Summary of Key Points
In the first half of 2026, the South Korean stock market (KOSPI) exploded in value, doubling before suddenly collapsing. A large number of retail investors, especially those aged 20-30 who had used high leverage, suffered massive losses exceeding 2 trillion Korean won, leading to social crises such as suicides and assaults. The government urgently introduced measures to prevent what was termed "economic suicide." South Korean retail investors' enthusiasm for the stock market is unprecedented globally: they account for 71% of market transactions, with an average of two trading accounts per person. They resorted to mortgaging homes and using credit cards to borrow money for stock purchases, and they were particularly keen on ETFs with a leverage of two times (which carry extremely high risks). The root causes lie in South Korea's highly rigid social structure—chaebols monopolizing resources, intense educational competition, soaring housing prices, and blocked pathways for social mobility. As a result, many young people either choose to give up on romantic relationships, marriage, and careers or gamble on the stock market as a last attempt to overcome their desperate circumstances.
The Stock Market's Wild Ride: From a Dream of Breaking 10,000 Points to a Series of Collapses
The KOSPI index soared in the first half of 2026, reaching a record high of 9,385 points in June, with everyone hoping it would break through 10,000 points. However, it then plummeted, and there were four market circuit breaks in July (a total of eight circuit breaks this year, compared to only 21 in the past 25 years). Retail investors suffered the hardest, losing a combined total of 2.15 trillion Korean won, with those aged 20-30 accounting for 62% of the victims. Some, following advice from internet celebrities, invested all their savings and, after losing everything, stabbed the celebrities; others committed suicide, prompting the government to enact the "Economic Crisis Family Suicide Prevention Measures"—the second time in the world such legislation has been introduced (the first was in Japan in 2006).
In short, when the stock market is rising, everyone thinks they can get rich; when it falls, they risk losing their lives, with young people being the biggest victims.
How Crazy Are South Korean Retail Investors?
South Korean retail investors are the dominant force in the market, accounting for 71% of transactions in May 2026 (compared to just 30% in the United States), with an average of two stock accounts per person. They use every available means to invest:
- The amount borrowed from securities firms ("financing balances") exceeded 36 trillion Korean won, a record high.
- They mortgage homes and use credit cards to cash out, with even the elderly selling their pension insurance for investment.
- Unsatisfied with regular stocks, they flock to buy ETFs on Samsung and SK Hynix with a leverage of two times (which can result in double losses if the underlying assets fall; for example, if the stock price drops 8%, the ETF might rise 50%). The trading volume of these ETFs once accounted for over 70% of the market.
Daily life reflects this frenzy: office workers hide in bathrooms to watch stock prices (bathrooms are always full at closing time), fried chicken restaurants become "lucky seats" because of Yoon Suk-yun's visit (people queue for three hours in hopes of making a fortune), and children receive stock accounts as gifts on Children's Day. Young people say they'll wait until they make big profits from stocks before getting married, while those who don't invest are called "poor losers," as if they've been abandoned by the times.
Why Do South Koreans Love Stock Trading So Much?
This behavior is driven by a rigid social structure:
- Chaebols monopolize resources: The top 30 chaebols account for 77% of GDP but only provide 10% of jobs. Four major chaebols (such as Samsung and Hyundai) control 40% of GDP and employ only 3% of the population. Ordinary people can only work in small companies with low salaries and few benefits, and starting a business is impossible against such giants (government resources are heavily favored by chaebols).
- Intense educational competition: Good jobs (with chaebols or as civil servants) are reserved for graduates from top universities like Seoul National University (admission rates are less than 2%). Families with average incomes can't afford to send their children there. Tutoring fees are the largest expense, high school students sleep only 3-4 hours a day, and over 70% repeat a grade; even graduates from prestigious schools often end up in part-time jobs.
- Housing prices crush young people: An apartment in Seoul's Gangnam district costs 1.2 billion Korean won (about 6 million RMB), and ordinary workers would need to save for 20 years to afford the down payment. Without parental support, they can only live in half-basements and fall into debt if they lose their jobs.
- Discrimination is widespread: Companies prefer fresh graduates, and those who start working in middle age have no opportunities. After having children, most women quit their jobs, earning 30% less.
For young people, not investing in stocks means certain poverty; however, there's a one-in-10,000 chance of turning things around through the stock market—a final struggle against hopelessness.
The Two Paths: "Lying Flat" or Taking Risks
Faced with this rigid society, South Korean young people fall into two camps:
- The Lying Flat Camp: They give up on romantic relationships, marriage, and children, sometimes even moving back to live with their parents. Basic needs are met (98% coverage of healthcare, affordable medical care), so lying flat seems the better option.
- The Risk-Taking Camp: They use all their money for high-leverage stock investments, betting their lives on a big payout. They understand the risks but see it as the only chance to escape poverty and buy a house before quitting their jobs. It's like moths flying into a flame—dying in the attempt is better than waiting for death.
These choices both reflect a protest against the society: either give up everything or risk everything.
The Paradox of a Long Life Expectancy and High Suicide Rates
South Korea has one of the longest life expectancies in the world (second only to Hong Kong and Japan), but suicide rates are also among the highest. Why?
- Long Life Expectancy: Low infant mortality, excellent healthcare (low out-of-pocket costs), and mandatory free health check-ups (high early cancer detection rates) ensure that most people won't die from illness or hunger.
- High Suicide Rates: The pressure of a rigid society leaves young people with no future prospects, and market collapses shatter their last hopes. For them, the pain of living is greater than the fear of death.
In summary, South Korea's stock market madness reflects young people's desperate gamble in a stagnant society: either try to change their fate through stocks or sink into despair. This financial crisis has just harshly exposed their hopeless reality.
