Money laundering is not a problem confined to national borders. Criminal proceeds flow seamlessly across international financial systems, making it impossible for any single country to combat the threat alone. For decades, the United States has partnered with foreign governments through a network of international treaties and agreements that form the backbone of modern anti-money laundering (AML) enforcement.

 The Framework: Key International Treaties

 The United Nations Convention Against Transnational Organized Crime (the Palermo Convention) and the UN Convention Against Corruption (UNCAC) are two cornerstone agreements that obligate signatory nations, including the U.S., to criminalize money laundering and cooperate in investigations and prosecutions. Separately, the Financial Action Task Force (FATF), an intergovernmental body, establishes global AML standards that member countries are expected to adopt and enforce.

 These frameworks are not merely aspirational. They directly shape U.S. domestic law, including the Bank Secrecy Act (BSA), the Money Laundering Control Act, and the anti-money laundering provisions embedded in the USA PATRIOT Act.

How Treaties Influence U.S. Enforcement

One of the most practical tools arising from these treaties is the Mutual Legal Assistance Treaty (MLAT). MLATs allow U.S. prosecutors to formally request evidence, bank records, and witness testimony from foreign governments, and vice versa. When federal authorities investigate a complex money laundering scheme involving offshore accounts or foreign shell companies, MLATs are often the mechanism that enables them to pierce corporate veils across jurisdictions.

Extradition treaties further reinforce enforcement by ensuring that individuals who launder money abroad cannot simply flee to avoid U.S. prosecution. Combined with asset forfeiture cooperation agreements, these tools give federal prosecutors substantial cross-border reach.

What This Means for the Accused

For individuals and businesses facing federal money laundering charges, the international dimension of modern AML enforcement is critically important. Evidence gathered through foreign governments, financial intelligence shared under FATF protocols, and foreign witnesses secured via MLAT requests can all play decisive roles in a federal prosecution. An effective defense must account for this global evidentiary landscape – including challenging how evidence was obtained abroad and whether applicable treaty procedures were properly followed.
