The Wolfsberg Group has published a report on a workshop jointly organized with the Basel Institute on Governance at the 2026 Global Conference on Criminal Finances and Cryptoassets. Participants emphasized that suspicious transaction and activity reports involving cryptoassets should be judged by their intelligence value, not their volume. The discussions focused on reporting quality, the use of blockchain analytics and cooperation, while leaving questions about historical transaction tracing unresolved.
Reporting should reflect professional judgment and genuine suspicion rather than alerts or red flags alone. Clear narratives should explain why activity is suspicious, what was reviewed and how the evidence supports the conclusion. Accurate identifiers, complete transaction details and structured data help financial intelligence units connect reports, including across borders. Blockchain analytics should support, not replace, human analysis and should be combined with customer due diligence and other evidence. Attribution can be incomplete, data quality varies and providers use different methods. Participants favored common standards for analytics governance, taxonomy and explainability.
Cooperation among banks, cryptoasset service providers and authorities can close information gaps within legal limits. Thematic guidance, typology publications and periodic quality feedback can help institutions improve reporting and reduce defensive filings. Participants agreed that tracing historical cryptoasset activity requires a proportionate approach but reached no common position on its practical scope. Questions also remain about how much information institutions can reasonably request from customers and whether reluctance to disclose wallet details for privacy or security reasons should itself be a risk indicator. The considerations remain subject to applicable legal and regulatory frameworks and reporting entities’ risk assessments.
