Introduction To Trade-Based Money Laundering And Over-Invoicing
Trade-Based Money Laundering is a sophisticated method of moving illicit funds into the financial system by manipulating international trade transactions. At its core, TBML takes advantage of the complexity and sheer volume of global trade. An estimated 250 to 300 million containers move around the world annually, yet only one to two percent are physically inspected. This reality presents criminals with opportunities to move money undetected, often by distorting the price, quantity, or quality of goods crossing borders.
Unlike traditional laundering routes, trade is harder to track. Financial institutions may process payments, but they rarely verify the physical goods behind the transactions. Customs authorities, meanwhile, focus on tariffs and contraband, not financial crime. This gap between trade and finance is the sweet spot in which TBML thrives. Over-invoicing, under-invoicing, faking entire shipments – these techniques allow launderers to integrate illegal funds into the economy under the radar.
The term “trade-based money laundering” was created by John Cassara, a retired US intelligence officer who countered money laundering and terrorist financing for 26 years. The concept emerged from the recognition that trade transactions provide a uniquely effective vehicle for laundering money due to the volume and complexity of global trade. Unlike cash smuggling, which involves physically moving currency across borders, TBML integrates illicit funds into the legitimate financial system through seemingly legitimate commercial transactions.
The Scale Of The TBML Problem
The scale of the challenge is significant. Estimates suggest that 2 to 5 percent of global GDP, as much as $5.5 trillion annually, is laundered worldwide, with a significant share flowing through trade. Trade-based money laundering remains one of the most exploited channels for money laundering and the illicit movement of funds.
Specific estimates vary widely. The Financial Action Task Force’s most-cited estimate puts TBML at roughly $1.6 trillion annually, a number some analysts consider an undercount, with some suggesting the true figure may be closer to $2 trillion. Whatever the truth, the trajectory is hardly improving. Rising tariffs have increased the incentive to manipulate invoice values. Sanctions regimes have pushed sanctioned entities to exploit trade channels as an alternative to the now-scrutinised correspondent banking network.
In some countries, the problem is even more acute. A 2024 white paper estimated annual trade-related outflows from Bangladesh at $16 billion, equivalent to 3.4 percent of GDP – more than the nation’s total yearly health budget. According to the National Board of Revenue, nearly 75 percent of domestic money laundering occurs through trade channels in Bangladesh. Globally, the Global Financial Integrity estimated the gap between developing and advanced economies’ export and import declarations at $8.7 trillion for 2008-2017, a figure that indicates the approximate extent of TBML worldwide.
Understanding Over-Invoicing And Under-Invoicing
Over-invoicing and under-invoicing are the most fundamental and widely used TBML techniques.
Over-Invoicing: This involves deliberately overstating the value of goods on an invoice. For example, exporting goods valued at $1 per unit but invoicing them at $100 allows launderers to shift illicit funds under the guise of legitimate trade. The buyer transfers more money than the goods are worth, moving value across borders under commercial cover. This technique allows a criminal to move funds out of a country by making it appear that the importer is paying for high-value goods that do not actually exist or that are worth far less than the stated value.
Under-Invoicing: This involves deliberately understating the value of goods on an invoice. By declaring goods at a lower value, the seller can repatriate funds in plain sight, below the threshold of suspicion. This technique can be used to evade customs duties and taxes, and also to move value out of a country by making it appear that the exporter is receiving less than they actually are for the goods shipped. The difference between the actual value and the declared value represents the illicit transfer of value.
Mechanism Of Over-Invoicing: In a typical over-invoicing scheme, an importer and exporter collude to inflate the value of goods on the invoice. The importer pays the inflated amount to the exporter, who then transfers the excess funds back to the importer or to another account. This allows the importer to move funds out of the country, while the exporter receives a legitimate-looking payment for goods that are worth less than the stated value.
Mechanism Of Under-Invoicing: In a typical under-invoicing scheme, an exporter and importer collude to deflate the value of goods on the invoice. The exporter ships goods worth a certain amount but invoices them at a lower value. The importer pays the lower amount, and the difference between the actual value and the declared value is transferred through other channels. This allows the exporter to move value out of the country while evading customs duties and taxes.
How Over-Invoicing Works In Practice
Over-invoicing is a sophisticated technique that can be implemented through several methods.
Fictitious Invoices: Criminals create entirely fictitious invoices for goods that do not exist. The documents appear legitimate, but there is no actual shipment. The purpose is solely to move funds from one jurisdiction to another. This technique is often used in conjunction with phantom shipments.
Inflated Prices: Criminals use inflated prices for goods that actually exist. The goods are shipped, but the invoice price is significantly higher than the market value. The difference between the market value and the invoiced value represents the illicit transfer of funds.
Multiple Invoicing: Criminals issue multiple invoices for the same shipment of goods. Each invoice is presented to a different bank, and payment is made on each invoice. This allows multiple payments to be made for the same goods, effectively multiplying the value transferred.
