Seoul curbed leveraged ETFs. Retail bought 3.5 trillion won of chip-linked ELS instead.

Start with the paper itself. Meritz Securities is offering 43.4% a year on Samsung Electronics and SK hynix, with principal lost if either name falls 70% during the term and then closes well below its reference price at maturity ^[5]. Both stocks remain more than 22% below the records they set in June ^[9], so a reference struck near current levels puts that trigger roughly 77% below the June peak ^[1]. Distance like that is what makes a 43.4% coupon printable, and it is also what makes the product read as a yield instrument rather than as a sold option.

The load-bearing word in the terms is "either" ^[5]. A basket of two memory names does not halve the risk; it gives the position two ways to break, and both underlyings are geared to the same high-bandwidth memory demand that is funding the issuers' largest-ever shareholder returns ^[10]. Kiwoom's version pairs SK hynix with LG Electronics and tells buyers that missing the payment conditions means a loss of 30% to 100% ^[6]. Upside capped at the coupon, downside open to the whole principal.

What the Financial Supervisory Service adds next month is a notification when a product nears its knock-in level, plus a duty to review products when market conditions sharply raise risk ^[13]. Both are answers to the 2024 Hong Kong H-index episode, where the FSS found some large brokerages had failed to properly disclose the risks of China-linked structured products ^[12]. They are decent answers to that particular finding. But accounts with confirmed losses on those products held 10.4 trillion won of principal and lost 4.6 trillion won ^[11], about 44 won in every 100 ^[2]. The damage was severity, not surprise, and a message sent near the barrier does not change severity.

Nothing in the new regime touches coupon level or barrier depth, and nothing addresses how much of a month's issuance points at the same two tickers ^[13][2]. The bull case for the underlyings is real and beside the point: improving finances and record payouts are earnings events ^[10], while the ELS only asks whether the weaker of two correlated stocks stays above a line. Maxence Vissault, chief investment officer at Arkévium Capital, described the mechanism as issuance rising after a correction or volatility shock, when entry prices look attractive and coupons climb, with the risk being confusion between good companies and safe entry prices ^[8]. Analysts telling Korean clients the sell-off has created a favourable entry point for ELS are supplying the first half of that sentence ^[7].
