This chapter examines the effectiveness of the Financial War on Terrorism in light of identifying an emerging terrorist financing typology—coordinated terrorist financing. The chapter begins by undertaking a doctrinal analysis of the international, regional, and domestic counterterrorist financing laws and identifying emerging related typologies. The chapter then moves onto define the Financial War on Terrorism and by using a case study approach illustrates how terrorist organisations are using similar funding methods and, in some instances, using a coordinated approach to raising funds. The case studies focus on natural resources, cryptocurrencies, and coordination between terrorist organisations. The chapter concludes with an assessment of the Financial War on Terrorism in light of the new terrorism financing typology and offers an updated interpretation.
