Korea stablecoin outflows sustain 18-month streak

TLDR

South Korean crypto exchanges have seen net stablecoin outflows to foreign platforms for 18 straight months, signaling a persistent shift of local capital offshore.

1. In June 2026, Korean exchanges sent roughly 560 billion won more in stablecoins abroad than they received, marking the 18th consecutive month of net outflows.
2. Evidence suggests Koreans are using stablecoins to access high leverage, derivatives, tokenized real world assets, and DeFi products that are not available on domestic venues.
3. The streak highlights weakening local liquidity and rising regulatory pressure, making future policy choices in Seoul a key driver for Korean crypto markets.

Confidence: high because the figures come from official supervisory data reported this week.

Deep Dive

1. Flow Magnitude And Streak

Financial Supervisory Service data shows that Upbit, Bithumb, Coinone, Korbit, and Gopax recorded about 560.3 billion won (around 367 million dollars) in net stablecoin outflows in June 2026, with 2.7625 trillion won sent abroad and 2.2022 trillion won returning. This marks 18 consecutive months of net outflows since January 2025, with second quarter 2026 outflows totaling 1.6872 trillion won. Domestic crypto trading volume across these exchanges fell about 54.6 percent year over year in the first half of 2026, underscoring a shrinking onshore market and sustained use of offshore platforms for crypto activity, as reported in South Korean stablecoin outflows hit 18 months.

2. Why Capital Is Moving

Regulator sourced commentary and local media suggest these stablecoin transfers are mainly used to access products Korean exchanges do not list, including overseas crypto derivatives, tokenized real world assets, DeFi, staking, and leveraged products tied to major Korean stocks such as Samsung Electronics and SK Hynix. A separate analysis notes that June stablecoin net outflows were equal to about 77.6 percent of Koreans net overseas stock purchases, pointing to a broader pattern of capital seeking risk and yield abroad rather than onshore, according to Yahoo Finance coverage. At the same time, Korea has confirmed a 22 percent tax on larger crypto gains from 2027, which may be dampening local speculative activity and pushing sophisticated users toward foreign venues.

3. Market And Policy Risks

Persistent net outflows weaken order book depth and fee revenue on Korean exchanges, increasing reliance on foreign platforms that may be less aligned with Korean investor protection standards. Lawmaker Lee Jong wook has warned that Koreans are being left effectively defenseless against high risk derivatives on foreign exchanges and called for faster safeguards and a comprehensive Digital Asset Basic Act. Regulators are considering stricter controls on exchanges and potential frameworks for won backed stablecoins and domestic product expansion, but details are unsettled, so the next data prints will show whether outflows extend to 19 months and whether policy shifts can redirect flows back onshore.

Conclusion

Koreas stablecoin outflows are not a one month anomaly but a long running pattern of capital leaving domestic venues to chase leverage and yield abroad. For crypto users, the key drivers are product gaps, tax and regulatory expectations, and the relative appeal of offshore platforms. The next phase of Korean policy, especially around derivatives access, stablecoin rules, and the Digital Asset Basic Act, will determine whether this offshore streak slows or becomes a structural feature of the regions crypto market.
