• The Korea Exchange has reviewed the technical feasibility of a temporary short-selling ban and tighter daily price limits as contingency measures to curb market volatility.
  • No decision has been made; officials describe the review as a routine contingency exercise.
  • Authorities remain on high alert amid sharp market declines, with retail investors calling for stronger stabilization measures.

Contingency Planning Underway

The Korea Exchange has examined the technical feasibility of implementing a temporary short-selling ban and tighter daily price limits, according to people familiar with the matter. The review, described by officials as a contingency exercise, has not resulted in any policy decisions. The exchange declined to comment on the specifics, but sources emphasized that the move is purely preparatory.

Market Pressure Mounts

South Korean stocks have experienced sharp declines in recent weeks, driven by global macroeconomic headwinds and domestic concerns over leveraged products and heavy concentration in chipmakers. The benchmark Kospi index has fallen more than 8% this month alone, triggering anxiety among retail investors who dominate trading volumes. Calls for market stabilization measures have intensified, with online forums and investor groups urging regulators to act.

Authorities are walking a tightrope. While short-selling bans and tighter price limits can reduce volatility in the short term, they also risk impairing price discovery and deterring foreign investment. Previous episodes in Korea and elsewhere have shown that such measures can lead to reduced liquidity and higher trading costs.

Regulatory Context

The review comes amid an already heightened regulatory environment. The Financial Services Commission has been probing illegal short selling and has imposed penalties on violators. In 2020, Korea implemented a temporary short-selling ban that lasted over a year, eventually lifting it in 2021 amid market recovery.

“Regulators are signaling they are prepared to act if needed, but they are also mindful of the negative side effects,” said a Seoul-based analyst. “The market is watching for any formal announcement.”

What’s Next?

The Korea Exchange is expected to continue monitoring market conditions. Any decision to impose restrictions would require coordination with the Financial Services Commission. In the meantime, traders are adjusting their strategies, with some expecting increased volatility in semiconductor and ETF-linked stocks.

Efforts to reach the Korea Exchange for comment were unsuccessful. The exchange said earlier this week it was “closely monitoring market conditions and will take appropriate measures if necessary.”
