This document discusses the high costs that financial institutions face in complying with anti-money laundering (AML) regulations and whether these expenditures are optimally utilized. It notes that while AML compliance costs have doubled or more for many institutions since 2001, numerous enforcement actions have still been taken against banks for deficiencies in areas like staff training and expertise. The document suggests that rather than simply increasing budgets, institutions need to ensure training programs are well-designed and provide ongoing support and guidance to staff, in order to maximize the return on their AML compliance expenditures.
