What is Trade-Based Money Laundering?

Last updated: 26 October 2026

What Is Trade-Based Money Laundering (TBML)?

Trade-based money laundering (TBML) is the process of disguising the proceeds of crime and moving value through trade transactions, in an attempt to make their illicit origins look legitimate. Instead of moving cash through accounts, criminals misrepresent the price, quantity or quality of goods, or invent trade that never happened, so that value moves across borders under cover of ordinary commerce. It is one of the hardest forms of money laundering to detect, and it also overlaps with sanctions evasion and proliferation financing.

Why is TBML hard to detect?

Banks usually see the payment or the trade finance document, not the goods. International trade involves many parties, documents and jurisdictions, much of the paperwork is still manual, and a legitimate shipment looks very similar to a fraudulent one unless prices and goods are checked against reliable data. Large trade volumes also give criminals cover.

SymphonyAI’s FinCrime Frontier 2026-27 survey found that 20.4% of financial crime professional respondents see trade-based money laundering as one of the risks growing most in importance, alongside sanctions evasion at 30.9%.

What are the main TBML techniques?

Technique What happens Typical red flag
Over-invoicing Goods are invoiced above their value, so the buyer pays extra value to the seller Price well above market
Under-invoicing Goods are invoiced below their value, so value passes to the buyer in another way Price well below market
Multiple invoicing The same shipment is invoiced and paid for more than once Duplicate invoices or payments
Phantom shipments Documents describe trade, but no goods move Shipping or customs records that do not match
Misdescription of goods The type, quality or quantity of goods is misstated Description inconsistent with the buyer’s business
Black market peso exchange Dealers use trade to settle debts between currency markets and launder drug proceeds Third-party payments from unrelated parties

What are the red flags of TBML?

There are many red flags of trade-based money laundering:

  • Prices that differ sharply from market values
  • Goods that do not fit the customer’s business or profile
  • Payments from or to unrelated third parties
  • Discrepancies between invoices, shipping documents and payments
  • Unusual shipping routes, or use of free trade zones with no clear reason
  • Complex or opaque ownership, such as shell companies
  • Frequent amendments to letters of credit or contract terms
  • Vague descriptions of goods, or dual-use goods that raise sanctions concerns
  • Links to high-risk jurisdictions

How do firms detect TBML?

  1. Know the customer and the trade. Strong KYC and CDD should capture what a customer trades, with whom and where, so deviations stand out, supported by ongoing due diligence.
  2. Look through ownership. Identify the ultimate beneficial owners behind buyers, sellers and intermediaries.
  3. Check the documents. Compare invoices, bills of lading, letters of credit and payments for inconsistencies, and benchmark prices against reliable market data.
  4. Monitor behavior and networks. Use transaction monitoring and entity resolution to find patterns across related parties.
  5. Screen for sanctions exposure. Check parties, goods, vessels and routes using sanctions screening, since TBML often overlaps with sanctions evasion and implicit sanctions risk.
  6. Escalate. Apply enhanced due diligence where risk is high and file a suspicious activity report where suspicion remains.

How does AI help?

AI can read and compare unstructured trade documents, flag price and description anomalies at scale and link parties across networks that manual review would miss. Agentic AI can assemble the evidence for an analyst to review, with a full audit trail. See how SymphonyAI transaction monitoring supports this.

FAQs

What is the difference between TBML and traditional money laundering?
Traditional laundering typically moves money through accounts and financial products. TBML uses trade transactions, such as false invoices, to move value.

Which institutions are most exposed to TBML?
Banks involved in trade finance, correspondent banking and cross-border payments, along with freight, logistics and trading firms.

Is TBML linked to sanctions evasion?
Often. The same techniques, including false descriptions, shell companies and third-party payments, are used to evade sanctions and move dual-use goods. The FinCrime Frontier 2026-27 report also highlights trade-based evasion and shell structures as techniques that challenge screening built primarily around static list matching.

Who sets the standards on TBML?
FATF and the Egmont Group have published guidance on trade-based money laundering, including risk indicators to help firms spot it.
