South Korea weighs technical options for a temporary short-selling ban as stocks slide

July 30 — South Korea’s Korea Exchange (KRX) has recently reviewed the technical feasibility of deploying emergency measures during sharp market downturns, including a temporary ban on short selling and tighter daily price limits, Yonhap News reported. The KRX examined whether its systems could execute such steps and how long any required adjustments would take. Market sources stressed the work was limited to confirming technical readiness and does not indicate an intention to implement the measures. The exchange also assessed the possibility of cutting the current 30% daily price fluctuation limit to better restrain single-stock losses under extreme conditions. Earlier, the Ministry of Economy and Finance convened an emergency meeting on market conditions, saying volatility in Korea’s equity market has exceeded both global and historical levels. The ministry said it would maintain the highest level of vigilance and activate a joint 24-hour monitoring mechanism across relevant agencies. As the selloff has intensified, retail investors have increasingly called for a temporary short-selling ban. A related parliamentary petition reportedly collected about 10,000 signatures in two days, and some lawmakers have floated reviving the Securities Market Stabilization Fund. Brokerage analysts in Korea said a ban could help limit further downside while leveraged single-stock ETFs still need time to reduce exposure. At the same time, they cautioned that restricting short selling could run counter to Korea’s push for inclusion in the MSCI Developed Markets Index. In an official statement, the KRX said it has not received any government request for a short-selling ban, has not formally studied the measure, and cannot decide on such a step unilaterally.
