Anti-Money Laundering: U.S. Efforts to Combat Narcotics-Related Money Laundering in the Western Hemisphere, Report to the Ranking Member, Committee on Foreign Affairs, House of Representatives [open pdf - 3MB]
From the Document: "Proceeds from narcotics-related illicit activities are one of the most common sources of money laundering in the United States. Though difficult to accurately determine, in 2015, Treasury estimated that drug trafficking generated about $64 billion annually from U.S. sales. Moreover, the Western Hemisphere accounts for about a third of the jurisdictions designated by State as of primary concern for money laundering. GAO [Government Accountability Office] was asked to provide information on U.S. efforts to impede illicit proceeds from drug trafficking from entering the financial systems of the United States and other Western Hemisphere countries. This report describes (1) U.S. agency oversight and monitoring of compliance with the BSA [Bank Secrecy Act], including collaboration with counterparts in other Western Hemisphere countries, and (2) State's and Treasury's efforts to build capacity in other Western Hemisphere countries to combat narcotics-related money laundering. GAO reviewed laws and regulations; interviewed experts and U.S. officials; reviewed documents and examined State's and Treasury's budget data for fiscal years 2011 through 2015, the most recent at the time of the review, for anti-money laundering activities. GAO selected Colombia, Mexico, and Panama--three principal recipients of AML [anti-money laundering] support--for site visits, in part, because each country was designated a major drug transit or illicit drug-producing country from fiscal years 2014 through 2016."
