Innovations, Fragility and Complexity: Understanding the Power of Finance

This article examines financial innovation as a source of structural power of finance originally identified by Susan Strange. I build a synthesis based on complex network theory and the field of evolutionary finance which yields a conception of finance as a complex ecological habitat. On the one hand, the interaction between various entities inhabiting the financial system endows this complex habitat with a tangible degree of autonomy vis-a-vis politics, society and economy. On the other hand, the evolutionary process guiding this financial ecology is built on complexity and innovation and hence is fragile. The structural power of finance today, therefore, is necessarily twofold: it manifests the effects of the endeavours (intentional and otherwise) of financial agents; crucially, it also rests on the seemingly boundless ability of the financial system to adapt, change and evolve.
