We investigate systemic risk and how financial contagion propagates within the euro area banking system by employing the Maximum Entropy method. The study captures multiple snapshots of a dynamic financial network and uses counterfactual simulations to propagate shocks emerging from three...

In this paper we present a methodology of model-based calibration of additional capital needed in an interconnected financial system to minimize potential contagion losses. Building on ideas from combinatorial optimization tailored to controlling contagion in case of complete information about...

We study the frictions in the patterns of trades in the Euro money market. We characterize the structure of lending relations during the period of recent financial turmoil. We use network-topology method on data from overnight transactions in the Electronic Market for Interbank Deposits (e-Mid)...

This paper provides evidence of a highly fragmented European interbank market that is tightened during the COVID-19 pandemic, when the interbank market was under stress. Using a unique dataset of unsecured, overnight interbank loans at the transactional level allows me to apply advanced panel...

From 2004 to 2015, the market perception of the sovereign risks of the Euro area government bonds experienced several different phases, reflected in a clear time structure of the correlation matrix between the yield changes. "Core" and "peripheral" bonds cluster in a bloc-like structure, but the...

In this paper, we analyze the dynamic relationships between ten stock exchanges of the euro zone using Granger causal networks. Using returns for which we allow the variance to follow a Markov-Switching GARCH or a Changing-Point GARCH, we first show that over different periods, the topology of...

The paper reports the outcome of the stress-testing of liquidity risk in the TARGET2 payment system, with the study having been conducted by an ad-hoc group composed of operators and overseers of TARGET2. The study aims to assess the resilience of the system, defined as the network of its...

The paper studies the central bank collateral framework and its impact on banks’ liquidity under an adverse stress test scenario. We construct a stress test model that accounts for a granular and multi-faceted representation of the liquidity of marketable and non-marketable assets. In...
