The Multivariate Option iPoD Framework - Assessing Systemic Financial Risk

Philipp Matros and Johannes Vilsmeier

No 143, Working Papers from Bavarian Graduate Program in Economics (BGPE)

Abstract: We derive multivariate risk neutral asset distributions for major US nancial institutions (FIs) using option implied marginal risk neutral asset distributions (RNDs) and probabili- ties of default (PoDs). The multivariate densities are estimated by combining the entropy approach, dynamic copulas and rank correlations. Our density estimates exhibit information about the conditional distributions of the individual FIs and we propose several nancial distress measures based on default scenarios taking place in the nancial sector. Empirical results around the period of the US sub-prime crisis show that the proposed risk measures in a timely manner identify i) the most troubled FIs in the system, ii) the systemically most important FIs, iii) the implicit bailout guarantees of some FIs and iv) a `too interconnected to fail' problem in the US nancial sector throughout the year 2008.
