Before revision: The properties of the interbank market have been discussed widely in the literature . However a proper model selection between URLanizations of the network in a small number of blocks, for example bipartite, core-periphery, and modular , has not been performed.
After revision: The properties of the interbank market have been discussed widely in the literature mainly because of their relevance for systemic risk. Here we propose to use the Stochastic Block Model to investigate and perform a model selection among several possible two URLanizations of the network in a small number of blocks, for example bipartite, core-periphery, and modular , has not been performed.
