Cash and voucher assistance (CVA) has become a widespread humanitarian tool to support people affected by conflicts, displacement, and disasters. It promises improved ways to meet the diverse needs of aid beneficiaries. Current policy and academic debates mainly centre on technocratic questions concerning economy, effectiveness, and equity, and, to a lesser extent, the effects on individual recipients and households. This paper challenges the assumption of CVA as a linear process and argues that the shift to CVA is more than changing the aid delivery platform. It contends that scholarship and practice have so far overlooked the social meaning of money, and therefore its broader implications for humanitarian aid and local markets. The paper presents evidence that CVA impacts on social relations and risks creating new, or exacerbating existing, conflicts in already fragile contexts. It highlights less explored areas of CVA and outlines a multidimensional research agenda that emphasises its potential social and socioeconomic consequences.
