Abstract

This paper presents an empirical analysis of the Brazilian interbank network structure. The Brazilian interbank market clearly presents a topology that is compatible to the free-scale networks. This market is characterized by money centers, which have exposures to many banks and are the most important source of large amounts of lending. Therefore, they have important positions in the network taken into account by the minimal spanning tree and the power domination measures of the network. We also develop a methodology to compare di®erent banks and their relative importance in the network.
