Purpose: The study aims to explore the case study method with the formation of questions, data collection procedures and analysis, followed by how and on which position the saturation is achieved in developing a centralized Shariah governance framework for Islamic banks in Bangladesh.Design/methodology/approach: Using purposive and snowball sampling procedures, data have been collected from 17 respondents who are working in the central bank and Islamic banks of Bangladesh through face-to-face and semi-structured interviews.Findings: The study claims that researchers can form the research questions by using “what” question mark in qualitative research. Besides, the qualitative research and case study could explore the answers of “what” questions along with the “why” and “how” more broadly, descriptively and extensively about a phenomenon. Similarly, saturation can be considered attaining the ultimate point of data collection by the researchers without adding anything in the databank. Overall, this study proposes three stages of saturation: First, information redundancy. Second, referring the respondents (already considered in the study) without knowing anything about the data collection and their responses. Third, through the NVivo open coding process due to the decrease of reference or quotes in a certain position or in the saturation position as a result of fewer outcomes or insufficient information. The saturation is thus achieved in the diversified positions, i.e. three respondents for regulatory, nine for Shariah scholars and officers and five for the experts concerning the responses and respondents.Research limitations/implications: The study has potential implications on the qualitative research method, including the case study, saturation process and points, NVivo analysis and qualitative questions formation.Originality/value: This research defines a case study with the inclusion of “what” and illustrates the saturation process in diverse positions. The qualitative research questions can also be formed with “what” in addition “why” and “how”.

The conflict between Russia and Ukraine has been causing knock-on effects worldwide. The supply and price of major commodity markets (oil, gas, platinum, gold, and silver) have been greatly impacted. Due to the ongoing conflict, financial markets across the world have experienced a strong dynamic regarding commodities prices. This effect can be considered the biggest change since the occurrence of the financial crisis in the year 2008, which explicitly influenced the oil and gold markets. This study attempts to investigate the impacts of the Russian invasion crisis on the dynamic connectedness among five commodities and the G7 and BRIC (leading stock) markets. We have applied the time-varying parameter vector autoregressive (TVP-VAR) method, which reflects the way spillovers are shaped by various crises periods, and we found extreme connectedness among all commodities and markets (G7 and BRIC). The findings show that gold and silver (commodities) and the United States, Canada, China, and Brazil (stock markets) are the receivers from the rest of the commodities/market’s transmitters of shocks during this invasion crisis. This research has policy implications that could be beneficial to commodity and stock investors, and these implications could guide them to make many decisions about investment in such tumultuous situations. Policymakers, institutional investors, bankers, and international organizations are the possible beneficiaries of these policy decisions.

Purpose: The purpose of this paper is to examine the influences of Shariah governance (SG) mechanisms on Islamic banks' performance and Shariah compliance quality in the context of Bangladesh.Design/methodology/approach: A semi-structured personal interview tactic was applied to accomplish the research objectives. The data were collected from the regulators, Shariah supervisory boards, Shariah department executives and Shariah experts from the Central Bank (Bangladesh Bank) and Islamic banks in Bangladesh.Findings: The study discovers that the quality of the Board of Directors (BODs), Shariah Supervisory Board (SSB), management and Shariah executives have both positive and negative influences on the Shariah compliance quality, image, goodwill and performance of Islamic banks' in Bangladesh. The compositions, formations and quality of SSB and Shariah officers positively influence the Islamic banks' fatwas, Shariah decisions, compliance quality and firm performance. The study also finds that prevailing banking pressure, current political situation, the willingness of BOD and management and social limitations impact Islamic banks' performance, Shariah compliance quality, image and goodwill.Research limitations/implications: Based on our findings, if the regulators, BODs and Islamic banks can manage effective and efficient executives, it will create a positive impact on Islamic banks' performance, image, goodwill and quality compliance. As the prevailing banking pressure, current political situation and social limitations hinder the functions and employment system of the Islamic banks as well as result the Islamic banks' image, performance, Shariah implementations and compliance. Thus, the theorist needs to consider these mechanisms in extending the agency, stakeholder and resource dependence theories.Originality/value: This research extends the literature concerning the influences of Islamic banks' SG mechanisms in Bangladesh. The study also argued not only the efficient and effective mechanisms but also the prevailing banking pressure, current political situation and social limitations impact on Islamic banks' performance and Shariah compliance quality.

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.

Purpose: The purpose of this paper is to explore the question “Why is Shariah Governance Framework (SGF) important for Islamic banks?”Design/methodology/approach: A semi-structured face-to-face personal interview is used to accomplish the research objectives. This study has collected data from the concerned bodies related to Shariah Governance (SG) from the central bank and Islamic banks of Bangladesh.Findings: This study states SG as a process of confirming Shariah compliance in the overall functions of the Islamic banks, while Shariah denotes some rules, regulations, guidelines, objectives and directions to enhance accurate functions and activities, which are solely based on Shariah principles. SGF is important for Islamic banks to implement Shariah principles, confirm Shariah compliance and monitor the functions of the banks. Besides, it is needed for a well, efficient, effective, profitable business and higher performance and, finally, to eliminate the confusion among the management, executives, conventional bankers and banks.Research limitations/implications: This study significantly contributes to the national and global regulatory bodies by providing evidence that why do Islamic banks and financial institutions require a sound SGF. It is recommended that there should be a sound and robust SGF to protect and fulfill the interest, expectations and demands of different stakeholders, which can easily draw their attention, intention and interest.Originality/value: This is the first research that extends the literature of Islamic banking and SG by highlighting the importance of SGF. This study claims that to be a complete Islamic bank as well as protecting the unique identity from the general banks and corporate governance system, SG manual is required.
