This article presents stylised facts from the euro area network of large exposures and derives model-based interconnectedness measures of SSM significant institutions. The article has three main findings. First, the interbank network is relatively sparse and suggests a core-periphery network structure. Second, the more complex network measures on average correlate highly with the more simple size-based interconnectedness indicators, constructed following the EBA guidelines on the calibration of O-SII buffers. Third, there is nevertheless value for policymakers to take into account network-based measures in addition to the size-based interconnectedness indicators, as for some individual banks those measures can deviate considerably.
