South Korean regulators apologise as leveraged ETFs fuel market rout

Top financial officials in Seoul expressed regret over the approval of single-stock leveraged exchange-traded funds after the products exacerbated a severe sell-off in domestic equities.

South Korea’s finance minister and top financial regulator issued formal apologies on Wednesday following the introduction of single-stock leveraged exchange-traded funds. The products have been widely blamed for intensifying a severe rout across the country's equity markets.

Finance Minister Koo Yun-cheol told a parliamentary session he was sorry for launching the product without careful consideration. This followed a direct demand from a lawmaker for an official apology regarding the regulatory decision.

Lee Eog-weon, chairman of the Financial Services Commission, echoed these sentiments at a separate hearing. He told lawmakers: "As the ultimate authority responsible for the financial markets, we feel sorry that we have fallen short in properly meeting the public's expectations" over regulating the product.

The political backlash coincided with a dramatic plunge in domestic equities. The benchmark Kospi index plummeted by as much as 12.6 per cent during Wednesday's trading session.

The broader market decline was heavily concentrated in the technology sector. Massive losses in semiconductor giants Samsung Electronics and SK Hynix drove the index downward.

These two chip manufacturers alone account for nearly half of the Kospi's total market capitalisation. Their outsized weighting means that volatility in the semiconductor sector directly translates into severe systemic risk for the entire benchmark index.

The regulatory approval of these specific leveraged funds had already drawn criticism prior to the crash. South Korean retail investors had aggressively pumped capital into the new vehicles.

Most of these targeted funds were tied directly to Samsung Electronics or SK Hynix. Retail traders were betting on a continuous surge in robust demand for artificial intelligence technologies.

This sequence of events highlights the inherent dangers of introducing highly concentrated, leveraged retail products in markets dominated by a few mega-cap stocks. When retail enthusiasm for a specific theme like artificial intelligence meets leveraged exposure, the resulting unwind can trigger outsized market dislocations.

For investors and executives, the parliamentary apologies signal a potential shift in Seoul's regulatory posture. Future approvals for complex, single-stock derivatives may face much stricter scrutiny to prevent similar retail-driven volatility.
