Crypto Crime Hits $154B in 2025 but It’s Below 1% of Onchain Activity

Illicit crypto transactions surged to record levels in 2025, yet the digital asset economy continues expanding as legitimate adoption accelerates worldwide, highlighting a rapidly growing blockchain ecosystem that still overwhelmingly operates within legal activity.

Illicit Crypto Flows Surge While Global Adoption Accelerates

Despite the rise in illicit activity, the broader cryptocurrency ecosystem continues to expand rapidly as adoption accelerates across global markets. Blockchain analytics firm Chainalysis published its 2026 Crypto Crime Report on March 5, outlining record illicit transaction volumes alongside continued growth in legitimate crypto usage.

The report details the sharp rise in illicit cryptocurrency flows over the past year, stating:

“According to our data, illicit cryptocurrency addresses received at least $154 billion in 2025. This represents a 162% increase year-over-year (YoY), primarily driven by a dramatic 694% increase in the value received by sanctioned entities.”

The analysis emphasizes that the estimate represents a lower-bound calculation based on addresses currently identified as illicit. Researchers also point out that sanctioned entities, including those linked to geopolitical conflicts and state-backed financial networks, contributed significantly to the surge in activity.

Despite the growth in illicit value, the study underscores that the broader crypto ecosystem remains overwhelmingly legitimate. Researchers clarify that illicit activity represents only a small fraction of total blockchain usage. The report states:

“These illicit volumes are still dwarfed by the broader crypto economy, which largely consists of legitimate transaction volumes. Our estimate for the illicit share of all attributed crypto transaction volume increased slightly from 2024 but remains below 1%.”

The report also identifies a structural shift in the types of digital assets used for criminal activity. “For the past few years, stablecoins have come to dominate the landscape of illicit transactions, and now account for 84% of all illicit transaction volume,” it notes. Analysts attribute the trend to the advantages stablecoins offer, including lower volatility, easy cross-border transfers, and high liquidity across global markets.

Beyond documenting crime trends, the report also addresses the broader financial role of blockchain infrastructure. The research suggests that digital assets could support economic recovery and financial access in regions facing financial instability or limited banking services.

Researchers emphasize that blockchain transparency continues to provide investigators and regulators with powerful tools to trace illicit flows while enabling legitimate innovation across the digital asset sector, concluding:

“If coupled with sound regulation and inclusive policy frameworks, these tools could help governments leverage crypto not just for resilience, but also for broader financial inclusion as part of economic recovery.”
