A trafficking that adapts

Trafficking in cultural property is one of the most lucrative illicit trades, alongside drugs and arms according to several international organisations. It affects every continent: looting of sites, museum theft, smuggling, fakes, laundering.
The amounts are hard to establish because the phenomenon is clandestine. The OIMAP Observatory estimates, as an indication, that worldwide trafficking is worth between 3 and 6 billion euros a year.
The section presents an overview, a description of the networks and a summary of the annual reports.

A criminal chain
Trafficking follows a chain: looting or theft upstream, local intermediaries, carriers, receivers, unscrupulous dealers and, finally, buyers. At each link, provenance is blurred: false certificates, transit countries, successive sales.
Fighting trafficking means acting on each link: securing sites, controlling borders, training officers, making operators accountable and raising buyers' awareness. OIMAP works at each of these levels.



A trafficking linked to other offences
Trafficking in cultural property often overlaps with other offences: money laundering, tax fraud, corruption, financing of criminal organisations. Investigations conducted with INTERPOL and the WCO show that these networks use methods similar to those of other trafficking.
That is why the fight rests on cooperation between services: police, customs, justice, financial intelligence units. OIMAP's procedures are designed to fit with those of these administrations.
The role of the market
The lawful market is not the culprit, but it is the final outlet. It is what traffickers seek to reach in order to turn stolen property into money. Operators who apply due diligence close that door.
OIMAP therefore regards operators as partners: it provides them with the BIOP database, training and alerts, and expects in return that they report suspicious transactions and refuse doubtful provenances.

A phenomenon that moves



Repression or prevention

Repression
Investigations, seizures, prosecutions- Deters the networks
- Costly and long
- Downstream of the phenomenon
Necessary but insufficient.

Prevention
Securing, awareness-raising, diligence- Reduces supply and demand
- Less costly
- Acts upstream
OIMAP's priority.
Acting against trafficking
- Inform
Know the phenomenon.
- Prevent
Secure sites and collections.
- Detect
Consult the BIOP.
- Report
Alert the unit.
- Cooperate
Work with the services.

« Trafficking in cultural property is a crime without a cry. Nobody sees the works disappear, but it is a people's history being erased. »
