We undertake a large-scale empirical examination of systemic risk among 1048 financial institutions in a large sample of 23 emerging markets, broken down into 5 regions. This work extends the large literature on systemic risk in the US, Europe, and other developed countries to emerging markets, which is relatively under-researched. We present a novel systemic risk score for each financial system by region, across time. This measure is additively decomposable and attributable to each financial institution, and may be used as an objective and quantifiable measure of whether a bank is a SIFI (systemically important financial institution). The level and timing of systemic risk is heterogenous across the 5 regions, and this risk is concentrated in a few banks, more so pre-crisis than post-crisis. Credit and network effects account for over 2/3 of systemic risk (and in some cases, almost all of the risk), and the remaining comes from individual bank variables. Spillovers of systemic risks across regions are mostly contemporaneous within the quarter. A primary principal component (default level) accounts for 1/2 of the variation in systemic risk across the regions with the next two principal components (policy uncertainty and liquidity) accounting for 1/5 each. Aggregate default risk in a region is statistically predictable using our systemic risk metric, thereby supporting timely macro-prudential policy-making.
