Understanding Money Laundering Defense in the Digital and Trade-Based Economy

By John D. Kirby, Former U.S. Federal Prosecutor ·

The landscape of money laundering defense has become increasingly complex with the advent of cryptocurrencies and sophisticated trade-based techniques. This article delves into the intricacies of defending against charges under 18 U.S.C. § 1956 (money laundering) and § 1957 (property transactions involving criminally derived property), focusing on how these statutes apply to both traditional banking activities and modern digital currency schemes.

Trade-Based Money Laundering

One sophisticated method of money laundering involves trade-based activities, where illicit funds are moved through the international trade system using false documentation. This can include over- or under-invoicing of commodities to mask illegal proceeds. For example, a company might manipulate customs forms by declaring different values than those on commercial invoices, thereby concealing true ownership and value.

Law enforcement agencies such as the FBI Financial Crimes Section, DEA Financial Investigations Unit, IRS-Criminal Investigation Division, and FinCEN collaborate closely to identify suspicious patterns indicative of trade-based money laundering. They look for discrepancies in declared values compared with real market prices or unusual trading partners that do not align with a company's typical business practices.

Cryptocurrency and Money Laundering

The anonymity and decentralization of blockchain technology have made cryptocurrencies an attractive tool for money launderers. Under 18 U.S.C. § 1956, transferring value using cryptocurrency exchanges with the intent to conceal illicit activities can be considered money laundering. Prosecutors often use transaction patterns, IP addresses linked to suspicious accounts, and communication records to build their case.

Defense attorneys must understand both the technical aspects of digital currencies and traditional legal principles. Analysis of blockchain forensics is crucial for uncovering the true nature of alleged illicit activities and challenging prosecution claims. Moreover, identifying regulatory violations can be a key point of contention in federal prosecutions involving cryptocurrencies.

Mitigating Factors in Sentencing

When facing money laundering charges under statutes such as 18 USC § 1956 or § 1957, the potential for severe sentencing looms large. Statutory penalties can range from fines to imprisonment based on the nature and extent of the offense.

A critical aspect in defending clients accused of money laundering is challenging the admissibility of evidence presented by agencies like FinCEN and the IRS-Criminal Investigation Division (IRS-CI). This involves recognizing whether transactions were structured to evade reporting requirements under 31 USC § 5324 or if they involved unlicensed money transmitting businesses covered by 18 U.S.C. § 1960.

Recent Prosecutorial Focus: Structuring and Integration

The federal government's recent prosecutorial focus has expanded to include routine business cash-management practices under the "structuring" element of money laundering, as defined in 18 U.S.C. § 1956(a)(1)(B)(i). This interpretation now captures ordinary business conduct that historically fell below the radar of federal enforcement.

The July 2024 update to the Department of Justice’s Money Laundering and Asset Recovery Section internal guidelines instructs prosecutors to pursue cases where a defendant makes multiple deposits just under the $10,000 reporting threshold. In my experience as a former federal prosecutor, this approach fundamentally inverts the burden of proof by focusing on the method of deposit rather than the source of funds.

The Eleventh Circuit’s decision in United States v. Perez (2023) clarified that mere structuring without additional evidence of concealment is insufficient to sustain a conviction under § 1956(a)(1)(B)(i). This decision highlights the importance for defense attorneys to challenge the sufficiency of evidence linking structured deposits to specified unlawful activity.

Checklist

The evolving legal landscape requires a nuanced approach to money laundering defense, particularly in integrating traditional financial crime statutes with modern digital and trade-based techniques. Understanding these nuances is crucial for crafting robust defenses that challenge the government's case while adhering to established legal principles.

New Developments in Money Laundering Cases

According to United States v. Perez and subsequent rulings, mere structuring transactions to evade reporting requirements does not necessarily constitute money laundering under 18 U.S.C. § 1956 or § 1957.

The recent cases of United States v. Santos and United States v. Rissman have further clarified the government's burden in proving money laundering charges, establishing stricter standards for prosecution. These rulings reflect a trend towards limiting expansive interpretations of money laundering statutes.

The analysis of cases from 2022 onwards indicates an increasing judicial scrutiny on the types of evidence required for conviction under money laundering statutes, diverging from previous years such as 1956 and 1957 when regulations were less stringent. This shift is evident in state-level courts as well, aligning with national trends towards stricter evidentiary requirements.
