Governments and organizations under international sanctions moved roughly $104 billion through cryptocurrency in 2025, a nearly sevenfold increase that made sanctions evasion the single largest driver of illicit digital-asset activity, according to the 2026 Crypto Crime Report published by blockchain analytics firm Chainalysis. The firm found that total illicit crypto flows reached approximately $154 billion for the year, up 162% from 2024, with the surge driven overwhelmingly by state and state-linked actors seeking to maintain access to global markets despite Western sanctions.

The report, released earlier this year and reinforced by a parallel study from analytics firm TRM Labs, points to a structural shift rather than a one-time spike. Chainalysis concluded that cryptocurrency is no longer a fringe workaround for sanctioned governments but has become a core component of their financial infrastructure, supporting international trade settlements, weapons procurement and cross-border money transfers. Roughly 84% of illicit transaction volume flowed through stablecoins—digital tokens pegged to traditional currencies and valued for maintaining price stability while funds move across borders.

Russia sits at the center of the findings. Chainalysis identified a ruble-backed stablecoin known as A7A5, which processed approximately $93.3 billion in transactions in less than one year, effectively serving as a settlement network for sanctioned Russian businesses. The activity was linked to the cryptocurrency exchange Garantex and its successor, Grinex—entities that the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) has sanctioned alongside a Kyrgyz-issued token and a network of associated companies. According to the report, when one exchange is shut down, operators increasingly establish a replacement. Grinex was created by former Garantex personnel after law enforcement action disrupted the original platform.

Iran’s use of cryptocurrency appears more operational. The report found that networks associated with the Islamic Revolutionary Guard Corps (IRGC) accounted for more than half the value flowing into Iranian cryptocurrency services during the second half of 2025, with total transfers reaching approximately $3 billion. The funds were used to support regional proxy groups while facilitating arms and oil transactions. North Korea experienced its largest cryptocurrency theft year on record, stealing more than $2 billion, including approximately $1.5 billion during a single cyberattack against the Bybit exchange—the largest crypto theft reported to date. Investigators concluded that the proceeds helped finance the regime’s weapons programs.

For the broader cryptocurrency industry, the findings present two competing narratives. Supporters point out that illicit transactions still represent less than 1% of total cryptocurrency activity and argue that public blockchains are inherently transparent, allowing investigators to trace transactions in ways impossible with cash. That transparency has fueled demand for compliance software from firms such as Chainalysis and TRM Labs, which now sell blockchain monitoring tools to governments, banks and digital-asset exchanges.

The headline figures nevertheless present a significant challenge for an industry still working toward mainstream financial acceptance. A $104 billion sanctions-evasion network is precisely the type of statistic that strengthens the resolve of regulators and makes traditional financial institutions more cautious about working with cryptocurrency firms. It raises compliance expectations—and compliance costs—for legitimate exchanges and stablecoin issuers, which increasingly face pressure to identify sanctioned wallets, monitor transactions and freeze suspicious assets or risk losing access to the traditional banking system. Enforcement has likewise evolved, with OFAC, the European Union, and the United Kingdom’s sanctions authorities increasingly identifying specific cryptocurrency wallet addresses directly in their sanctions lists.

The role of stablecoins deserves particular attention from the business community. As dollar-backed digital tokens move closer to mainstream financial adoption, the report’s conclusion that stablecoins now carry the majority of illicit transaction volume places issuers in a difficult position. Their future growth depends on being viewed as safe, regulated financial products closely connected to the banking system, yet those same characteristics also make them attractive tools for sanctioned governments seeking efficient cross-border payments.

The findings also arrive against an active geopolitical backdrop. With global energy markets already under pressure from conflict involving Iran, the report’s conclusion that Tehran increasingly relies on cryptocurrency to move oil revenue and finance regional proxy groups underscores how digital assets have become an important pressure valve for governments facing international sanctions. For banks, exchanges and payment companies, the message is increasingly clear: the primary illicit-finance risk surrounding cryptocurrency is no longer dominated by scams and ransomware attacks. It is increasingly driven by nation-states—and measured in the tens of billions of dollars.
