Financial sanctions are a critical tool in global diplomacy, designed to exert economic pressure on rogue states, criminal enterprises, and individuals who violate international norms. Traditionally, sanctions have targeted conventional banking systems, making it difficult for sanctioned entities to access global financial markets. However, the rise of cryptocurrency has introduced a new avenue for sanctions evasion. Cryptocurrencies, with their decentralized nature and relative anonymity, offer sanctioned actors an opportunity to bypass traditional financial restrictions. This article investigates the role of cryptocurrencies in financial sanctions evasion, with a particular focus on nation-state actors like North Korea, Russia, China, and Iran, as well as other entities and individuals exploiting these digital assets for illicit purposes.
The Mechanics of Cryptocurrency Evasion
Cryptocurrencies operate on blockchain technology, which is decentralized and generally resistant to government intervention. The decentralized nature of cryptocurrencies means they are not controlled by any single authority, making it difficult for regulators to enforce sanctions effectively. Additionally, cryptocurrency transactions can be pseudonymous, meaning that the identities of the participants in a transaction are not always easily traceable, which complicates the enforcement of sanctions.
Sanctioned entities can exploit these features to transfer funds across borders, circumventing the traditional financial system that is tightly monitored by governments and international organizations. Peer-to-peer (P2P) exchanges, decentralized finance (DeFi) platforms, and anonymous wallets are often used to evade detection. In some cases, sanctioned actors may engage in complex layering techniques, breaking transactions into smaller, less detectable amounts across multiple exchanges and wallets.
North Korea and Cryptocurrency Theft
North Korea provides a prime example of how a nation-state can use cryptocurrency to evade financial sanctions. The regime has been subjected to heavy international sanctions due to its nuclear weapons program and other human rights abuses. In response, North Korea has turned to cryptocurrency as an alternative means of generating revenue and bypassing these financial restrictions.
The Lazarus Group, a cybercrime group affiliated with North Korea, has been involved in high-profile cryptocurrency thefts, most notably the 2017 WannaCry ransomware attack. In recent years, the group has shifted its focus to cryptocurrency exchanges. In 2022, North Korean hackers stole an estimated $600 million in cryptocurrency from the Ronin Network, which was linked to the popular play-to-earn game “Axie Infinity” (Chainalysis, 2022). These funds were funneled through mixers—services that obscure the origins of cryptocurrency by blending multiple transactions—making it difficult for international authorities to track and recover the stolen assets.
North Korea has also been reported to use cryptocurrency mining as another method of evasion. By mining digital assets like Bitcoin, the regime is able to generate revenue that is not easily traceable through traditional financial systems. These mined cryptocurrencies can then be used to purchase goods or traded for fiat currency without triggering sanctions enforcement mechanisms.
Russia’s Use of Cryptocurrency to Avoid Sanctions
Russia has become a focal point for cryptocurrency-based sanctions evasion, particularly since the economic restrictions imposed following its annexation of Crimea in 2014 and, more recently, the sanctions imposed due to its invasion of Ukraine in 2022. With many Russian oligarchs, businesses, and financial institutions cut off from the global financial system, the use of cryptocurrency has emerged as a vital tool for evading sanctions.
Russian individuals and companies have used cryptocurrency to transfer funds, pay for goods and services, and continue participating in international markets despite being banned from using traditional banking services (Kwon, 2023). Many oligarchs turned to decentralized exchanges and over-the-counter (OTC) brokers to buy and sell cryptocurrencies without going through regulated exchanges. In response to these practices, the U.S. Department of the Treasury and European regulators have begun targeting cryptocurrency exchanges that facilitate transactions with Russian entities. Despite these efforts, the opaque nature of decentralized finance (DeFi) platforms and Russia’s well-established networks of financial facilitators make enforcement challenging.
Additionally, Russia has developed state-backed cryptocurrency projects to further evade sanctions. The Russian government has shown interest in creating a central bank digital currency (CBDC), known as the digital ruble, which could allow it to bypass the global financial system altogether. Russia has also forged deeper ties with countries like Iran and China, exploring the possibility of using cryptocurrency in bilateral trade to avoid the dollar-based international financial system that sanctions typically target (Reuters, 2022).
China’s Involvement in Sanctions Evasion
While China itself is not heavily sanctioned by the international community, it plays a crucial role in facilitating sanctions evasion for its allies, particularly Russia and North Korea. Chinese cryptocurrency exchanges have been linked to facilitating transactions that help sanctioned entities obscure the flow of funds. In several cases, Chinese exchanges have been used to launder cryptocurrency that originated from North Korean cyber-attacks or Russian oligarchs attempting to move their assets out of the reach of Western sanctions.
In addition to private actors, the Chinese government has developed its own digital currency, the Digital Yuan, which it sees as a means to challenge the dominance of the U.S. dollar in international trade and finance. While China has imposed significant regulations on cryptocurrency use within its borders, it has also explored the use of blockchain technology to conduct cross-border transactions with other countries under sanctions. For example, China and Russia have discussed using digital currencies in bilateral trade to reduce their reliance on the SWIFT network, which is often used to enforce sanctions (Bloomberg, 2022).
China has also been implicated in providing cryptocurrency mining equipment to sanctioned countries like Iran and North Korea. By supplying the technology necessary to mine cryptocurrencies, China enables these nations to generate digital assets that can be used to finance imports or traded for fiat currency without triggering sanctions enforcement mechanisms.
