Net stablecoin outflows from South Korea's five major cryptocurrency exchanges reached $10.4 billion (approximately ₩14.92 trillion) between January 2025 and June 2026, a figure that now rivals the country's total overseas stock investment over the same period, according to data from the Financial Supervisory Service (FSS).

South Korea ranks among the largest retail cryptocurrency markets in Asia, making the scale of these outflows particularly significant for both domestic financial stability and the broader global stablecoin ecosystem. The FSS, the country's top financial regulator, compiled the data covering activity across Upbit, Bithumb, Coinone, Korbit, and Gopax — the five platforms that dominate domestic crypto trading. The data reveals a consistent pattern: Korean won is converted into dollar-pegged stablecoins and subsequently moved to offshore platforms.

Drivers of Capital Outflow

South Korean retail investors are seeking access to higher leverage and financial products that domestic exchanges either do not offer or are not permitted to provide under local regulations. Stablecoins such as USDT and USDC serve as the bridge: investors convert won to these dollar-denominated tokens, transfer them to offshore platforms, and gain access to a significantly broader range of trading instruments. This pattern mirrors a broader global trend in which dollar-pegged stablecoins, collectively representing over $200 billion in market capitalization, have become the de facto settlement rail for cross-border crypto activity.

In June 2026 alone, stablecoin outflows totaled ₩560.3 billion (approximately $390 million), representing 77.6% of the net overseas stock purchases made by domestic investors during the same month. In Q2 2026, stablecoin outflows climbed to ₩1.69 trillion, slightly surpassing the ₩1.62 trillion in net overseas stock selling recorded in the same quarter.

Declining Domestic Market Activity

The outflows coincide with a sharp contraction in domestic exchange activity. The active user ratio across the five major exchanges fell from 35.7% at the end of January 2025 to 19.5% by the end of June 2026. Since peak trading activity in March 2026, more than 400,000 KYC-verified users have ceased trading entirely. Total virtual assets held by domestic investors have declined by 54.7% over the same period.

Lawmakers Call for Won-Pegged Stablecoin

National Assembly members Lee Jong-wook and Min Byeong-deok have raised concerns about capital flight and advocated for the development of a won-pegged stablecoin. Their argument centers on the premise that a domestic stablecoin denomination, combined with competitive financial products built on top of it, would reduce the incentive for investors to move assets offshore. The proposal places South Korea alongside several jurisdictions — including the European Union, which has advanced its own digital asset framework under MiCA, and the United States, where stablecoin legislation has been under congressional consideration — in grappling with how to keep cryptocurrency activity within a regulated domestic perimeter.

Under the current landscape, the domestic market offers the Korean won but lacks the range of products available on offshore platforms, which require dollar-denominated stablecoins for access.

Broader Regulatory Context

The decline in active user ratio from 35.7% to 19.5% represents a structural shift affecting exchange economics, market depth, and the overall appeal of the domestic crypto market to new participants.

South Korea has historically responded swiftly to perceived systemic risks in cryptocurrency markets. The country implemented real-name account requirements for exchanges in January 2018, well ahead of most Western regulators, and enacted its Virtual Asset User Protection Act in July 2023 to establish investor protection and market integrity safeguards.
