Key insights
- South Korean capital is deemed to flow to overseas exchanges via derivatives, DeFi, staking and tokenized real-world assets that are not available in South Korea.
- The 18-month continuous outflow period underlines a regulatory shortfall as investors are looking for products other than licensed exchanges.
- The phenomenon of a stablecoin that cannot be stopped may indicate a fundamental trend and a shift of crypto activity beyond the borders of certain countries.
South Korean net stablecoin outflows reached 560.3 billion won (about $367 million) in June 2026, continuing an uninterrupted string of capital flowing from local crypto exchanges to foreign ones for 18 consecutive months. The new numbers underscore the rising demand for digital asset products which are still not offered in the country’s regulated crypto marketplace.
The Financial Supervisory Service reported that the five biggest exchanges that offer trading in won during the month accepted 2.2022 trillion won in the form of stablecoins from foreign exchanges, while 2.7625 trillion won were sent to them. The ongoing disparity has sparked worries regarding investor safeguards, capital inflows, and the growing trend of crypto trading shifting to overseas exchanges, particularly within Korea.
June Transfers Extend an 18-Month Streak
The five exchanges transferred 2.7625 trillion won in stablecoins to foreign platforms during June. Meanwhile, overseas exchanges returned 2.2022 trillion won to those Korean venues.
The difference produced June’s 560.3 billion won net outflow. That total rose from 477.1 billion won in May.
South Korean Stablecoins Post 18 Straight Months of Net Outflows to Overseas Exchanges

However, June remained below January 2025’s 1.1429 trillion won peak. The available data series began that month, and every period has shown net outflows.
Second-quarter transfers also showed sustained demand for offshore access. Net stablecoin outflows reached 1.6872 trillion won between April and June.
The figures indicate persistent capital movement, although they do not reveal every investor’s final destination. Transfers through private wallets may also fall outside the exchange-based dataset.

Offshore Products Pull Crypto Capital Abroad
Market observers link the transfers mainly to services unavailable on Korean exchanges. Those products include crypto derivatives, tokenized real-world assets, decentralized finance and staking opportunities.
Some offshore venues also list leveraged contracts linked to major Korean companies. Examples include Samsung Electronics, SK Hynix and Hyundai Motor. Yet the FSS data only tracks exchange-to-exchange movements. It cannot confirm how traders used every transferred stablecoin after arrival.
Therefore, derivatives demand remains a plausible explanation rather than a verified transaction-level conclusion. Stablecoins may also support custody, payments or portfolio rebalancing. Local platforms are more regulated in country and largely focused on spot trading. By contrast, offshore exchanges offer broader instruments and higher leverage.
That difference may encourage sophisticated traders to move capital abroad. It also places those users beyond many domestic investor safeguards.
Stock Comparisons Raise Policy Concerns
June’s stablecoin outflow equaled 77.6% of Korean investors’ net overseas stock purchases. Those stock purchases reached about 722 billion won during the month. Still, the comparison does not prove both flows involved identical investors. It instead shows stablecoin transfers approaching established cross-border investment channels.
During the second quarter, Korean retail investors recorded 1.6185 trillion won in net overseas stock sales. Stablecoin outflows still reached 1.6872 trillion won during the same period. Meanwhile, trading volume across the five won-based exchanges reportedly fell 54.6% year over year. The decline covered the first half of 2026.
South Korea now faces a difficult regulatory balance. Authorities want stronger investor protection without pushing more activity toward foreign platforms.
Lee urged the government to reassess supervision and close gaps involving offshore derivatives and foreign-exchange management. His concern centers on investors accessing high-risk products without effective domestic remedies.
Three Signals Behind the Data
Points stand out from the 18-month pattern
- The outflows remain consistent despite large monthly changes.
- Offshore product variety appears stronger than domestic availability.
- Exchange data shows direction, but not each investor’s final purpose.
The market structure within South Korea has also shifted. Coinone led June’s average daily stablecoin volume with a 34.8% share.
Bithumb followed with 31.1%, while Upbit held 30.1%. Korbit and Gopax accounted for only small portions.
Coinone’s rise came after it launched its zero-fee USDC trading policy in October 2025. The policy helped it challenge larger competitors in stablecoin activity.
Conclusion
South Korea’s June figures show stablecoins increasingly serving as gateways to global crypto markets. The transfers also expose limits within the country’s controlled domestic trading environment.
However, policymakers cannot assume every overseas transfer funds speculative leverage. Better reporting could separate derivatives activity from DeFi, staking and ordinary treasury movements.
The country must now choose between broader domestic access and tighter controls around offshore flows. Either approach will shape whether the outflow streak reaches a nineteenth month.
