Korea stablecoin outflows drive offshore shift

TLDR

South Korea has seen persistent net stablecoin outflows as local traders move funds from domestic exchanges to offshore platforms offering products they cannot access at home.

1. South Korean exchanges have recorded about $10.8 billion in net stablecoin outflows over 18 months, with June alone seeing roughly $367 million sent offshore.
2. These flows are driven mainly by product gaps, as local platforms cannot legally offer high leverage derivatives, DeFi, staking, or many tokenized real world assets that offshore venues provide.
3. Regulators are debating tighter rules on cross-border crypto activity and stablecoins, so the offshore tilt is likely to remain in focus until domestic rules and offerings catch up.

Deep Dive

1. Size And Persistence Of The Outflows

Data from South Koreas Financial Supervisory Service shows that in June 2026, the five major won-based exchanges (Upbit, Bithumb, Coinone, Korbit, Gopax) sent about 2.7 trillion won in stablecoins offshore and received 2.2 trillion won back, leaving net outflows of 560.3 billion won, around $367 million in one month. That marked the 18th consecutive month of net stablecoin outflows.

Over January 2025 to June 2026, cumulative net outflows reached around 14.9 trillion won, roughly $10.8 billion, according to figures cited by lawmaker Lee Jong wook. Upbit accounted for the majority, followed by Bithumb and Coinone.

In June, net stablecoin outflows were roughly three quarters as large as Korean investors net overseas stock purchases, and in Q2 they actually surpassed net foreign stock sales, highlighting that stablecoins have become a primary channel for sending risk capital abroad.

2. Why Traders Are Shifting Offshore

Reports from local media and analysts attribute the outflows primarily to regulatory constraints at home rather than classic capital flight. Domestic exchanges operate under the Specific Financial Information Act and related rules that prevent them from offering many high demand products, including:

1. High leverage futures and perpetual derivatives on crypto and tokenized stocks.
2. Decentralized finance pools, liquid staking, and many yield-bearing stablecoin or RWA structures.
3. A broad range of tokenized real world assets and structured products.

By contrast, offshore platforms such as Binance and Bybit can list contracts tied to Korean equities, expansive crypto derivatives, and global RWA protocols, so Korean traders use stablecoins to bridge into those markets. Authorities have flagged this as regulatory arbitrage, not direct breach of capital controls.

3. Regulatory Response And Risks To Watch

South Korea is working on a Digital Asset Basic Act that would be its first full framework for crypto and stablecoins, alongside interim proposals for licensing and phased stablecoin rules. Supervisors are also considering extending Travel Rule reporting to smaller transfers and stepping up action against unregistered foreign exchanges serving Koreans.

Lawmakers worry that persistent outflows into offshore ultra high leverage products and opaque DeFi venues increase investor protection and systemic risk concerns. At the same time, if domestic rules remain restrictive and product innovation lags, the incentive to keep using stablecoins to move capital abroad will stay strong.

Conclusion

South Koreas steady stablecoin outflows reflect a structural mismatch between domestic regulation and the global crypto product set, with traders using stablecoins to access offshore leverage, yield, and RWA exposure. Until local rules and offerings narrow that gap, stablecoins are likely to remain a primary conduit for Korean risk capital leaving the country, and policy decisions on stablecoins and cross-border supervision will be important signals for both domestic exchanges and global platforms serving Korean users.
