Purpose Prior studies on Islamic finance provide a limited linkage between organizational theory and the complex Shariah governance framework embraced by Islamic banks worldwide. This paper aims to show the relevance of the application of “institutional theory” in the Shariah governance framework of Islamic banks. Design/methodology/approach This study applied library research to investigate the application of institutional theory in the Shariah governance framework of Islamic banks. The authors also critically reviewed prior empirical and review papers for accomplishing the research objectives. Findings Based on the critical review, the authors found that institutional theory is the most influential in progressing Shariah governance as it contributes toward the organizational image, helps to achieve religious legitimacy, and inspires a more robust regulatory environment. In addition, a well-designed Shariah governance framework is driven by institutional theory and that could assist in providing guidelines, strategies and procedures for Islamic banks to better conduct; monitor and control their social, religious and accountability obligations. The authors also highlighted the societal, economic and legal environment of Islamic banks in relation to the propositions of institutional theory. They emphasize that a well-designed Shariah governance framework driven by institutional theory could assist in providing guidelines, strategies and procedures for Islamic banks to better conduct, monitor and control their social, religious and accountability obligations. Research limitations/implications This study highlights institutional theory to serve best the development of operational strategies and structures of Islamic banks including the roles, functions and powers of the various stakeholders including regulators and those involved in the Shariah governance process of Islamic banks. The authors recognize the institutional theory to perform a key role in enriching the structural framework of Islamic Financial Institutions. This study is heavily dependent on prior research rather than empirical investigations. The authors did not cover other Islamic finance areas (such as Islamic insurance, Islamic microfinance and Halal industries). Thus, future researchers can apply institutional theory in Shariah governance practices and implementations of setting up rules by the regulators and respective institutions. Originality/value To the best of the authors’ knowledge, this is the first study that attempts to show the importance of the application of institutional theory in Shariah governance of Islamic Banks. Thus, this study, therefore, adding a novel dimension to the literature by arguing why institutional theory, is more pronounced (as compared to the other theoretical frameworks) in the formation and discharge of the roles, powers and functions by the different governance organs (such as regulators, the board of directors, management and Shariah supervisory board) operating in this unique corporate governance landscape.
