Asia's Next Leverage-Driven Crash May Emerge Beyond Korea
Many investors in Asia borrowed money to buy shares, especially technology stocks.
Borrowing can make profits bigger, but it can also make losses happen faster.
In South Korea, technology shares fell and many investors could not repay their loans.
Brokers then sold their shares automatically, causing prices to fall even more.
Similar borrowing has increased in China, India and Japan.
China appears especially exposed because its margin debt is large compared with its stock market.
The risks differ by country because investors are borrowing to buy different kinds of companies.
Regulators have introduced safeguards, but investors may still face large losses if prices fall quickly.
South Korea’s KOSPI fell 39% from June 22 to July 30 after leveraged retail positions unwound.
Margin balances have surged in India, China and Japan, with China’s balance reaching 2% of market capitalization.
China’s margin balance is 8% above its previous May 2015 peak, which preceded a 48% Shanghai Composite decline.
Leverage is concentrated in technology stocks in China, Japan and South Korea, while Indian borrowing is concentrated more heavily in smaller companies.
Regulators in South Korea, India and China have introduced measures to limit margin-related risks, but the article says these risks remain.

A sharp decline can trigger margin calls and automatic liquidations, producing a self-reinforcing market selloff even without a major change in company fundamentals.
Regulation May Limit Contagion
Regulators have raised requirements, restricted some leveraged products and limited certain uses of securities-backed loans, reducing the risk of an unchecked buildup.
