Brokerage cash for stock purchases fell by more than KRW 35 trillion from a June record as July's KOSPI and KOSDAQ rout pushed investors toward bank deposits and away from leveraged chip bets.
Funds in South Korea shifted into safer assets as a broad July stock-market selloff, sharp losses in semiconductor shares and weaker liquidity reduced risk appetite. Time deposits at five major banks rose KRW 24.09 trillion from a month earlier to KRW 973.49 trillion at the end of July, while investor securities-account deposits fell from a record KRW 139.6948 trillion on June 4 to KRW 104.6584 trillion on July 30, according to Korea Financial Investment Association data released Aug. 3. The Korea Exchange said 1,859 of 2,645 KOSPI and KOSDAQ stocks declined between June 30 and July 31, with the KOSPI down 22.2% and the KOSDAQ down 21.4%, their worst monthly drops since October 2008 despite a record 17.91% rebound on July 31. Retail investors reversed from heavy buying in May and June to record selling in July as leveraged bets on Samsung Electronics, SK Hynix and related single-stock ETFs magnified losses and sent money back toward safer holdings.
