[Data: Under high leverage in the stock market, 1 in every 30 adults in South Korea faces margin calls] Deep Tide TechFlow reports that on July 17, according to a report by CaiLian News Agency, Ioannis Blekos, Managing Director of Goldman Sachs' trading division, pointed out that as of July 13, over 1.2 million retail investors' leveraged credit accounts in the South Korean market had triggered margin call notifications, with approximately 320,000 to 360,000 accounts forcibly liquidated by brokerage firms. South Korea's population aged 15 to 64 is approximately 35.7 million, which means that roughly 1 in every 30 working-age individuals has received a margin call notification. According to the report, the margin balance of retail brokerage accounts has decreased by about 30 trillion Korean won, dropping to its lowest level since February 20 of this year. Meanwhile, the proportion of accounts receiving margin call notifications rose to approximately 5% last Friday, and it is expected to increase further as the sell-off in the semiconductor sector intensifies. It is reported that Thursday's capital flow data shows that foreign and domestic institutional investors are already withdrawing.
