South Korean crypto exchanges sent a net 560.3 billion won, roughly $367 million, in stablecoins to overseas platforms in June 2026, extending an uninterrupted streak of monthly net outflows to 18 months. The figures come from Financial Supervisory Service data submitted to People Power Party lawmaker Lee Jong-wook and reported by Yonhap News Agency on August 2.
The country's five major won-based exchanges, Upbit, Bithumb, Coinone, Korbit and Gopax, transferred about 2.76 trillion won offshore during the month while receiving roughly 2.20 trillion won back. Cumulative net outflows since the data series began in January 2025 now total approximately 14.92 trillion won, or about $10.4 billion.
The driver is not speculation but access. Korean traders are moving dollar stablecoins abroad to reach overseas derivatives, tokenized real-world assets, decentralized finance, and staking products that domestic platforms cannot legally offer.
Stablecoin net outflows reached 77.6% of the value of Korean investors' net overseas stock purchases in June, up from roughly 20% in early 2025.
Key Takeaways
- June net outflows hit 560.3 billion won, about $367 million, the 18th consecutive monthly net outflow.
- Cumulative outflows since January 2025 reach roughly $10.4 billion across the five major Korean exchanges.
- Regulatory restrictions drive the flows, as DeFi, staking, RWAs, and leveraged derivatives remain unavailable domestically.
- Stablecoins now rival overseas equities as a capital-flight channel, at 77.6% of net foreign stock purchases in June.
- Lawmakers are citing the data to push for a won-pegged stablecoin framework and corporate market access.
What the Data Shows
The June figure marks an increase from May's 477.1 billion won but remains below January's 1.14 trillion won peak. Across the second quarter as a whole, net stablecoin outflows reached 1.69 trillion won, or roughly $1.1 billion.
The comparison that alarmed lawmakers involves overseas equities. Korean retail investors have long moved capital abroad through foreign stock purchases, and in June the Korea Securities Depository recorded net foreign stock buying of about $472 million, meaning stablecoin outflows equalled 77.6% of that figure.
That ratio has climbed sharply. In early 2025 stablecoin net outflows sat near 20% of net overseas stock purchases, so the channel has moved from marginal to nearly equivalent in about eighteen months.
The second quarter produced an even starker signal. Korean investors were net sellers of overseas stocks to the tune of 1.62 trillion won during the period, while stablecoin outflows continued at 1.69 trillion won, meaning capital left through the stablecoin channel even as it returned through the equity channel.
Why the Money Is Leaving
Market participants cited by Yonhap attribute the transfers to demand for products restricted or unavailable on domestic exchanges. Korea's Specific Financial Information Act creates a licensing perimeter that keeps decentralized finance, liquid staking, tokenized real-world assets, and leveraged derivatives off local platforms.
The mechanism is straightforward. A Korean trader who wants exposure to a perpetual futures market or an onchain yield strategy converts won into a dollar stablecoin at a domestic exchange, sends it to an offshore venue, and trades there.
The domestic consequence is thinning engagement. Active user ratios across the five major exchanges have fallen to roughly 19.5%, and each outbound transfer removes liquidity from licensed Korean venues while adding it to platforms outside the regulator's reach.
The pattern has persisted through very different market conditions. Eighteen consecutive months spans both rising and falling crypto prices, which suggests a structural response to product availability rather than a cyclical reaction to sentiment.
Why This Matters for Stablecoins
The data is one of the clearest national-level measurements of dollar stablecoins functioning as a cross-border capital conduit. Every won converted into USDT or USDC and sent offshore is a small act of dollarization, executed by retail traders rather than institutions.
That dynamic is precisely what non-US regulators have been warning about, and it explains the urgency behind Korea's won stablecoin push. Lawmakers are now citing these outflow figures to argue for institutionalizing a KRW-pegged stablecoin and opening the corporate market, on the logic that a domestic alternative would keep more of the flow onshore.
The private sector has been moving in parallel. Circle signed memoranda of understanding with Kakao Group and Toss Bank in July, as covered in our Circle Korea partnership analysis, building on April agreements with Upbit and Bithumb that together handle over 95% of Korean daily crypto volume.
There is an uncomfortable tension in that sequence. The same dollar stablecoins driving the outflows are issued by the company Korea's largest platforms are partnering with, which means the infrastructure buildout and the capital-flight problem share a common asset.
The Broader Non-Dollar Question
Korea's situation is a specific instance of a global pattern. Dollar-pegged tokens account for over 99% of stablecoin market capitalization, so any country whose residents adopt stablecoins at scale is effectively adopting dollar exposure, a structural dominance we mapped in our stablecoin infrastructure landscape.
The policy responses are diverging. Japan built its yen stablecoin framework on existing electronic payment instrument rules, Hong Kong wrote a dedicated ordinance and licensed issuers under it, and Korea is still legislating while capital leaves through the channel the legislation is meant to address.
The offshore dimension complicates enforcement further. USDT retains dominant share in unregulated retail markets even as it faces exclusion from regulated venues in the EU, a two-tier structure we detailed in our USDT Q2 market report, and Korean outflows feed exactly that offshore tier.
Whether a won stablecoin would reverse the trend is genuinely uncertain. The outflows are driven by product access rather than currency preference, so a KRW token that still cannot reach DeFi or derivatives may address the denomination without addressing the demand.
Conclusion
Eighteen months and $10.4 billion is no longer a crypto market curiosity. It is a measurable, sustained channel through which retail capital exits a major economy, and Korean regulators now have their own data documenting it.
The finding cuts against a common assumption about stablecoin adoption. These flows are not payments, remittances, or commerce; they are access-seeking behavior generated by the gap between what domestic rules permit and what global markets offer.
The policy question that follows is harder than issuing a token. Korea can institutionalize a won stablecoin, but unless the product restrictions that push traders offshore change alongside it, the currency of the outflow may shift while the outflow itself continues.
FAQ:
1. How much did South Korea's stablecoin outflows total in June 2026?
Net stablecoin outflows from South Korea's five major exchanges reached 560.3 billion won, approximately $367 million, in June 2026. The exchanges sent about 2.76 trillion won in stablecoins to overseas platforms and received roughly 2.20 trillion won back, according to Financial Supervisory Service data reported by Yonhap News Agency.
2. Why are stablecoins flowing out of South Korea?
Korean traders move dollar stablecoins offshore to access products unavailable on domestic exchanges, including overseas derivatives, tokenized real-world assets, decentralized finance, and staking services. Korea's Specific Financial Information Act creates a licensing perimeter that keeps these products off local platforms, so users convert won to stablecoins and trade at foreign venues instead.
3. How long has the outflow streak lasted?
June 2026 marked the 18th consecutive month of net stablecoin outflows, a streak that began in January 2025 when the data series started. Cumulative net outflows over that period total approximately 14.92 trillion won, or about $10.4 billion, across Upbit, Bithumb, Coinone, Korbit and Gopax.
4. How do stablecoin outflows compare to overseas stock purchases?
In June 2026, stablecoin net outflows equalled 77.6% of the value of Korean investors' net overseas stock purchases, up from roughly 20% in early 2025. During the second quarter, Korean investors were net sellers of foreign stocks while stablecoin outflows continued, meaning capital left through the stablecoin channel even as it returned through equities.
5. Will a Korean won stablecoin stop the outflows?
It is uncertain. Lawmakers are citing the outflow data to push for institutionalizing a won-pegged stablecoin and opening the corporate market, but the transfers are driven by access to restricted products rather than currency preference. A KRW stablecoin that still cannot reach DeFi, staking, or leveraged derivatives would change the denomination of the flow without removing the underlying demand.
