Summary of Key Points
Korean household debt has for the first time exceeded 2000 trillion won (approximately 9.73 trillion yuan), primarily due to retail investors borrowing heavily to trade stocks. During the second quarter, as the stock market soared, retail investors used credit loans and overdrawn accounts to leverage their investments, even purchasing high-risk leveraged ETFs. Subsequent market volatility led to a massive number of accounts losing all their principal. However, with the recent recovery in the stock market, retail investors have made a comeback, and even strengthened regulatory measures have not been able to stop them from buying into overseas semiconductor-related assets.
1. Household Debt Hits a Record: Borrowing to Trade Stocks as the Main Driver
The increase in Korean household debt did not come from housing loans (which only rose by 12.2 trillion won); rather, "other loans" increased more significantly (by 12.8 trillion won)—mainly unsecured credit loans and overdrawn accounts, which are essentially funds used for stock trading. The central bank explicitly stated that the rise in other loans is "mainly due to demand for stock investment." This marks the first time that the increase in loans for stock trading has surpassed housing loans, reflecting the retail investors' obsession with the stock market.
2. The Second Quarter Stock Market Boom: Retail Investors Borrowed Heavily
In the second quarter of this year, the Korean stock market (KOSPI) exploded, rising by 67.77% (the largest increase in 25 years), driven by strong demand for AI chips and rising prices of memory chips. Seeing opportunities for profit, retail investors flocked to the market:
- Account Opening Boom: 10 million new stock accounts were opened in the first half of the year, nearly matching the annual increase from the previous year; even middle-aged and elderly individuals withdrew their savings insurance funds to invest in stocks.
- Leveraged Gamblers: Retail investors bought leveraged ETFs on Samsung and SK Hynix at a two-fold leverage, using borrowed money to amplify their potential gains, but also suffering rapid losses. 92% of the shares in these ETFs were held by retail investors. How hot was the market sentiment? The KOSPI reached a high of 9385 points before experiencing a significant drop and a circuit breaker.
3. Market Volatility Leads to Massive Losses: Retail Investors Lose Everything
The good times did not last long. When semiconductor stock prices plummeted, leveraged accounts were subject to margin calls—meaning that if losses reached a certain level, brokers were forced to sell the investors' stocks to repay the debt. As a result, many retail investor accounts lost all their principal. Citibank estimates that these leveraged ETF investments resulted in at least 58 trillion won (about 290 billion yuan) in losses. The market was devastated, with many investors losing everything.
4. Strengthened Regulations Fail to Stop Retail Investors: They Start Buying on the Dip
Fearing that retail investors would suffer too much, the Korean government introduced several regulatory measures, such as requiring five rounds of simulated trading (each lasting one hour) before purchasing leveraged ETFs and setting a minimum investment requirement of 30 million won (about 20,000 yuan). However, these measures have not been effective:
- Domestic Market: Recently, the balance of margin funds for margin trading has risen from 27 trillion won at the beginning of August to 30.9 trillion won, on its way to challenging the historical high of 38.6 trillion won set at the end of June.
- Overseas Markets: Retail investors have also bought three-fold leveraged semiconductor ETFs in the United States (SOXL), investing $663 million in just two days, with a holding size of $6.56 billion; they have also bought into Japanese semiconductor stocks such as Murata Manufacturing and Tokyo Electron. Analysts believe that as long as the AI market remains strong, retail investors will continue to use leverage.
Conclusion: Why Are Korean Retail Investors So Passionate about Stock Trading?
The reason lies in their obsession with the AI industry; they believe semiconductors represent the future and are willing to take risks by borrowing money to invest. However, leverage is a double-edged sword—它可以 multiply profits when markets rise, but it can also lead to total losses when they fall. Although regulations aim to protect investors, they cannot stop their enthusiasm for chasing gains and cutting losses. Behind this madness lies the common desire of ordinary people to quickly make money through the stock market. Nevertheless, borrowing to trade stocks remains a high-risk activity, and the consequences of a market reversal can be devastating.
