Following the Money: Financial Flows Behind Human Trafficking and Forced Labour Networks

Human trafficking and forced labour represent some of the most serious human rights violations occurring globally — and they are, at their core, profit-driven criminal enterprises. The International Labour Organization (ILO) estimates that forced labour generates USD 236 billion in illegal profits annually, making it one of the largest illicit economies in the world. For financial institutions, this translates into a clear obligation: the financial flows associated with human trafficking and forced labour pass through the banking system, and the ability to detect and disrupt them is both a compliance requirement and a moral imperative.

The financial typologies associated with human trafficking are diverse and context-dependent. Sex trafficking operations generate cash-intensive proceeds that are laundered through hospitality businesses, massage parlours, and online platforms. Labour trafficking in agriculture, construction, and domestic services may involve legitimate employment structures that mask wage theft, debt bondage, and movement control. Modern slavery in global supply chains creates financial flows that are deeply embedded in legitimate trade and corporate banking relationships — making detection particularly challenging.

FATF’s Financial Flows from Human Trafficking report established a foundational typology framework that financial institutions have been expected to operationalise in their AML programmes. Yet implementation remains uneven, with many institutions treating human trafficking as a peripheral AML risk rather than a mainstream threat typology that warrants dedicated detection scenarios, staff training, and intelligence-sharing engagement.

Regulatory, Enforcement, and Market Context

Regulatory frameworks addressing human trafficking-related financial flows have expanded significantly. In the United States, FinCEN has issued advisories on human trafficking red flags, and the Bank Secrecy Act has been interpreted to require financial institutions to file SARs on suspected trafficking-related activity. The UK’s Modern Slavery Act imposes reporting obligations on large businesses and has prompted financial institutions to review both their own supply chains and those of their commercial customers. Australia’s Modern Slavery Act requires mandatory reporting from entities with annual revenues exceeding AUD 100 million.

The Egmont Group has published financial intelligence unit guidance on human trafficking detection, emphasising the role of proactive financial intelligence analysis in identifying trafficking networks before victims can be identified through law enforcement channels. The UN Office on Drugs and Crime’s Blue Heart campaign and the OSCE’s financial intelligence guidance both provide frameworks for institution-level implementation. Public-private partnerships including the Polaris Project’s Financial Industry Program have demonstrated the value of shared typologies and red flag indicators in improving SAR quality and law enforcement utility.

What the Data Is Showing

FinCEN analysis of SAR data has revealed persistent red flag patterns in human trafficking-related financial activity: multiple individuals sharing a single address, sending similar amounts to the same recipients; frequent cash deposits inconsistent with stated business type; commercial accounts with high volumes of small, regular payments to individuals with no apparent employment relationship; and hotel, motel, or short-term rental payments made alongside payments to escort or adult entertainment services. These patterns, taken together, significantly increase the probability of trafficking-related financial activity.

The nexus between Southeast Asian scam compound operations and human trafficking is now well-documented. The UNODC estimates that hundreds of thousands of individuals have been trafficked into scam compound compounds in Myanmar, Cambodia, and Laos to work as forced fraud operators. This creates a unique financial intelligence challenge: the institutions receiving scam proceeds may simultaneously be enabling the financial infrastructure of human trafficking operations.

Implications for Financial Institutions

Institutions should implement dedicated human trafficking detection scenarios within their transaction monitoring systems, drawing on FinCEN advisories, Egmont Group guidance, and jurisdiction-specific red flag lists. These scenarios should be reviewed and updated annually, incorporating intelligence from law enforcement engagements and SAR feedback loops. Human trafficking risk should be explicitly included in the enterprise-wide risk assessment, with particular attention to sectors and customer types that present elevated exposure — including hospitality, staffing agencies, agriculture, construction, and adult entertainment.

Supply chain due diligence for corporate banking customers operating in high-risk sectors is increasingly a regulatory expectation. Institutions providing trade finance, working capital, or transactional banking to companies in sectors with known forced labour risks should consider how their commercial KYC and ongoing monitoring programmes can identify potential supply chain exploitation. Engagement with NGO partners and specialist data providers can augment traditional KYC data with supply chain risk intelligence.

Conclusion

The financial system is simultaneously the greatest enabler and the greatest potential disruptor of human trafficking and forced labour. Institutions that invest in genuine detection capability — not merely box-ticking scenario libraries — contribute meaningfully to the disruption of some of the world’s most harmful criminal enterprises. This is an area where compliance and conscience are perfectly aligned.

Suggested Next Steps

• Implement dedicated human trafficking transaction monitoring scenarios drawing on FinCEN advisories, Egmont Group typologies, and jurisdiction-specific red flag lists, reviewed and updated at least annually.

• Explicitly include human trafficking and modern slavery risk in your enterprise-wide risk assessment, with sector-specific risk ratings for hospitality, staffing, agriculture, construction, and adult entertainment customers.

• Develop supply chain due diligence protocols for corporate banking customers in high-risk sectors, integrating specialist data providers and NGO intelligence into the KYC and ongoing monitoring process.

• Engage with public-private partnership initiatives such as the Polaris Project Financial Industry Program and equivalent national programmes to access shared typology intelligence and improve the operational utility of your SAR submissions.
