In a troubling development for the crypto industry, stablecoin transactions linked to illicit activities hit a staggering $141 billion in 2025, marking a five-year high, according to a new report from blockchain analytics firm TRM Labs. This surge, however, does not indicate a broader rise in crypto-enabled crime but highlights a growing reliance on stablecoins for specific types of illegal operations, particularly those involving sanctions evasion.
Stablecoins and Sanctions Evasion
The report underscores that 86% of all illicit crypto flows in 2025 were tied to sanctions-related activities. A significant portion of this, approximately $72 billion, involved the Russian ruble-pegged stablecoin A7A5, which is predominantly used within sanctions-linked networks. Russian-linked entities, such as the A7 network, are interconnected with other state-affiliated groups from China, Iran, North Korea, and Venezuela, highlighting how stablecoins have become a crucial infrastructure for sanctioned actors to circumvent traditional financial controls.
Illicit Marketplaces and Human Trafficking
TRM Labs also noted a concerning trend in the use of stablecoins for illicit goods and services, particularly human trafficking. Guarantee marketplaces like Huione, which saw a surge in volume to over $17 billion by late 2025, predominantly used stablecoins. This suggests that these platforms prioritize payment certainty and liquidity over the volatility associated with other cryptocurrencies.
Chainalysis, another blockchain analytics firm, reported that crypto flows to suspected human trafficking networks increased by 85% year-over-year in 2025. These networks, including international escort services and prostitution rings, operate almost exclusively using stablecoins, further emphasizing the role of stablecoins in facilitating illicit activities.
Stablecoin Usage in Other Illicit Activities
While scams, ransomware, and hacking activities also utilize stablecoins, they tend to favor Bitcoin (BTC) or other crypto assets for initial transactions before switching to stablecoins later in the laundering process. This selective use highlights the different operational needs and risk profiles of various types of illicit actors.
Broader Implications and Regulatory Challenges
The total stablecoin transaction volume exceeded $1 trillion on multiple occasions in 2025, suggesting a significant portion of the $12 trillion in annual stablecoin transactions is legitimate. However, the 1% of transactions linked to illicit activities, amounting to $141 billion, is a cause for concern. Compared to the United Nations estimate that 2% to 5% of global GDP, or around $800 billion to $2 trillion, is laundered annually, the stablecoin issue is a smaller but growing segment of the broader problem.
Regulators and law enforcement agencies face an increasingly complex challenge as stablecoins continue to evolve and find new applications. The decentralized and borderless nature of these digital assets makes it difficult to track and prevent their misuse, particularly in jurisdictions with lax regulatory frameworks.
Looking Ahead
As the crypto industry matures, the need for robust regulatory frameworks to combat illicit activities becomes more urgent. The findings from TRM Labs and Chainalysis highlight the importance of international cooperation and the development of advanced monitoring tools to detect and disrupt illicit stablecoin transactions. The future of stablecoins and their role in the global financial system will depend on how effectively these challenges are addressed.
