This paper investigates banking and sovereign distress in the Eurozone and the importance of direct and indirect financial exposures. We use BIS cross-border banking claims to link member states in a GVAR framework and jointly model sectoral CDS premia. Based on balance sheet positions of an intermediate debtor country, we calculate indirect exposures and asses how the level of interconnectedness is impacted when indirect links are accounted for. We notice a general slowdown in financial integration and a reduction in cross-border assets in the hope of limiting international contagion. By differentiating between direct and indirect links, we show that the impact of reduced weights on core member states is mostly insignificant and that deleveraging strategies are not generally able to successfully reduce risk.

A power law typically governs the tail decay of financial returns but the constancy of the so-called tail index which dictates the tail decay remains relatively unexplored. We study the finite sample properties of some recently proposed endogenous tests for structural change in the tail index. Given that the finite sample critical values strongly depend on the tail parameters of the return distribution we propose a bootstrap-based version of the structural change test. Our empirical application spans developed and emerging financial asset returns. Somewhat surprisingly, emerging stock market tails are not more inclined to structural change than their developed counterparts. Emerging currency tails, on the contrary, do exhibit structural shifts in contrast to developed currencies. Our results suggest that extreme value theory (EVT) applications in hedging tail risks can assume stationary tail behavior over long time spans provided one considers portfolios that solely consist of stocks or bonds.
