Risk governance and financial stability: A comparative study of conventional and Islamic banks in the GCC

While the linkage between bank governance and financial stability has been discussed widely, empirical explorations of the strength of this relationship are scant. This paper examines the specific role of risk governance in promoting financial stability in banks. Using hand-collected data, it develops a Risk Governance Index (RGI) to measure the strength of risk governance structures and then examines its impact on four main indicators of financial stability for conventional and Islamic banks in the countries of Gulf Cooperation Council (GCC). The results from the dynamic panel models using two-step GMM method suggest that risk governance significantly contributes to the enhancement of the key financial stability measures. The RGI for Islamic banks is found to be smaller than their conventional counterparts and the regression results indicate that risk governance in Islamic banks has a negative impact on stability indicators. While the business models of Islamic banks have features that can enhance stability, poor risk governance can potentially negate this positive feature.     

Investment appraisal practices: A comparative study of conventional and Islamic financial institutions

This paper compares the use of capital budgeting techniques of conventional and Islamic financial institutions, using data obtained from a survey of 105 conventional and Islamic financial institutions. Our main aim is to analyze the use of capital budgeting and risk techniques by the two types of financial institutions from a comparative perspective to see whether prohibition of riba makes a difference. Standard difference-of-means tests of the mean scores methods were used to test the hypotheses of the study. The results reveal a number of important conclusions. First, discounted cash flow techniques are found to be more widely used by financial institutions, and among those techniques internal rate of return is the most common. Second, Islamic financial institutions are found to adopt traditional methods that do not comply with the principles of Islamic Sharia'a. Third, a huge gap is found between the theory base of Islamic institutions and some of the practices of those institutions. Fourth, firms' characteristics, such as size, listing status, sources of revenue and government ownership, have some impact on their decisions to adopt capital budgeting criteria, methods of estimating costs of capital and risk. Finally, the decisions to select particular capital budgeting techniques, cost of capital estimation methods, and risk assessments are partly related to the characteristics of the chief financial officers.     

Payout policy and ownership structure: The case of Islamic and conventional banks

Using a sample of Islamic and conventional financial institutions domiciled in 16 countries for the period 2000–2015, we examine how ownership structure affects dividend policy. Our main findings indicate that ownership identity is important in explaining dividend policy in these banks, albeit in different patterns. In particular, the results suggest that government ownership seems to exert negative effects on dividend payouts in both types of banks, which is in line with the preference of governments towards bank stability. With respect to family ownership, the impact is negative for conventional banks but positive for Islamic ones, consistent with agency theory. These results are to some extent similar in the case of foreign ownership where it is associated with a higher payout policy in Islamic banks, but not significant in conventional ones. Our results are robust to an array of additional analyses including propensity score matching.     

Impact of the global financial crisis on Islamic and conventional stocks and bonds

This study explores the impact of the global financial crisis (GFC) on Islamic and conventional stock and bond indices in 11 Islamic and eight non‐Islamic countries. We find that there are benefits of Islamic stocks during the GFC, particularly during the early stage of the crisis because Islamic institutions are prohibited from holding sub‐prime mortgage securities and derivatives. The strongest benefits of Islamic stocks are in the UK and USA. We conclude that there are benefits of risk reduction and stability for Islamic stocks during a financial crisis, although not necessarily during a global recession.     

Islamic and conventional banks' soundness during the 2007–2008 financial crisis

The recent global financial crisis has induced a series of failure of many conventional banks and led to an increased interest in the Islamic banking business model. This paper attempts to answer empirically the following question: What was the effect of the 2007–2008 financial crisis on the soundness of Islamic banks and their conventional peers? Using the Z-score as an indicator of bank stability, our regression analysis (covering a matched sample of 34 Islamic Banks (IBs) and 34 conventional banks (CBs) from 16 countries) shows that there is no significant difference in terms of the effect of the financial crisis on the soundness of IBs and CBs. This finding reveals that IBs are diverging from their theoretical business model which would have allowed them to keep the same level of soundness even during the crisis.     

Using accounting ratios to distinguish between Islamic and conventional banks in the GCC region

This study determines whether it is possible to distinguish between conventional and Islamic banks in the Gulf Cooperation Council (GCC) region on the basis of financial characteristics alone. Islamic banks operate under different principles, such as risk sharing and the prohibition of interest, yet both types of banks face similar competitive conditions. The combination of effects makes it unclear whether financial ratios will differ significantly between the two categories of banks. We input 26 financial ratios into logit, neural network, and k-means nearest neighbor classification models to determine whether researchers or regulators could use these ratios to distinguish between the two types of banks. Although the means of several ratios are similar between the two categories of banks, non-linear classification techniques (k-means nearest neighbors and neural networks) are able to correctly distinguish Islamic from conventional banks in out-of-sample tests at about a 92% success rate.     

