Panel modeling of z-score: evidence from Islamic and conventional Saudi banks

Purpose This paper aims to measure the stability extent of the banking sector in Saudi Arabia, including Islamic and conventional banks (CBs), using quarterly data. Design/methodology/approach The paper uses seemingly unrelated regressions to estimate the determinants of the z-score. Findings The panel data model shows that Islamic banks (IBs) reduce the financial stability index relatively; meanwhile, they contribute efficiently to enhance the financial stability through the diversification of their assets. The Saudi banking sector exhibits strong concentration affecting the financial stability negatively. Research limitations/implications The paper’s topic can be extended to cover the recent period. Practical implications The limited presence of IBs in the Saudi banking sector jeopardizes any effort to improve the financial stability. Social implications By attracting more clients, IBs would contribute more to the financial stability in the Saudi economy. Also, the monetary authority has to expand the share of IBs in the financial system at least 50-50 compared to CBs. Originality/value The z-score is mostly analyzed with yearly data; in this paper we use quarterly data to describe at infra-annual frequency the variability of the z-score index. Also, we consider in detail the statistical properties of the banks’ data.
