This chapter outlines a particular way of assessing the financial system and its participants. This approach arises in the aftermath of the financial crisis, and has to do with the nature of financial calculation and what it may have done to our understanding of financial sociability. It develops arguments made in the previous three chapters, and links these explicitly to the issues of the deterritorialization and re-territorialization of financial activity in our so-called ‘globalizing’ world. What can be done to redress the imbalance that has arisen between domestic economic and financial activity, and its ‘global’ counterpart? Would it be possible to reterritorialize such activity and, if so, how and in what forms? These are the issues pursued in the latter part of the chapter.
