Purpose

Despite the growing prevalence of Sukuk issuances, there remains a significant knowledge gap concerning their specific risk exposures to originators of issuances rather than to investors, particularly compared to conventional bonds, and the implications of this for the corporate governance (CG) of originators. This study aims to examine the risks faced by originators and sponsors of Sukuk issuances, drawing insights from unique Sukuk case studies. The distinct characteristics of Sukuk include legal intricacies and Shari’ah compliance, which pose particular challenges to originators. Effective risk management is a key issue for CG in these areas.

Design/methodology/approach

A sequential explanatory case study method is employed, utilising the content analysis approach to extract information from various articles, reports and Sukuk case studies, including Tamweel Residential Mortgage Backed Sukuk and Tamweel Sukuk Limited.

Findings

The findings underscore the critical issues for originators in navigating risks within Sukuk structures, particularly concerning Shari’ah non-compliance and default risk. This highlights the importance of managing risks inherent in Sukuk structures, considering both Shari’ah compliance obligations and the sustainability of Sukuk in terms of default risk. Default scenarios raise unique questions regarding stakeholders' interests, specifically those of shareholders, investors and creditors, contingent on the Sukuk issuance's structure and contractual basis of the Sukuk issuance.

Practical implications

The need for a CG framework conducive to the effective management of these risks, thereby ensuring both Shari’ah compliance and long-term viability, which is crucial for the sustainable growth of Sukuk in the financial landscape.

Originality/value

This study offers a unique perspective by focusing on the risks faced by originators of Sukuk issuances, a largely unexplored area, and underscores the importance of effective risk management for CG and sustainability of Sukuk issuances.

目的尽管伊斯兰债券(Sukuk)的发行越来越普遍,但关于其对发行者而非投资者的具体风险敞口(特别是与传统债券相比)以及这对发行者的公司治理(CG)的影响,仍然存在着巨大的知识差距。本研究旨在从独特的伊斯兰债券案例研究中汲取启示,探讨伊斯兰债券发行的发起人和保荐人所面临的风险。伊斯兰债券的显著特点包括法律的复杂性和伊斯兰教法的合规性,这给发起人带来了特殊的挑战。在这些领域,有效的风险管理是 CG 的一个关键问题。研究结果研究结果强调了发起人在应对伊斯兰债券结构中的风险时所面临的关键问题,尤其是在伊斯兰教法不合规和违约风险方面。这凸显了管理伊斯兰债券结构中固有风险的重要性,既要考虑伊斯兰教法的合规义务,又要考虑伊斯兰债券在违约风险方面的可持续性。违约情景提出了有关利益相关者利益的独特问题,特别是股东、投资者和债权人的利益,这取决于伊斯兰债券发行的结构和伊斯兰债券发行的合同基础。实际影响需要一个有利于有效管理这些风险的企业管治框架,从而确保伊斯兰教法合规性和长期可行性,这对伊斯兰债券在金融领域的可持续发展至关重要。独创性/价值本研究提供了一个独特的视角,重点关注伊斯兰债券发行人所面临的风险--这在很大程度上是一个尚未开发的领域,并强调了有效风险管理对于伊斯兰债券发行的企业管治和可持续性的重要性。

研究目的 在本研究中,我们测试了由 NSS 模型计算出的收益率与计算出的传统金融和伊斯兰金融之间的远期利率之间的套利机会,以了解是否存在套利机会。研究问题是:传统金融和伊斯兰金融的收益率是否处于同一水平且彼此相等,以避免套利?传统金融和伊斯兰金融的远期利率是否存在显著差异,从而产生任何套利机会?本研究旨在发现传统金融和伊斯兰金融收益率之间是否存在套利。设计/方法/途径NSS 模型是计算收益率和远期利率的最新模型。在该方法中,误差水平最小化,因此预期收益率和给定收益率都趋于一致(Vahidin 和 Anastasios,2020 年)。收敛后,研究人员就能得到所有 6 个月的收益率。对于纳尔逊-西格尔法,所有六个月的收益率都可用,这些收益率可用于计算远期利率。这表明,由于存在显著差异,套利是可能的。因此,任何人都有兴趣获得有保障的利润。传统收益率较低;因此,任何人都可以从传统金融体系借钱,然后将钱投资到伊斯兰金融体系,因为在伊斯兰金融体系中,投资以收益率的形式获得更高的收益率。因此,人们可以利用这种差异赚钱。从统计学角度看,赚钱是可能的,但实际上,作者观察到的差异却非常微小。伊斯兰金融与传统金融之间的套利机会不会影响经济,因为两者之间的显著差异太小。研究局限/意义本研究没有涉及衍生品合约在风险管理中的作用,未来的研究人员可以将其作为另一项研究。此外,本研究还将有助于监管机构和投资银行家协助解决当前和未来的损失,尤其是传统金融和伊斯兰金融中的债券投资组合。社会影响实际上,这项研究将加强金融体系、资本市场和债券市场,期权合约、期货合约、掉期合约和远期合约等衍生品合约将使用计算出的远期利率来评估未来损失(风险价值 [VaR])并对冲损失(Balakrishnan,2020 年)。

