The Korea Financial Intelligence Unit (KoFIU) recently issued a total of approximately 355 billion KRW (about 260 million USD) in anti-money laundering fines to the five major domestic exchanges: Upbit, Bithumb, Coinone, Korbit, and Gopax, igniting discussions on local market and global compliance. This is one of the largest administrative penalties imposed on cryptocurrency service providers in South Korea since the revision of the Specific Financial Transaction Information Reporting and Utilization Act (Special Act) in 2021, marking the official entry of the country's compliance review into the "heavy hammer landing" phase. With the fines imposed, the five platforms must complete system rectifications, enhance internal controls, and reporting mechanisms within the following months, facing substantial tests on short-term profitability and mid-term business models, while the overall regulatory framework for South Korea's cryptocurrency industry enters a new cycle of "from filing to accountability."

Overview of Fines and Impact

● Penalty Subject and Scale: KoFIU announced administrative fines totaling approximately 355 billion KRW against five major exchanges, with fines for individual platforms ranging from several hundred million to several billion KRW, far exceeding previous sporadic penalties against smaller platforms, seen as the starting point for "systematic rectification."
● Compliance Basis: The fines are based on the revised Specific Financial Transaction Information Reporting and Utilization Act, focusing on core anti-money laundering (AML) issues such as insufficient KYC implementation, missing or delayed suspicious transaction reports (STR), and inadequate monitoring of high-risk jurisdiction addresses.
● Comparison with Revenue: Taking Upbit's parent company Dunamu as an example, its annual revenue in recent years is at the 1 trillion KRW level, with net profit significantly relying on transaction fees. Fines in the hundreds of millions to billions of KRW equate to a direct consumption of double-digit percentages of annual profits, visually impacting profitability.
● Distinction between Administrative and Criminal: This round of penalties primarily consists of administrative fines + rectification orders, with no simultaneous announcement of criminal prosecution information, indicating that the current regulatory focus is on "correcting behavior and raising thresholds," rather than a blanket exit of core platforms.
● Background of Liability Reserves: Previously, leading platforms in South Korea had accumulated approximately 190 million USD in liability reserves after multiple security and compliance incidents, and this 260 million USD level fine will further increase the cost items related to compliance and risk control on their balance sheets.

Main Types of Violations and Regulatory Logic

● Insufficient KYC Depth: Some platforms were pointed out for not conducting enhanced due diligence (EDD) on high-net-worth users and accounts with frequent large transfers, especially when funds were transferred across borders multiple times or interacted with high-risk jurisdictions, lacking multi-dimensional identity verification and proof of funds sources.
● Gap in Suspicious Transaction Reporting: KoFIU determined that several platforms failed to submit suspicious transaction reports within the statutory time limits when faced with on-chain abnormal transfer patterns (split transfers, frequent small amounts, rapid address rotation, etc.), or lacked sensitivity in identifying typical money laundering patterns.
● Incomplete Sanction and Blacklist Screening: Research briefs indicate that South Korean regulators have repeatedly emphasized the need to access FATF high-risk jurisdiction lists, UN sanction lists, and other multi-source blacklists, but some platforms have technical and procedural gaps in on-chain address and blacklist entity association analysis.
● Weak Third-Party Cooperation Regulation: Some partners, including upstream custody and downstream payment channels, were pointed out for lacking AML controls equivalent to those of the main platform, and exchanges did not establish sufficient review and audit mechanisms, bearing joint responsibility for the risks of outsourced or cooperative businesses.
● Insufficient Internal Compliance Team and System Investment: The brief mentioned that some exchanges' compliance personnel allocation is severely mismatched with trading volume and asset scale, relying on traditional bank-level tools for on-chain monitoring, failing to cover new risk scenarios involving multiple chains, addresses, and wallets.
● Regulatory Logic: South Korea's current review closely follows FATF's Travel Rule and VASP Guidelines, upgrading from "formal filing" to "substantive review," focusing on:
● Ensuring closure of on-chain and off-chain identity information;
● Increasing the visualization of large and cross-border transactions;
● Preventing local platforms from becoming stepping stones for global gray industries and sanction evasion.

