The U.S. Department of the Treasury recently published the 2023 DeFi Illicit Finance Risk Assessment, the first illicit finance risk assessment conducted on decentralized finance (DeFi) in the world. The assessment considers risks associated with what are commonly called DeFi services. [i]

Decentralized finance (DeFi) has gained significant attention and popularity in recent years, as it promises to revolutionize the traditional financial system by offering open, transparent, and decentralized financial services. However, with the rapid growth of DeFi, there are also emerging risks and concerns that regulatory authorities, including the U.S. Treasury, are closely monitoring with the potential regulatory challenges associated with this innovative technology.

DeFi refers to a set of financial applications built on blockchain networks that operate without intermediaries, allowing users to interact with financial services directly. These services include lending and borrowing, decentralized exchanges, yield farming, and other forms of financial transactions. While DeFi has the potential to disrupt the traditional financial system and offer new opportunities, it also presents unique risks and challenges that regulators are grappling with.

However, like any emerging technology, DeFi also presents risks, including the potential for illicit financial activities, which have caught the attention of regulators and policymakers. The U.S. Treasury Department, as a key regulatory authority in the United States, has been closely monitoring the development of DeFi and its potential impact on illicit finance. In 2023, the Treasury released a DeFi Illicit Finance Risk Assessment, which provides insights into the risks associated with DeFi platforms and highlights the need for robust compliance measures to mitigate these risks.


DeFi operates in a decentralized and global environment, which makes it challenging for regulators to oversee and regulate. Unlike traditional financial intermediaries, DeFi platforms do not have a central entity or a physical presence, making it difficult for regulators to apply traditional regulatory frameworks. The U.S. Treasury and other regulatory authorities are actively assessing how to regulate DeFi to ensure that it operates in compliance with existing financial laws, including anti-money laundering (AML), know-your-customer (KYC), and other regulatory requirements.

DeFi platforms often involve complex financial products and services, and investors may not fully understand the risks involved. There is a lack of consumer protection measures, such as regulatory oversight, investor disclosures, and dispute resolution mechanisms, which could expose retail investors to significant risks. Safeguarding investor interests and ensuring that adequate investor protection measures are essential in the rapidly evolving DeFi space.

DeFi platforms are also built on blockchain technology, which is still relatively new and untested in terms of operational resilience and security. Smart contracts, which are the self-executing codes that power DeFi platforms, are vulnerable to coding errors, security breaches, and other technical risks. There is also a real concern about the operational risks associated with DeFi platforms and the potential systemic risks they could pose to the broader financial system.

Operating in a global and interconnected market, and the lack of transparency, standardization, and regulation could pose risks to market integrity. The absence of clear rules and regulations may lead to market manipulation, insider trading, and other unfair practices that could harm market participants. It is essential to ensuring platforms operate in a fair, transparent, and orderly manner to protect the integrity of the financial markets.

DeFi platforms are interconnected and rely on various protocols, smart contracts, and liquidity pools, which could introduce systemic risks to the financial system. A failure or vulnerability in one DeFi platform could potentially impact the entire ecosystem, leading to a cascading effect.

The Treasury's DeFi Illicit Finance Risk Assessment highlights several key areas of concern:

  1. Money laundering: DeFi platforms allow users to transact and exchange digital assets without traditional financial intermediaries, making it difficult to track the source and destination of funds. This can create opportunities for money laundering, where illicit funds are converted intocryptocurrencies and then laundered through complex transactions across different DeFi platforms, making it challenging to trace and detect suspicious activities.

  2. Terrorist financing: DeFi platforms could potentially be exploited for terrorist financing, where illicit funds are used to support terrorist activities. The decentralized nature of DeFi platforms makes it difficult to detect and prevent such activities, as transactions can be conducted anonymously and without the need for traditional identification or verification processes.

  3. Fraud and scams: DeFi platforms are susceptible to fraud and scams, where users can fall victim to fake or malicious DeFi projects that promise high returns but ultimately result in financial losses. These fraudulent activities can erode investor confidence in the DeFi ecosystem and undermine its legitimacy.

  4. Regulatory compliance: DeFi platforms operate in a rapidly evolving regulatory landscape, with varying levels of compliance requirements in different jurisdictions. The lack of clear regulatory frameworks and standards for DeFi platforms can create compliance challenges, including issues related to anti-money laundering (AML), know-your-customer (KYC), and other regulatory obligations.

In light of these risks, the U.S. Treasury's 2023 DeFi Illicit Finance Risk Assessment emphasizes the need for robust compliance measures to mitigate the risks associated with DeFi platforms. Compliance plays a crucial role in ensuring that DeFi platforms operate in a transparent, secure, and compliant manner, and that they do not facilitate illicit financial activities. DeFi platforms should implement effective compliance programs that include:

  1. AML and KYC procedures: DeFi platforms should establish clear AML and KYC procedures to verify the identity of users and detect and prevent money laundering and terrorist financing activities. This may include implementing transaction monitoring systems, conducting customer due diligence, and reporting suspicious activities to regulatory authorities.

  2. Fraud detection and prevention: DeFi platforms should implement fraud detection and prevention measures to detect and prevent fraudulent activities, such as fake projects, scams, and other malicious activities. This may include conducting thorough due diligence on DeFi projects listed on the platform, monitoring for suspicious activities, and educating users about potential risks.

  3. Regulatory compliance: DeFi platforms should ensure compliance with relevant regulations, including AML, KYC, and other regulatory requirements in the jurisdictions where they operate. This may involve staying updated with regulatory developments, establishing compliance policies and procedures, and maintaining records of compliance activities.

  4. Risk management: DeFi platforms should implement robust risk management practices to identify, assess, and mitigate risks associated with their operations. This may include conducting risk assessments, implementing risk mitigation measures, and monitoring and reporting on risk-related activities.
