The use of numbered accounts (outlawed in Austria, for instance, only recently) and pseudonyms (still possible in Lichtenstein) complicates matters. Bin Laden's accounts are unlikely to bear his name. He has collaborators. Hawala networks are often used to launder money, or to evade taxes. Even when employed for legitimate purposes, to diversify the risk involved in the transfer of large sums, Hawaladars apply techniques borrowed from money laundering. Deposits are fragmented and wired to hundreds of banks the world over ("starburst"). Sometimes, the money ends up in the account of origin ("boomerang"). Hence the focus on payment clearing and settlement systems. Most countries have only one such system, the repository of data regarding all banking (and most non-banking) transactions in the country. Yet, even this is a partial solution. Most national systems maintain records for 6-12 months, private settlement and clearing systems for even less. Yet, the crux of the problem is not the Hawala or the Hawaladars. The corrupt and inept governments of Asia are to blame for not regulating their banking systems, for over-regulating everything else, for not fostering competition, for throwing public money at bad debts and at worse borrowers, for over-taxing, for robbing people of their life savings through capital controls, for tearing at the delicate fabric of trust between customer and bank (Pakistan, for instance, froze all foreign exchange accounts two years ago). Perhaps if Asia had reasonably expedient, reasonably priced, reasonably regulated, user-friendly banks - Osama bin Laden would have found it impossible to finance his mischief so invisibly.
