This paper aims to investigate the differences in mean cost, revenue and profit efficiency scores of conventional versus Islamic banks. It also aims to examine the effect of size and age on cost, revenue and profit efficiency of the sampled banks.

This study evaluates a cross‐country level data compiled from the financial statements of 40 banks in 11 Organisation of Islamic Conference (OIC) countries over the period 1990‐2005. The data were collected for each year available from the BankScope database. The DEA nonparametric efficiency approach originally developed by Farrell was applied to analyse the data.

The findings suggest no significant differences between the overall efficiency of conventional and Islamic banks. However, it was noted that, on average, banks are more efficient in using their resources compared to their ability to generate revenues and profits. The average bank lost an opportunity to receive 27.9 percent more revenue, given the same amount of resources. Similarly, the average bank lost the opportunity to make 20.9 percent more profits utilising the same level of inputs. Clearly there is substantial room for improvement in cost minimisation and revenue and profit maximisation in both banking systems. The size and age factor did not significantly influence the efficiency scores in both banking streams.

This research is substantially different from the prior work in this area in three main ways. First, it investigates cost, revenue, and profit efficiency, whereas previous studies focus on cost, profit, or cost and profit efficiency. Also, no previous studies have compared conventional and Islamic banks. Second, this study distinguishes differences among big versus small, and old versus new banks, which allows more detailed insights on the efficiency issue. Third, the age issue in Islamic banks has been addressed, so far undocumented.

This paper aims to provide a comparative study of the Islamic versus conventional banking sector risk by using market data generated from the sample of publicly listed Islamic and conventional banks in the Gulf Cooperation Council (GCC) region.

The authors introduce a market-based measure of bank stress and test this indicator against the Tier 1 Capital Ratio using Granger causality tests.

The authors find that the market-based measure is a leading indicator of banking stress when compared to the accounting-based Tier 1 ratio and thus is relevant to the Basel regulation’s Pillar 3.

This paper only looks at Islamic vs conventional banks in the Gulf region, and the authors would like to extend this analysis to a broader range of financial institutions, especially in the European and North American markets.

Developing a measure that signals bank stress ahead of typically used measures can help regulators, bank management and investors identify oncoming problems and issues before these become too big to manage.

The results from this analysis provides insight into the offsetting impact from two drivers (beta and book-to-market ratio) of the cost of equity capital for the conventional vs Islamic banking sectors.

This paper aims to examine the effect of state ownership on bank performance for all banks in the Gulf Cooperation Council (GCC) countries during the period 2003 – 2018, for two distinct banking systems: the conventional and the Islamic banking systems.

To achieve the goal of the study, this paper uses a mean t-test to examine the mean difference of the related variables for both banking systems, and a regression test (using the GMM method) to explore the effect of state ownership on bank performance.

The most important result of the analysis is that state ownership has a significantly positive influence on bank performance for conventional banks but not for Islamic banks, in the GCC area.

This study adds to the scarce related literature comparative empirical results with respect to the impact of ownership on the performance of two different banking systems: the conventional system and the Islamic banking system in the GCC area. This study is likely to have implications for policymakers in terms of developing rules relevant to the governance of GCC’s two banking systems that can help to support the stability of the whole banking sector.

Many banking efficiency studies have focused on conventional banks. Recently, Islamic banks have opened in many countries and operated in similar fashion to traditional banks. This chapter measures and compares Islamic banking efficiency to conventional banking efficiency represented by three European countries – Germany, Turkey and the United Kingdom. The study covers the period from 2005 to 2008 in measuring the X-efficiency using the non-parametric method, known as Data Envelopment Analysis (DEA). It reveals that Islamic banks are technically more efficient than conventional banks but are beset by lower allocative efficiency. This results in lower cost efficiency for Islamic banks in comparison to the more conventional banks in Europe.

Purpose – This research analyses the stability of a number of banks operating in Malaysia by using descriptive statistical analysis based on internal variables. These include the characteristics of the bank, capital adequacy ratio, ratio of profitability, liquidity ratio and the ratio of bank operations.

Methodology/approach – Each bank’s stability is studied using z-score analysis. Data are sourced from the balance sheets and income statements of the banks from 2000 to 2011.

Findings – The results indicate that characteristics of a bank do influence a bank’s performance. There are significant differences in financial ratios between Islamic and conventional banking. Islamic banks provide a lower loan loss of capital to cover impaired loans than conventional banks. This provides high capital based on the mean value obtained. The capital ratio allows both sets of banks to meet the capital adequacy ratio set by the Central Bank of Malaysia. Meanwhile, in profitability ratios, conventional banks have higher returns on higher assets, whereas Islamic Banking has higher returns on higher equity. Only 8 Islamic banks and 11 conventional banks are highly stable banking institutions in Malaysia.

Originality/value – Islamic and conventional banking systems in Malaysia need further improvement to deal with unexpected economics crises and increased competition between the two. Hence, Islamic banking must be refined, especially for improving their stability to attract more investments for further development and performance.

