摘要

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。

Dynamic leverage policy in Islamic and conventional banks during crises in the OIC countries: a procyclicality and prospect-theory analysis

Purpose

The purpose of this study is to investigate and compare the dynamic leverage policies of Islamic and conventional banks within selected Organization of Islamic Cooperation (OIC) countries. The study specifically focuses on the concepts of leverage procyclicality and prospect theory.

Design/methodology/approach

To achieve the research objectives, the study uses data from three distinct periods: Crisis I (2007–2009), Crisis II (2011–2012) and Crisis III (2020). The analysis uses dynamic panel-data regression, using the generalized method of moments (GMM) technique.

Findings

The research findings indicate that both Islamic and conventional banks demonstrate leverage procyclicality. Interestingly, Islamic banks exhibit weaker leverage procyclicality during normal conditions but display stronger procyclicality during crises compared to their conventional counterparts. The application of prospect theory reveals that both bank types exhibit risk-taking or risk-averse behavior through leverage under certain financial and market performance measures as the first-level domain of the gain-vs-loss condition. Furthermore, during crises (as the second-level domain of the normal-vs-crisis condition), both Islamic and conventional banks experience heightened leverage. Notably, Islamic banks, owing to their lower risk exposure and greater shock resilience, demonstrate lesser risk-taking behavior through leverage than conventional banks, both during periods of underperformance and worsening conditions amid crises. These findings validate the extension of prospect theory's applicability in a two-level domain perspective. The dynamic nature of leverage policy, being procyclical and adhering to prospect theory, also varies following different crises specifically.

Research limitations/implications

The study's limitations include the unequal crisis periods (Crises I, II and III), leading to an imbalanced examination of their effects, certain financial and market performance metrics that fail to corroborate the expected hypotheses and the limited generalizability of findings beyond the selected OIC countries.

Practical implications

Understanding the intricate dynamics and behavioral aspects of leverage policy for both Islamic and conventional banks, particularly during crisis scenarios, proves crucial for reviewing banking regulations, making informed financial decisions and managing risks effectively.

Originality/value

This study enriches the current knowledge by presenting two key points. First, it highlights the dynamic nature of leverage procyclicality in Islamic banks, showing a change from weaker procyclicality in normal conditions to stronger procyclicality during crises compared to conventional banks. Second, it expands the application of prospect theory by introducing a dual-level domain context. Examining the comparative leverage policies of Islamic and conventional banks during different crises within OIC countries provides novel insights into leverage procyclicality and behavioral responses.

期刊介绍: The journal provides a dynamic forum for the advancement of accounting and business knowledge based on Shari’ah and Islamic activities that have an impact on the welfare of society. JIABR publishes articles on the interplay between Islamic business ethics, accounting, auditing and governance, in promoting accountability, socio-economic justice (adl) and everlasting success (al-falah). It seeks to inform, among others, current theoretical and empirical research and practice in Islamic accounting, auditing and corporate governance, management of Islamic organizations, accounting regulation and policy for Islamic institutions, Shari’ah auditing and corporate governance, financial and non-financial performance measurement and disclosure in Islamic institutions and organizations. All styles of research, theoretical and empirical, case studies, practice-based papers and research notes that are well written and falling within the journal''s scope, are generally welcomed by the journal. Scope/Coverage Development of accounting, auditing and corporate governance concepts based on Shari’ah Socio-political influence on accounting and auditing regulation and policy making for Islamic financial institutions and organizations Historical perspectives on Islamic accounting, auditing and financial management Critical analysis on issues and challenges on accounting disclosure and measurement, Shari’ah audit and corporate governance Controls and risks in Islamic organizations Financial and non-financial performance measurement and disclosure.
