South Korean exchanges see record $60B crypto outflows as profits shrink
South Korea’s cryptocurrency market ended the second half of 2025 with a striking contradiction: exchanges saw record levels of capital flowing out while user numbers and deposits on local platforms continued to climb. New figures from the Financial Services Commission (FSC) reveal that, beneath the surface of growing retail participation, profitability, trading volumes and overall market value were all under pressure.
Record outflows despite growing participation
According to the FSC, crypto outflows from South Korean exchanges reached 90 trillion won (around $60 billion) in the second half of 2025. That represents a 14% increase compared with the 78.9 trillion won (approximately $52.5 billion) that left domestic platforms in the first half of the year.
Regulators attribute a significant share of these outflows to cross-border and arbitrage-focused activity. The FSC noted that “virtual assets are being transferred abroad for arbitrage and other similar activities,” pointing specifically to foreign trading platforms and private, self-custodied wallets as the primary destinations for these funds.
This means more money is leaving Korean exchanges even as onshore user engagement appears to be rising, suggesting that local platforms are increasingly serving as an on-ramp rather than a final destination for crypto capital.
User accounts and deposits keep climbing
Despite the surge in capital leaving domestic exchanges, the number of accounts on South Korean trading platforms continued to edge higher. By the end of 2025, exchange accounts totaled 11.1 million, a 3% increase from June 2025. The data underscore that interest in digital assets among Korean users remains resilient, even amid volatile prices and regulatory uncertainty.
Customer deposits grew much faster than user accounts. The FSC reported that funds parked on South Korean exchanges jumped 31% in the second half of 2025, reaching 8.1 trillion won (about $5.4 billion). This divergence – rising deposits alongside record outflows – suggests that while new and existing users are bringing fresh capital into the system, a substantial portion is being moved off-exchange soon after.
This pattern points to growing sophistication among local traders, many of whom may be using domestic exchanges primarily for fiat on-ramps before transferring assets to foreign platforms, derivatives venues or cold storage.
Profits fall sharply for exchange operators
The increase in accounts and deposits failed to translate into higher earnings. The country’s 18 operating cryptocurrency exchanges generated 380.7 billion won (about $253.4 million) in operating profit during the second half of 2025. That marks a steep 38% decline from the 617.8 billion won (around $411.2 million) recorded in the first half of the year.
Lower profits indicate that the business model of local exchanges is under strain. Fee-based revenues depend heavily on trading volumes and price volatility. As market activity cooled and digital asset prices softened toward the end of 2025, fee income dropped. At the same time, compliance, security, staffing and technology costs have continued to rise amid tougher regulatory requirements.
For many mid-sized and smaller platforms, this combination of shrinking margins and increasing fixed costs is likely to accelerate consolidation in the industry, leaving only well-capitalized and highly regulated players in the market over the long term.
Trading volumes retreat amid price weakness
Trading activity mirrored the downturn in profitability. The FSC estimated that average daily crypto trading volume on South Korean exchanges fell to 5.4 trillion won (about $3.6 billion) in the second half of 2025 – a 15% decrease from the first half.
Regulators pointed to declining cryptocurrency prices late in the year as a key factor behind subdued activity. When prices trend lower or move sideways for extended periods, retail traders often retreat to the sidelines, leading to fewer transactions, lower leverage usage and reduced interest in altcoins.
For exchanges that depend on high-frequency trading, speculative altcoin cycles and margin products, this cooling of activity can have an outsized impact on revenue. The data suggest that even a modest slowdown in market enthusiasm can significantly hit the bottom line in such a highly competitive sector.
Market capitalization slides from mid-year levels
The overall size of South Korea’s digital asset market also pulled back. The FSC put the country’s crypto market capitalization at 87.2 trillion won (approximately $58 billion) at the end of 2025. This represented an 8% decline compared with the first half of the year.
This drop reflects broader weakness across major cryptocurrencies, not only in Korea but globally. While participation by local users remained relatively robust, lower token prices offset the effect of new capital entering the space.
The market cap figure highlights a core tension: South Korean investors appear willing to hold and buy during dips, but global price cycles still dominate local outcomes. Domestic sentiment and policy can shape participation and flows, yet they cannot fully insulate Korean investors from macroeconomic conditions and international crypto market trends.
