What is trade-based money laundering?

The full answer

Trade-based money laundering is the use of international trade to transfer and disguise criminal proceeds. It's one of the oldest laundering methods and, per FATF's own assessment, one of the least disrupted.

The four core techniques are well-documented:

• Over-invoicing: The exporter bills above market value. The buyer transfers the surplus, moving money to the seller's jurisdiction under cover of a commercial invoice.
• Under-invoicing: Goods travel below their declared value. Physical goods carry the value rather than cash. Common in jurisdictions with capital controls where moving dollars out directly would be blocked.
• Multiple invoicing: One shipment generates separate invoices to multiple financial institutions. Each payment is individually defensible; combined, they represent fraud against the trade finance system.
• Phantom shipments: Legitimate-looking trade documents are created for goods that do not exist or are entirely different from what is described. The financial transaction is real; the commercial basis is not.

The Black Market Peso Exchange ties these techniques into a complete system. Drug dollars in the US buy consumer goods from US exporters. Those goods ship to Colombia and sell in local markets for pesos. The cartels receive domestic currency without ever physically moving cash across a border. FATF formally documented this mechanism in its 2006 TBML report, and the scheme, in various forms, remains in use today.

TBML isn't only a Latin American narco-finance problem. FATF's 2020 follow-up report linked the method to fraud, tax evasion, and proliferation finance in Asia, the Middle East, and Eastern Europe. Any jurisdiction where goods pricing is hard to benchmark creates an opportunity.

Why this matters

TBML is the part of AML that most compliance programs handle worst.

Transaction monitoring systems are built for the financial leg: payment amounts, counterparty names, account velocity. They don't ingest shipping manifests, commodity price feeds, or Harmonized System (HS) codes. A $3 million payment for "machine parts" from a trading company in a high-risk jurisdiction looks, to a standard monitoring system, like a single transaction. It might be six phantom invoices from the same shell company.

The gap is structural. Banks see payments. Customs sees freight. Freight forwarders see physical goods. The Wolfsberg Group's Trade Finance Principles (2019) address this directly: risk-based due diligence on trade transactions requires understanding the commercial purpose, not just the payment mechanics.

Bank examiners have made trade finance a distinct focus area. Programs now face specific scrutiny on whether customer due diligence and EDD protocols account for trade-specific risk factors, not just general counterparty risk. A corporate customer's trade finance book should carry its own risk assessment, separate from the broader relationship profile.

The SAR filing obligation applies to TBML indicators. Anomalous pricing, circular trade patterns, counterparties in FATF grey list jurisdictions, and mismatches between declared goods and shipped goods all fall within FinCEN's definition of suspicious activity. Regulators have cited TBML under-reporting as a systemic problem. Examiners are specifically looking for it.

Knowing who the beneficial owner is behind trade finance counterparties is the starting point for any TBML risk assessment. Shell companies and trading intermediaries are common in legitimate trade finance. They're also the standard TBML vehicle. Customer risk rating reviews for trade customers need to account for jurisdiction, goods type, and counterparty ownership structure, not just transaction volume.

AI-based transaction monitoring is one of the more practical tools available for this problem. Models trained on commodity pricing data can flag invoices outside market price ranges for the goods described. Network analysis connects the same beneficial owner across multiple trade relationships where manual review would miss the link. Trade finance alert volumes are high, and what percentage of AML alerts turn out to be false positives is a live operational question for teams running these programs.

For banks where TBML surfaces in a regulatory exam, the institutional consequences are serious. What triggers a regulatory exam? includes unusual SAR patterns, adverse correspondent banking relationships, and trade finance complaints. Banks with systemic AML failures have faced consent orders, deferred prosecution agreements, and in some cases court-appointed monitorships.
