This open access book examines the often overlooked entanglements and affinities between emerging models of formal and informal finance and welfare with longer-running religious structures and concerns. In Kenya has long mediated microcredit contracts and the social contract between citizens and the state.In effect, mutual aid has been organized in ways that contributed to mistrust in financial and state institutions as well as among families and neighbours.Nevertheless, diverse mutual aid arrangements have thrived and proliferated, not least because collaborating parties actively recognize the influence of invisible third parties such as God or Satan.The resulting forms of trust and mistrust range from the contractual to the mutual and everything in-between.Together, they highlight how speaking of trust in a language of religious faith sustains possibilities for contingency, creativity, and change alongside the reproduction of pre-existing inequalities and moral prejudices.
