According to a new report from blockchain analytics firm Chainalysis, illicit cryptocurrency transaction volume reached a staggering $154 billion in 2025, a near-tripling from the $59 billion recorded in 2024. This figure represents a dramatic, non-linear jump that far exceeds previous years, where volumes were $11 billion (2020), $29 billion (2021), $56 billion (2022), and $50 billion (2023).
The surge is not attributable to overall market growth alone. Chainalysis characterizes the trend as crypto crime becoming "industrialized," indicating a shift from opportunistic individual actors to organized, professionalized criminal enterprises with sophisticated infrastructure.
The primary driver of the increase was sanctions evasion, with funds sent to sanctioned entities skyrocketing by 694% year-over-year to approximately $104 billion. This points to a structural shift where nation-states like Russia, Iran, and North Korea are actively building financial infrastructure around cryptocurrency to circumvent traditional financial sanctions. A notable example is Russia's launch of the A7A5 ruble-pegged stablecoin, which processed over $93 billion before facing sanctions from the U.S. and EU.
Other criminal categories also contributed to the total. Stolen funds from hacks exceeded $2 billion, with North Korean-linked hackers responsible for the bulk, including a record-breaking $1.5 billion breach of the Bybit exchange in February 2025. Scams, ransomware, darknet markets, and terrorist financing all added to the illicit volume.
The report highlights a shift in the tools and methods used by criminals. Stablecoins now dominate illicit flows, accounting for 84% of all illicit transaction volume, while Bitcoin's share has fallen to just 7%. Furthermore, criminal operations have professionalized, with Chinese money laundering networks offering "laundering-as-a-service" and phishing scams leveraging AI tools, leading to a 1,400% year-over-year growth in that category. Physical "wrench attacks" to coerce wallet access also nearly doubled.
Despite the alarming absolute numbers, Chainalysis notes that illicit activity still represents less than 1% of total cryptocurrency transaction volume, which runs into the tens of trillions. However, the firm warns that the sheer scale of the $154 billion figure and the rapid movement of funds—often within 48 hours—demands more proactive compliance and law enforcement responses. The data is expected to intensify regulatory scrutiny, particularly on stablecoins and custody practices.
