This paper examines German and foreign bank factors that can explain cross-border central bank liquidity flows between Germany and the rest of the euro area. Using data from the German component of Eurosystem's real-time gross settlement system TARGET2 and BankFocus for the period between 2009...

This paper proposes rules for the control of interbank rate volatility under different interest corridor systems when volatility stems from interbank market frictions. Friction-induced volatility will occur if there is heterogeneity in two dimensions (across banks and time) with respect to the...

This paper studies a central bank's optimal interest rate corridor choice in the presence of an endogenous interbank network. We first provide a characterization of the unique equilibrium of banks' liquidity holdings for any network of credit lines. Then, we endogenize the network and show that...

We develop a model in which financial intermediaries hold liquidity to protect themselves from shocks. Depending on parameter values, banks may choose to hold too much or too little liquidity on aggregate compared with the socially optimal amount. The model endogenously generates a situation of...

We present a two-country model with an enhanced banking sector featuring risky lending and cross-border interbank market frictions. We find that (i) the strength of the financial accelerator, when applied to banks operating under uncertainty in an interbank market, will critically depend on the...
