South Korea’s Stablecoin Exodus: What Broke the 18-Month Crypto Deposit Streak

South Korea’s five largest crypto exchanges recorded a net stablecoin outflow of $367 million in June 2026, continuing an 18-month trend largely driven by limited access to certain digital asset products within the domestic market.

According to data from the Financial Supervisory Service (FSS), South Korea’s biggest won-based exchanges — 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 return. The resulting net outflow totaled 560.3 billion won, or roughly $367 million.

The latest figures extend a continuous streak of monthly net stablecoin outflows that began in January 2025 and has now lasted 18 straight months. The trend does not necessarily indicate investors are abandoning crypto markets; instead, it highlights a deeper issue involving limited domestic access to certain trading products and services.

South Korean investors appear to be moving stablecoins offshore not because of widespread market fear, but because local regulations restrict access to many products available on international platforms.

The data comes as the global cryptocurrency market capitalization stands at approximately $2.22 trillion, down 1.1% over the past 24 hours. Total daily crypto trading volume is around $16.9 billion.

The Regulatory Divide Behind South Korea’s Stablecoin Outflows

South Korea’s major domestic exchanges operate under the Specific Financial Information Act, which imposes strict anti-money-laundering requirements and limits access to products such as leveraged derivatives, decentralized finance (DeFi) platforms, liquid staking services, and many real-world asset (RWA) offerings.

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

During the second quarter of 2026, South Korean investors recorded approximately 1.69 trillion won in net stablecoin outflows, compared with 1.62 trillion won in net foreign stock purchases. This suggests stablecoins have increasingly become a channel for investors seeking exposure to global risk assets.

FSS data indicates that several popular crypto investment categories remain unavailable through locally licensed exchanges. Offshore platforms such as Binance and Bybit have attracted Korean traders by offering products linked to major Korean stocks and other international markets, increasing demand for overseas access.

The domestic stablecoin market has also seen significant shifts in exchange competition. Coinone recorded the highest average daily stablecoin trading volume in June at 84.58 billion won, capturing a 34.8% market share after launching zero-fee trading for Circle’s USDC in October 2025.

Bithumb ranked second with 75.57 billion won, representing 31.1% of the market, while Upbit accounted for 73.03 billion won, or 30.1%, according to FSS data cited by Korea Times.

This represents a major change from January 2025, when Upbit controlled 53.5% of the stablecoin market, Bithumb held 42.5%, and Coinone accounted for only 1.8%.

Despite these changes in market share, the overall stablecoin outflow trend has remained unchanged. Coinone’s zero-fee strategy appears to have shifted domestic trading activity between exchanges rather than keeping more capital within South Korea.

Upbit remains the dominant platform in overall crypto trading activity. Data cited by Korea Times from CoinGecko showed that Upbit accounted for about 60% of average daily trading volume in June, while Bithumb represented 32%. However, the stablecoin market is increasingly serving as a bridge for moving capital rather than simply functioning as a trading market.

Regulatory Challenges and Future Outlook

South Korean lawmakers are now calling for updates to the country’s crypto oversight framework. Rep. Lee, cited by Korea Times, urged authorities to strengthen investor protection measures and improve regulatory systems.

Officials have raised concerns that Korean retail investors are accessing highly leveraged products on overseas platforms without the protections offered by domestic regulations. Stablecoin transfers outside traditional oversight channels have also become a growing policy concern.

Discussions have included potential frameworks for won-backed stablecoins, security token offerings, and institutional crypto custody solutions, although no clear legislative timeline has been announced.

The ongoing issue appears to be linked less to capital restrictions and more to the limited range of products available through Korean-licensed platforms. Regulators may need to address multiple areas, including derivatives, DeFi, and staking, to reduce incentives for investors to move funds offshore.

Until domestic exchanges can provide a wider selection of products comparable to global platforms and decentralized networks, stablecoins are likely to continue flowing overseas. June’s figures reinforce a trend that has become firmly established despite broader market movements.
