This paper uses a toy financial system to study systemic risk in scale-free interbank networks. Networks are produced according to a fitness algorithm, combined with a representation of the balance sheets of the banks. Our generating processes for interbank networks are designed in a way to...

While net settlement systems make more efficient use of liquidity than gross settlement systems, they are known to generate systemic risk. What does that tendency imply for the stability of the payments [or financial] system when the two settlement systems coexist? Do liquidity shortages induce...

Our results uncover a so far undocumented ability of the interbank market to distinguish between banks of different quality in times of aggregate distress. We show empirical evidence that during the 2007 financial crisis the inability of some banks to roll over their interbank debt was not due...

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....

We study the functioning of secured and unsecured inter-bank markets in the presence of credit risk. The model generates empirical predictions that are in line with developments during the 2007-2009 financial crises. Interest rates decouple across secured and unsecured markets following an...

We study the functioning and possible breakdown of the interbank market in the presence of counterparty risk. We allow banks to have private information about the risk of their assets. We show how banks’ asset risk affects funding liquidity in the interbank market. Several interbank market...

This paper tests the hypothesis of liquidity hoarding in the Italian banking system during the 2007-2011 global financial crisis. According to this hypothesis, in periods of crisis, interbank markets stop working and central banks’ interventions are ineffective because banks hoard the...

We empirically investigate why wholesale funding is fragile by providing the first study of how individual banks borrow and lend in the euro unsecured and secured interbank market. Consistent with theories in which lenders enforce market discipline by monitoring counterparty credit risk and...

The interbank market is important for the efficient functioning of the financial system, transmission of monetary policy and therefore ultimately the real economy. In particular, it facilitates banks' liquidity management. This paper aims at extending the literature which views interbank markets...
