Quantifying systemic risk in US industries using neural network quantile regression

The study quantified the systemic risk spillovers between top 10 US industries using conditional value-at-risk in a network context by calibrating the marginal effects of a quantile regression process and coving period from January 3, 2007-May 28, 2021 and found significant variations in the risk measured using a nonlinear process. Neural networks identified the manufacturing industry as the center of risk spillovers with the disconnected telecommunication industry in a system-wide neural network portraying its diversification potential. The systematic fragility index, which ranks industries with a high exposure to tail risk in a system, revealed the utilities industry as being the most vulnerable to economically fragile periods. By contrast, the systematic hazard index, which measures the risk contribution of an industry, showed the manufacturing industry as the principal risk contributor. With this tail risk assessment, particularly during distress periods, we stipulate several implications for policymakers, regulators, investors, and financial market participants.

Automated summary

This study quantified the systemic risk spillovers between the top 10 US industries using conditional value-at-risk in a network context. The results showed significant variations in risk measured using a nonlinear process, with the manufacturing industry identified as the center of risk spillovers and the telecommunications industry as having diversification potential. The utilities industry was found to be the most vulnerable to economically fragile periods, while the manufacturing industry was the principal risk contributor. These findings have important implications for policymakers, regulators, investors, and financial market participants, particularly during distress periods.
