The digital asset ecosystem is becoming a target for illicit finance. The U.S. Treasury Department is drawing industry attention by proposing a concrete and innovative legal framework to effectively block illicit financial activities occurring within the digital asset ecosystem. The report, "Innovative Technologies to Counter Illicit Finance Involving Digital Assets," submitted to Congress in March 2026, directly addresses the risks of illicit financial activities arising from the anonymity and borderless nature of digital assets. This report fulfills the requirements of the "GENIUS Act" (Promoting and Establishing U.S. Stablecoin Innovation Act), analyzing innovative technologies used in illicit finance and outlining current regulatory gaps and necessary legislative measures. With the rapid growth of the digital asset market, new forms of illicit activities that are difficult to detect with existing financial regulatory frameworks have increased. The Treasury Department is therefore emphasizing the need for comprehensive regulatory measures to address these challenges. One of the report's most crucial proposals is the establishment of a "hold law" specifically tailored for digital assets. This law would grant clear legal authority to digital asset service providers, particularly exchanges and platforms, to temporarily freeze funds when signs of illicit activity are detected. Currently, one of the biggest challenges faced by digital asset platforms is the lack of clear legal grounds to block or freeze suspicious transactions, even when detected. This legal vacuum has repeatedly allowed illicit funds to be moved elsewhere before investigations can even begin. If the hold law is introduced, digital asset platforms will be able to legally freeze suspicious funds during ongoing investigations, thereby acquiring practical means to preemptively block illicit activities and preserve related evidence. This is expected to significantly enhance the ability to respond to criminal activities that exploit digital assets, such as money laundering, terrorist financing, and sanctions evasion. The Treasury Department also proposed establishing a new category of "digital asset-specialized financial institutions" under the Bank Secrecy Act (BSA) and updating existing regulatory definitions to reflect the new business models of digital asset service providers. The existing BSA was designed primarily for traditional financial institutions, limiting its ability to adequately regulate new forms of financial services such as digital asset platforms, decentralized finance (DeFi) protocols, and cryptocurrency wallet services. The creation of a new category acknowledges the unique characteristics of the digital asset ecosystem while establishing a legal basis to clearly impose anti-money laundering (AML) and counter-terrorist financing (CTF) obligations. This will enable digital asset financial institutions to fulfill obligations such as Know Your Customer (KYC), Suspicious Activity Reports (SARs), and transaction record keeping within a clear legal framework. Strengthening regulations on cross-border fund movements is also a significant proposal. The Treasury Department recommended granting itself the authority to restrict or condition certain cross-border "transmittals of funds" not covered by existing money transmission regulations. While the borderless nature of digital assets offers innovative advantages, it also presents a vulnerability where illicit funds can move freely outside the jurisdiction of regulatory authorities. The Core of the 'Hold Law': Blocking Illicit Fund Flows Stricter monitoring and control over cross-border digital asset movements are particularly necessary to prevent funds from flowing into sanctioned countries or organizations. The authority proposed by the Treasury Department would allow it to restrict certain types of cross-border digital asset transactions or require additional verification procedures when necessary to protect national security and the integrity of the financial system. In addition, the Treasury Department stated that it would implement a data framework to combat illicit finance and review the Financial Stability Board's (FSB) recommendations on banking and non-banking regulation and supervision by early 2027. The FSB is an international body for financial regulatory cooperation, developing global regulatory standards related to digital assets. The U.S. Treasury Department's commitment to actively review and implement the FSB's recommendations demonstrates its intent to pursue international harmonization in digital asset regulation. The establishment of a data framework is a key element in enhancing the transparency of the digital asset ecosystem and providing the technical foundation to track illicit activities. While all transactions are recorded due to the nature of blockchain technology, sophisticated data analysis systems and standardized reporting frameworks are required to effect
