What happened
FATF and regional financial intelligence assessments through 2026 have continued to highlight the diversification of terrorist financing methods used by armed groups across the Sahel, Lake Chad Basin, Somalia and Mozambique, with informal gold trading, kidnap-for-ransom and cross-border smuggling networks assessed as increasingly significant revenue streams alongside more traditional taxation of local populations and trade. Reporting from ISS Africa and regional financial intelligence units has flagged artisanal gold mining zones in Mali, Burkina Faso and Sudan as particular points of concern, where armed groups reportedly tax, control or directly participate in extraction and trading.
Kidnap-for-ransom activity attributed to groups linked to al-Qaeda and Islamic State affiliates in the Sahel, as well as al-Shabaab in Somalia and Kenya, has remained a persistent revenue source, with reported ransom payments — while rarely confirmed publicly — assessed by regional analysts to run into the tens of millions of dollars cumulatively across the region in recent years.
Why it matters
The diversification of terrorist financing away from easily traceable formal-sector transactions and toward informal, cash-based and commodity-linked economies makes existing anti-money-laundering and countering-the-financing-of-terrorism (AML/CFT) frameworks significantly less effective. Gold in particular is difficult to trace once it enters informal supply chains, can be transported easily across porous borders, and retains value independent of any documentation — making it, in the assessment of several FATF-linked reports, one of the more attractive financing instruments for armed groups operating across the Sahel and Horn.
This matters directly for businesses and financial institutions operating in or transacting with counterparties linked to affected regions, since regulatory expectations around sanctions and CFT due diligence are tightening even as the underlying financing methods become harder to detect through conventional transaction monitoring.
How the threat is evolving
The financing landscape has evolved in three notable ways. First, groups have moved from opportunistic taxation of existing informal economies toward more direct involvement in production and trade — controlling mining sites, setting prices, and in some cases operating their own trading networks rather than merely taxing third parties. Second, kidnap-for-ransom has professionalised, with reported negotiation structures, established payment channels and, in some cases, apparent coordination between geographically separate cells suggesting shared financing infrastructure. Third, smuggling networks — for fuel, subsidised goods, and in some cases narcotics transiting the Sahel — have become financing sources in their own right, blurring the line between purely criminal and ideologically motivated armed actors.
The financing of Sahelian and Horn armed groups increasingly resembles organised-crime economics with an ideological veneer, and countering it requires the tools of financial crime investigation as much as counter-terrorism doctrine.
- Reported expansion of armed-group involvement in or taxation of artisanal gold mining zones in Mali, Burkina Faso and Sudan.
- Frequency and reported value of kidnap-for-ransom incidents attributed to Sahelian, Lake Chad Basin and Somali armed groups.
- Evidence of cross-border smuggling network overlap between criminal and ideologically motivated armed actors.
- FATF and regional FIU findings on gold and informal-economy-linked terrorist financing typologies.
- New or tightened AML/CFT regulatory measures targeting informal gold trade and cash-based cross-border transfers.
Security implications
Kidnap-for-ransom risk to staff operating in or transiting Sahelian, Lake Chad Basin and Somali border regions remains a direct duty-of-care concern independent of the financing dimension, and organisations should treat the professionalisation of ransom negotiation infrastructure as an indicator that armed groups view kidnapping as a durable, low-risk revenue stream rather than an opportunistic tactic — meaning the threat is likely to persist rather than fade.
Business implications
Financial institutions, commodity traders and any company with exposure to gold sourced from or transiting affected regions face growing regulatory and reputational risk if due diligence does not adequately trace informal supply chains back through mining and trading points potentially linked to armed-group taxation or control. Compliance teams should treat informal gold trade due diligence as a distinct, higher-risk category requiring enhanced scrutiny rather than folding it into generic conflict-minerals processes designed primarily around Great Lakes tin, tantalum, tungsten and gold (3TG) frameworks.
NGO/humanitarian implications
Humanitarian agencies face two distinct exposures: direct kidnap-for-ransom risk to staff in affected regions, and indirect compliance risk where counter-terrorism financing legislation intersects with humanitarian principles of impartial access, particularly where agencies must engage or negotiate access with groups that also participate in financing networks under sanctions or CFT scrutiny. Legal and compliance teams should work closely with security and access teams to avoid inadvertent exposure while preserving the ability to negotiate humanitarian access.
- Enhance due diligence specifically on informal gold supply chains distinct from standard 3TG conflict-minerals processes.
- Reassess kidnap-for-ransom risk ratings for Sahel, Lake Chad Basin and Somali border operations at least annually.
- Build closer coordination between compliance/legal and access/security teams on CFT exposure in access negotiations.
- Monitor FATF mutual evaluation reports and regional FIU typology updates for emerging financing methods.
What to monitor next
Track FATF and regional financial intelligence unit typology reports for updated assessments of gold- and smuggling-linked terrorist financing, ACLED kidnap-for-ransom incident data across the Sahel and Somalia, and any new sanctions designations targeting individuals or networks involved in informal gold trade linked to armed groups.
