Starting July 31, opening a new position in a single-stock leveraged exchange-traded product (ETP) in Korea requires 30 million won of cash sitting in the account as a base deposit. The previous bar was 10 million won, so the threshold has tripled. Energy Economy Daily reported that the start date, originally signalled for August, was pulled forward to the 31st of this month.
Mandatory pre-trade training expands from two hours to three on the same date. Raising the minimum trading lot from one share to twenty is scheduled for November, because brokerages need time to rebuild their order systems (Seoul Shinmun).
Three barriers went up at once for a reason: the losses recorded in the first half of July. Numbers first, structure second.
Three barriers, three different start dates
The changes cover deposits, training and lot size, and they do not all begin together. Deposits and training land at the end of this month; lot size waits until autumn. Separately, a deposit rule for overseas-listed leveraged ETPs has already been running since May.
| Item | Before | After | Effective |
|---|---|---|---|
| Base deposit | 10 million won | 30 million won (cash basis) | July 31 |
| Mandatory training | 2 hours | 3 hours, retake if the test is failed | July 31 |
| Minimum trading lot | 1 share | 20 shares | November (signalled) |
| Deposit for overseas-listed leveraged ETPs | None | 10 million won | In force since May 22 |
The overseas products came first. According to Herald Business, a 10 million won base deposit applied from May 22 to investors trading overseas leveraged ETFs and ETNs for the first time, and an advanced training requirement for single-stock leveraged and inverse ETPs — domestic and overseas — began the same day. This month's move stacks a threefold deposit increase on top of that.
Scope is the part worth checking. As reported, the increase squarely targets single-stock leveraged products, and the coverage reports do not spell out whether index-based products such as KOSPI 200 leveraged funds are treated differently. Whether a specific holding falls on one side or the other has to be confirmed at the product-code level in your brokerage's notice. That is the most likely place for this summary to break.
What the deposit and the 20-share lot actually block
The two levers aim at different things. The deposit is an eligibility gate — new buying only opens if the cash is there — so it filters entry itself. The lot-size rule instead enlarges the size of a single order for someone already inside, which reads as an attempt to curb rapid small-ticket churn.
How much a 20-share lot actually costs depends heavily on the share price. Leveraged ETPs trade anywhere from a few thousand won to tens of thousands, so the same twenty shares bite very differently. The table below converts assumed share prices into a minimum order size.
| Assumed share price (won) | Minimum order, 1-share lot (won) | Minimum order, 20-share lot (won) | Orders possible with 30M won |
|---|---|---|---|
| 2,000 | 2,000 | 40,000 | 750 |
| 5,000 | 5,000 | 100,000 | 300 |
| 10,000 | 10,000 | 200,000 | 150 |
| 30,000 | 30,000 | 600,000 | 50 |
The point is that the lot rule's bite is inversely proportional to price. A 2,000-won product bundled into twenty shares still costs only 40,000 won, effectively no constraint; a 30,000-won product turns one order into 600,000 won and breaks a scaling-in approach outright. The same regulation lands unevenly across products.
How much worse than the underlying did July get?
The timing traces back to the size of the losses. Figures compiled by Herald Business for July 1–14 show an average return of -42.1% for leveraged ETFs tracking Samsung Electronics and -53.5% for those tracking SK Hynix. Over the same window the underlying stocks returned -21.26% and -27.81%.
A 2x product did not fall exactly twice as far — the direction and size of that gap is daily rebalancing showing its face.
Placing a naive doubling of the underlying return next to the actual figure makes the gap visible. The table below works that conversion directly from the two reported numbers.
| Product (July 1–14) | Underlying return (%) | Naive 2x conversion (%) | Actual leveraged return (%) | Gap (pp) |
|---|---|---|---|---|
| Samsung Electronics leveraged ETF | -21.26 | -42.52 | -42.10 | +0.42 |
| SK Hynix leveraged ETF | -27.81 | -55.62 | -53.50 | +2.12 |
Both products lost less than the naive doubling. That looks backwards but follows from the structure. A product that targets a daily multiple rebuilds its 2x exposure each day off a shrunken balance, so in a stretch that keeps pushing one direction the exposure shrinks alongside it and the loss undershoots the arithmetic multiple. The larger 2.12pp gap on Hynix simply reflects a deeper fall.
The catch is that this property reverses with direction. In a choppy, range-bound stretch the same mechanism grinds the balance down instead. That asymmetry, worked through with numbers, is the subject of how negative compounding turns long holding periods into losses. July's figures are closer to one extreme end of that structure than a counterexample to it.
Why rebalancing piles up right before the close
Alongside deposits and training, spreading out rebalancing times came up in the policy discussion. Herald Business reported daily rebalancing volumes swinging between 700 billion and 2.1 trillion won, with the flow concentrated just before the market closes. Matching a daily multiple means adjusting positions against a closing-price benchmark, so the clustering is baked into the product design.
The scale is not marginal either. On July 14, leveraged product turnover reached 18.27 trillion won, or 39% of all ETF turnover. Investor deposits peaked at 139.69 trillion won on June 4 and fell to 105.58 trillion won by July 10 — roughly 34 trillion won drained in a little over a month.
What those figures say is that leveraged products are no longer a side show. When trillions of won of mechanical orders land on a specific stock near the close, the formation of that closing price is itself affected, quite apart from the product's own return. It is another reason to look at where tracking error and price divergence open up in any individual product.
What to watch from here
- How your holdings are classified — single-stock or index-based, confirmed against the product-code list in your brokerage's notice. The reach of this increase turns on that line
- How the deposit is assessed — the 30 million won is on a cash basis. Whether substitute securities count, and whether existing holdings are excluded from the calculation, varies by brokerage notice
- Your training record — with the course moving to three hours, whether anyone who completed the two-hour version has to retake it
- The November lot change — once 20-share lots apply, use the conversion table above to work out the minimum order size for the products you actually trade
- Daily rebalancing volume and turnover share — the 0.7–2.1 trillion won band and the 39% share of ETF turnover, and where both move after the rules bite
- Investor deposit balances — whether the 105 trillion won level rebounds or keeps sliding is the first read on whether the higher bar is working
