KEEN, no doubt, to stay alive, drug traffickers tend to be prompter payers than most. For software firms, this is just one of many clues that may hint at the laundering of ill-gotten money. Anti-money-laundering (AML) software, as it is called, monitors financial transactions and produces lists of the people most likely to be transferring the proceeds of crime.
Spending on this software is soaring. Celent, a research company, estimates that financial firms have spent roughly $825m on it so far this year, up from $675m last year. Technavio, another research firm, reckons the market is even bigger and will grow at more than 11% annually in coming years. This is partly because authorities are increasingly quick to punish institutions that let down their guard. Deutsche Bank, for example, has been hit with fines worth at least $827m this year alone. Governments, eager to appear tough on crime, are urging prosecutors to go after not just institutions, but also their employees.