The purpose of this paper is to consider borrower-specific characteristics to understand the factors affecting both the probability and quantum of loan default by individual borrowers under Islamic and conventional banking.

Borrower-specific characteristics that explain the probability of default may not necessarily be similar factors that determine the quantum of default. The authors therefore apply a Box-Cox double hurdle model to treat both the probability and quantum of default in a two-step approach. The authors also explain the differences in default risk and quantum of default between Islamic and conventional banking borrowers from their behavioral perspectives following the Sharia principles in financial transactions between lenders and borrowers. The authors use borrower-specific information of two separate bank branches of the United Arab Emirates that solely deal with either Islamic or conventional banking products.

The paper demonstrates that the probability of default and the quantum of default appear to be influenced by different set of client-specific factors. The results suggest that the probability of default does not vary significantly between Islamic and conventional banking borrowers. The evidence also shows that Islamic banking defaulters, compared to those in conventional banking, repay a large quantum of overdue when their financial leverage improves. However, they do not tend to reduce their outstanding quantum of overdue faster than conventional banking defaulters.

Availability of data from only two bank branches may limit the explanatory power of empirical findings.

The study findings will enable the Islamic and conventional banks to appropriately address Basel Capital requirements based on the borrowers’ behavior.

The study findings have the potential for Islamic and conventional financing institutions to be more flexible with equity in their lending practices.

Religious beliefs are crucial in borrower’s default behavior in Islamic banking.

This study aims to investigate the differences in the credit profiles of Islamic and conventional banks in the Gulf Cooperation Council (GCC) region and attempts to identify the factors responsible for those differences.

Financial data sourced from the Bankscope database for a sample of 25 Islamic and 56 conventional banks headquartered in the GCC region between 1987 and 2014 are used. The credit risk of Islamic versus conventional banks is compared using a variety of univariate (mean difference test and correlation analysis) and multivariate tests (pooled ordinary least squares (OLS) regressions with robust standard errors and year fixed effects, regressions with interaction variables and logistic regressions).

Pooled OLS regressions find that Islamic banks have lower credit risk than conventional banks. Robustness checks using logistic functions and interaction variables confirm this result. Using multiple econometric specifications, we also find that higher capitalization, greater liquidity and cost inefficiency contribute to the lower risk profile of Islamic banks.

The study is unable to disaggregate data for banks offering both Islamic and conventional banking services and hence does not include conventional banks with Islamic windows. In addition, there are differences across countries even within the GCC region as to what is considered Sharia’h-compliant and what is not.

The results are of potential interest to not only researchers, but also market participants, regulators and legislators. The methods used in this study could be extended to other two-tiered banking systems and, in the case of Islamic and conventional banking, to other markets.

The authors use a unique sample of banks headquartered in the GCC countries, whose banking markets are similar, if not homogeneous, thus excluding operations of multinational banks. By focusing on the Gulf region, differences in the credit profiles of Islamic and conventional banks can be examined without the confounding effects of unobserved factors like culture, accounting regime or regulatory environment.

The purpose of this study is to evaluate the global developments in the area of fintech solutions by analyzing Islamic and Conventional banks core accounting and market analysis IFIs and their impact on financial inclusion within its core markets.

The authors collect and analyze annual accounting and market Data of the top ten largest Islamic banks and the top ten US Conventional banks, in terms of Total Asset and Market Capitalization, from Bloomberg Data.

The analysis of Bloomberg data shows higher risk-return for Islamic banks–except ROE Market measure that we suggest-than US conventional banks. Nonetheless, Islamic banking grew faster than conventional banking over the period 2006–2021. As a business model, we find that Islamic banks take more credit with more than seventy percent of their profit from loans, while US conventional banks struggle to reach seventy percent interest rate ratio. The authors’ research documents that Fintech and digitalization are driving Islamic finance growth during financial and economic downturns.

FinTech data is not available for banks, further insights of analysis on FinTech and Innovations in the banking sectors.

Islamic banks continuously innovate to satisfy the users of their services and Fintech is opportune to innovation. This study could be interesting for both practitioners and academics wishing to understand and compare Islamic and conventional banking futures.

The authors compared two banking systems, the US and Islamic Banks, which could be useful for users to differentiate between those banking operations.

The authors collected accounting and market data from Bloomberg of top 10 Islamic and top 10 US Conventional banks from 2006 to 2021 to examine Risk-Return, Growth and Business Model of those banks. The authors propose a new Risk-Return measure ROE-Market and its volatility.

This paper aims to empirically assess the contribution of Islamic banks toward the financial stability of Pakistan. For this, the authors investigate the relative financial strength of Islamic banks and their contribution toward the financial stability. They also examine the relationship between the competitive conduct of banks and banking system stability.

