ABSTRACT
Disrupting events like COVID-19, climate change or new competitors (e.g., GAFAM) can permanently change the structure of a bank's balance sheet and the bank's risk profile. Agent-based modeling (ABM) is a versatile, interdisciplinary bottom-up approach that can be used to consider such effects in dynamic simulations of the balance sheet development. The authors present a concept for an agent-based model that simulates the effects of macroeconomic scenarios and competitive boundaries on the balance sheet dynamics of banks. An implementation of such a model could be used to explore stylized balance sheet developments over time and thereby provide a valuable planning tool for qualitative and quantitative risk management. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.
