Abstract: This paper investigates how banking system stability is affected when we combine Islamic and conventional finance under the same roof. We compare systemic resilience of three types of banks in 6 GCC countries with dual banking systems: fully-fledged Islamic banks (IB), purely conventional banks (CB) and conventional banks with Islamic windows (CBw). We employ market-based systemic risk measures such as MES, SRISK and DeltaCoVaR to identify which sector is more vulnerable to a systemic event, and use graphical network models to determine the banking sector that can more easily spread a systemic shock to the whole system. Using a sample of 2,608 observations on 79 publicly traded banks operating over the 2005-2014 period, we find that CBw is the least resilient sector to a systemic event and is more interconnected with other banks during crisis times.