Mixed Commodity Invoicing: Criminals combine high-value and low-value goods in a single shipment, invoicing all goods at the high-value rate. This inflates the total value of the shipment and allows for the transfer of excess funds.
Round-Tripping: Criminals use over-invoicing to move funds out of a country and then use other trade transactions to move the funds back in. This creates a circular flow of funds that can be used to launder money and to evade taxes.
How Under-Invoicing Works In Practice
Under-invoicing is a complementary technique to over-invoicing, used for similar purposes.
Customs Evasion: Under-invoicing is commonly used to evade customs duties and taxes. By declaring goods at a lower value, importers reduce the amount of duties and taxes they owe. This is a significant source of revenue loss for governments.
Capital Flight: Under-invoicing is used to move capital out of a country. By under-invoicing exports, exporters receive less payment through official channels, while the difference is transferred through other means. This allows for the illicit transfer of funds out of the country.
Dual Invoicing: Criminals create two sets of invoices for the same shipment: a low-value invoice for customs authorities and a high-value invoice for the actual transaction. The low-value invoice is used to reduce duties and taxes, while the high-value invoice reflects the true value of the transaction.
Under-Declaration Of Quantity: Criminals under-declare the quantity of goods shipped. For example, a container might be declared as holding 10,000 units when it actually contains 100,000 units. This allows the exporter to receive payment for 100,000 units while only declaring 10,000 units.
Under-Declaration Of Quality: Criminals under-declare the quality of goods shipped. High-value goods are declared as lower-value goods, reducing duties and taxes and facilitating the illicit transfer of funds.
The Use Of Shell Companies And Complex Structures
Shell companies and complex corporate structures are essential elements of sophisticated over-invoicing and under-invoicing schemes.
Shell Companies: Shell companies are legal entities that have no significant operations or assets. They are created solely to facilitate financial transactions, often to obscure the true ownership and control of funds. In TBML schemes, shell companies are used to issue invoices, receive payments, and transfer funds.
Complex Corporate Structures: Criminal networks use complex corporate structures involving multiple jurisdictions to obscure the true ownership and control of entities involved in TBML. These structures make it difficult for authorities to identify the ultimate beneficiaries of illicit transactions.
Layered Ownership: Criminal networks use layered ownership structures, with multiple layers of companies and trusts, to obscure the true beneficial owners of entities involved in TBML. Each layer adds another degree of separation, making it more difficult to trace the flow of funds.
Offshore Jurisdictions: Criminal networks often use offshore jurisdictions with weak regulatory frameworks to establish shell companies and to conduct TBML transactions. These jurisdictions provide secrecy and limited oversight.
Nominee Directors And Shareholders: Criminal networks use nominee directors and shareholders to obscure the true ownership and control of shell companies. Nominees are individuals who lend their names to companies but have no real involvement in their operations.
The Role Of Trade Finance In Over-Invoicing And Under-Invoicing
Trade finance is a critical component of over-invoicing and under-invoicing schemes.
Letters Of Credit: Letters of credit are a common form of trade finance that can be exploited for TBML. A letter of credit is a guarantee from a bank that payment will be made to the exporter upon presentation of specified documents. Criminals may manipulate the documents to obtain payment for inflated or fictitious transactions.
Documentary Collections: Documentary collections are another form of trade finance that can be exploited. In a documentary collection, the exporter’s bank sends the shipping documents to the importer’s bank, which releases them to the importer upon payment. Criminals may manipulate the documents to facilitate TBML.
Trade Loans: Trade loans are loans provided to finance trade transactions. Criminals may use trade loans to facilitate TBML, by obtaining financing for inflated or fictitious transactions.
Supply Chain Finance: Supply chain finance involves financing the supply chain of a company. Criminals may exploit supply chain finance to facilitate TBML by creating fictitious supply chain transactions.
Trade Finance Intermediaries: Trade finance intermediaries, such as brokers and agents, may be exploited for TBML. These intermediaries may be complicit in the scheme or may be unwittingly exploited.
Red Flags For Over-Invoicing And Under-Invoicing
Several red flags can indicate potential over-invoicing or under-invoicing.
Inconsistent Documentation: Inconsistencies in trade documentation can indicate TBML. This includes discrepancies between invoices, bills of lading, and customs declarations. A classic red flag is when the invoice value is significantly different from the market value of the goods.
Unusual Pricing: Unusual pricing of goods can indicate TBML. This includes over-invoicing, under-invoicing, and pricing that is inconsistent with market values. When the price of goods is significantly above or below the market price, it should raise suspicion.
High-Risk Jurisdictions: Transactions involving high-risk jurisdictions can indicate TBML. This includes jurisdictions with weak regulatory frameworks, high levels of corruption, and those subject to sanctions. Trade between unrelated parties in high-risk jurisdictions is a red flag.
Unusual Routes: Unusual shipping routes can indicate TBML. This includes routing goods through intermediary countries or using transshipment to obscure the origin or destination of goods. Unnecessary routing of goods through multiple jurisdictions should raise suspicion.
