The End of Korea’s 18-Month Stablecoin Run: Why Traders Are Moving Funds Out

South Korea’s five largest crypto exchanges recorded a combined $367 million in net stablecoin outflows in June 2026, continuing an 18-month trend fueled by limited access to certain digital asset products within the country.

Figures from the Financial Supervisory Service (FSS) show that Upbit, Bithumb, Coinone, Korbit, and Gopax transferred 2.76 trillion won worth of stablecoins to overseas platforms during June, while receiving 2.20 trillion won in deposits. This resulted in a net outflow of 560.3 billion won, equivalent to about $367 million.

The latest monthly outflow extends a streak that began in January 2025 and has continued for 18 consecutive months. The movement does not appear to represent a broad loss of confidence in crypto markets, but rather reflects the gap between domestic offerings and the wider range of services available through foreign platforms.

Korean investors have increasingly moved stablecoins abroad to access products such as derivatives, DeFi applications, and tokenized assets that remain restricted or unavailable on locally regulated exchanges.

The data comes as the overall cryptocurrency market value stands at around $2.22 trillion, down 1.1% in the past 24 hours. Daily trading volume across the crypto sector is approximately $16.9 billion.

Domestic Restrictions Fuel Demand for Offshore Crypto Services

South Korea’s major exchanges operate under the Specific Financial Information Act, which requires strict anti-money-laundering compliance and limits access to several areas of the crypto ecosystem, including leveraged derivatives, decentralized finance protocols, liquid staking, and many real-world asset (RWA) products.

A Korea Times report from Aug. 2 noted that June’s stablecoin outflows represented 77.6% of Korean investors’ net purchases of overseas stocks.

During the second quarter of 2026, net stablecoin transfers leaving South Korea reached roughly 1.69 trillion won, compared with 1.62 trillion won in net foreign stock purchases. The figures suggest stablecoins have become an important channel for retail investors seeking access to global investment opportunities.

FSS data indicates that many popular crypto products cannot be accessed through South Korean-licensed exchanges. Global platforms such as Binance and Bybit have attracted local users by offering products connected to major Korean equities and international markets.

The domestic stablecoin trading landscape has also changed significantly. Coinone recorded the largest average daily stablecoin trading volume in June at 84.58 billion won, accounting for a 34.8% market share after launching zero-fee USDC trading in October 2025.

Bithumb ranked second with 75.57 billion won in average daily volume and a 31.1% share, while Upbit recorded 73.03 billion won and a 30.1% share, according to FSS data cited by Korea Times.

The shift marks a major change from January 2025, when Upbit dominated stablecoin activity with a 53.5% share, followed by Bithumb at 42.5% and Coinone at 1.8%.

Despite the redistribution of stablecoin volume among local exchanges, the broader offshore outflow pattern has continued. Coinone’s zero-fee policy appears to have reshaped domestic trading activity rather than reducing capital movement overseas.

Upbit remains South Korea’s largest crypto platform by overall trading activity, with CoinGecko data cited by Korea Times showing the exchange handled about 60% of average daily crypto volume in June, while Bithumb accounted for 32%.

However, stablecoins are increasingly being used as a bridge for transferring capital to overseas markets rather than simply as assets for domestic trading.

Regulatory Debate Intensifies Over Crypto Access

The continued movement of stablecoins offshore has increased pressure on South Korean policymakers to reconsider the country’s crypto framework. Rep. Lee, according to Korea Times, called for stronger investor protections and improvements to digital asset supervision.

Lawmakers have raised concerns that Korean retail traders are using overseas platforms to access high-leverage products that are not available under domestic rules. They have also pointed to challenges surrounding stablecoin flows outside traditional regulatory channels.

Current discussions include possible frameworks for won-denominated stablecoins, security token offerings, and institutional custody services, though authorities have not announced a specific legislative schedule.

The issue appears to be driven primarily by product limitations rather than restrictions on capital transfers. Expanding access to derivatives, DeFi services, staking, and other crypto sectors may be necessary to reduce the incentive for investors to move funds abroad.

Until South Korean exchanges can provide a broader range of services comparable to international platforms, stablecoins are likely to continue flowing overseas. The June figures indicate that offshore movement has become a persistent feature of the country’s crypto market.
