South Korean stock market starts August on a down note; regulatory authorities seek "emergency action authority"

原文:韩国股市8月“开门黑”,监管机构谋求“紧急行动权限”

Summary of Key Points

The South Korean stock market has recently experienced rollercoaster-like fluctuations: on the first trading day of August, it plummeted by 5.13%, and since July, its market value has evaporated by nearly the equivalent of the country's annual GDP. The core cause of this crisis is the hasty introduction of single-stock leveraged ETFs (which amplify both gains and risks). Retail investors have become the main victims due to excessive speculation. Regulators have urgently implemented several measures to reduce leverage, but the effectiveness of these actions has divided international investment banks. Currently, there are plans to amend the law to grant regulators more flexible emergency intervention powers. Kim Yong-ban, the head of the presidential office's policy division responsible for pushing the launch of these leveraged ETFs, is also facing criminal charges.

1. A Dark Start for the Stock Market: Sharp Index Drops and Emergency Measures

On August 3, the South Korean stock market began with a disastrous performance—the KOSPI index closed down by 5.13%, marking the largest single-day decline in recent times. Even more severe was the situation on the KOSDAQ (the country's tech stock market), where the exchange activated a "sidecar mechanism" due to the rapid drop, temporarily suspending automated trading for five minutes to prevent further declines caused by mechanical selling.

Leading chip companies, such as Samsung Electronics and SK Hynix, suffered the most, with their shares falling by over 8% during the session, dragging down the entire semiconductor sector. The flow of funds was also noteworthy: foreign and local institutions were selling stocks in large quantities, while retail investors were still trying to "buy at bottom prices" (although this may be very risky, as institutions understand market signals better than individual investors).

2. Leveraged ETFs: The Trigger for the Crisis

Many people may not understand what leveraged ETFs are. Simply put, they are a form of "borrowing money to invest in stocks, thereby magnifying potential profits and losses." For example, a 2x leveraged ETF means that if the stock market rises by 1%, you earn 2%, but if it falls by 1%, you lose 2%, doubling your risk.

The problem arose from South Korea's hasty introduction of single-stock leveraged ETFs last year. Previously, investors could only buy index-based leveraged products; now, they can also invest in individual stocks with leverage. It is reported that Kim Yong-ban, the head of the presidential office's policy division, approved the early launch of these products last January, despite the financial committee's original plan to wait until the second half of the year. These ETFs led to rampant speculation among retail investors, who profited during market gains but suffered heavy losses during declines, creating a "negative feedback loop": falling markets forced investors to liquidate their leveraged positions, leading to further declines and more liquidations. Kim Yong-ban is now facing charges for alleged abuse of power and could potentially face imprisonment.

3. Regulatory Efforts to Stabilize the Market: From Emergency Measures to Legal Changes

To stabilize the market, regulators have taken aggressive actions since July:

  • July 16: Prohibited the issuance of new leveraged ETFs, restricted advertising, increased the minimum deposit requirement from 10 million Korean won to 30 million won (which can only be paid in cash, not with stocks), and reduced the trading unit size from 1 share to 20 shares, making it more difficult for retail investors to enter the market.
  • July 29: Limited the proportion of leveraged ETFs in retail investor portfolios to prevent them from betting all their funds on these products, and considered raising transaction fees to increase the cost of speculation.
  • Current Legal Changes: The current law requires a "beneficiary meeting" for any change in the leverage ratio (where investors who own the ETFs must vote). However, this process is inefficient, and regulatory responses have been slow. Therefore, there are plans to amend the law to allow regulators to directly reduce the leverage ratio from 2x to 1.5x or 1x in emergencies, and to introduce "flexible leverage" (where fund managers could set the leverage ratio between 1.1x and 2x daily based on market conditions).

4. Retail Investors as the Main Victims: Market Value Evaporating Nearly Equivalent to Annual GDP

The most affected were individual investors. Since July, the KOSPI market value has decreased by 2116 trillion Korean won, nearly matching South Korea's annual GDP of 2616 trillion Korean won. Many retail investors were attracted by the high returns offered by leveraged ETFs but lost all their savings during the market crash. For instance, if an investor bought a 2x leveraged Samsung ETF and Samsung's stock price fell by 8%, they would lose 16% of their investment. If they also used margin trading, they could face additional losses. Although previous regulatory measures were intended to protect retail investors, they were implemented too late, resulting in significant losses.

5. International Investment Banks' Views: Divided Opinions

International institutions have mixed opinions on South Korea's leverage reduction efforts:

  • JPMorgan Chase: Notes progress, as the size of leveraged ETFs has decreased from a peak of $50 billion to $17 billion, indicating some success in reducing leverage.
  • HSBC: Believes that the measures are not sufficient, as the reduction in ETF规模 is mainly due to the market's decline (asset devaluation) rather than retail investors exiting the market. Many leveraged funds remain unliquidated, and the market may continue to be volatile in the future.

In summary, the South Korean stock market crisis was caused by a combination of hasty regulatory innovation, retail investor speculation, and market volatility. While regulators are trying to fix the issues, the losses suffered by retail investors are already substantial.
