Microfinance is the vanguard of financialization today. This is especially true in Colombia, where microfinance rivals any other type of formal credit. Entangled with Colombia’s micro-financialization is the phenomenon of microfinance corporations in joint ventures with Christian organizations that broker their microfinance programs. These faith-based corporations temper the surge in microfinance with ascetic discipline and the infusion of an entrepreneurial spirit. Economic discipline, say the microfinanciers, is required for what is referred to as ‘financial literacy’ and ‘financial inclusion’ programs that (...) instil a distinctly Christian corporate order. This article, based on 2 years of sustained fieldwork in Colombia, focuses on one such microfinance program run by a transnational Christian credit organization. With microfinance, souls are disciplined through debts and ideals of an ascetic prosperity. In the end, the article concludes that there is a Christian morality to financialized capitalism that is exercised at the level of the interior soul. (shrink)
