South Korea's stablecoin outflow continues for 18 months, traders flee local platforms

Numbers went from alarming to commonplace

For a year and a half, the amount of stablecoins flowing out of South Korea's exchanges has exceeded the inflow, and June was no exception. That month, the five major Won-denominated exchanges sent 2.76 trillion won stablecoins to overseas platforms, received 2.20 trillion won, and a net outflow of 560.3 billion won (approximately US$367 million). This continues the trend of continuous net outflows since January 2025.

This continued outflow does not stem from panic, but reflects a structural mismatch between the products available to South Korea's tightly regulated exchanges and the actual needs of traders. Domestic platforms are subject to strict licensing systems and are largely unable to provide tokenized real-world assets, leveraged derivatives, unlicensed DeFi pools and pledge plans-these products have become standard on global exchanges. The result is a slow but continuous outflow of liquidity.

Regulatory gaps driving capital outflows

South Korea's cryptocurrency market is one of the most active retail trading areas in the world, but remains severely restricted. Exchanges such as Upbit, Bithumb, Coinone, Korbit and Gopax are subject to the Specific Financial Information Act, which imposes anti-money laundering obligations and effectively prohibits them from listing tokens that have not been strictly reviewed or providing cross-margin products involving naked short selling. Institutional investors also face stricter custody rules than in many Western jurisdictions.

This created a significant product gap. Traders seeking access to real-world asset agreements, whose chain value has recently exceeded US$20 billion, cannot easily obtain them through local platforms. At the same time, DeFi lending pools, collateralized liquidity derivatives and structured income products-many of which require direct interaction with smart contracts-remain banned in South Korea. The outflow of stablecoins is essentially a capital export tax imposed by the market to circumvent these restrictions.

The 18-month timeline is crucial. The trend began as global interest in on-chain gains rekindled after the bear market in 2022, and accelerated after liquidity pledged tokens and tokenized treasury bonds gained attention. South Korean users-often excluded by domestic crypto premiums-seem willing to transfer assets through third-party wallets and offshore exchanges to obtain services that local liquidity cannot replace.

What traders chase outside?

Analysis points out that there are four main destinations for outflows of stablecoins: crypto and stock derivatives, RWA products, DeFi and pledge services. None of these services are available on a large scale through South Korean-regulated exchanges. The derivatives market is particularly representative: while the Korea Exchange supports some futures products, the offshore market offers deeper leverage, exotic options and cross-collateralized margins, attracting professional and semi-professional traders.

Pledge demand is another driving force. Liquidity pledge or institutional pledge plans on agreements such as Lido-such as those that have recently pushed a token to an 18% increase due to institutional capital inflows-are largely inaccessible to South Korean retail users through compliance channels. It is impossible to pledge assets natively while maintaining liquidity, forcing users to transfer stablecoins overseas, convert them into tokens, and then deploy them directly into smart contracts.

RWA products increase their appeal at the macro level. As tokenized government bond yields attract global capital, some South Korean stablecoin outflows may indicate that users are chasing dollar-denominated gains-gains that are neither taxed nor restricted in the same way domestically. Similarly, the DeFi protocol, which provides complex automated strategies-perpetual options vaults, centralized liquidity positions, cross-chain lending-provides a menu unmatched by domestic exchanges.

The future of domestic exchanges is unclear

For South Korea's local platforms, the impact cannot be ignored. The net outflow for 18 consecutive months has reduced available working capital in the exchange liquidity pool and may widen the spread between the Korean Won-stablecoin trading pairs. Although absolute monthly numbers do not represent a liquidity crisis, this trend erodes the competitive position of domestic exchanges and creates incentives for users to permanently keep assets offshore.

This also raises regulatory issues. South Korean authorities have from time to time expressed their intention to expand the scope of allowed activities-including potential security token issuance and institutional custody liberalization-but have not yet issued a specific timetable. Unless local exchanges can offer a suite of products comparable to Binance, Bybit or decentralized networks, outflows are likely to continue regardless of Bitcoin price movements. Developer activity on top blockchains (shown in recent ecosystem rankings) shows that innovation is still concentrated on chains that Korean platforms cannot integrate seamlessly.

What is unclear is how long regulators are willing to tolerate such outflows. Even if the scale is manageable, such capital flight is incompatible with a country that has historically been wary of currency control and financial stability. If the outflow of stablecoins continues into 2027, pressure for legislative reform will increase-especially as global markets provide a clearer path for South Korean institutions to participate. Currently, 18 months of continuous outflows are just a data point, but it is also a silent indicator: product isolation comes at a cost, and this cost is accumulating every month.
