on July 14.
The figures are shocking: suicides in Korea caused by economic issues rose from 3,089 in 2015 to 4,398 last year, and continue to climb.
Additionally, the government will launch a nationwide debt counseling hotline (1375) in October, offering one-stop services for debt adjustment, personal bankruptcy applications, etc.; it will also expand physical support networks and develop an "economic crisis family identification model" to integrate financial and non-financial data for proactive crisis group identification.
Financial regulators will convene top-level "F4 meetings" to urgently discuss measures such as raising margin requirements for leveraged products, limiting daily price fluctuations, and tightening suitability reviews.
Epilogue
Jung In Yun, CEO of Singapore-based hedge fund Fibonacci Asset Management, captured the deepest wound of this leverage rout:
"Many retail investors seem to treat leveraged ETFs as long-term investments rather than short-term trading tools. Huge losses may dampen their willingness and ability to buy semiconductor stocks, making market rebounds more reliant on foreign institutional funds."
The most direct blow to retail investors from this round of KOSPI declines is not the index pullback itself, but the breach of cash flow.
Losses can wait to be repaired, but leverage does not wait for anyone.
For many retail investors, the biggest risk right now is not missing the rebound—but not surviving to break even.
