Purpose

The purpose of this study is to assess and contrast the impact of various factors, including both bank-specific and macroeconomic factors, on the financial performance of Islamic and conventional banks (I&CB) in countries with a dual banking system.

Design/methodology/approach

A general least square model is applied to a large data set of 103 I&CB operating in the Middle East and North Africa (MENA) region, comprising unbalanced annual panel data spanning the period from 2015 to 2020. The financial performance index (FPI) derived from capital adequacy, asset quality, management efficiency, earnings, and liquidity (CAMEL) ratios is used as the dependent variable.

Findings

Key factors, such as overhead expenses, gross domestic product (GDP) and retained earnings, exert a substantial influence on the financial performance of both I&CB. Moreover, the findings suggest that certain parameters, including deposits, inflation and cellular banking usage, significantly impact on the financial performance of conventional banks, while bank size specifically affects the financial performance of Islamic banks.

Research limitations/implications

While this study provides valuable insights, it is essential to acknowledge its limitations. The research focuses on a specific region (MENA) and may not be universally applicable to other geographical areas or banking systems. The study’s findings are based on historical data and might not fully reflect current or future market conditions. Additionally, the choice of variables and methodology may introduce bias or limitations, as with any empirical study. The theoretical implications of the research paper lie in the distinct ethical principles that constitute the foundation of Islamic finance. The ethical opposition to Riba is poised to have extensive implications, influencing market stability, commercial and economic impact and contributing to responsible banking practices within the Islamic banking sector. The study suggests that adherence to these sacred principles not only aligns with ethical considerations but also fosters social responsibility within Islamic banking institutions. This holds significance for broader societal and economic impacts, as responsible banking practices contribute to sustainable and equitable economic development.

Practical implications

The study underscores the significance of efficient overhead cost management for conventional banks, particularly in the context of a rapidly evolving digital banking environment. The call for adaptation and innovation in operational strategies aligns with the broader principles of efficiency and effectiveness emphasized in Islamic finance.

Social implications

In essence, the theoretical and practical implications of the study surpass the narrow focus on financial performance, resonating with the broader societal and economic landscape within the Islamic banking sector. The integration of ethical principles not only reinforces the unique identity of Islamic finance but also positions it as a model for responsible and sustainable banking practices in the MENA region and beyond.

Originality/value

CAMEL ratios are used to build an FPI to evaluate bank performance, providing a more precise and comprehensive assessment compared to traditional return ratios like return on assets or return on equity. Second, the authors conduct a thorough analysis covering factors across bank-specific, financial and macroeconomic dimensions. Thus, the study stands out by not only examining bank-specific factors but also by considering external factors such as GDP, interest rates and the development of the financial sector. The focus on the MENA region allows us to offer generalizable findings, highlighting distinctions between I&CB and considering a period with boom years (2015–2019) and a recession year (2020).
