Finance interrupted: Social impact bonds, spatial politics, and the limits of financial innovation in the social sector

An enduring legacy of the 2007–2009 financial crisis is the growth of “social” and “impact” investing, markets dedicated to the use of financial capital to achieve social good. This paper examines one key manifestation of these markets: the social impact bond, a financial device which uses private capital to fund social programs. While social impact bond (SIBs) have been viewed as a testament to the power of finance and the “financialization” of the social sector, the paper instead highlights the struggles and limits of the SIB enterprise. Informed by a multi-year study of SIBs in Canada, the USA, and UK, and the theoretical lens of the social studies of assetization combined with an ecological approach, these struggles are conceived in terms of the challenge of operationalizing SIBs’ financial imaginary and managing the gaps between finance and the social sector as distinct ecologies. Particular emphasis is placed on three valuation devices—liquidity, risk, and rigor—which are central to this effort. Rather than “hinges” connecting these worlds, these devices have emerged as points of conflict, revealing a distinctly spatial politics which helps to explain the limits not only of SIBs but also other forms of financialization at the frontiers of (social) finance.
