African central banks
AML compliance with AI · 2023-2024
Several African central banks faced a duplicated problem: traditional anti-money-laundering (AML) monitoring systems generated thousands of alerts per day, but 95% were false positives. Investigators spent hours closing useless alerts and lost the few relevant cases in the noise. International regulatory pressure (FATF, Basel) demanded ever-higher standards of effectiveness.
Build a transactional monitoring system based on machine learning that (a) drastically reduced false positives without losing critical patterns, (b) was adaptable to different regulatory contexts across African countries, (c) could be adopted by investigation teams without AI background.
Designed and implemented an ML-driven transactional monitoring framework with three key components: multi-level anomaly detection that learns from investigator feedback, supervised pattern recognition transaction scoring, automated compliance process for low-risk cases. The architecture was designed to adapt to different regulatory frameworks without rewriting the core.
40% reduction in false positives. 60% increase in investigation speed. Framework adopted as operational standard. The system is currently active in multiple African jurisdictions with local configurations.
In regulated sectors, AI works when it reduces unnecessary work for experienced operators, not when it promises to replace them. The success was less technical and more organizational: convincing experienced investigators the system was an ally.
