What is trade-based money laundering?

Quick answer

Trade-based money laundering (TBML) is the manipulation of international trade transactions to disguise and transfer criminal proceeds. The four main techniques are over-invoicing, under-invoicing, multiple invoicing, and misrepresentation of goods or services. FATF classifies TBML as one of three primary money-laundering methods worldwide.

The full answer

Trade-based money laundering (TBML) is the use of international trade transactions to disguise and move criminal proceeds. It's one of the three methods FATF identifies as central to global money laundering, alongside bulk cash smuggling and direct abuse of the financial system.

The core mechanic exploits a simple fact: the parties processing a trade transaction almost never see the actual goods. A bank issuing a letter of credit sees invoices and shipping documents. A customs broker sees manifests. Neither has an easy way to verify that the stated price reflects actual market value. That gap is what TBML exploits.

Over-invoicing is the most common technique. An exporter invoices above market price. The importer pays the inflated amount from a legitimate account. The excess flows to the exporter's country as what looks like a normal trade settlement.

Under-invoicing reverses the direction. Goods are invoiced below their actual value. The importer pays a discounted price using clean funds, takes delivery of goods worth more than stated, then resells at market rates. The profit on resale is laundered money converted to local currency.

Multiple invoicing generates multiple payments for the same shipment. Each payment looks like a separate commercial settlement, but the total paid exceeds the value of what was shipped.

False description of goods shifts value by misrepresenting what's being shipped: cheap goods billed as high-value items, or premium goods shipped against low-value invoices. The gap between reality and documentation is the laundered amount.

The Black Market Peso Exchange is the most extensively documented TBML case. Colombian trafficking organizations routed US drug proceeds through front companies to purchase consumer electronics and household goods. Those goods were exported to Colombia and sold at market prices. The pesos from those sales were clean commercial revenue with legitimate trade paperwork. The DEA and FinCEN documented this scheme in the early 2000s; variants of it operate across Latin America, Southeast Asia, and the Middle East to this day.

FATF's 2020 report on trade-based money laundering identified gold, diamonds, bulk electronics, and real estate as the highest-risk commodity categories for TBML. Pricing in those categories is opaque, highly variable, or both, which makes invoice benchmarking difficult.

Why this matters

Trade finance banks sit at the center of TBML exposure. The correspondent banking relationships that enable documentary trade also create layers between the bank and the underlying transaction. A bank in New York processing a trade finance payment between a Hong Kong exporter and a Lagos importer has limited ability to independently verify the commercial substance of the shipment.

FinCEN has been explicit: institutions must have TBML-specific typologies in their BSA/AML programs. Generic transaction monitoring built around domestic payment patterns catches very little TBML activity. Examiners look for evidence that staff can recognize TBML-specific red flags in trade documentation.

Key red flags to document in your typology library:

  • Invoice prices that deviate more than 20-30% from market benchmarks without a documented commercial explanation
  • Shipment routes that are geographically illogical (goods from China routed through Panama to reach Mexico)
  • Frequent amendments to letters of credit after issuance
  • Third-party payers with no documented relationship to the buyer or seller
  • Trade in commodities associated with TBML typologies: gold, bulk electronics, used vehicles, agricultural commodities
  • Counterparties in countries on the FATF Grey List

For customer due diligence purposes, trade finance customers in high-risk sectors require enhanced due diligence by default. That means verifying beneficial ownership down to the controlling individual, not just the corporate entity on the invoice. Shell companies are a consistent feature of TBML schemes.

When TBML is detected, SAR filing follows the standard timeline. There's no TBML-specific exemption to the 30-day window. FinCEN's definition of suspicious activity is broad enough to cover most TBML patterns, but examiners expect TBML-specific narrative language in the SAR: the specific invoice discrepancy, the commodity type, the corridor, the third-party payment structure. Generic "unusual transaction" language won't satisfy an examiner reviewing a TBML case.

AI-based transaction monitoring helps at the margin. Volumetric anomalies are easier to catch. The harder problem is that TBML often operates at entirely normal payment sizes, with the suspicious signal buried in documents that standard monitoring never reads. Better detection combines transaction analytics with automated commodity price benchmarking against databases like UN Comtrade and commercial pricing services such as Panjiva.

Alert false positive rates are particularly high for TBML detection because trade pricing variation is inherently wide. A 35% volume discount on a bulk electronics order can be normal procurement or an invoice manipulation scheme. Context, not the price gap alone, determines which it is.

Customer risk ratings for trade finance customers should be reviewed when there are changes in trade corridors, new counterparties in high-risk jurisdictions, or commodity mix shifts toward higher-risk categories. A customer who traded textiles last year and now trades gold through three new intermediaries warrants a fresh look.

  • What is the FATF Grey List? TBML risk concentrates heavily on trade corridors that pass through Grey List jurisdictions. Counterparty location is a primary screening criterion.
  • What is the difference between AML and CFT? TBML is primarily an AML concern. Some TBML schemes also finance terrorist organizations, making the practical distinction between AML and CFT controls blurry for trade finance teams.
  • What percentage of AML alerts are false positives? False positive rates for TBML detection are high because trade pricing variation is wide by nature. Reducing false positives requires commodity-specific benchmarks, not just transaction thresholds.
