Illicit crypto flows surge to $158B

TLDR

Illicit cryptocurrency transactions are estimated to have reached about $158 billion in 2025, according to a new crime report from blockchain analytics firm TRM Labs.

1. TRM Labs pegs crypto crime volume at roughly $158 billion in 2025, up about 145% from 2024, even as it remains only around 1.2% of total on chain activity.
2. The spike is driven mainly by state linked sanctions evasion and professional laundering networks, especially a Russia associated ruble stablecoin called A7A5 and Chinese underground banking networks.
3. Expect tougher regulation on stablecoins, DeFi and cross border flows, but the data also supports the view that most crypto usage is still legitimate.

Deep Dive

1. What The $158B Covers

TRM Labs 2026 Crypto Crime Report estimates that crypto transactions linked to criminal activity reached about $158 billion in 2025, up from $64.5 billion in 2024, a jump of roughly 145 percent. Coverage from multiple outlets summarises the report as showing that this is the highest level in at least five years, reversing a prior downtrend in nominal crime volume.

However, TRM says this still represents only about 1.2 percent of total crypto transaction volume, slightly lower than 1.3 percent in 2024 and well below the 2.4 percent peak in 2023, meaning the legal crypto economy is growing faster than illicit use. Chainalysis arrives at a similar order of magnitude, estimating around $154 billion in criminal or money laundering related crypto flows, though methodologies differ.

2. Drivers Behind The Surge

The report and follow up coverage attribute much of the 2025 spike to sanctions evasion and state aligned activity, not retail scams. A Russia linked ecosystem centered on the A7 wallet cluster and the ruble pegged stablecoin A7A5 is reported to have processed over $70 billion in illicit stablecoin flows, with Russia focused sanctions evasion growing more than 400 percent year on year. Articles summarizing the TRM findings describe A7A5 as a key rail for moving value outside traditional banking for sanctioned entities.

Stablecoins generally dominate these flows. TRM estimates that about 95 percent of inflows to sanctioned entities and jurisdictions in 2025 used stablecoins, with a clear migration from regulated exchanges with strong KYC toward non custodial services and OTC brokers as compliance tightens. Separate research also highlights Chinese language laundering networks and underground banking operations processing over $100 billion in flows linked to scams and cybercrime.

3. Why It Matters For Users

Regulators and policymakers are already using figures like illicit crypto flows surge to record $158 billion as ammunition for stricter rules on stablecoins, DeFi front ends, and cross border transfers. Expect more intensive KYC, sanctions screening, and travel rule style requirements, especially for stablecoin issuers and liquidity venues.

At the same time, the fact that only about 1 to 2 percent of activity appears illicit supports the argument that most crypto usage is legitimate payments, trading, and saving. For ordinary users and builders, the practical impact is likely to be heavier compliance overhead rather than blanket bans, with more focus on high risk jurisdictions, bridges, OTC channels, and suspicious stablecoin ecosystems.

Conclusion

The $158 billion figure signals that crypto has become a meaningful rail for sanctions evasion and organized laundering, especially via niche stablecoins and underground networks. At the same time, the shrinking share of illicit volume relative to total activity suggests a maturing ecosystem, where most usage is lawful. For crypto participants, the key is to anticipate more targeted regulation and compliance around flows that resemble these high risk patterns, while recognising that the bulk of the market remains on the right side of the law.
