The policy mobility literature is haunted by the local–global binary and the problem of understanding the extent to which a particular policy is ‘local’ or ‘global’. This paper argues that while an assemblage perspective is already prominent in the literature, its use can be extended to more effectively engage with this problem. Proceeding from the recognition that what makes mobile policy possible is first and foremost the existence of separate policy territories, through a focus on the kinds of assemblages that territorialise separate but interconnected territories, and a more thoroughgoing account of the topologies contained by those assemblages, we can account for how mobile policy is an outcome of this work of assemblage. It is through such assemblages that our ideas of what is global and what is local are produced. The example of the technocracy is used to illustrate the argument.