本研究的目的是调查和比较伊斯兰合作组织(OIC)选定国家中伊斯兰银行和传统银行的动态杠杆政策。为实现研究目标,本研究使用了三个不同时期的数据:危机 I(2007-2009 年)、危机 II(2011-2012 年)和危机 III(2020 年)。研究结果研究结果表明,伊斯兰银行和传统银行都表现出杠杆顺周期性。有趣的是,与传统银行相比,伊斯兰银行在正常情况下表现出较弱的杠杆顺周期性,但在危机期间表现出较强的顺周期性。前景理论的应用表明,在某些金融和市场绩效指标作为收益与损失条件的一级领域下,两类银行都会通过杠杆作用表现出冒险或规避风险的行为。此外,在危机期间(作为正常与危机条件的二级域),伊斯兰银行和传统银行的杠杆率都会上升。值得注意的是,与传统银行相比,伊斯兰银行由于风险较低和抗冲击能力较强,在业绩不佳和危机恶化期间,通过杠杆作用承担风险的行为较少。这些发现验证了前景理论在两级领域视角下的适用性。研究的局限性/启示研究的局限性包括:危机时期(危机一、二和三)不尽相同,导致对危机影响的研究不平衡;某些金融和市场表现指标未能证实预期假设;研究结果在选定的伊斯兰会议组织国家之外的推广性有限。实践意义了解伊斯兰银行和传统银行杠杆政策的复杂动态和行为方面,尤其是在危机情况下,对于审查银行法规、做出明智的金融决策和有效管理风险至关重要。首先,它强调了伊斯兰银行杠杆顺周期性的动态性质,表明与传统银行相比,伊斯兰银行从正常情况下较弱的顺周期性转变为危机期间较强的顺周期性。其次,它通过引入双层领域背景,扩大了前景理论的应用范围。研究伊斯兰会议组织国家内不同危机期间伊斯兰银行和传统银行的杠杆政策比较,为杠杆顺周期性和行为反应提供了新的见解。

Purpose

This study aims to investigate the determinants of employees’ readiness to adapt to the change from the conventional banking system to the Islamic banking system in Libya. The determinants identified by this research include supervisors’ support, trust in leadership, participatory management, employees’ involvement in the change, the attitude of top management towards the change, openness towards the change and nature of change.

Design/methodology/approach

The study adopted a quantitative approach by using a self-administered questionnaire survey where a total of 482 sets of questionnaires were distributed manually of which 316 completed questionnaires were found to be usable. The structural equation modelling techniques were used to test and validate the proposed model.

Findings

Statistically, the study found that supervisor support, employees’ involvement in the change process and openness towards change showed significant relationships on employees’ readiness to perform their jobs in Libyan banks where the conventional financial system had been changed to the Islamic banking system. However, on the contrary, trust in leadership, participatory management and the attitude of top management towards the change process were found to have no significant relationship towards employees’ readiness. In addition, a significant moderation effect of the nature of change has been found on the relationship between openness to change and employees’ readiness for change.

Practical implications

Determinants of employees’ readiness for the transformation process identified in the present study can be used in assessing the employees’ readiness before implementing any change. In fact, openness and willingness towards change were found to be significant factors in employees’ readiness in the transformation process. Therefore, banks can use this information as one of the important criteria in recruiting employees. Open-minded and receptive attitudes towards change could be the quality of employees that banks should look for.

Originality/value

Overall, this study can be considered as novel because its findings will prompt other researchers to conduct and expand similar research in this field. Specifically, the findings of this research could facilitate the Central Bank of Libya in identifying their readiness gaps and organisational obstacles that stalled the move of conventional banks in Libya to migrate into the Islamic banking system.

