Individual investors in South Korea accumulated record leveraged stock positions in Q2 2025, with total leverage reaching approximately 62 trillion won, but July market volatility triggered a wave of forced liquidations and a 5 trillion won decline in credit balances. The aftermath stems from rapid KOSPI fluctuations in July, including circuit breaker activations and sharp swings in major semiconductor stocks like Samsung Electronics and SK Hynix, which caused collateral values to collapse for leveraged accounts. Financial authorities and industry analysts are monitoring risks that extend beyond securities firms to include rising bank loan delinquencies and broader financial sector soundness concerns, particularly after the Bank of Korea raised the base rate to 2.75% on July 16.
Credit Trading Balance Reaches Record 35.9 Trillion Won in Q2 2025
According to the Korea Financial Investment Association, the credit trading balance averaged 35.9418 trillion won daily in Q2 2025, marking an all-time high on a quarterly basis. Including securities lending of 25.9666 trillion won, the total daily average leverage investment scale reached 61.9084 trillion won, effectively amounting to 62 trillion won. The credit balance peaked at 38.6328 trillion won on June 24, reflecting maximized borrowing by individual investors during the semiconductor-led bull market.
July KOSPI Volatility Triggers 142.2 Billion Won in Forced Liquidations on July 9
The market direction shifted in July. The KOSPI experienced rapid declines and surges in a short period, creating the most unfavorable environment for leveraged investors. Circuit breakers were triggered multiple times this month, and volatility expanded in top-capitalization semiconductor stocks including Samsung Electronics and SK Hynix, shaking the entire index. The KOSPI fell below 7000 intraday before recovering above 7000, continuing a roller-coaster market pattern. On July 9 alone, forced liquidation volume surged to 142.2 billion won, with the cumulative scale in July growing rapidly. Brokerage account receivables exceeded 1.4 trillion won, and the ratio of forced liquidations to receivables rose sharply compared to the beginning of the year.
Credit Balance Declines 5 Trillion Won from June Peak
With individual funds concentrated in leverage products related to Samsung Electronics and SK Hynix, the simultaneous plunge in both stocks led to successive forced liquidations of accounts with collapsed collateral values. As a result, the credit balance, which had reached an all-time high, declined approximately 5 trillion won from its peak to the mid-33 trillion won range. Investor deposits also dropped by over 30 trillion won in one month.
Household Loans Increase 7.6 Trillion Won in June Amid Stock Investment Surge
Concerns are spreading from securities firms to the banking sector. According to the Bank of Korea, household loans at banks increased by 7.6 trillion won at the end of June compared to the previous month, the largest increase in 1 year and 10 months. Other loans centered on unsecured credit loans increased significantly, with the Bank of Korea analyzing that the expansion of individual stock investment was one of the main backgrounds. The burden on borrowing investors has intensified further with the base rate hike.
Bank of Korea Raises Base Rate to 2.75% on July 16
The Bank of Korea's Monetary Policy Committee raised the base rate to 2.75% annually on July 16. Securities firm credit rates also reach around 9% annually on a long-term basis. As funding rate increases are reflected, the structure inevitably leads to simultaneous increases in investment losses and interest burdens. Industry observers note that the key variable to watch going forward is the "recovery rate" rather than simply the credit balance size. If collateral disposal through forced liquidations during stock price plunges fails to fully recover loans, securities firms' uncollectable receivables increase, and if bank unsecured loans deteriorate, this could lead to financial sector soundness burdens. While leverage increases trading volume in bull markets, in volatile phases it can amplify market volatility through a vicious cycle: forced liquidations → stock price decline → collateral value impairment → additional forced liquidations.
This debt investing cycle extends beyond individual investor losses to connect securities firm receivables, bank delinquency rates, and financial sector soundness, suggesting potentially greater ripple effects than in the past. A risk management official at a securities firm stated, "The key is not the credit balance reduction itself, but how much uncollectable receivables increase even after collateral disposal," adding, "For the time being, we need to watch both the pace of leverage reduction and delinquency rate trends together."
