TL;DR: Brazil received an estimated $318 billion in on-chain value between July 2024 and June 2025, while illicit crypto value globally reached $154 billion in 2025 and over 50% of illicit flows into selected Brazilian exchanges came from three actor categories, according to Chainalysis. The regulatory question is no longer whether these flows exist, but whether Brazilian exchanges can operationalise detection and reporting fast enough to contain them.

By the numbers:
- 50% of illicit flows identified in selected Brazilian, Brazilian exchanges in 2025 came from three actor categories.
- The five most exposed deposit addresses accounted for between 75% and 90% of total illicit volume each quarter.
Questions worth separating out
Q: How should crypto compliance teams handle concentrated illicit flow patterns?
A: They should treat concentration as a prioritisation signal, not just a reporting metric.
Q: Why do stablecoins complicate financial crime monitoring?
A: Stablecoins move value quickly, hold price more predictably than volatile assets, and are easy to route across jurisdictions.
Q: How can organisations know if their crypto monitoring is working?
A: A useful sign is whether the programme can identify repeat high-risk clusters, explain why they are suspicious, and produce a consistent audit trail from alert to reporting.
Practitioner guidance
- Prioritise high-risk deposit clusters Group repeated deposit addresses by exposure and volatility, then route the highest-concentration clusters into enhanced review queues before they are allowed to disperse across downstream wallets.
- Unify KYC and on-chain monitoring Connect onboarding identity signals, sanctions screening, and wallet analytics so suspicious behaviour can be correlated across the customer lifecycle instead of reviewed as separate problems.
- Build regulator-ready evidence trails Ensure every alert can be reconstructed with source data, analyst decisioning, escalation history, and reporting outcomes so the control process survives supervisory challenge.

Illicit flow concentration is the real control problem, not raw market size. Brazil’s scale matters, but the more actionable signal is that a relatively small set of deposit addresses repeatedly absorbs most illicit value. That shifts the governance question from broad market surveillance to high-risk cluster identification and escalation discipline. For compliance teams, this is a case for prioritised interdiction rather than uniform scrutiny across all customers.
A question worth separating out:
Q: Who is accountable when illicit crypto flows pass through a regulated exchange?
A: Accountability sits with the exchange, its compliance leadership, and the supervisory regime that sets reporting and licensing obligations. Where customer identity, sanctions screening, and on-chain monitoring intersect, firms must prove that controls can detect, investigate, and report suspicious activity in a way regulators can verify.