Issues in Islamic Equities: A Literature Survey

This article reviews the current literature on Islamic equities. Our survey indicates that the bulk of articles is quantitative or empirical in nature, with a notable dearth of theoretical works. Among the common research themes explored by these articles are comparative performances of Islamic equities vis-à-vis their conventional counterparts, comparisons of Islamic portfolios with SRI funds, and empirically articulating portfolio diversification benefits associated with Islamic equities. In addition, numerous articles discuss idiosyncrasies of Shari’ah compliant stocks and portfolios under subthemes such as volatility, risk factors, and performance attributes. This survey also includes articles addressing efficiency perspectives, calendar anomalies, and issues in Shari’ah stock screening norms. We summarize general findings and offer suggestions for future research. Literature surveys on Islamic equities are few and far between, and this article, to date, represented the most recent and comprehensive attempt at that.     

Islamic Banking Sustainability: A Review of Literature and Directions for Future Research

This study reviews literature on the Islamic banking sustainability and presents directions for future research. The article discourses scholars’ and practitioners’ views on the two perspectives of sustainability in relation to the objectives of Islamic banking and finance. That there are limited studies on Islamic banking sustainability is one of the major issues presented in the article. The study highlights essential issues on the sustainability without in-depth empirical analysis. The needs for long-term economic, social, and environmental sustainability are not a compromising issue. Therefore, Islamic banks must strike a balance between the institutional, societal, and environmental sustainability in order to achieve the objective of Sharia.     

Using partial least square discriminant analysis to distinguish between Islamic and conventional banks in the MENA region

The deterioration of bank profitability poses a threat not only to the interests of consumers and internal staff members but also affects investors who may equally suffer from significant financial losses. It is important to establish an effective system which assists investors in their investment choices. In prior literature, traditional models have been developed, but achieved short‐term performances such as logistic regression and discriminant analysis. This paper applies a partial least squares discriminant analysis (PLS‐DA) to distinguish between conventional and Islamic banks in the Middle East and North Africa (MENA) region based on the financial information for the period 2005–2011. This method can successfully identify the non‐linearity and correlations between financial indicators. The results demonstrate superior performance of the proposed method. On one hand, our model can select all financial ratios to distinguish between banks and at the same time identify the most important variables in the distinction process. On the other hand, the proposed model has high levels in terms of accuracy and stability.     

Banking efficiency in Gulf Cooperation Council (GCC) countries: A comparative study

We measure cost and profit efficiencies of banks operating in six GCC countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) using heteroskedastic stochastic frontier (HSF) models. Our results show that measures of cost and profit efficiencies of banks vary widely across the six gulf countries over the same period. We examine whether cost and profit efficiencies of Islamic banks are significantly different from that of conventional banks. After allowing for bank risk, asset quality, environmental influences such as the level of interest rate, and country effect, we find that cost and profit efficiencies of Islamic banks are similar to that of conventional banks. Our results suggest that the country-specific variables have significant impact on cost and profit efficiencies of banks operating in GCC countries. Our findings indicate that cost and profit efficiencies of Islamic banks are more volatile than that of conventional banks.     

Shari’ah supervision,corporate governance and performance: Conventional vs. Islamic banks

The performance and accountability of boards of directors and effectiveness of governance mechanisms continue to be a matter of concern. Focusing on differences between conventional banks and Islamic banks, we examine the effect of (i) Shari’ah supervision boards, (ii) board structure and (iii) CEO-power on performance during the period 2005–2011. We find Shari’ah supervision boards positively impact on Islamic banks’ performance when they perform a supervisory role, but the impact is negligible when they have only an advisory role. The effect of board structure (board size and board independence) and CEO power (CEO-chair duality and internally recruited CEO) on the performance of Islamic banks is overall negative. Our findings provide support for the positive contribution of Shari’ah supervision boards but also emphasize the need for enforcement and regulatory mechanism for them to be more effective.     

Modelling bank customer behaviour using feature engineering and classification techniques

This study investigates customer behaviour and activity in the banking sector and uses various feature transformation techniques to convert the behavioural data into different data structures. Feature selection is then performed to generate feature subsets from the transformed datasets. Several classification methods used in the literature are applied to the original and transformed feature subsets. The proposed combined knowledge mining model enable us to conduct a benchmark study on the prediction of bank customer behaviour. A real bank customer dataset, drawn from 24,000 active and inactive customers, is used for an experimental analysis, which sheds new light on the role of feature engineering in bank customer classification. This paper’s detailed systematic analysis of the modelling of bank customer behaviour can help banking institutions take the right steps to increase their customers’ activity.     

