Risk spillovers and interconnectedness between systemically important institutions

In this paper we gauge the degree of interconnectedness and quantify the linkages between global and other systemically important institutions, and the global financial system. We document that the two groups and the financial system become more interconnected during the global financial crisis when linkages across groups grow. In contrast, during tranquil times linkages within groups prevail. Global systemically important banks contribute most to system-wide distress, but are also most exposed. Other systemically important institutions bear more individual market risk. The two groups and the global financial system also co-vary for periods of up to 60 days. In sum, both groups perform in ways that defy any straightforward categorization
