KOSPI volatility since July has sharply depleted investor cash held at
brokerages, shrinking a key liquidity pool, the Korean Financial Investment
Association (KOFIA) said. Average daily investor deposits fell by nearly 20 tln
won month‑on‑month last month and are about 10 tln won lower than in March, when
a US‑Iran military clash triggered a market correction. Deposits stood at
104.6584 tln won as of the 30th of last month (the day KOSPI hit a local low),
down from a record 139.6948 tln won on June 4 — a drop of more than 35 tln won
in roughly two months. Investor deposits are funds in securities accounts used
to buy stocks; the decline reduces potential buying power and weakens market
supply‑demand momentum.
