Networks of monetary flow at native resolution Carolina Mattsson∗1 1 Network Science Institute, Northeastern University, Boston, MA, USA arXiv:1910.05596v1 [physics.soc-ph] 12 Oct 2019 October 15, 2019 Abstract People and companies move money with every financial transaction they make. We aim to understand how such activity gives rise to large-scale patterns of monetary flow. In this work, we trace the movement of e-money through the accounts of a mobile money system using the provider’s own transaction records.

Common sequential motifs correspond to known use-cases of mobile money: digital payments, digital transfers, and money storage. We find that each activity creates a distinct network structure within the system, and we uncover coordinated gaming of the mobile money provider’s commission schedule. Moreover, we find that e-money passes through the system in
