South Korea to Limit Leveraged Products Amid Crypto Market Volatility

South Korea's financial regulators are stepping in to curb the risks associated with single-stock leveraged products, a move that follows a period of market volatility and criticism. The Financial Services Commission plans to introduce individual investment limits, potentially capping investments at 20% of total funds and allowing for reductions in leverage ratios if deemed necessary. This action reflects concerns over the potential for excessive speculation and financial instability.

If the stock price rises by only 2%, you can make a 100% profit. On the downside, the principal melts away before it even becomes 2%.

Meanwhile, the global cryptocurrency market presents an even more extreme version of leverage. Platforms like Binance offer perpetual futures contracts on stocks, allowing investors to leverage positions up to 50 times their initial investment. A mere 2% price movement can result in a 100% profit, but a similar dip can wipe out the entire principal. The sheer volume traded is staggering, with SK Hynix futures alone seeing over $5.47 billion in trading on a single day.

The inherent dangers of such high-leverage trading were starkly illustrated by an incident on the decentralized exchange Hyperliquid. A trading error on a South Korean pre-market platform caused a single SK Hynix share to be priced at its lower limit. This erroneous data point was adopted as the benchmark price on Hyperliquid, triggering the liquidation of 960 accounts and a loss of approximately $57.4 million. The incident occurred just seven seconds after the pre-market opened, demonstrating the speed and unforgiving nature of automated trading systems.

The market for SK Hynix on Hyperliquid took this lower limit and used it as the benchmark price. As a result, 960 accounts that had bet on the stock price rising were liquidated.

While traditional futures contracts serve to hedge risks for producers and consumers, perpetual futures with extreme leverage and automated liquidation systems are viewed by critics as highly speculative instruments that amplify risk. Proponents argue they offer efficiency and cost savings by eliminating contract rollovers. South Korea currently lacks authorized channels for trading these products, and while domestic investors can access overseas markets, the extent of their participation remains unclear. The differing regulatory approaches and market structures highlight the distinct experiences of investors in domestic and international leveraged markets.

Perpetual futures eliminate the physical asset and the expiration date, adding high leverage. Unlike traditional markets where brokers typically demand additional collateral when a position lacks sufficient margin, these systems automatically liquidate a trader's position to protect the exchange's cash during rapid fluctuations.