A market still below its recent peak
The broader digital asset market remained well below its October 2025 peak, when bitcoin reached an all-time high of roughly $126,080. Since then, a mix of macro headwinds, profit-taking and regulatory scrutiny worldwide cooled the explosive momentum that had previously driven prices higher.
The FSC’s data show that, while user engagement did not collapse alongside prices, weaker valuations and lower trading volumes squeezed the performance of South Korean exchanges in the second half of the year. In effect, the infrastructure continued to grow – more accounts, more deposits – even as the profitability of that infrastructure deteriorated.
This dynamic illustrates the maturing nature of the market: unlike earlier cycles when retail participation could collapse during downturns, interest is now more persistent, but monetizing that interest has become more challenging.
Why funds are moving overseas and off exchanges
The record level of outflows raises a key question: why are so many funds leaving domestic platforms at a time when more Koreans are engaging with crypto?
Several factors likely play a role:
– Arbitrage and cross-border spreads: Price differences between Korean exchanges and overseas platforms can create arbitrage opportunities. Professional traders exploit these gaps by moving assets quickly between jurisdictions.
– Access to product variety: Some foreign platforms offer a wider range of tokens, derivatives and yield products than are available domestically under current rules, incentivizing users to transfer funds abroad.
– Self-custody trends: After multiple global exchange failures and hacks in recent years, a growing share of users prefer holding coins in private wallets rather than on centralized platforms.
– Regulatory considerations: Anticipation of stricter domestic oversight and tax policies can push some investors to hold assets outside local exchanges, even if they continue to use those exchanges as entry and exit points to the fiat system.
These drivers suggest that outflows are not necessarily a sign of collapsing trust in crypto itself, but rather a shift in how and where Koreans choose to store and trade their digital assets.
Implications for regulation and tax policy
The FSC’s findings arrive at a time when South Korea is actively reshaping its crypto regulatory framework, including debates over taxation, investor protection and the classification of various digital assets.
Large capital outflows and rising cross-border activity will likely strengthen arguments for more detailed reporting requirements, tighter oversight of exchange operations and enhanced monitoring of overseas transfers. Regulators may also view the decoupling of growing deposit levels and falling profits as a sign that current market structures are not sustainable without clearer rules and better risk management.
At the same time, policymakers face a balancing act. Excessively restrictive rules could push even more activity offshore, undermining their ability to supervise the market. A more nuanced approach – supporting compliance while allowing competitive innovation – will be critical if South Korea wants to remain a leading crypto hub in Asia.
Strategic challenges for local exchanges
For South Korean exchanges, the data paint a demanding operating environment. Key challenges include:
– Margin compression: With volumes falling and competition intense, cutting trading fees to attract users can erode margins faster than cost savings can keep pace.
– Customer retention: As more users treat local exchanges as simple on- and off-ramps, platforms need new services to keep assets on-site, such as staking, institutional-grade custody or advanced trading tools.
– Regulatory costs: Compliance, licensing, auditing and security standards are all becoming more stringent, raising fixed expenses regardless of market cycles.
– Product differentiation: Offering the same basic spot-trading services as competitors is no longer enough; exchanges need clear value propositions, from better user experience to specialized institutional offerings.
How successfully exchanges adapt to these pressures will determine whether they can turn renewed user interest into sustainable long-term business models.
What this means for South Korean investors
For retail and institutional investors in South Korea, the trends highlighted by the FSC carry several implications:
– Market access is expanding, but risk remains high: Growing account numbers and deposits show that it is easier than ever to enter the market, but falling profits and volumes remind investors that sector health can deteriorate quickly when prices cool.
– Offshore exposure comes with trade-offs: Moving funds abroad may offer better product choice or yields, but it also introduces additional regulatory, legal and counterparty risks.
– Price cycles are still global: Even with strong domestic interest, local markets remain highly exposed to global bitcoin and altcoin cycles, macroeconomic shifts and international policy developments.
– Due diligence is critical: In a landscape of tightening margins for exchanges, investors should scrutinize platform financial health, security practices and regulatory status before committing significant assets.
In sum, South Korea’s crypto sector is evolving from a speculative boom environment to a more complex, regulated ecosystem. Record outflows, rising participation and shrinking profits together signal a market in transition – one where users are more active and informed, but where platforms and regulators must move quickly to keep pace.
