ISOR Colloquium

"Dynamic Default Contagion in interbank systems"

Speaker: Andreas Sojmark (Imperial College London)

! Due to the Covid-19 safety measures the talk will take place ONLINE ONLY !

Oskar-Morgenstern-Platz 1, 1090 Wien


In this talk we start by introducing a simple model for interbank default contagion in the vein of the seminal network models of Eisenberg--Noe (2001) and Rogers--Veraart (2013). The key feature, and main novelty, consists in combining stochastic dynamics with a simple but realistic balance sheet methodology for determining early defaults together with a Gai--Kapadia (2010) style contagion mechanism. After first developing the model for a finite number of banks, we present a natural way of passing to the mean field limit such that the network structure for interbank obligations is respected in a meaningful way. Thus, we provide a clear connection between the more classical network-based literature on systemic risk and the emerging literature on mean-field models more rooted in stochastic analysis.
