Central counterparties and the topology of clearing networks

Given a network of client-clearer relationships, we define central clearing as a function transforming bilateral trading exposures into centrally cleared exposures. By using numerical simulations, we study how this function is affected by the network's topology, focusing on the exposures of the central counterparty. By assuming that margin requirements are a linear function of exposures, we also draw conclusions as to how the network topology affects aggregate margin requirements.
