There is also SAD money, Secured and Delivered, which has to do with money secured with tangible goods.
oh yeah, the chinese have that one down pat, most recently with iron ore. get a loan, secured with a shipment of iron ore held in port. then another loan, secured with the same ore. it's easy, just walk the loan officer down to the port, show them the ore and the paperwork proving it's yours, it's all right there in front of you, it's all legitimate, what could go wrong, get the loan. then another, then another, then another. a recent case in the news related how one chinese businessman did this something like 50 times over, and then on top of that turned around and sold the ore itself, AFTER returning the ore and getting his original money back. and then disappeared, leaving lots of people real SaD.
gotta watch out for that "secured" thing ....
