South Korea’s Assembly Passed a Crypto AML Registration Framework

South Korea’s National Assembly passed an amendment on March 5, 2020 that brought virtual-asset businesses into the country’s anti-money-laundering framework. The vote approved the proposed amendment to the Act on Reporting and Using Specified Financial Transaction Information, creating statutory definitions for “virtual assets” and “virtual-asset service providers” and establishing a reporting regime overseen by the Korea Financial Intelligence Unit.

The verified development was parliamentary passage, not immediate commencement. On March 5, the measure still required executive processing and promulgation, and major operating details remained for a presidential decree. That distinction matters because some contemporaneous coverage described the vote as making cryptocurrency “fully legal.” The text supports a narrower conclusion: South Korea had chosen to regulate covered crypto businesses for anti-money-laundering and counter-terrorist-financing purposes.

What the Assembly approved

The official legislative record says the measure passed the National Assembly’s plenary session on March 5, 2020. Its stated purpose was to address the money-laundering and terrorist-financing risks associated with the anonymity of virtual-asset transactions and to implement standards promoted by the Group of 20 and the Financial Action Task Force.

The amendment defined a virtual asset as an electronic representation with economic value that can be traded or transferred electronically, subject to listed exclusions. It also defined covered businesses around activities including buying and selling virtual assets, exchanging one virtual asset for another, custody or management, and brokerage or arrangement of trades.

Covered operators would have to report identifying business information to the Korea Financial Intelligence Unit. The framework also required measures supporting customer due diligence, suspicious-transaction reporting and the separation and management of customer transaction records. Financial institutions dealing with a virtual-asset business would have to check its reporting status and other compliance conditions, and refuse a relationship in specified noncompliance or money-laundering-risk circumstances.

The bill provided criminal consequences for operating without the required report. A contemporaneous legal analysis published on March 9 described the maximum as five years’ imprisonment or a fine of 50 million won. That figure described the statutory ceiling for an unreported business, not a penalty imposed on any exchange on March 5.

Regulation was not blanket approval

The institutional significance lay in replacing an incomplete AML perimeter with a defined compliance gateway. Exchanges, custodians and other covered providers could no longer treat access to the banking system as separate from their status under the financial-intelligence regime. Banks, in turn, received explicit verification and refusal duties when serving those businesses.

That did not make crypto legal tender, classify every token as a security or commodity, guarantee an exchange’s license, or establish that customer assets were insured. It also did not resolve market-manipulation, prudential, bankruptcy or broad investor-protection questions. Interpreting the amendment as general legalization would therefore overstate what the National Assembly approved.

The measure also imposed uncertainty. The precise scope of covered providers and some grounds for accepting or rejecting reports depended on implementing rules. Existing businesses were expected to receive a transition period, but the operative calendar depended on promulgation. On March 5, no evidence established which operators would ultimately qualify or how many would leave the market.

Later context

Later official records clarify, without changing the March 5 event. South Korea’s government approved the revision at a cabinet meeting on March 17, 2020, and President Moon Jae-in promulgated Act No. 17113 on March 24. The enacted law was scheduled to take effect one year after promulgation, with existing virtual-asset businesses given a further six months to submit reports.

Those later steps confirm that March 5 was the decisive legislative vote, but not the start of live compliance. The event-day conclusion remains bounded: lawmakers approved an AML and reporting framework for crypto businesses, while implementation and firm-level outcomes were still ahead.
