The purpose of this paper is twofold. First, it attempts to determine the factors that influence the stability of Islamic and conventional banks. Second, it focuses on the relationship between the regulatory capital and bank soundness.

Thus, the authors use the Z-score to assess the stability of Islamic and conventional banks operating in the Middle East and North Africa region over the period 1999 to 2014.

The comparative analysis reveals that Islamic banks seem to be less stable than their conventional peers. With regard to the determinants of bank stability, the findings suggest that the regulatory capital represents the primordial factor that reinforces the soundness of banking systems. The authors also find that bank stability depends on both bank-specific variables as well as macroeconomic and institutional variables. Interestingly, the corruption level turns out to have a significant negative effect on financial strength in the both types of banks.

The authors believe that investigating the relationship between regulatory capital and the failure risk in a comparative study between Islamic and conventional banks deserves a particular attention and looks very interesting because it will allow them to identify the difference between the factors explaining the failure risk of each type of banks. The authors also believe that the analysis of the relationship between corruption and bank stability is very interesting because corruption can be seen as an example of moral hazard which forces Islamic banks to use non-PLS instruments.

The distinctive feature of Islamic financial intermediation is its foundation on profit-and-loss sharing which reinforces solidarity and fraternity between partners. Thus, the bank margin and its determinants may differ between Islamic and conventional banks (CBs). The purpose of this paper is to empirically assess the main factors that explain the bank margin in a panel of Islamic and CBs operating in the Middle East and North Africa (MENA) region. This study will permit to identify the common and the specific determinants of the intermediation margins in dual banking systems.

The authors use a dynamic panel approach. The empirical analysis is carried out for a sample of 50 Islamic banks (IBs) and 126 CBs from 14 MENA countries.

The results reveal that net profit margins of IBs may be explained for the most part by risk aversion, inefficiency, diversification and economic conditions. With regard to CBs, their margins depend positively on market concentration and risk aversion and negatively on specialization, diversification, inefficiency and liquidity.

The significant impact of the degree of diversification on margins suggests that any policy analysis of the pricing behavior of banks should rely on its whole output. The high levels of margins in Islamic and CBs based in the MENA region may represent an obstacle to these countries to pursue their development process. Thus, policy makers in these countries should consolidate the role of capital markets and nonbanking financial institutions to provide alternative sources of funding and stimulate more competition.

The positive relationship between concentration and net interest margins requires that policy makers should create competitive conditions if they want to lower the social cost of financial intermediation. The creation of competitive conditions may be achieved through encouraging the establishment of new domestic banks or the penetration of foreign banks.

The present study aims to contribute to the existing literature on the determinants of bank margins in three ways. First, the authors identify the factors that most explain bank margins for both conventional and IBs. The majority of previous studies examine the determinants of the profitability or the overall performance of banks and in particular conventional ones. Second, this paper employs two generalized method of moments (GMM) approaches introduced by Arellano and Bover (1995) and Arellano and Bond (1991). It differs from Hutapea and Kasri (2010) who employed the co-integration technique to examine the long-run relationship between Islamic and CB margins and their determinants in Indonesia. Third, unlike previous studies focusing on MENA region that use a small number of countries and a short sample period, the period of study covers 16 years from 1999 to 2014 and a large sample of countries (14 countries). This paper differs from Lee and Isa (2017) who applied the dynamic two-step GMM estimator technique introduced by Arellano and Bond (1991) to study the determinants of intermediation margins of Islamic and CBs located in Malaysia.

This study aims to examine the impact of market competition, and capital regulation on the cost of financial intermediation of banks of the Bangladesh banking industry.

This study has used a balanced panel dataset comprised of 340 firm-year observations for 34 commercial banks in the Bangladesh banking industry from 2011 to 2020. The Prais Winsten panel estimator has been used to assess the impact of market competition and capital regulation on the cost of financial intermediation of banks.

Based on the regression results, this study has documented that greater market competition results in a lower cost of financial intermediation for banks. Similarly, an increase in the regulatory capital of banks increases the cost of financial intermediation of banks. The main findings of this study are found robust by using alternative proxies for the cost of financial intermediation, market competition and capital regulation. The regression results also suggest that private commercial banks tend to have a higher cost of financial intermediation than state-owned commercial banks.

The regulatory reforms should aim to foster sustainable and optimal market competition for the Bangladesh banking industry to regulate the market power of banks to reduce the cost of financial intermediation. The regulatory authority of Bangladesh should find the optimal policy measures for implementing the capital regulation in the banking industry which would reduce the cost of financial intermediation margin of banks.

