Korea's crypto exchange market cap falls 33% as Bitcoin drops, amid continuing offshore exodus
Korea's licensed crypto exchanges lost 78% of operating income and a third of their combined market capitalization in H1 2026, a regulator survey shows. Bitcoin fell by the same third over the half, so the case for an exodus to offshore leverage has to rest on won deposits and turnover, figures that fit a move into Korean stocks just as well.
The Investor · Invest desk
What happened
- Won-denominated deposits fell 35% in the half, to 5.2 trillion won from 8.1 trillion, even as the number of accounts eligible to trade rose 0.4%.
- Binance listed a perpetual on KORU, a US fund returning three times the Kospi's daily move, at 20x on June 22 and raised it to 50x four days later, for exposure up to 150 times the index.
- Tiger Research and Chainalysis estimate Korea-linked crypto outflows of about $120 billion in 2025 and project about $52 billion for 2026.
- Combined daily volume at Upbit, Bithumb, Coinone, Korbit and Gopax fell about 89% year on year by Cointelegraph's July count, while the Kospi more than doubled in 12 months.
Why it matters
- What doesn't add up contradiction Cryptopolitan and Cointelegraph read the same KoFIU survey as evidence of different exits, so it does not yet show that the leverage rules are what cost exchanges their deposits.
- What it limits constraint With spot as the only product they can sell, licensed exchanges have nothing to offer a trader who wants leverage on a rising Kospi, so a domestic stock rally drains their volume.
- Who's exposed exposure The exit runs through licensed exchanges, where won buys Tether before it moves abroad, so those venues are the point where Korean rules can still reach the offshore trade.

Korea drafts tokenized-securities rules for 2027 as bills seek a fourth crypto-tax delayConfirmed3 publishers
The combined market capitalization across the 26 surveyed firms [2] went from 87.2 trillion won to 58.9 trillion [3], a fall of 28.3 trillion won, or 32.5% [24]. Bitcoin fell 33%, to $58,559, by the end of June [7]. A portfolio that moved with Bitcoin and never traded would have lost about the same share. The regulator tied much of the loss to Bitcoin [7].
Won deposits are cash, so their 35% fall [4] measures money that moved, whatever Bitcoin did. Daily turnover fell to 3.1 trillion won from 5.4 trillion [5]. Operating income fell 293.2 billion won, to 81.6 billion [9], on sales down 41% [8]. The two percentages may not share a base: Cryptopolitan describes the profit comparison as against a year earlier [1], while KoFIU measured volume against the previous six months [6].
That money went offshore, into Korean stocks, or both. Cryptopolitan attributes the deposit decline to overseas platforms offering products Korea does not allow [29]. Cointelegraph's figures point at the stock market: crypto held by Korean investors fell 50.2% to 60.6 trillion won in roughly a year to May, a drop ChosunBiz linked to money moving into stocks [20]. The third reading is that much of the offshore trade is itself a leveraged bet on Korean stocks. Contracts on SK Hynix, Samsung Electronics and crude oil were among the most-traded by Korean wallets on Hyperliquid, where about 1,200 of them traded $4.97 billion of notional volume in July [17]. Even the KORU contracts are Kospi exposure [11].
For the first half, the timing favours stocks. Binance's 20x contracts on Samsung Electronics, SK hynix and Hyundai Motor came in June [12], and its KORU contract was live for only the last nine days of a 181-day half [25]. Neither report breaks the survey down by month. Tiger Research and Chainalysis project 2026 outflows at 43% of last year's pace [26]. Their estimate that about 700 trillion won left domestic exchanges between 2021 and 2026 [15] is a five-year sum of transfers, about 12 times the end-June domestic market capitalization [27].
I think the Kospi took more of the first half's money than Binance did. The counter-thesis is that the two are one trade, and that Korean traders would have kept their won at home if a licensed exchange could sell them leverage. Shinhan Securities analyst Park Sung-jae said in July that investors were leaving for the futures and leverage that foreign exchanges offer [18]. Spot trading, he said, is "the only de facto trading option" in South Korea [19]. Domestic crypto trading had by then fallen to about 1.6% of Kospi turnover [18]. If the second-half survey shows won deposits still falling after Bitcoin recovers, the offshore account is the better one.
Traders who did leave carry their losses outside Korea's investor protections [14]. On Binance's 20x KORU contract, a 5% fall in the fund erased a long position's margin [28]. On June 23 the Kospi fell 9.99% and KORU fell 35.7%, to $700.01, in one session [13]. The regulator's own warning in the survey was about tokens at home: 93 of the 234 listed on only one exchange were appraised at 100 million won or less [22].
What to watch
- Whether Binance holds KORU at 50x, and whether Bybit, OKX and KuCoin follow, after a June 23 session that moved about seven times the distance needed to erase a 20x long.
- Tiger Research and Chainalysis's full-year 2026 count: outflows well above the projected $52 billion would favour the offshore account over the stock-rotation one.
- The National Assembly review, forced by a 50,000-signature petition, of the 22% tax on crypto gains above 2.5 million won due from January 2027, and whether either party's proposed delay passes.
