South Korea's five largest won-based crypto exchanges — Upbit, Bithumb, Coinone, Korbit and Gopax — sent a net 560.3 billion won, or roughly $367 million, in stablecoins to overseas venues in June alone, according to data from the Financial Supervisory Service. Gross outbound transfers reached 2.76 trillion won against 2.20 trillion won flowing back into domestic platforms, extending an uninterrupted streak of net stablecoin outflows that has now run for 18 consecutive months since January 2025.
In response, regulators have moved to tighten the perimeter. Exchanges must now request user information — names, transfer reasons and the origin of funds — on transfers, with transfers exceeding 10 million won (roughly $7,000) to overseas destinations or self-hosted wallets facing enhanced monitoring. Google Play Store access has already been pulled for Bybit, MEXC and HTX, part of a broader restriction covering at least 29 unregistered derivative platforms.
Why the Money Keeps Leaving
The outflows are not being driven by panic or a loss of confidence in domestic platforms. South Korea's five licensed exchanges operate under the Specific Financial Information Act, which enforces strict anti-money-laundering controls and effectively locks users out of high-leverage derivatives, DeFi pools, liquid staking and most real-world-asset protocols. Traders who want access to those products have little choice but to move stablecoins to offshore venues where they are legally available, which is why the pattern has persisted for a year and a half rather than spiking around any single event.
A Regulator Under Pressure
The scale of the migration is starting to draw political attention. On August 2, People Power Party lawmaker Lee Jong-wook said the government must comprehensively examine its investor-protection and supervisory frameworks and move swiftly to improve regulations. The Financial Services Commission has itself flagged cross-border stablecoin activity as a source of foreign-exchange and money-laundering risk, and has called for international cooperation to prevent regulatory arbitrage between jurisdictions with different stablecoin frameworks — the same dynamic now playing out inside Korea's own borders.
A Framework Still in Progress
The FSC's longer-term answer is a unified Digital Asset Framework Act, now before the National Assembly's Political Affairs Committee, meant to set formal stablecoin rules and strengthen investor protection before the end of 2026. Until that legislation is finalized, though, the app-store restrictions and enhanced transfer monitoring are the tools regulators have to work with, and officials have said they will watch whether net outflows and large transfers actually decline once the new measures take effect — the clearest sign yet that, so far, tighter monitoring has not been enough to reverse the trend.
