This project aims to strengthen the statistical capacity of selected countries across regions to measure illicit financial flows (IFFs), while increasing awareness of the globally agreed definitions, concepts, methods and tools in all regions. Second, the project will consolidate methodological guidelines with the aim to produce estimates on IFFs, also by gathering and aggregating existing early estimates (where possible) from different IFF types (tax and commercial and crime-related IFFs) to allow for the reporting of SDG Indicator 16.4.1. Third, the project will strengthen the capacity of beneficiary countries to develop evidence-based policy responses to curb IFFs and strengthen domestic resource mobilization. It is important to note that policy intervention is not limited to using statistical analyses only but will also work towards developing practical tools and actionable policy interventions. For example, the project will aim to enhance investigative capacities in selected countries, extending the statistical methods by using a recently developed algorithm that utilises open-source tools to allow for the cost-effective investigation of IFFs by applying machine learning techniques. As a result, countries will be able to measure and report on IFFs and work towards building a policy response or action agenda to curb IFFs accordingly.