Complex Corporate Structures: Complex corporate structures can indicate TBML. This includes the use of shell companies, trusts, and other entities to obscure ownership and control. When the ownership structure of a trading entity is opaque or difficult to trace, it should be considered a red flag.
Unusual Payment Terms: Unusual payment terms can indicate TBML. This includes payments through third parties, payments in cash, and payments in cryptocurrency. Payments made to unrelated third parties, or payments that do not match the invoice value, are indicators of potential fraud. Frequent amendments to letters of credit or trade documentation are also red flags.
Rapid Turnover: Rapid turnover of goods, where goods are imported and then re-exported quickly, can indicate TBML. This can be a sign of trade diversion or phantom shipments. When the same goods are traded repeatedly between the same parties, it can indicate an attempt to create a paper trail for illicit funds.
Complex Over-Invoicing Models
Complex over-invoicing models involve multiple parties, jurisdictions, and transactions.
Multi-Jurisdictional Networks: Criminal networks use multi-jurisdictional networks to conduct TBML. These networks involve entities in multiple countries, making it difficult for authorities to trace the flow of funds. Each jurisdiction adds another layer of complexity, and each transaction moves funds closer to their ultimate destination.
Layered Transactions: Criminal networks use layered transactions to obscure the flow of funds. Multiple transactions are conducted through multiple entities and jurisdictions, making it difficult to trace the origin and destination of funds. Layering is a key technique in money laundering, and TBML provides an effective vehicle for layering.
Trade-Based Layering: Trade-based layering involves using trade transactions to layer funds. Funds are moved through multiple trade transactions, with each transaction obscuring the origin of the funds. This is a sophisticated technique that is difficult to detect.
Integration With Other Financial Crimes: Over-invoicing and under-invoicing are often integrated with other financial crimes, including cybercrime, ransomware, and terrorist financing. This integration makes TBML networks more complex and more difficult to combat.
Use Of Cryptocurrency: Cryptocurrency is increasingly being used in TBML schemes. Digital assets can be transferred across borders quickly and with less oversight than traditional financial instruments. Criminals are beginning to integrate cryptocurrency into their TBML operations, using it to move funds and to obscure the flow of money.
Use Of Free Trade Zones: Free trade zones are areas where goods can be imported, processed, and re-exported without customs duties. These zones are often exploited for TBML because of the reduced oversight and transparency.
Detecting And Preventing Over-Invoicing And Under-Invoicing
Detecting and preventing over-invoicing and under-invoicing requires a multi-faceted approach.
Enhanced Due Diligence: Financial institutions and businesses should conduct enhanced due diligence for trade transactions involving high-risk jurisdictions, high-risk commodities, and unusual trade patterns. This includes verifying the identity of all parties, understanding the nature of the goods, and assessing the risks.
Transaction Monitoring: Financial institutions should monitor trade finance transactions for suspicious activity. This includes monitoring for unusual patterns, anomalies, and red flags. Automated systems can be used to flag potential TBML transactions for further review.
Data Sharing: Data sharing between financial institutions, customs authorities, and law enforcement is essential for detecting TBML. Sharing information on trade transactions, shipping data, and financial intelligence can help to identify suspicious activities.
Use Of Technology: Technology can be used to enhance the detection and prevention of TBML. This includes the use of data analytics, artificial intelligence, and blockchain to monitor trade transactions and to identify anomalies.
Training: Training is essential for detecting and preventing TBML. Financial institutions and businesses should train their employees on TBML techniques, red flags, and reporting requirements. Training should be ongoing and should be tailored to the specific roles of employees.
International Cooperation: International cooperation is essential for combating TBML. Countries must cooperate to share information, to conduct joint investigations, and to coordinate enforcement actions.
Strengthening Regulatory Frameworks: Countries should strengthen their regulatory frameworks to address TBML. This includes implementing FATF recommendations, enhancing customs enforcement, and strengthening anti-money laundering controls.
Conclusion
Over-invoicing and under-invoicing are fundamental techniques used in trade-based money laundering, enabling criminals to move illicit funds across borders under the guise of legitimate trade. These techniques are sophisticated, involving the manipulation of trade documentation, the use of shell companies and complex corporate structures, and the exploitation of trade finance mechanisms. The scale of the problem is significant, with estimates suggesting that TBML accounts for approximately $1.6 trillion to $2 trillion annually. Over-invoicing involves deliberately overstating the value of goods on an invoice, while under-invoicing involves deliberately understating the value. Both techniques are used to move funds across borders, to evade customs duties and taxes, and to launder money. Complex over-invoicing models involve multiple parties, jurisdictions, and transactions, often integrating with other financial crimes and using cryptocurrency and free trade zones. Detecting and preventing over-invoicing and under-invoicing requires enhanced due diligence, transaction monitoring, data sharing, use of technology, training, international cooperation, and strengthening regulatory frameworks. Organizations that understand over-invoicing and under-invoicing are better positioned to detect and prevent TBML, to ensure compliance with international standards, and to contribute to the global fight against financial crime.