Bank image in the UAE: Comparing Islamic and conventional banks

This study investigates how bank customers in the UAE view Islamic banks versus conventional banks and whether this image affects customer loyalties or selection of a bank. We distributed a questionnaire to a convenient sample of UAE bank customers that focused on five areas: bank image, bank products, service quality, cultural aspects and religious factors, in addition to demographic attributes of the sample. The main findings of this study are: first, most UAE bank customers prefer banking with Islamic banks, although they are not satisfied with the quality of products and services; second, customers generally have a positive image of whatever bank they dealt with; third, the regression analysis results indicate that the most important factor in choosing a bank was bank products followed by service quality and then religious factors; fourth, there is a significant difference between how customers perceive UAE Islamic banks versus conventional banks; fifth, there is a significant difference in how customers perceive UAE Islamic banks based on their gender, education and duration of the relationship; and finally, there is a significant difference in how customers perceive UAE conventional banks based on their gender.     

Financial fragility of banks,ownership structure and income diversification: Empirical evidence from the GCC region

This paper investigates the role that ownership structure and diversification of income plays in the financial stability of banks from the GCC region. We find evidence that suggests that higher concentration of ownership in any type of shareholding is associated with higher insolvency risk. However, this higher insolvency risk is not associated with any specific type of shareholders. Higher financial fragility is also associated with the size and whether the bank is an Islamic bank. Banks engaged in substantial fee-based activities are more financially stable as compared with banks that predominantly generate their incomes from traditional intermediation activities.     

A net stable funding ratio for Islamic banks and its impact on financial stability: An international investigation

The Islamic Financial Services Board (IFSB) is the standard setting body for the Islamic banking industry. The IFSB, while endorsing the Basel III accord, modified the criteria to calculate the Net Stable Funding Ratio (NSFR) to cater for the unique aspects of the Islamic banking industry. In this paper, we calculated the modified NSFR of 136 Islamic banks from 30 jurisdictions between 2000 and 2013 and explored the potential impact the requirements of this ratio has on the financial stability of Islamic banks after controlling for bank, country, and market-specific variables. The empirical findings suggest that the modified NSFR has a positive impact on the financial stability of Islamic banks during the sample period. However, the marginal impact of the NSFR on stability diminishes as the size of the bank increases. The results remained robust after applying an alternative measure of stability and using an alternative estimation model based on an instrumental variable approach. These results validate the use of the IFSB’s modified NSFR for Islamic banks as a regulatory measure.     

Hyperbolic distance function,technical efficiency and stability to shocks: A comparison between Islamic banks and conventional banks in MENA region

In this paper, we compare banking performance and resiliency between Islamic banks and conventional banks in MENA region over the period 2002–2014. Stochastic hyperbolic and radial output distance functions are employed to evaluate banking performances. Furthermore, hyperbolic distance function methodology is extended to evaluate bank's business risk through simulations. Historical extreme observed situations in terms of profit loss from the industry are used in order to simulate their impact on the overall profit distribution within the industry. More precisely, we compare the observed profit and the simulated one followed by an abrupt fall in bank lending and non-lending activities. Results find evidence of technical efficiency differences with bank type, some evidence with bank size. It is found that conventional banks are much more vulnerable to an important drop on their lending activities than non-lending activities, while Islamic banks are equally vulnerable to any drop of the activity. Furthermore, Islamic banks are found to be less vulnerable than their counterparts when they are exposed to shocks on their lending activities. Very large banks are much more resilient than small banks whatever is the bank stream. It is also found that bank vulnerability is more important when the banks are not able to adjust their costs in the short run, and increases with the exposure to higher shocks in magnitude.

A shared boundary object: Financial innovation and engineering in Islamic financial institutions

This paper explores the way in which ethico-faith-based rules act as a boundary object in constraining the process of financial innovation and engineering (FIE) in Islamic Financial Institutions (IFIs). The paper examines how this faith-based approach is enacted in the FIE process amid different social worlds and groups that cooperate without consensus within IFIs. We contribute to studies of governance in faith-based organizations, by identifying the plasticity of faith-based rules that act as boundary objects in the governance of the FIE process. The plasticity of ethico-faith based rules allows coordination among local and global actors with intersecting faith-based values, logics, and interests. IFIs ensure that the products of FIE become an integral part of and as compatible as possible with the logics of global financial markets.     

Commercial Banks in the Securities Business: A Review

This paper analyses the potential effects of commercial banks' expansion into the securities business in the context of the contemporary theory of financial intermediation. The analysis focuses on the gains claimed to emerge with that expansion, particularly the gains due to information advantages and economies of scope, and on the costs also claimed to arise with it; namely, those due to conflicts of interest and safety and soundness considerations. The paper ends with a discussion on how these effects depend on the location of the securities unit within the banking conglomerate.
