We develop a model where banks invest in reserves and loans, and face aggregate liquidity shocks. Banks with liquidity shortage sell loans on the interbank market. Two equilibria emerge. In the no default equilibrium, all banks hold enough reserves and remain solvent. In the mixed equilibrium,...

Banks' interactions vary in nature from competition to mutually beneficial trading with one another. This creates important links across markets, implying that bank strategies cannot be considered in isolation in a single market. I set up a model where profit-maximizing banks jointly determine...

In this paper, we study how the interbank market could impact deposit competition and bank profits. We first document two stylized facts: the net interbank funding ratio is negatively correlated with net interest margin (NIM), as well as with the cost-to-income ratio (CIR). To rationalize these...
