South Korea halts new single-stock leveraged ETFs, raises deposit requirements

South Korea approved single-stock leveraged ETFs in January. By mid-2025, regulators are already hitting the pause button.

The Financial Services Commission (FSC) is temporarily stopping the expansion of new single-stock leveraged ETFs and raising deposit requirements for leveraged semiconductor funds. The move comes after extreme volatility in products tied to Samsung Electronics and SK hynix, the two giants that essentially are the Korean stock market’s center of gravity.

From green light to yellow light in record time

The original approval back in January was supposed to be a modernization play. South Korean regulators wanted to keep domestic capital from flowing overseas to chase leveraged products already available on US exchanges. The logic was straightforward: if Korean investors were going to trade leveraged single-stock ETFs anyway, better to have them do it on home turf where local rules apply.

One ETF linked to SK hynix reportedly moved by 40% in a single day.

New guardrails for retail investors

The FSC isn’t just pausing new listings. It’s also tightening the rules around who can trade these products and how.

Investor protections now include a mandatory 1-hour learning session before trading. There’s also a deposit requirement of 10 million KRW, roughly $7,300.

The semiconductor factor

It’s not a coincidence that the products causing the most concern are linked to chip stocks. Samsung Electronics and SK hynix manufacture the high-bandwidth memory chips that power Nvidia’s data center GPUs. That makes them proxies for the AI trade, which has been one of the most volatile and momentum-driven themes in global markets.

The FSC approved these ETFs with leverage capped at 2x as part of efforts to modernize its financial markets and retain domestic capital, aligning with global ETF standards. However, the rapid expansion of these products has led to significant market instability and scrutiny from regulators, prompting a reevaluation of their potential long-term impact on the Korean stock market.
