Abstract

To capture non-smooth changes in dynamic dependence, we incorporate a factorial hidden Markov regime-switching model within the factor Copula framework. This approach allows us to construct a factorial hidden Markov (FHM) factor Copula model that captures external shocks of varying magnitude, direction and short or long-term effect from significant events to multi-dimensional dependence. Additionally, given the favorable properties of RVaR and the cumulative effects of risk spillover, we propose the concept of multi-CoRVaR and present explicit calculation formulas derived from the constructed models. Finally, empirical analysis is conducted to study the cross-country risk spillovers in order to assess the risk faced by one country when other countries encounter extreme situations.
