South Korea Advances Travel Rule to Cover Smaller Crypto Transfers

South Korean financial regulators are urging a tightening of crypto compliance rules, focusing on the circumstances under which exchanges and other service providers must pass transaction details between each other. The Financial Intelligence Unit (FIU) has proposed expanding the scope of the FATF “Travel Rule” to cover smaller cryptocurrency transfers, according to an announcement posted Monday by the agency.

The change matters because the Travel Rule is built to make digital asset movements easier to trace across platforms—an AML (anti-money laundering) control designed to reduce the anonymity that can arise when funds move from one exchange or custodian to another.

Key takeaways

• The South Korean FIU wants Travel Rule reporting obligations extended to smaller crypto transfers, beyond the current threshold already in force.
• The FIU said responsibilities should apply to both sending and receiving crypto asset service providers (CASPs) to reduce cross-border information gaps.
• Regulators also highlighted the need for stronger enforcement against offshore and unregistered platforms to limit regulatory arbitrage.
• In parallel, FATF approved a report assessing DeFi-related risks, reflecting growing global attention on how decentralized systems fit into AML frameworks.

FIU pushes for Travel Rule coverage on smaller transfers

At a FATF plenary meeting in Paris last week, the South Korean FIU raised proposals to expand Travel Rule requirements to smaller crypto transfers, the FIU said in its Monday announcement. The Travel Rule is a global AML standard under which crypto exchanges and other CASPs share sender and recipient information for transfers that exceed specified thresholds.

South Korea already applies Travel Rule obligations to transfers above 1 million won (about $650), according to the FIU’s references to existing policy from the Financial Services Commission. The latest proposal would lower the compliance trigger by extending reporting requirements to smaller transactions.

From an investor and market-structure perspective, lowering thresholds can increase the number of transactions that fall under compliance screening. While this is aimed at strengthening traceability and deterrence, it also raises the likelihood that exchanges will need to adapt their monitoring, record-keeping, and operational workflows for a broader set of transfers.

Closing cross-border gaps: both senders and receivers

Beyond threshold size, the FIU also argued that Travel Rule obligations should extend across the full transfer lifecycle. Specifically, it said requirements should apply to both originating and receiving CASPs, a move intended to close practical gaps in information exchange during cross-border transfers.

Travel Rule implementation often runs into difficulties at the edges of jurisdiction and counterparties—particularly when one side of a transaction routes funds through providers operating under different regulatory regimes. By emphasizing obligations for both ends of a transfer, the FIU’s approach targets an area that can undermine AML effectiveness even where rules exist on paper.

The FIU also urged stronger action against offshore and unregistered platforms. It cited increased misuse in illicit finance cases and warned that differences in licensing and supervision can encourage regulatory arbitrage—where actors structure operations to benefit from weaker oversight.

FATF’s uneven implementation keeps compliance pressure on regulators

In its broader context, the FIU’s proposals are part of ongoing efforts to implement FATF Recommendation 15, the international standard that brings AML measures to crypto assets and CASPs. FATF updated parts of its approach in 2019, aiming to make crypto closer to the compliance expectations applied to traditional financial transfers.

However, a targeted FATF update in 2025 suggests that global execution remains uneven. The assessment found that 49% of jurisdictions were only partially compliant with requirements for CASPs and that 21% were non-compliant as of April 2025. That leaves roughly 29% of jurisdictions rated as largely compliant or compliant.

This matters because incomplete or inconsistent implementation can create compliance asymmetries across major markets. Even if one country tightens its rules—such as by reducing Travel Rule reporting thresholds—effectiveness can still be limited if counterpart providers in other jurisdictions do not apply equivalent obligations.

In other words, South Korea’s push reflects a more general FATF challenge: the need to harmonize operational standards internationally, not just to adopt rules domestically.

FATF also adopted a report on DeFi risks

Alongside the Travel Rule discussions, FATF approved a report examining risks linked to decentralized finance (DeFi), the FIU said. FIU Commissioner Lee Hyung Ju welcomed the DeFi-related adoption during FATF deliberations, according to the announcement.

At the same time, the FIU commissioner pointed to a fundamental issue behind regulatory arbitrage: differences between jurisdictions in licensing, supervision, and offshore oversight. The implication is that even as global bodies refine risk frameworks for new sectors, enforcement capacity and regulatory design remain crucial to closing loopholes.

For users and builders, DeFi-focused assessments are important because they influence how regulators may expect exchanges, custodians, and other intermediaries to handle exposure to decentralized protocols—particularly where assets and users interact with both on-chain and off-chain infrastructure.

Readers should watch next for how South Korea translates the FIU’s proposals into concrete policy changes—especially whether the threshold adjustment will be paired with expanded requirements for CASPs on both sides of transfers. More broadly, the direction of FATF implementation in 2025 and beyond will be key to determining whether rising compliance expectations are becoming more consistent worldwide or remain patchy across major jurisdictions.
