South Korea Reinstitutes Ban on Short-Selling Amid Market Uncertainty

In a decisive move to curb market volatility and safeguard investor interests, South Korea has reinstated a ban on short-selling of stocks, effective from Monday, with a planned reassessment in June 2024. This intervention targets a persistent imbalance between institutional and individual investors and aims to clamp down on illegal trading activities by foreign banks, particularly amidst global market upheaval and localized economic concerns.

Details of the Short-Selling Ban

  • Duration and Scope: The prohibition on short-selling will cover all stocks listed on South Korean exchanges until at least the end of June 2024.
  • Objective: The Financial Services Commission (FSC) seeks to correct the unfair advantage institutional investors hold over retail investors.
  • Market Conditions: The ban responds to a mix of “growing external uncertainties” that stress the domestic markets, including international conflicts and economic slowdowns.
  • Enforcement: A new investigative team will target illegal short-selling practices, especially the persistent issue of naked short-selling.

Understanding the Short-Selling Controversy

The Rationale Behind the Ban

Short-selling, the practice of selling borrowed shares in anticipation of buying them back at a lower price, is a common trading strategy. However, the FSC Chairman, Kim Joo-hyun, announced at a press briefing that the current market instability made it crucial to stop short-selling to “maintain fair trading discipline.” This measure addresses the longstanding concern that major foreign investment banks have consistently engaged in practices deemed unfair to other market participants.

Previous Measures and Market Impact

Initially imposed in March 2020 during the market meltdown triggered by the COVID-19 pandemic, the ban on short-selling was meant to be a six-month emergency response. However, it extended to become the world’s longest ban of its kind, only partially lifted more than a year later for large-cap stocks in the KOSPI200 and KOSDAQ150 indices.

Actions Against Naked Short-Selling

Naked short-selling, selling shares without confirming their availability for borrowing, has been a particular area of concern. The FSC has resolved to root out such practices, already sanctioning several foreign entities, including two Hong Kong-based investment banks with substantial fines.

Reforms and International Considerations

System Reforms

The government is set to overhaul the system to prevent further instances of illegal trading. These changes are anticipated to pave the way for a more equitable and transparent trading environment, with real-time prevention measures against illegal practices.

International Standing

South Korea’s market classification by global index providers like MSCI could be affected by the resolution of the short-selling regulatory issues. The status upgrade to a developed market is contingent upon establishing a stable and fair trading landscape, which current regulations strive to achieve.

Future Review and Monitoring

In addressing the imbalance between retail and institutional investors, the FSC’s strategy includes not only a temporary ban but also a future review of the market’s condition. Come June 2024, the authorities will scrutinize market activities to decide if lifting the ban is warranted based on an improved trading environment. This future assessment underscores South Korea’s careful approach to market regulation—a balancing act between protecting domestic investors and fulfilling its international obligations as a burgeoning financial hub.


The reinstatement of the short-selling ban reflects South Korea’s commitment to ensuring market stability and fairness among investors. With plans to enforce stringent measures against illegal activities and a review slated for June 2024, the country demonstrates its resolve to maintain a balanced and orderly market. Investors and market watchers are keenly observing the impact of these regulations, hoping for positive outcomes that could include South Korea’s ascension to developed-market status by MSCI.

This trading strategy, while legal under specific regulations, carries the risk of significant controversy, especially in volatile markets where the perception of unfair advantage or market manipulation can lead to calls for stringent oversight. Click to know more.
