It is estimated that the proceeds of crime, corruption and tax evasion represent between $1 trillion and $1.6 trillion per year, with half coming from developing countries. Proceeds are typically transferred abroad and hidden in foreign jurisdictions, thus requiring international cooperation. Various international conventions and agreements require international cooperation on this issue, in particular the United Nations Convention against Corruption; however, only $5 billion in stolen assets have been repatriated over the last 15 years. This enormous gap reveals that significant barriers continue to impede asset recovery despite the commitments taken by governments, civil society and the private sector. Drawing on the experience of practitioners with hands-on experience, the Stolen Asset Recovery (StAR) Initiative launched this study to identify the barriers to stolen asset recovery internationally, provide brief analysis of the impact of these barriers, and propose recommendations for overcoming these obstacles. This volume is intended to guide policy makers in their efforts to ensure necessary resources and the development of a plan, policy or strategy aimed at eradicating the barriers to asset recovery. In addition, this study proposes actions to be taken by the G20, international organizations, financial institutions, developmental agencies and civil society.