Pressure on Exchanges' Finances and Business Structure

● Direct Financial Impact:
● The fine amount must be accounted for in a lump sum or paid in installments in the short term, directly squeezing profit margins in the financial reports for the 2024-2025 fiscal years;
● For medium-sized exchanges, fines in the hundreds of millions of KRW could lead to a halving or even loss of net profit for the year.
● Continuous Increase in Compliance Investment:
● To meet rectification requirements, the five major platforms need to increase budgets for KYC system upgrades, on-chain monitoring tool procurement, and compliance team expansion;
● The brief indicated that some platforms expect compliance-related OPEX to rise to 5%-10% of revenue, bringing them closer to traditional financial institutions.
● Contraction of Product and Regional Strategies:
● For high-risk cryptocurrencies, anonymous technologies, or difficult-to-penetrate cross-border funding channels, platforms may choose to actively delist, raise thresholds, or limit leverage and derivatives exposure;
● The opening and trading permissions for users from high-risk countries/regions will be significantly tightened in the short term to reduce the likelihood of being classified as "high-risk VASP" by regulators.
● Rate and User Experience Trade-offs:
● To offset costs, platforms may have the motivation to raise transaction fees, reduce rebates, and cut marketing budgets;
● Enhanced KYC and risk control logic may lead to longer account opening times and increased withdrawal review frequency, impacting the operational fluidity for retail and market makers.
● Increased Expectations for Mergers and Exits:
● The brief mentioned that weaker platforms are more likely to be acquired or exit under the new round of compliance cost pressure, potentially accelerating the concentration of the industry towards entities with stronger assets and more complete compliance systems.

South Korea's Regulatory Path: From Special Act to Substantive Accountability

● Revision of the Special Act and Implementation of the VASP Framework:
● Since 2021, South Korea has included cryptocurrency exchanges under the Specific Financial Transaction Information Reporting and Utilization Act, requiring them to complete FIU reporting, bank real-name account connections, and anti-money laundering system construction;
● Approval as a Virtual Asset Service Provider (VASP) has become a prerequisite for platform operations, but early compliance was more focused on "formal compliance."
● Strengthening Travel Rules and On-Chain Traceability:
● With the advancement of the FATF Travel Rule, South Korea requires local platforms to transmit and verify identity information of both parties in transactions exceeding 100,000 KRW across platforms or borders;
● This has pushed exchanges to integrate more on-chain analysis and blacklist screening tools, but also exposed issues of system compatibility and insufficient data sharing.
● From Bank Regulation to Direct Regulation:
● The early regulatory path achieved "indirect control" mainly through commercial banks opening and renewing accounts for exchanges;
● This round of 260 million USD fines indicates that KoFIU is transitioning from relying on bank risk control to directly examining VASP internal controls and technical systems.
● Aligning with Global Regulatory Rhythm:
● South Korea is gradually aligning with EU MiCA, US FinCEN/Fed gray area regulatory practices in dimensions such as anti-money laundering, customer asset segregation, and listing reviews;
● The goal is to maintain the local trading volume and innovation activity while avoiding being placed on the FATF gray list, preserving the international credibility of its financial system.
● Future Expansion to More Business Lines:
● The brief suggests that the current focus on spot matching and custody business is likely to extend to more complex business forms such as staking, yield products, and custody as a service (CaaS);
● This will require platforms to further align their accounting treatment, information disclosure, and risk isolation with the standards of the securities and fund industries.

Market Sentiment and Divergence of Opinions

● Optimistic/Supportive: Believing this is a long-term benefit and an opportunity for industry upgrade
● Viewpoint 1: Large fines will quickly eliminate platforms lacking in technology and capital strength, strengthening concentration at the top and helping to build more stable liquidity and depth;
● Viewpoint 2: Strengthening the AML framework in South Korea can alleviate international regulatory concerns about local platforms, enhancing their "investability" in global institutional funds;
● Viewpoint 3: Short-term profit pressure in exchange for a higher compliance moat, with the potential to gain premiums in custody, institutional market making, and compliant inflows and outflows in the future.

● Pessimistic/Opposing: Concerned that costs will crush innovation and lead to user outflow
● Viewpoint 1: The 260 million USD fine and continuously rising compliance OPEX will erode platforms' R&D and product innovation budgets, impacting local project issuance and new business attempts;
● Viewpoint 2: More stringent KYC and monitoring may drive some users to turn to offshore platforms or on-chain DEXs with looser regulations, weakening South Korea's position as a trading and liquidity center;
● Viewpoint 3: If the regulatory pace continues to intensify without a clear sandbox or innovation exemption mechanism, local entrepreneurial teams and developers may choose to relocate their project registrations to other jurisdictions.

This penalty and rectification are not isolated actions but rather a structural adjustment made by South Korea under the dual pressures of global compliance competition and domestic financial stability demands. As exchanges shift from "prioritizing traffic and trading volume" to "balancing compliance and capital consumption," their profit models, product designs, and even risk control cultures must be reshaped. For South Korea and the broader Asian market, if leading platforms can complete system upgrades and maintain competitiveness under the new rules, they will gain an advantage in the next round of institutionalization and global capital entry; conversely, participants unable to bear high compliance costs and technical thresholds will be forced to exit or be acquired, reshaping the industry landscape.

In the short term, the market will focus on the rectification progress of the five major platforms, the impact of additional disclosed financial reports, and whether KoFIU will extend similar standards to small and medium VASPs and new business forms. In the medium term, whether South Korea can find a balance between maintaining trading activity and meeting FATF and major trading partners' compliance expectations will directly determine its voice and pricing power in the global cryptocurrency financial landscape. For investors and practitioners interested in this market, understanding and predicting changes in compliance cost curves is becoming as important as understanding price curves.
