On 23 October 2020, OLAF reported on the results of the joint customs operation Daphne that tackled illicit cross-border cash flows. The one-week operation took place in late 2019. It was led by the Italian Customs and Monopolies Agency and OLAF and involved 24 EU Member States. The operation identified €17 million in illicit cash flows.

Customs authorities detected a total of 508 cases of undeclared and opaque cash flows, leading to around 40 follow-up investigations. The vast majority of cases (423) involved air traffic, accounting for €15 million. Most of the cases (453) concerned passengers travelling to/from outside the EU (total of €15.6 million). Passengers travelling to/from EU countries accounted only for 31 cases. OLAF mainly supported through its Virtual Operations Coordination Unit, which enabled the secure exchange of information during the operation.
