Transaction monitoring watches payments. Trade-based laundering hides in the documents.

Issue #9 | June 24, 2026 | 7 min read

Trade-based money laundering is one of the three principal methods of criminal money laundering identified by FATF, alongside cash placement and wire transfer schemes. It runs through letters of credit, invoices, shipping documents, and commodity payments. which are the infrastructure of legitimate international commerce.

It's also the category least represented in U.S. enforcement actions. Not because it's rare, but because the standard AML program architecture doesn't produce the SAR trail that leads to a FinCEN penalty.

This issue covers how TBML works, what the common typologies look like in practice, why transaction monitoring misses most of it, and what an operational program would need to actually catch it.

PRACTITIONER INTELLIGENCE

FATF has identified trade-based money laundering as one of the three main methods used globally. The enforcement record doesn't reflect that. Here's why.

The basic mechanics of TBML are well-documented. FinCEN's advisory on the topic (FIN-2010-A001) and FATF's typology reports identify four primary methods: over- or under-invoicing goods and services, multiple invoicing for the same shipment, falsely described goods (quantity or type), and phantom shipments (payment for goods that were never shipped). The common thread is that illegal value is transferred not through a wire payment but through the manipulation of trade documentation, using a real commercial transaction as cover.

What makes this practically difficult to catch is that each individual transaction looks like exactly what it is: a payment under a letter of credit, a documentary collection, a wire in settlement of an invoice. A $500,000 payment for a shipment of agricultural commodities doesn't generate a transaction monitoring alert. Neither does a payment that's 30% above the market price for that commodity, because the TM system doesn't know what the market price is.

What transaction monitoring catches, and what it doesn't

Transaction monitoring systems are built for behavioral anomalies in payment flows: structuring patterns, velocity changes, unusual counterparties, sanctions hits, high-risk geography in wire transfers. These are real risk indicators. They're also poorly suited to TBML.

TBML doesn't produce structuring patterns. It produces normal-volume, normal-frequency payments for international trade. It doesn't involve unusual counterparties the way a shell company wire does, the counterparty is a real trading company. The payment amount isn't anomalous on its own. The anomaly is in the ratio between the invoice price and the market price, which exists in the shipping document, not in the payment record.

Most transaction monitoring systems don't ingest trade documentation. Letters of credit, bills of lading, commercial invoices, certificates of origin, these are processed by trade finance teams, not fed into the TM platform. The practical result is that TBML can move through a bank's trade finance operation in one lane while the AML function monitors transactions in a separate lane with no visibility into the documents behind them.

The three typologies worth understanding operationally

Over/under-invoicing is the most common TBML method. An exporter invoices an importer at a price above or below market value for the goods, and the difference represents value transferred between parties outside the formal financial system. A Colombian commodity exporter invoicing a U.S. importer at 40% above the benchmark price for coffee isn't moving money through a bank, the bank is the settlement mechanism. The value transfer happens in the document.

Multiple invoicing involves billing for the same shipment more than once. Two or more banks may each finance the same underlying goods if they can't verify that another institution has already extended credit against the same documentation. In trade finance this is known as duplicate financing fraud, but the proceeds serve a laundering purpose when the parties involved intend them to.

Phantom shipments are payments for goods that were never shipped or don't exist. The supporting documentation, commercial invoice, bill of lading, packing list, is fabricated. The payment is real. This sometimes surfaces through customs irregularities, but customs data isn't something most banks cross-reference against trade finance activity.

What actually catches it

Institutions with meaningful TBML detection capability generally have three things in place that most programs don't.

The first is commodity price benchmarking; some mechanism for comparing invoice values against market prices for commonly traded goods. This doesn't need to be sophisticated. For institutions with concentrated trade finance exposure in specific commodities or corridors, knowing the typical price range for those goods is operational knowledge, not an exotic capability. The question is whether anyone in the review process is asking whether the invoice price makes sense.

The second is trade finance and AML integration. Trade finance relationship managers and compliance staff often operate in separate workflows with no clear channel between them. Unusual shipping routes, shell company importers, dual-use goods, discrepancies between the described goods and the countries involved, trade finance staff notice these things. They rarely have a defined path to the SAR process.

The third is corridor-based risk. TBML flows heavily through specific trade corridors: South America to the United States, China to Latin America, Middle East to Europe. An institution with concentrated exposure in those corridors that isn't applying heightened documentary scrutiny to those accounts hasn't made a risk-based decision. It's made an operational decision that looks like one.

The practitioner question

FinCEN's advisory on TBML is from 2010. FATF's foundational typologies report on the subject is from 2006. The guidance hasn't changed because the methods haven't changed, they work. What has changed is the volume of international trade running through the same channels, and the complexity of commodity financing structures sitting on top of it.

Most compliance programs have a TBML policy. It says the institution will monitor for indicators of trade-based money laundering. What it rarely specifies is how. What mechanism flags an over-invoiced letter of credit? Who in the compliance function reviews trade documentation? How does the trade finance team escalate a phantom shipment concern into the SAR process?

If the answer is "the TM system would catch it," the program has a gap. Transaction monitoring watches payments. TBML hides in the documents that payments settle.

INTELLIGENCE BRIEFING

FinCEN — In May 2026, FinCEN issued a notice urging financial institutions in and around 2026 FIFA World Cup host cities to increase vigilance for human trafficking-related suspicious activity during the tournament, which runs June 11 through July 19. The eleven U.S. host cities — Atlanta, Boston, Dallas, Houston, Kansas City, Los Angeles, Miami, New York/New Jersey, Philadelphia, San Francisco Bay Area, and Seattle — are the primary focus. FinCEN is asking institutions to file SARs on suspected trafficking-related activity as soon as possible regardless of threshold, and to notify law enforcement through the National Human Trafficking Hotline. For institutions in those markets, this is an active obligation through mid-July. Source: FinCEN Notice, "Threat of Human Trafficking During the 2026 FIFA World Cup," May 2026.

FinCEN — On June 22, FinCEN published a proposed Customer Identification Program rule for permitted payment stablecoin issuers in the Federal Register. This follows the April 2026 AML/CFT program NPRM for stablecoin issuers, whose comment period closed June 9. The CIP proposal would apply customer identification requirements that mirror existing bank CIP obligations. Comments are due August 21, 2026. The practical implication: the regulatory perimeter for stablecoin issuers is expanding on two simultaneous tracks, AML/CFT programs and CIP, with the GENIUS Act framework moving toward enforcement reality.

OFAC — On June 18, OFAC designated Hizballah-aligned Lebanese officials and an associated business network overseen by Alaa Hassan Hamieh, targeting front companies and interlocutors operating across Lebanon, Syria, Iraq, and Oman. The action expands March 2026 designations and focuses on the revenue-generating and contract-execution layer of Hizballah's financial infrastructure. For institutions with correspondent relationships or payment exposure in those jurisdictions, the June 18 SDN updates are live and screening queues should reflect the new entries.

FROM THE SOURCE

Sixteen years since that advisory. The methods it describes are still in use. The enforcement record on TBML, compared to cash structuring or SAR non-filing, reflects how hard it is to catch, not how rarely it happens. A bank that has never filed a SAR citing TBML indicators hasn't necessarily avoided the exposure. It may have avoided the scrutiny that would make the exposure visible.
