South Korea's market got its first quiet-ish day of the week on Thursday — and even that took work. After back-to-back circuit-breaker halts, the Kospi steadied but still slipped about 1.2%, its third straight decline, leaving the index roughly 40% below June's record and on track for the largest monthly drop in its history. Total damage since the peak: about $2 trillion in market value, per Reuters.

The government has now acted. The question being asked in Seoul — loudly, and with funeral wreaths — is whether it acted well enough.

What the new rules do (and don't do)

Following Wednesday's emergency meeting of Korea's top financial authorities, regulators announced caps on individual investment in single-stock leveraged ETFs and higher trading costs for those products, alongside a 24-hour market monitoring system. These are the products — launched only in May — that amplified both the rally and the crash by forcing mechanical selling as prices fell.

Korea's new rules cap <em>who can buy</em> and <em>trading costs</em>, but leave the leverage multiplier itself untouched — the key difference from Hong Kong's approach.

But analysts told Reuters the measures may not go far enough, and the critique is instructive. The Korean rules limit who can buy and at what cost — they don't touch the scale of the leverage itself, which is what Hong Kong's regulators capped this month. Existing holders aren't required to unwind anything, and similar leveraged products listed in New York and Hong Kong sit outside Seoul's reach entirely. One Seoul research head called the cap hastily announced; a Citi economist argued a market stabilization fund would do more. In short: the fuel is still in the tank; the rules mostly narrow the fueling line.

The anger is now political

The human dimension turned raw this week. About 40 funeral wreaths appeared on the sidewalk outside the National Assembly — a Korean protest tradition — with ribbons reading "slaughtering retail investors." The finance minister apologized in parliament for launching the products "without careful consideration," and calls for tougher action, including a temporary trading suspension of the ETFs, are now coming from within the ruling party itself. The people hurt most, Reuters reports, are late-arriving local retail investors — young people and pensioners, many trading with borrowed money.

The paradox at the heart of the crash

Here is the fact that makes this crisis a permanent teaching text: this same week, Samsung and SK Hynix — the two stocks at the center of the collapse — reported roughly ₩150 trillion (about $100 billion) in combined quarterly profit. Samsung's profit jumped nineteen-fold on AI chip demand. The market crashed anyway.

The disconnect: Samsung and SK Hynix reported roughly $100 billion in combined profit the same week their stocks collapsed. Strong fundamentals couldn't override forced mechanical selling from leveraged unwinds.

Nothing explains it better than the mechanics we covered in the emergency piece: leveraged unwinds sell because they must, not because business is bad. JPMorgan estimates that forced deleveraging is now largely complete — leveraged-ETF liquidations essentially done, hedge funds roughly 90% through — which is why some desks maintain rebound targets far above current levels. But Thursday's session shows the other side: light volume, foreigners still net sellers (about $13 billion in July), and investors who, as one US fund manager put it, see a logical limit to the fall but "don't want to try to catch the falling knife."

The caveat stands: "the forced selling is nearly done" is an analyst estimate from banks whose clients are positioned for a rebound — not a fact. One steadier session repairs nothing after a 40% decline.

Why this matters to YOU

Rules made in a panic have gaps. Korea capped buyers, not leverage — a distinction that will decide whether volatility actually falls. When regulators respond to a crisis, read what the rules don't cover.

Profits don't stop forced selling. A 19-fold profit jump couldn't hold up a stock being mechanically sold. Until you can tell price-driven selling from forced selling, crashes will always look irrational.

Forced selling happens when investors must sell due to margin calls, automatic stop-losses, or fund redemptions — regardless of fundamentals. Price-driven selling happens when investors choose to sell because they believe the asset is overvalued. In Korea's case, forced selling from leveraged products overwhelmed any rational price discovery.

When prices fall, leveraged ETFs must sell to maintain their target ratio (e.g., 3× daily movement). This selling pushes prices lower, triggering more forced sales in a self-reinforcing loop — regardless of whether Samsung's earnings are up 19× or down.

Leverage is a systemic risk, not just a personal one. The wreaths outside parliament were laid by individuals — but the products they bought moved an entire national market. Korea has now written the definitive cautionary tale about leveraged ETFs, eleven weeks after listing them.

The full arc starts with the Kospi emergency update and continues here. Next checkpoints: whether the curbs slow the volatility, and month-end data on the record July decline.

Frequently asked questions

What new leveraged-ETF rules did South Korea announce?

Regulators capped individual investment in single-stock leveraged ETFs, raised trading costs, and introduced round-the-clock monitoring, but did not directly cap the products' leverage.

Why did the Kospi keep falling despite record chip profits?

Leveraged products and other investors were forced to sell as prices fell, so mechanical deleveraging overwhelmed strong company fundamentals in the short term.

Is forced selling in South Korea finished?

Some bank analysts estimate that most of the deleveraging is complete, but that remains an estimate; foreign investors were still net sellers and one quieter session does not establish a durable bottom.
