This paper gives an overview of the recent literature on bank business models, structured along what we deem to be the three central questions when analysing business models. By doing so, we endeavour to provide the recent shift in prudential supervision towards the analysis of bank business models with a sound economic basis. The bottom-line for supervisors - in our view - is that it is essential to understand where the profit comes from and what risks the bank or the banking sector is exposed to in generating those profits.
Key words: banking, business model.
