Abstract
This study examines the spillovers from Crude Oil price fluctuations to sovereign credit risk, proxied by CDS spreads for 16 oil exporters and importers belonging to G20. Besides measuring shocks from Crude Oil to sovereign risk, it also examined the system-wide impacts of CDS shocks to understand their magnified impacts within a system. Furthermore, the study finds the channels that have the potential to act as a carrier of shocks from Crude Oil to sovereign risk considering four country-specific and two global factors. Our study deployed Generalized Impulse Response Functions and Generalized Forecast Error Variance Decomposition for being independent of ordering. Additionally, DCC-GARCH has been applied to test the robustness of the results. Our results highlight higher spillovers to oil-exporting countries from Crude Oil when compared to oil importers, irrespective of their development stage. Interestingly, developed countries are severely impacted by net system-wide shocks from developing and oil-exporting countries. Moreover, Global factors play a dominant role in carrying the shocks from Crude Oil to sovereign risk of countries. Stock market indices are important among important domestic factors that act as carriers of shocks, and VIX is robust amongst global variables. Our results are valuable to Regulators, policymakers, portfolio managers, banks, and financial institutions for proactively planning their respective policies.
期刊介绍：
The purpose of the journal is also to stimulate international dialog among academics, industry participants, traders, investors, and policymakers with mutual interests in commodity markets. The mandate for the journal is to present ongoing work within commodity economics and finance. Topics can be related to financialization of commodity markets; pricing, hedging, and risk analysis of commodity derivatives; risk premia in commodity markets; real option analysis for commodity project investment and production; portfolio allocation including commodities; forecasting in commodity markets; corporate finance for commodity-exposed corporations; econometric/statistical analysis of commodity markets; organization of commodity markets; regulation of commodity markets; local and global commodity trading; and commodity supply chains. Commodity markets in this context are energy markets (including renewables), metal markets, mineral markets, agricultural markets, livestock and fish markets, markets for weather derivatives, emission markets, shipping markets, water, and related markets. This interdisciplinary and trans-disciplinary journal will cover all commodity markets and is thus relevant for a broad audience. Commodity markets are not only of academic interest but also highly relevant for many practitioners, including asset managers, industrial managers, investment bankers, risk managers, and also policymakers in governments, central banks, and supranational institutions.
