Financial supervisors in three jurisdictions have begun coordinated examinations of crypto brokers' compliance with transfer information requirements, according to firms that received the requests.

Examiners are asking for transaction-level evidence that counterparty data accompanied transfers in real time, a stricter reading than the retrospective record-keeping many firms built.

Compliance heads say the hardest cases involve transfers to self-hosted wallets, where there is no institution on the other side to exchange data with.

Two vendors that operate shared messaging networks reported a jump in onboarding enquiries since the examinations began.

Penalties are not expected immediately. Supervisors have described this round as fact-finding intended to inform a common interpretation before enforcement begins.
