What is the role of imagination in the constitution of finance capitalism? How do the fictions, myths, and (ir)rationalities of finance shape society's ability to imagine the future in the face of mounting political instability? Well over a decade since the Global Financial Crisis of 2008, today's financialised economies are still marred by stagnation and uncertainty. Against this backdrop, the increasingly speculative nature of economic forecasting, and the accelerated trading of promises of all sorts (from algorithmic and derivative markets to contemporary electoral politics) put the role of imagination centre stage. This special issue contends that, contrary to conventional wisdom, imagining the future is not necessarily equal to ‘fantasising' or to ‘irrational exuberance' or the ‘animal spirits'. Rather, it points to something much more fundamental: the power of finance to produce new social and political morphologies under conditions of radical uncertainty. The articles of the special issue confront these issues by mapping out a novel field of investigation into different, unique types of imagination undergirding finance capitalism in the years since its most recent crisis: from the future-making practices of mineral exploration and agricultural derivative markets, to the imagined futures of financial education programmes, the financialisation of creative work, and the role of future-oriented legitimacy in today’s populist politics
