Background

Customer

Your objective
Determine whether the exposure is genuine sanctions and mixer risk, and decide on reporting, account restriction and the licence-critical escalation.
Initial concern
In sixty days, 31 percent of inbound value has one-hop exposure to a mixer and 4 percent traces to an OFAC-designated address cluster, while Travel Rule data on outbound transfers is systematically incomplete.
