Set in a context where material accumulation is valorized, this article analyzes narratives of sika bone (bad money) as expressions of economic uncertainty by market women operating in an era of increased financialization. The ethnographic evidence supports previous arguments about the impact of economic change in this millennium, a change that fosters both rationality and superstition in equal measure. Salifu proposes that sika bone indicates a sense of uncertainty fostered by economic change in the supply of cash and formal credit, a sentiment that is expressed by applying old notions about occultic means of accumulation to new and equally enigmatic circumstances.