Iran’s Cryptocurrency Strategy for Sanctions Evasion
Iran has faced international sanctions for decades due to its nuclear program, human rights violations, and support for terrorist organizations. In response to these crippling sanctions, Iran has turned to cryptocurrency as a tool for circumventing economic restrictions. The Iranian government has embraced cryptocurrency mining as a state-sponsored activity, legalizing mining operations in 2019. Iran’s abundant and inexpensive energy supply has made it one of the world’s leading cryptocurrency mining hubs, allowing the country to generate digital assets that can be used to finance imports and bypass the international banking system.
According to reports, Iran uses cryptocurrencies to fund imports and circumvent the U.S. dollar-based global financial system. In one notable case, Iranian entities used cryptocurrency to facilitate transactions in gray markets, where financial transactions are conducted without going through the formal banking sector (Al Jazeera, 2021). This practice allows Iran to continue trading oil and other goods despite sanctions on its financial institutions and energy sector.
Moreover, Iran’s involvement in cryptocurrency goes beyond mining. The country has developed state-sponsored hacking groups that have been linked to ransomware attacks and cryptocurrency theft. These funds are then used to finance the Iranian government’s operations, including its support for proxy militias in the Middle East.
Sanctioned Individuals and Companies
Beyond nation-state actors like North Korea, Russia, China, and Iran, sanctioned individuals and companies are also exploiting cryptocurrency to bypass financial restrictions. In many cases, these actors use cryptocurrencies to continue conducting business or to move their personal wealth out of jurisdictions where their assets might be frozen. For example, sanctioned Venezuelan officials have reportedly used cryptocurrencies to evade financial restrictions imposed by the United States and other countries (Kessler, 2020). Similarly, Syria has used cryptocurrency to circumvent sanctions and finance its war efforts.
Cryptocurrency also allows for the establishment of cross-border networks, whereby sanctioned companies can obscure the origins of funds by transferring assets through multiple jurisdictions. These networks can involve a combination of cryptocurrency exchanges, shell companies, and unregulated digital asset platforms in jurisdictions with weak regulatory oversight, making it harder for international regulators to trace and seize illicit assets.
Regulatory Gaps and Enforcement Challenges
The global nature of cryptocurrency, coupled with its decentralized structure, creates significant regulatory challenges for governments and international organizations. While countries like the United States and European Union have taken steps to regulate cryptocurrency exchanges and impose anti-money laundering (AML) and know-your-customer (KYC) requirements, enforcement remains difficult due to the borderless nature of digital assets.
One major issue is the existence of unregulated or poorly regulated cryptocurrency exchanges in jurisdictions with weak or non-existent AML/KYC standards. These exchanges become havens for sanctioned actors seeking to launder cryptocurrency or exchange it for fiat currency. Moreover, decentralized exchanges (DEXs), which allow users to trade cryptocurrencies directly with each other without intermediaries, have gained popularity. These DEXs operate without centralized oversight, making it nearly impossible to enforce sanctions on transactions taking place within these platforms.
Cryptocurrency mixing services add another layer of complexity to enforcement efforts. By mixing multiple transactions together, these services make it exceedingly difficult for authorities to trace the origin of the funds. Many sanctioned actors also turn to privacy coins such as Monero or Zcash, which are designed with enhanced anonymity features, further complicating sanctions enforcement.
International Efforts to Combat Cryptocurrency Sanctions Evasion
Despite these challenges, international efforts are underway to address the misuse of cryptocurrency for sanctions evasion. The Financial Action Task Force (FATF), an intergovernmental organization that sets global standards for anti-money laundering, has issued guidance for the regulation of virtual assets. FATF’s “travel rule” requires cryptocurrency exchanges to collect and share information about the participants in transactions, similar to the requirements imposed on traditional financial institutions.
The United States has also begun to take aggressive action against sanctioned actors using cryptocurrency. The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) has designated several cryptocurrency addresses linked to sanctioned individuals, preventing U.S. citizens and entities from engaging in transactions with these addresses. In 2021, OFAC sanctioned two Iranian individuals who were involved in a ransomware scheme that used cryptocurrency payments to avoid detection (U.S. Department of the Treasury, 2021).
Other countries and international organizations have followed suit, with increased cooperation between governments and cryptocurrency exchanges to track and freeze illicit assets. However, the rapid evolution of the cryptocurrency industry, including the rise of DeFi platforms and privacy-enhancing technologies, continues to outpace regulatory frameworks, leaving significant loopholes for sanctioned actors to exploit.
Cryptocurrency has undoubtedly provided new opportunities for sanctioned individuals, companies, and nations to evade financial restrictions. The decentralized, pseudonymous nature of digital assets makes them attractive to those seeking to bypass traditional financial systems. Real-world examples such as North Korea’s cryptocurrency thefts, Russia’s exploration of digital rubles, China’s use of the Digital Yuan for bilateral trade, and Iran’s state-sponsored cryptocurrency mining highlight the challenges that regulators face in curbing this behavior.
While international efforts are underway to close these loopholes, the rapid pace of technological innovation in the cryptocurrency space means that enforcement will continue to be a game of cat and mouse. Addressing the role of cryptocurrency in sanctions evasion will require not only robust international cooperation but also a rethinking of how sanctions are designed and enforced in a world increasingly dominated by digital assets.
