Domestic collateral ratio obligation waived for 3 months… Taiwan short-selling limit 30%→3%

South Korea’s government will temporarily waive securities firms’ obligation to maintain a 140% collateral ratio on margin loans for three months, while Taiwan will cut its intraday short-sale order limit to 3% of trading volume from 30% and raise the minimum short-selling margin to 130% from 90%, with both measures effective Nov. 9. The Korean relief applies to brokers’ collateral-ratio requirement, not investors’ repayment duties, so it does not eliminate margin calls or automatically halt all forced selling. The steps are aimed at easing strain in leveraged and short-selling activity as authorities respond to market volatility. Investors should watch whether the eased collateral rule reduces forced deleveraging in Korean margin accounts and whether Taiwan’s tighter short-selling terms curb intraday selling pressure.
