South Korea is currently facing significant challenges with stablecoins, a situation that has garnered the attention of regulators and investors alike. Over the span of 18 months from January 2025 to June 2026, the net outflows of stablecoins from the country’s five major cryptocurrency exchanges totaled an astounding $10.4 billion, approximately ₩14.92 trillion. This figure is now comparable to the nation’s entire overseas stock investment within the same timeframe, highlighting the urgency of the issue for policymakers.
The data provided by South Korea's Financial Supervisory Service tracks the activities of prominent exchanges, including Upbit, Bithumb, Coinone, Korbit, and Gopax. The consistent pattern observed shows that investors are converting Korean won into dollar-pegged stablecoins before transferring them to offshore platforms.
Why are investors moving their money?
Investors in South Korea are seeking access to higher leverage and financial offerings that are largely unavailable on domestic exchanges due to regulatory restrictions. By converting their won into stablecoins like USDT or USDC and transferring them offshore, these investors gain access to a broader range of financial products that appeal to their risk appetite.
In June 2026 alone, the outflow of stablecoins reached ₩560.3 billion, which translates to approximately $390 million in one month. This amount represented 77.6% of the total net overseas stock purchases made by South Korean investors during the same timeframe. Furthermore, during the second quarter of 2026, stablecoin outflows totaled ₩1.69 trillion, slightly surpassing the ₩1.62 trillion net selling of overseas stocks, illustrating the shift in investor behavior.
The domestic exchange landscape is feeling these changes acutely. Data indicates that the active user ratio across the five major exchanges has dwindled from 35.7% at the end of January 2025 to a mere 19.5% by the conclusion of June 2026. This translates to more than 400,000 verified users who have ceased trading since the peak activity noted in March 2026. Additionally, total virtual assets held by domestic investors have plummeted by 54.7% in the same period.
In response to the capital flight concerns, lawmakers such as Lee Jong-wook and Min Byeong-deok have suggested the creation of a won-pegged stablecoin as a means to mitigate this issue. The rationale is straightforward: if Korean investors had access to a domestic stablecoin denominated in won, paired with competitive financial products, the desire to transfer assets offshore would likely decrease. Currently, while the domestic market offers the won, the absence of attractive financial products pushes users toward offshore options that necessitate dollar-denominated stablecoins.
What does this trend mean for investors?
Observing the decline in active users is critical for anyone monitoring the Korean crypto market. The drop from 35.7% to 19.5% is not just a minor fluctuation; it signals a structural change with profound implications for exchange economics, market depth, and the attractiveness of the domestic market to new participants.
Historically, South Korea has been proactive in regulating the crypto landscape whenever there is a perceived systemic risk. The implementation of real-name account requirements for exchanges was introduced well ahead of many Western counterparts, and South Korea passed the Virtual Asset User Protection Act with remarkable swiftness. As the situation evolves, it remains to be seen if further regulatory actions will be taken to counteract these challenges.
