It was apparent from the questionnaire responses that this phenomenon of legitimate cross-border
cash transportation was not well understood generally. In the questionnaire, countries were asked
to state which methods, in their experience, were most frequently used to transport legitimate
consignments of cash across their borders. A summary of the responses are shown in the chart
below. The responses showed that most countries were aware that air passengers and persons in
cars carry cash legitimately across borders. However, substantially fewer had any experience of
cash moving in cargo and mail for legitimate purposes, and yet huge amounts of cash (the equivalent
of tens, and sometimes hundreds of millions of US dollars in a single shipment) are transported
between major financial institutions by air cargo every day, shipments that are generally subject to
very little scrutiny by customs authorities.
