Investor Deposits Dip Below 100 Trillion Won as Margin Debt Climbs
Finance · Investment Banks/Brokers · yonhap_finance · 2026-08-27
Investor deposits in South Korean markets have fallen below 100 trillion won, while margin trading debt has risen to 33 trillion won, signaling increased leverage.
What Happened
Decline in Deposits: Investor deposits, a key indicator of market liquidity, fell to 98.9 trillion won as of the 26th, dropping below the 100 trillion won threshold. This marks a reversal from the peak of 106.5 trillion won recorded just two weeks prior.
Rise in Margin Debt: Conversely, margin trading balances—a proxy for retail 'debt-fueled' investing—climbed to 33.1 trillion won, marking the first time in a month that the figure has exceeded the 33 trillion won level. This represents seven consecutive days of growth since early August.
Shifting Investor Sentiment: The combination of shrinking cash deposits and rising margin debt suggests that retail investors are increasingly relying on leverage to maintain market exposure. The trend reflects frustration with the KOSPI's prolonged stagnation in a trading range.
Short-term Risks: Short-term margin trading also saw an uptick, reaching 1.15 trillion won. While forced liquidations remain at a relatively low 1.3% of total margin debt, the shift toward higher leverage highlights growing risk appetite amid market uncertainty.