目的 本研究旨在调查利比亚员工是否准备好适应从传统银行体系向伊斯兰银行体系转变的决定因素。本研究确定的决定因素包括主管的支持、对领导的信任、参与式管理、员工对变革的参与、高层管理人员对变革的态度、对变革的开放性以及变革的性质。研究结果从统计学角度看,研究发现,在利比亚银行中,上司的支持、员工对变革过程的参与以及对变革的开放性与员工是否准备好履行其工作职责有显著关系,而在利比亚银行中,传统金融体系已转变为伊斯兰银行体系。然而,与此相反,对领导的信任、参与式管理和高层管理者对变革过程的态度与员工的就绪程度没有显著关系。此外,研究还发现,变革的性质对变革开放度和员工变革准备度之间的关系具有重要的调节作用。事实上,研究发现开放性和变革意愿是影响员工在转型过程中是否做好准备的重要因素。因此,银行在招聘员工时可将这一信息作为重要标准之一。总体而言,本研究具有新颖性,因为其研究结果将促使其他研究人员在这一领域开展和扩展类似的研究。具体而言,本研究的结果可帮助利比亚中央银行找出其准备差距以及阻碍利比亚传统银行向伊斯兰银行系统迁移的组织障碍。

Purpose

The practices of sustainable and responsible investment (SRI) among Islamic financial institutions (IFIs) nowadays still rely on the existing environmental, social and governance (ESG) criteria. However, based on observation, some of the existing criteria listed by the reports of certain authorities and organizations do not seem to be aligned with Shariah principles. Therefore, this study aims to investigate those criteria to help develop Islamic-SRI (i-SRI) criteria based on the ESG concept.

Design/methodology/approach

This study adopted the qualitative method via content analysis of documents and interviews with experts.

Findings

Based on the analysis, a set of i-SRI criteria is developed based on the ESG concept, of which 33 elements are environmental, 50 elements are social and 26 elements are governance issues. Overall, this study finds that there is no obvious contradiction with the Islamic philosophy in the existing ESG criteria, with the exception of four criteria, i.e. promoting human rights, freedom of expression, freedom of censorship and freedom of association under social criteria. These four existing criteria are not aligned with Islamic teaching and not appropriate with Islamic ESG criteria.

Practical implications

The creation of Islamic ESG criteria can assist relevant authorities to improve the current ESG criteria and to embed an Islamic perspective within it.

Originality/value

This study developed a set of i-SRI criteria, which may be suitable as a source of reference to relevant parties.

目的 如今,伊斯兰金融机构(IFIs)的可持续和负责任投资(SRI)实践仍然依赖于现有的环境、社会和治理(ESG)标准。然而,根据观察,某些权威机构和组织的报告中列出的一些现有标准似乎与伊斯兰教法原则并不一致。因此,本研究旨在调查这些标准,以帮助制定基于 ESG 概念的伊斯兰社会责任投资(i-SRI)标准。研究结果根据分析结果,制定了一套基于 ESG 概念的 i-SRI 标准,其中 33 个要素是环境问题,50 个要素是社会问题,26 个要素是治理问题。总体而言,本研究发现,除了社会标准中的促进人权、言论自由、审查自由和结社自由四项标准外,现有的 ESG 标准与伊斯兰理念并无明显矛盾。这四项现有标准与伊斯兰教义不符,也不适合伊斯兰环境、社会和公司治理标准。原创性/价值本研究制定了一套伊斯兰环境、社会和公司治理标准,可供有关方面参考。

Purpose

This study aims to examine the impacts of global geopolitical risks (GPRs) and COVID-19 pandemic stringency on the size of Sukuk issuance in Malaysia.

Design/methodology/approach

To examine the issue, this paper collected yearly data for the Sukuk issuance from the DataStream, and the rest of the variables, including the control variables from the World Bank, were from 2018 to 2022. Several econometric approaches have been used, that is, ordinary least square (OLS), two-stage least squares (2SLS) and generalized method of moment (GMM) with fixed effects and random effects in examining the impacts.

Findings

The results demonstrate that global GPRs negatively impact the size of Sukuk issuance due to the investment risk during the high global geopolitical conflicts, war and rampant terrorism. Besides, the COVID-19 pandemic-related stringency also similarly affects the country's Sukuk issuance market because of the long-time lockdown measures, border closures, travel restrictions and low access to the market. The control variables also demonstrate similar results except for the gross domestic products, which shows positive and significant impacts on the Sukuk market of Malaysia.

