How Connected is the Global Sovereign Credit Risk Network?, KU-TUSIAD ERF Working Paper, No. 1512, August 2015. (with K Yilmaz) R&R to Journal of Banking and Finance
This paper applies the Diebold-Yilmaz connectedness methodology on sovereign credit default swaps (SCDSs) to estimate the network structure of global sovereign credit risk. The results reveal that emerging market countries are the key generators of connectedness of sovereign credit risk shocks between 2009 and 2014. Developed countries and debt-ridden countries play relatively small roles in the transmission of shocks. Furthermore, important differences between network structures of SCDS returns and volatilities are observed. In return networks, developing and developed countries stand apart in two big clusters. Volatility networks are less connected overall; three clusters are visible where developing countries are further divided into two regional clusters.
