South Korea FIU Urges Wider Travel Rule for Small Crypto Transfers

South Korea’s Financial Intelligence Unit (FIU) has pressed for tighter global reporting standards for cryptocurrency transfers, urging a broader application of the FATF “Travel Rule” to reduce gaps in cross-border anti-money laundering (AML) controls. The push reflects concerns that current implementation leaves smaller transactions and counterparties outside meaningful compliance coverage.

During a FATF plenary session in Paris last week, the FIU proposed expanding the Travel Rule obligations to smaller crypto transfers and called for more comprehensive coverage across both originating and receiving crypto asset service providers (CASPs). The FIU also highlighted the continuing policy divergence that can enable regulatory arbitrage, while FATF approved additional work related to decentralized finance (DeFi) risk.

Key takeaways

• South Korea’s FIU urged expanding FATF Travel Rule requirements to cover smaller crypto transfers, not only large-value movements.
• The FIU recommended that Travel Rule obligations apply to both originating and receiving CASPs to reduce cross-border compliance gaps.
• FIU officials called for tougher scrutiny of offshore and unregistered crypto platforms, citing increased misuse in illicit finance cases.
• FATF approved a DeFi-focused report, while South Korea’s FIU warned that jurisdictional licensing and supervision differences continue to drive regulatory arbitrage.

Expanding the Travel Rule: from thresholds to broader coverage

The FIU’s proposal focuses on the practical operation of the FATF Travel Rule, an AML standard intended to improve traceability for crypto transfers by requiring exchanges and other CASPs to transmit relevant sender and recipient information when transfers exceed defined thresholds. According to FIU materials, the goal is to ensure that the compliance perimeter is not limited to large transactions that may be more likely to be detected under existing frameworks.

South Korea already applies Travel Rule obligations to crypto transfers above 1 million won (approximately $650). The FIU’s latest recommendation seeks to extend those requirements downward, which would likely increase the number of transfers subject to information-sharing expectations and create additional operational and compliance burdens for regulated firms.

For institutional compliance programs, this matters because threshold-based controls can create exploitable boundaries. Reducing the value cutoffs can change how monitoring systems are configured, what data fields are required, and how firms document and evidence compliance during audits and supervisory reviews.

Closing cross-border gaps: originating and receiving CASPs

Beyond lowering transaction thresholds, the FIU argued that Travel Rule requirements should cover both sides of a transfer. Specifically, it called for obligations to apply to originating and receiving CASPs, reflecting an emphasis on end-to-end information flows rather than fragmented compliance limited to only one entity in a transaction chain.

The FIU’s position is aligned with a broader policy objective: AML regimes are only as effective as the continuity of controls between jurisdictions. If receiving CASPs do not have compatible obligations—or if counterparties in different regulatory environments are not required to provide or obtain the same information—then traceability can be lost even when rules exist at the point of origin.

The FIU also tied its recommendations to the broader problem of cross-border regulatory fragmentation. It warned that differences in licensing structures, supervisory approaches, and offshore oversight can produce inconsistent enforcement outcomes—an environment in which regulatory arbitrage becomes a systemic risk rather than an edge case.

Enforcement emphasis: unregistered platforms and offshore activity

In addition to tightening data-sharing expectations, the FIU called for stronger action against offshore and unregistered crypto platforms. The FIU linked this to what it characterized as heightened misuse in illicit finance cases, as well as the risk that criminals can shift activity to venues with weaker oversight.

For regulated market participants, this direction suggests greater compliance attention not only to transaction monitoring but also to counterparty risk management. Institutional firms typically implement controls to assess whether counterparties are properly licensed or subject to effective supervision, and proposals like this can raise the expectation that those controls remain robust even when counterparties are operating abroad.

From a compliance and legal perspective, stronger action against unregistered platforms can also increase pressure on regulated entities to demonstrate due diligence regarding onboarding, ongoing monitoring, and contractual safeguards. It may affect how firms interpret “compliance reach” when interacting with cross-border service providers whose regulatory status or supervision quality is uncertain.

FATF also advances work on DeFi risk and implementation unevenness

Alongside the Travel Rule discussion, FATF approved a new report examining risks associated with decentralized finance (DeFi), according to FIU reporting. FIU Commissioner Lee Hyung Ju welcomed adoption of the DeFi-related work but emphasized that much of the regulatory arbitrage seen across jurisdictions stems from structural differences—particularly the divergence in licensing, supervision, and offshore oversight.

The Travel Rule debate also comes against the backdrop of FATF’s broader assessment of implementation. The FIU referenced FATF’s update indicating that compliance with parts of Recommendation 15 remains inconsistent globally, even years after FATF extended its AML framework to cover crypto assets and CASPs.

According to a FATF-targeted update cited by the FIU for April 2025, 49% of jurisdictions were assessed as only partially compliant with requirements for CASPs, 21% were rated non-compliant, and roughly 29% were rated largely compliant or compliant. The unevenness is significant because global standards depend on coordinated implementation to be effective in practice—especially for cross-border activity where regulated and less-regulated actors may interact.

This gap also matters for supervised entities operating in multiple markets. When compliance expectations differ across jurisdictions, firms may face higher compliance costs and greater legal uncertainty in determining which standard applies to particular counterparties and transaction pathways.

Policy context: seven years after FATF expanded the framework

The FIU’s proposals are part of ongoing discussions on implementing FATF Recommendation 15, the international standard updated in 2019 to bring AML measures to crypto assets and CASPs. Seven years on, FATF has continued to refine its understanding of how the Travel Rule should be applied operationally and what gaps remain in implementation.

For South Korea’s regulated sector, the FIU’s stance indicates a move toward closer alignment with stronger, more expansive interpretations of the Travel Rule. Since South Korea already implements Travel Rule controls for transfers above a defined threshold, expanding coverage to smaller transfers would represent an escalation in the scope of information-sharing obligations.

However, the policy question that remains open is how jurisdictions will calibrate thresholds and practical implementation requirements without creating disproportionate operational friction. Differences in data availability, transaction routing mechanics, and system interoperability can influence whether the compliance intent of the Travel Rule translates into consistent implementation at scale.

Closing perspective

With FATF’s continued work on Travel Rule implementation and DeFi risk, regulators are signaling that AML expectations for digital-asset activity will likely tighten over time—particularly around information-sharing coverage and supervision of cross-border counterparties. For compliance leaders and legal teams, the next developments to monitor include how FATF operational guidance evolves and whether South Korea and other jurisdictions move toward lower thresholds and broader CASP-to-CASP obligations.
