This paper aims to shed light on the emergence of systemic risk in credit systems. By developing an interbank market with heterogeneous financial institutions granting loans on different network structures, we investigate what market architecture is more resilient to liquidity shocks and how the...

This paper develops a theoretical model which explains several stylized facts observed in the euro area interbank market after the collapse of Lehman Brothers in 2008. The model shows that if transaction costs are high, banks with a liquidity deficit will prefer to borrow liquidity from the...

This paper shows that remunerating required reserves can increase the flexibility of monetary policy. The remuneration at the current repo rate implies constant net marginal interest costs of holding required reserves. This allows the central bank also to change the rate also within a reserve...

This paper provides a first preliminary assessment of the recent two 3-year long-term refinancing operations (3Y LTROs) conducted by the ECB by putting them into a broader context. The perspective taken is that prevailing in the first half of the year 2012, directly after the path-breaking ECB...

This paper investigates the driving forces behind banks' link formation in the interbank market by applying the stochastic actor oriented model (SAOM) developed in sociology. Our data consists of quarterly networks constructed from the transactions on an electronic platform (e-MID) over the...

This paper studies a simple dynamic model of interbank credit relationships. Starting from a given balance sheet structure of a banking system with a realistic distribution of bank sizes, the necessity of establishing interbank credit connections 3merges from idiosyncratic liquidity shocks....

Banks have become increasingly interconnected via interbank credit and other forms of liabilities. As a consequence of the increased interconnectedness, the failure of one node in the interbank network might constitute a threat to the survival of large parts of the entire system. How important...

The aim of this paper is to assess the impact of the interbank market on the business cycle fluctuations. In order to do that, we build a DSGE model with heterogeneous households and banks. The surplus bank can allocate its resources between interbank lending and risk free government bonds. This...
