There are three main methods by which criminal organisations and terrorist financiers move money for the purpose of disguising its origins and integrating it into the formal economy. The first is through the use of the financial system; the second involves the physical movement of money (e.g. through the use of cash couriers); the third is through the physical movement of goods through the trade system. In recent years, the Financial Action Task Force has focused considerable attention on the first two of these methods. By comparison, the scope for abuse of the international trade system has received relatively little attention.
The international trade system is clearly subject to a wide range of risks and vulnerabilities that can be exploited by criminal organisations and terrorist financiers. In part, these arise from the enormous volume of trade flows, which obscures individual transactions; the complexities associated with the use of multiple foreign exchange transactions and diverse trade financing arrangements; the commingling of legitimate and illicit funds; and the limited resources that most customs agencies have available to detect suspicious trade transactions.
Trade-based money laundering is defined as the process of disguising the proceeds of crime and moving value through the use of trade transactions in an attempt to legitimise their illicit origins. In practice, this can be achieved through the misrepresentation of the price, quantity or quality of imports or exports. Moreover, trade-based money laundering techniques vary in complexity and are frequently used in combination with other money laundering techniques to further obscure the money trail.
