Running across the intersecting lines that bind and separate the domains of international political economy, international political sociology and human geography, this research sets out to investigate derivatives as both money-form and monetary institutions and practices. To this end, the study draws inspiration, in general, from what has been termed in the social sciences as the practical turn and, in particular, from theoretical and methodological approaches associated with the Actor-Network Theory. By unpacking the notion of financialization and decentering finance, this investigation seeks to grasp actions, practices, objects, strategies that bring together, sustain, authorize and give form to systematic, albeit contingent and unstable, financial and monetary orderings. In the light of the subprime mortgage market of the United States of America, the study will, on the one hand, shed light to mechanisms of assembly of sociotechnical monetary and financial networks, and, on the other hand, unveil the topological workings that dislocate and amplify racial and gendered lines of exclusion. This work of mapping, so I argue, shall open up spaces for critical engagement and shall indicate the limits and possibilities deriving from multiple modes of dissent.
