Global banks are buying insurance against something that has never happened: Samsung Electronics or SK Hynix losing half their value in a single day. The price of that insurance has doubled in two months, according to a Bloomberg-sourced report. What they’re paying for is protection against gap risk — the danger that a stock’s price jumps straight past the level where you meant to sell, with nothing in between.
Normally, if a stock starts falling, you can sell as it drops — 5%, then 8%, then 10% — and cut your losses along the way. Gap risk is what happens when that ladder disappears. A trading halt, a limit-down close, or a crash that outruns every stop-loss order can all cause it.
The reason banks specifically need this protection traces back to how leveraged ETFs work. A 2x or 3x single-stock ETF doesn’t buy twice the shares — it enters a total return swap with a bank, a contract where the bank pays the ETF the multiplied return without either side owning the stock outright. That’s fine in normal markets. But if the stock falls more than 50% in a day (33% for a 3x fund), the ETF’s losses exceed its entire asset base, and the bank on the other side of the swap can be left holding the difference.
That’s exactly what happened to Lucid Group’s 2x leveraged ETF, ticker LCDL, on July 14, 2026. Lucid stock plunged as much as 57% intraday on bankruptcy speculation. The swap counterparty terminated the position, and the fund’s net asset value went negative before the stock even finished the day. GraniteShares delisted it immediately — investors got nothing back.
Banks are now paying up to hedge the same scenario on Samsung and SK Hynix, whose leveraged-ETF exposure has ballooned since their single-stock products launched. A BNP Paribas pitch from May priced a crash put on SK Hynix — paying out only if the stock craters more than 50% within six months — at up to 6.5% annually, up from 3.5% in March. Goldman Sachs went further, pitching investors yields of 14.2% to 20% just to take the other side of that bet.
None of this means a 50% one-day drop is likely. SK Hynix’s worst single day on record is still a 15.4% closing loss. But gap risk isn’t about likelihood — it’s about what happens on the day nobody priced in.
Not advice. Just how I see it.
