Introduction

Across Africa, trade has always been more than an economic activity — it is a lifeline connecting communities, markets, and neighbouring countries. From informal traders moving goods across borders in West Africa to agricultural and commodity networks linking East and Southern Africa, informal trade corridors support millions of livelihoods.

However, the same characteristics that make these networks flexible and resilient can also create vulnerabilities exploited by criminal actors. Among the most complex financial crime threats affecting global commerce is Trade-Based Money Laundering (TBML) — the process of disguising the proceeds of crime and moving value through legitimate trade transactions.

While TBML is often associated with sophisticated international supply chains, it also presents significant challenges within Africa’s informal and semi-formal trade ecosystems, where cash transactions, limited documentation, fragmented regulation, and cross-border complexity can create opportunities for abuse.

The challenge is not that informal trade is inherently criminal. Informal commerce provides essential income for millions of Africans and plays a critical role in regional economic integration. The challenge is understanding where legitimate economic activity ends and where criminal exploitation begins.

Understanding Trade-Based Money Laundering

Unlike traditional money laundering methods that rely primarily on financial institutions or cash movements, TBML uses the movement of goods and services to transfer value.

Criminal networks may manipulate trade transactions by:

Over-invoicing goods to move additional value across borders;
Under-invoicing exports to hide the true value of transactions;
Misrepresenting the quantity or quality of goods;
Creating false trade documentation;
Using phantom shipments where goods do not actually exist.

For example, a criminal organisation may purchase goods at an inflated price from an overseas supplier. The excess payment represents a transfer of illicit funds disguised as a normal commercial transaction.

Unlike a simple suspicious bank transfer, TBML can appear legitimate because there is often an underlying business activity: goods are shipped, invoices exist, and companies may have years of trading history.

This makes detection significantly more difficult.

Africa’s Informal Trade Corridors: Economic Engine and Vulnerability

Informal cross-border trade is a fundamental part of Africa’s economic landscape.

Across regions such as:

West Africa (ECOWAS corridors);
East Africa (Kenya–Uganda–Tanzania trade routes);
Southern Africa (South Africa and neighbouring markets);

small traders transport agricultural products, textiles, electronics, household goods, and consumer products across borders every day.

Many of these transactions operate outside traditional banking channels due to:

Limited access to formal financial services;
High transaction costs;
Currency exchange challenges;
Complex border procedures;
Lack of formal business registration.

The Financial Action Task Force (FATF) recognises that large informal economies can create vulnerabilities for money laundering because criminal actors may exploit cash-intensive environments and informal financial mechanisms.

However, a key point must be emphasised:

Informality does not equal criminality.

Millions of informal traders are legitimate entrepreneurs operating in environments where formal systems may not always be accessible or practical.

The AML challenge is therefore not eliminating informal trade, but improving transparency and financial inclusion.

How Criminal Networks Exploit Informal Trade Corridors

Criminal organisations often take advantage of the characteristics that make informal trade efficient.

1. Cash-Based Transactions

Cash remains common in many informal markets.

Large volumes of cash transactions can make it difficult to establish:

Source of funds;
Beneficial ownership;
True commercial purpose.

Criminal networks may use legitimate traders as intermediaries or exploit existing trading relationships to introduce illicit funds into commerce.

2. Misrepresentation of Goods and Prices

Commodity trading creates opportunities for manipulation.

Examples include:

Declaring cheap goods as high-value products;
Inflating import prices;
Falsifying quantities;
Using multiple invoices for the same shipment.

These methods allow criminals to move value while avoiding traditional transaction monitoring systems.

3. Complex Regional Supply Chains

African trade corridors often involve multiple actors:

Suppliers;
Transport companies;
Customs agents;
Importers;
Wholesalers;
Retailers;
Informal brokers.

The more participants involved, the harder it becomes to identify who ultimately controls the transaction.

TBML investigations are challenging precisely because criminals exploit legitimate commercial relationships and international supply chains.

4. Commodity-Based Money Laundering

Certain commodities can be particularly attractive because they are:

Highly valuable;
Easy to transport;
Difficult to price consistently.

Examples include:

Gold;
Precious stones;
Agricultural commodities;
Fuel products.

Gold flows from Africa have received particular international attention due to concerns around undeclared exports, smuggling networks, and illicit financial flows.

Why Detecting TBML Is Difficult

Traditional AML systems are generally designed around financial transactions:

Bank transfers;
Card payments;
Account activity;
Suspicious transaction patterns.

TBML requires a different approach.

A suspicious payment may only become visible when combined with trade intelligence:

Does the price match market value?
Does the importer normally trade this product?
Is the shipment consistent with the company’s profile?
Are trade partners connected through ownership or control?
Are goods moving through higher-risk jurisdictions?

The FATF and Egmont Group have highlighted the importance of combining financial intelligence with customs, trade, and private-sector information to improve TBML detection.

The Role of Financial Institutions

Banks and payment providers operating in African markets face a difficult balance.

They must manage financial crime risks while ensuring that legitimate businesses and traders are not excluded from financial services.

Key areas of focus include:

Enhanced Customer Due Diligence

Financial institutions should understand:

Nature of the customer’s business;
Trading activity;
Main suppliers and customers;
Expected transaction volumes.

Trade Data Integration

Banks can strengthen monitoring by analysing:

Customs information;
Import/export documentation;
Shipping records;
Commodity prices.

Risk-Based Monitoring

Not every informal trader presents the same risk.

A risk-based approach allows institutions to distinguish between:

A small trader buying goods for a local market;
A complex network moving millions through manipulated trade transactions.

Technology and the Future of TBML Detection

Technology can play an important role in identifying hidden patterns.

Potential solutions include:

Artificial intelligence analysing trade networks;
Entity resolution tools linking companies and individuals;
Graph analytics identifying relationships between traders;
Data-sharing platforms between regulators, customs authorities, and financial institutions.

However, technology alone cannot solve TBML.

Effective prevention requires cooperation between:

Financial intelligence units;
Customs authorities;
Banks;
Payment providers;
Trade regulators;
Private companies.

Moving Towards a More Transparent African Trade Ecosystem

Africa’s informal trade corridors should not be viewed only through a financial crime lens.

They represent:

Entrepreneurship;
Economic resilience;
Regional integration;
Employment opportunities.

The objective should be creating systems where legitimate traders can participate more easily in the formal economy while reducing opportunities for criminals.

Possible solutions include:

Digital payment adoption;
Simplified business registration;
Better border cooperation;
Improved customs transparency;
Financial inclusion initiatives;
Stronger public-private partnerships.

Conclusion

Trade-Based Money Laundering represents one of the most complex financial crime challenges facing modern economies.

In Africa, the combination of extensive informal trade networks, cross-border commerce, cash dependency, and evolving supply chains creates both economic opportunity and financial crime risks.

The solution is not restricting trade or penalising informal entrepreneurs. Instead, the focus should be on building stronger transparency mechanisms, improving access to formal financial services, and connecting financial intelligence with trade intelligence.

Africa’s trade corridors will continue to grow. The challenge for AML professionals, regulators, and financial institutions is ensuring that this growth supports legitimate economic development rather than becoming a channel for criminal finance.