Originality/value

The study's policy implications for Sukuk investors and issuers stress the importance of disclosing risk mitigation procedures, strengthening the regulatory framework and raising investor knowledge to attract and protect investors in the Sukuk sector.

目的本研究旨在考察全球地缘政治风险(GPRs)和COVID-19大流行病的严格性对马来西亚伊斯兰债券发行规模的影响。为了考察这一问题,本文从DataStream中收集了伊斯兰债券发行的年度数据,其余变量,包括来自世界银行的控制变量,均为2018年至2022年的数据。本文采用了几种计量经济学方法,即普通最小二乘法(OLS)、两阶段最小二乘法(2SLS)和广义矩量法(GMM),并使用固定效应和随机效应来研究其影响。研究结果表明,在全球地缘政治冲突、战争和恐怖主义猖獗的高发期,由于投资风险的存在,全球GPRs对伊斯兰债券的发行规模产生了负面影响。此外,与 COVID-19 大流行相关的严格性也同样影响了该国的伊斯兰债券发行市场,原因是长期封锁措施、边境关闭、旅行限制和市场准入较低。除了国内生产总值对马来西亚伊斯兰债券市场有积极和显著的影响外,其他控制变量也显示出类似的结果。 原创性/价值该研究对伊斯兰债券投资者和发行者的政策影响强调了披露风险缓解程序、加强监管框架和提高投资者知识以吸引和保护伊斯兰债券领域投资者的重要性。

Purpose

This paper aims to portray the publication pattern, key themes, study trends and future directions for the studies on ethics in Islamic finance. A total of 194 published documents that includes journal articles, books and book chapters and conference proceedings were screened for the period 1988 to August 2022 and categorized based on designated sectors of the Islamic finance industry. This paper also highlights the change in research trends in all three sectors of Islamic finance and suggests possible areas for future research.

Design/methodology/approach

A comprehensive systematic literature review was conducted using the “advanced search” function of “google scholar” by using the option “find articles” with the keywords “Ethic (s/al)”, “Islamic banks”, “Islamic banking”, “Islamic finance”, “Islamic capital markets” Takaful, Islamic insurance without restricting the time frame, author list and the platform. Furthermore, the search for relevant articles was conducted on other mainstream index databases such as “Web of Science” and “Scopus”.

Findings

Among the highlights of the findings were an increase in publications on ethical issues after the global financial crisis and an increase in publications in high-impact mainstream business and finance journals. A higher number of studies were documented in the area of Islamic banking and finance followed by Islamic capital markets and Islamic insurance/Takaful. Although a greater number of empirical studies were published than conceptual studies, dominance was resulted due to the replication of the studies in various jurisdictions based on the same concepts or models rather than applying diversified concepts in various jurisdictions.

Originality/value

This study contributes to the growing literature on ethical and/or Islamic finance as a guide for researchers to identify research gaps and provides a systematic direction for future studies in the area of ethics in Islamic finance.

目的 本文旨在描绘伊斯兰金融伦理研究的出版模式、关键主题、研究趋势和未来方向。本文筛选了 1988 年至 2022 年 8 月期间发表的 194 篇文献,包括期刊论文、书籍和章节以及会议论文集,并根据伊斯兰金融业的指定领域进行了分类。本文还强调了伊斯兰金融业所有三个领域研究趋势的变化,并提出了未来研究的可能领域。设计/方法/途径使用 "google scholar "的 "高级搜索 "功能,在 "查找文章 "选项中输入关键词 "Ethic (s/al)"、"伊斯兰银行"、"伊斯兰银行业"、"伊斯兰金融"、"伊斯兰资本市场"、"回教保险"、"伊斯兰保险",在不限制时间范围、作者列表和平台的情况下进行了全面系统的文献综述。此外,还在 "Web of Science "和 "Scopus "等其他主流索引数据库中搜索了相关文章。研究结果的亮点包括:全球金融危机后,有关伦理问题的出版物有所增加,在影响力大的主流商业和金融期刊上发表的出版物也有所增加。伊斯兰银行和金融领域的研究数量较多,其次是伊斯兰资本市场和伊斯兰保险/回教保险。虽然发表的实证研究多于概念研究,但占主导地位的原因是在不同司法管辖区根据相同的概念或模型重复研究,而不是在不同司法管辖区应用多样化的概念。

Quantitative framework for shariah-compliant multi-period fuzzy portfolio optimization: a sustainable approach to ethical investing 符合伊斯兰教法的多期模糊投资组合优化定量框架:道德投资的可持续方法
IF 2.2 Q2 BUSINESS, FINANCE Pub Date : 2024-07-08 DOI: 10.1108/jiabr-02-2024-0052
Moad El Kharrim

Purpose

This paper aims to propose a Shariah-compliant multi-period fuzzy portfolio optimization model that accounts for Shariah compliance through purification processes and incorporates various Shariah constraints, including sustainability constraints. This model aims to ensure both ethical alignment and robust portfolio management while navigating modern financial complexities and fostering responsible and sustainable investment practices.

