This article critically analyzes agrarian finance in terms of household credit and debt in the global south. I introduce interdisciplinary concepts about agrarian finance before reviewing how political ecologists and development geographers have studied this topic in relation to agricultural production, social reproduction, and farm mortgages and dispossession. To advance this research, I engage with financial geography scholarship about financial ecologies and variegated financial capitalism. I argue that agrarian finance is always embedded in the agricultural practices and interdependencies of rural life, but that such relations are increasingly shaped by global finance capital governed by institutions operating at multiple scales.
