Examining the Impact of the Global Financial Crisis on the Deposit Banks’ Level of Systematic Risk: Evidence from AR(p)-DCC-FIGARCH (p,d,q) and Asymmetric AR(p)-DBEKK-GARCH (p, q) Models

This study examines the impact of the 2007–2008 global financial crisis on the time-varying conditional systematic risk level of nine deposit banks using AR(p)-DCC-FIGARCH (p,d,q) and asymmetric AR(p)-DBEKK-GARCH (p,q) models under the assumption of a multivariate Student’s t distribution. Results show that the systematic risk level of two large-scale banks, in particular, significantly increased during the crisis period. The systematic risk level of two small- and medium-sized banks also significantly increased during the crisis period. Additionally, one-break unit root tests applied to all banks’ systematic risk coefficients show that all these series are stationary at their level form
