Domestic stock market adjustments have led to investor deposits falling below 100 trillion won. While available funds for the stock market are rapidly decreasing, the balance of margin trading, known as 'debt investment,' remains steady in the 30 trillion won range.
 
According to the Korea Financial Investment Association, as of August 11, investor deposits were recorded at 97.9289 trillion won, a decrease of 2.7891 trillion won from the previous trading day. This marks the first time investor deposits have fallen below 100 trillion won since February 13, when they were at 99.2735 trillion won. Compared to the all-time high of 139.6947 trillion won on June 4, this represents a decrease of 41.7658 trillion won, or 29.9%.
 
Investor deposits refer to funds held in securities accounts that have not yet been used for stock purchases, typically viewed as available cash for the stock market. A decline in these deposits can indicate a weakening buying power among individual investors, which may add pressure to the market amid foreign selling.
 
In contrast, margin trading has rebounded to the 30 trillion won level. As of August 11, the balance of margin trading was recorded at 30.3872 trillion won. The balance in the securities market was 23.7704 trillion won, while the KOSDAQ market accounted for 6.2683 trillion won. After dropping to the 27 trillion won range on August 3-4, the margin trading balance has shown an upward trend. However, it remains 8.2456 trillion won, or 21.3%, lower than the record high of 38.6328 trillion won on June 24.