Design/methodology/approach

The methodology involves a dynamic programming method to solve the proposed program, with returns of the assets assumed to be trapezoidal fuzzy variables. This approach allows for the quantification of portfolio return and risk by the possibilistic mean and semivariance of the fuzzy returns, respectively. A numerical study based on real stock market data tests the efficiency of the proposed algorithm.

Findings

The research showcases the model’s effectiveness in managing Shariah-compliant portfolios under financial uncertainties and supports the importance of incorporating ethical and sustainability constraints in investment decisions. It highlights the capability of the proposed model to offer a structured approach to ethical investing within the Islamic finance framework.

Research limitations/implications

While the paper provides a solid foundation for Shariah-compliant portfolio optimization, it acknowledges the complexity and computational demands of the model. Future research could explore simplifying the model without compromising its ethical and Shariah-compliant principles.

Originality/value

This work introduces a novel integration of Shariah compliance with fuzzy portfolio optimization techniques, addressing the need for dynamic, ethical investment strategies in Islamic finance. The incorporation of purification processes and sustainability constraints into a fuzzy portfolio optimization model represents a unique contribution to the field.

目的 本文旨在提出一种符合伊斯兰教法的多期模糊投资组合优化模型,该模型通过净化过程说明符合伊斯兰教法,并纳入各种伊斯兰教法约束,包括可持续性约束。该模型旨在确保道德一致性和稳健的投资组合管理,同时驾驭现代金融复杂性,并促进负责任和可持续的投资实践。设计/方法/途径该方法涉及一种动态编程方法,以解决拟议的程序,并假设资产回报为梯形模糊变量。通过这种方法,可以分别用模糊收益的可能平均值和半方差来量化投资组合的收益和风险。基于真实股票市场数据的数值研究检验了所提算法的效率。 研究结果该研究展示了该模型在金融不确定性条件下管理符合伊斯兰教法的投资组合的有效性,并支持在投资决策中纳入道德和可持续性约束的重要性。研究的局限性/意义虽然本文为符合伊斯兰教法的投资组合优化提供了坚实的基础,但也承认该模型的复杂性和计算需求。未来的研究可以在不损害其道德和符合伊斯兰教法原则的前提下探索简化模型。将净化过程和可持续性约束纳入模糊投资组合优化模型是对该领域的独特贡献。

Aishah Binti Tamby Omar, Rasidah Arshad, Rosmah Mat Isa

Purpose

This study aims to examine the relationship between tie strength and poor asnaf student’s normative commitment and its impact on behaviour.

Design/methodology/approach

A sample of 129 poor asnaf students participated in this study. SMART-PLS 3.2.8 was used to analyse the data.

Findings

The findings show that the tie strength dimension (trust, emotional intensity, mutual confiding and relational exchange) positively relates to poor asnaf student’s normative commitment. Also, the result shows that poor asnaf students’ normative commitment is positively related to recipient behaviour.

Research limitations/implications

This study focuses on poor asnaf students receiving zakat financial education aid.

Practical implications

The findings provide valuable information on the factors that encourage poor asnaf students’ normative commitment. Related parties, such as the zakat institution, could use these findings to plan further action to enhance the poor asnaf student’s normative commitment and behaviour.

Originality/value

The study showed that the social tie strength framework could be used to determine the variables affecting poor asnaf student’s normative commitment and behaviour.

目的本研究旨在探讨纽带强度与贫困阿斯纳夫学生规范承诺之间的关系及其对行为的影响。研究结果研究结果表明,纽带强度维度(信任、情感强度、相互倾诉和关系交换)与贫困阿斯纳夫学生的规范承诺呈正相关。研究局限/启示本研究主要针对接受天课资助教育的贫困阿斯纳夫学生。实际意义研究结果为贫困阿斯纳夫学生规范承诺的激励因素提供了有价值的信息。相关方(如天课机构)可利用这些研究结果来计划进一步的行动,以增强贫困天课学生的规范承诺和行为。