The authors use quarterly data of ten conventional banks, four full-fledged Islamic banks and six standalone Islamic branches of conventional banks of Pakistan for the period 2006-2012. The z-score has been computed and used as the measure of stability of banks and the random effects estimator applied to quantify the impact of bank-specific variables and macroeconomic indicators on the financial stability. The empirical framework used in the paper enables the authors us to examine the differential effect of each underlying variable on the financial stability across Islamic and conventional banks. To check the robustness of the results, the authors have estimated several models with different specifications.

The regression results indicate that income diversity, profitability ratio, loan to asset ratio, asset size and the market concentration ratio of banks have significant effects on the stability of banks. Comparing Islamic and conventional banks, notable differential effects of the empirical determinants of financial stability for Islamic and conventional banks have been observed. The results suggest that Islamic banks have performed better as compared to conventional banks and contributed more effectively in the stability of financial sector. Overall, the results depict that the contribution of Islamic banks toward the financial stability has been reasonable and prospective.

The empirical results of the paper are very useful not only for banks’ managements but also for the investors, bank customers and policymakers. Specifically, the findings help in enhancing our understanding as to how the bank-specific variables and macroeconomic indicators are related to the financial stability of the banking system. The results also help understand the role of both Islamic and conventional banks in the financial stability. Further, the results suggest that the financial soundness can be enhanced by creating healthy competition in the banking industry. The results about macroeconomic indicators imply that protective measures are required to intensify (mitigate) the positive (negative) effect of gross domestic product (inflation) on banks’ financial stability.

This paper provides an overall comparative analysis of financial stability of both Islamic and conventional banks of Pakistan. First, the paper computes the z-score for each bank included in the sample, and then, it performs the regression analysis to study how bank-specific variables and macroeconomic factors are related to the financial stability of banks. Unlike the previous studies, our empirical framework enables the authors to examine the differential effect of each underlying variable on the financial stability across Islamic and conventional banks.

The purpose of this paper is to comparatively examine the cost and the overlooked revenue efficiency of Islamic and commercial banks in the aftermath of the crisis, operating in nine MENA-based countries during the 2010-2017 financial period, where the established empirical work is relatively limited. The authors also update the research where they use recent data sets and they provide for a targeted, structured literature review pre- and post-crisis in the Gulf region.

The authors examine cost and revenue efficiency of 25 major Islamic banks (IBs) and 25 major conventional banks (CBs). They conduct tests on the determinants of such variables. In the first stage of the analysis, they measure efficiency by using the data envelopment analysis (DEA) technique. The analysis performs regressions where these also reveal that the bank efficiency index is influenced by various bank type-specific attributes. It also seems that tighter restrictions on bank activities are negatively associated with bank efficiency. Second stage analysis, which accounts for banking environment and bank-level characteristics, confirms these results.

Conventional banks are both more cost and revenue efficient than Islamic banks over the period under examination. The analysis also reveals that the bank efficiency index is influenced by bank-type attributes. Greater presence of fixed capital resources has positive effects on growth in both Islamic and conventional banking. The major constraints impeding Islamic banking growth include labour costs. The authors examine whether and how bank-type orientation affects the cost and revenue efficiency of conventional and Islamic banks. They find that post-crisis Islamic banks underperform their conventional counterparts on both accounts within a mixed banking system.

This study did not include comparative data before the 2008 financial crisis. There is also a great deal of heterogeneity among Islamic banks in the samples that have been examined here and by other researchers and the constructed efficiency scores should be interpreted cautiously as divergent Islamic banks are pooled in the same samples.

This study identified factors that may help bank managers to improve their financial outlook by controlling revenue and cost efficiency profitability. These factors could as well help to understand how some indicators affect both cost and revenue efficiency, particularly in Islamic banking. It also seems that tighter restrictions on Islamic bank activities are negatively associated with bank efficiency. Islamic banks that directly compete with their conventional counterparts in the aftermath of the crisis are less efficient on both the cost and revenue frontiers. They are potentially hindered by the differential regulations of supervising authorities in dual banking systems.

The authors provide recommendations regarding regulatory and other issues that are relevant to Islamic banking and further research is suggested. Findings are relevant to a variety of stakeholders (managers, policymakers and regulators). Islamic banking authorities could re-examine the benefits of partially moving to a more standardized/conventional system of banking by lifting some trading restrictions. In addition, developing and maintaining managerial skills is an indispensable instrument for the long-term endurance of any system. A related aspect is thus an effort to determine the holistic efficiency (including managerial) of Islamic banks as a guide for policymakers to improve managerial performance.

There is relatively limited empirical work that investigates the efficiency between Islamic and conventional banking in the aftermath of the crisis in the Gulf region despite the growing importance of this region on political and economic levels. The authors also examine the revenue efficiency measure often under-researched in the literature and particularly important for comparative studies. Overseas-owned banks have attained much higher infiltration levels in middle-eastern countries over the past decade. It has also been suggested that market penetration differences may also be related to bank efficiency concerns among countries and their financial systems as opposed to types of banks.
