Intervention On Default Contagion Under Partial Information

Abstract

We model the default contagion process in a large heterogeneous financial network under the interventions of a regulator (a central bank) with only partial information which is a more realistic setting than most current literature. We provide the analytical results for the asymptotic optimal intervention policies and the asymptotic magnitude of default contagion in terms of the network characteristics. We extend the results of Amini et al. (2013) to incorporate interventions and the model of Amini et al. (2015); Amini et al. (2017) to heterogeneous networks with a given degree sequence and arbitrary initial equity levels. The insights from the results are that the optimal intervention policy is "monotonic" in terms of the intervention cost, the closeness to invulnerability and connectivity. Moreover, we should keep intervening on a bank once we have intervened on it. Our simulation results show a good agreement with the theoretical results.
