A key feature of the international financial system over at least the last decades has been the large expansion of cross-border financial transactions. This expansion is very noticeable in border regions since people and businesses at both sides of the border try to benefit from advantages on one side or the other. Cross-border transactions have grown significantly and US northern and southern borders are no exception. .
All types of Criminals – and terrorists too, around the world are also very active in the border regions; they use cash couriers as a major means of physically moving funds across borders in order to finance their illicit activities and to launder their ill-gotten gains. There have been many initiatives to facilitate the detection, investigation and prosecution of drug trafficking offences and serious crimes that involve the transportation of cash across borders; international anti-money laundering and counter-financing of terrorism standards recommended by the Financial Action Task Force (FATF) are in place in most countries and this Best Practice Paper describe such standards. Another good Best Practice Paper was issue by the MENA FATF group.
