South Korea is escalating its oversight of cryptocurrency transfers involving overseas platforms, introducing additional compliance requirements for domestic digital-asset users as authorities expand anti-money-laundering controls and restrict access to unregistered foreign exchanges. The measures build on South Korea's March 2021 amendment to the Act on Reporting and Using Specified Financial Transaction Information, which first required all virtual-asset service providers operating in the country to register with the Korea Financial Intelligence Unit (KoFIU) and comply with AML obligations.

Google Play Restrictions Expand

The Bybit and OKX applications have been removed from South Korea's Google Play Store. Bybit became unavailable for new installations in July, with OKX following later that same month. The restrictions specifically target overseas virtual-asset service providers that have not registered with South Korea's Financial Intelligence Unit.

The removals fall under a broader Google Play policy framework designed to prevent unregistered overseas exchanges from offering new downloads within South Korea. Existing users may retain access in certain cases, though app updates could be limited.

These measures do not constitute a blanket prohibition on overseas exchanges. Users can still reach some platforms through web browsers or alternative channels, subject to regulatory decisions and platform availability. South Korea has historically ranked among the world's largest retail cryptocurrency markets by trading volume, making compliance with its registration regime a significant consideration for global exchanges seeking access to local users.

10 Million Won Transfer Threshold

South Korea is also preparing stricter reporting requirements for transfers involving overseas virtual-asset exchanges and digital-wallet providers.

Under revised rules scheduled to take effect on August 20, domestic virtual-asset service providers must report all transfers of 10 million won or more directed to overseas exchanges or wallet services to the Korea Financial Intelligence Unit. This obligation applies irrespective of the transaction's assessed risk level.

The government states that the measure is intended to bolster monitoring of overseas transactions and mitigate money laundering risks. The 10-million-won threshold—approximately $7,500—aligns with existing cross-border cash reporting requirements that Korean banks already apply under the Foreign Exchange Transactions Act, signaling an effort to bring cryptocurrency transfers into closer parity with traditional financial reporting standards.

Strengthened Customer Due Diligence

The new regulatory framework will also reinforce customer due diligence obligations. Virtual-asset providers will assume expanded responsibilities for verifying the accuracy of customer information, while higher-risk customers and services may face more stringent checks.

This could result in additional questions or documentation requirements for certain transactions. However, available official guidance does not impose a universal mandate requiring users to demonstrate ownership of an overseas exchange account for every transfer exceeding 10 million won.

The enhanced diligence requirements also reflect South Korea's implementation of the Financial Action Task Force's Travel Rule, which obliges VASPs to transmit originator and beneficiary information for qualifying transfers. South Korea's approach represents part of a wider international trend, as jurisdictions including Japan, Singapore, and the European Union have similarly tightened cross-border crypto oversight in line with evolving FATF standards. For local traders, the practical consequences will likely vary based on the specific exchange involved, transaction size, individual risk profile, and the compliance procedures adopted by domestic platforms.