Unlike previous studies which have used structural market competition measures, this study has used non-structural market competition measures to assess the relationship between market competition and cost of financial intermediation in the Bangladesh banking industry.

The purpose of this paper is to examine the determinants of bank margins in the Yemeni banking sector for Islamic and conventional banks. The first objective is to investigate whether there is a significant difference between the margins of conventional and Islamic banks. The second objective is to examine whether efficiency represents an influential factor in determining bank margins for Islamic and conventional banks controlling for other micro and macro variables.

Using a data set of banks in Yemen for the post-liberalisation period from 1996 to 2011, the study utilises panel data with unbalanced observations for 16 banks, of which four are Islamic banks and the remainder conventional banks. Parametric and non-parametric techniques are complemented by dummy variable regression using random effects. Panel fixed effects regression was also undertaken as a robustness check.

The paper finds that the overall bank margin in Yemen has steadily decreased during the observation period with the exception of the year 2011. The parametric and non-parametric results show that the bank margins are significantly higher for conventional banks than for Islamic banks. The results provide evidence that bank margins are related to neither types of efficiency, but are affected by capitalisation, size, the opportunity cost of the reserve and liquidity, although the impact is shaped differently for Islamic and conventional banks.

The paper provides a basis for regulators and bankers for assessing the viability of the banking sector and proposes policies to restructure the industry to enhance its performance.

This paper adds value to the literature for the Yemeni banking sector and extends the previous research on the determinants of bank margins by focusing on the impact of efficiency on bank margins. Also, it compares the Islamic banks with different types of conventional banks in Yemen in their margins trend.

The purpose of this paper is to conduct a comparative analysis of internal and external determinants of bank’s performance in Middle East and North Africa (MENA) countries.

The authors use a static unbalanced annual panel data of banks operating in eight countries pertaining to the MENA region (Tunisia, Bahrain, Egypt, Jordan, Qatar, Lebanon, Kingdom of Saudi Arabia and United Arab Emirates) over the period from 1999 to 2014.

The findings reveal that the determinants of intermediation margins in the MENA region differ across countries. Overall, banks interest margins are explained by both bank-specific variables and macroeconomic factors except for Saudi Arabia in which interest margins exclusively depend on bank-specific factors.

These findings contribute to the clarification and critical analysis of the current state of bank’s performance in some countries located in MENA region, which would have several crucial policy implications.

This study investigates the determinants of net interest margin (NIM) and tests the decoupling hypothesis in Turkey's Islamic and conventional banks.

This study has employed a panel quantile model (PQM) to assess the net interest margin (NIM) and test the decoupling hypothesis in the dual banking system of Turkey.

The empirical results show that the impact of equity is positive for both Islamic and conventional banks but relatively more robust for Islamic banks. Moreover, it is observed that return on assets has a positive association with NIM in both types of banking systems. Interestingly, the impact increases from lower to higher quantiles, but a higher acceleration rate is observed for Islamic banks. The study also finds that, as bank stability increases, NIM decreases for both groups of banks but more stably for Islamic banks, resulting in lower margins than conventional banks. Thus, the paper confirms the decoupling hypothesis and suggests that, to increase profit margins, Islamic banks need to increase assets and equity.

The paper confirms the decoupling hypothesis and suggests that to increase profit margin, Islamic banks need to increase assets and equity.

Since both equity and assets contribute positively to interest margins, policymakers in the industry need to increase the size of equity and assets to get maximum returns.

This is one of the first studies to investigate NIM's determinants and test the decoupling hypothesis in the Turkish dual banking system using a non-parametric MCMC panel quantile regression (QRM) model.

The purpose of this paper is to analyze the impact of macroeconomic‐industrial and bank‐specific factors on Latin American banks’ performance.

Using the data panel system estimator version of the generalized method of moments, the authors estimate the determinants of return on assets and interest margin for a sample of 78 commercial banks from Argentina, Brazil, Chile, Colombia, México, Paraguay, Peru, and Venezuela over the period from 1995 to 2010.

On the one hand, the results show that bank performance is positively related to both idiosyncratic factors, such as service diversification, size, capital ratio, and specialization degree, and to macroeconomic‐industrial factors such as economic growth, inflation, and bank concentration. On the other hand, the results show that bank performance is negatively related to credit risk, liquidity risk, and operational inefficiencies.

The authors provide new evidence from the Latin American bank industry and incorporate the effect of diversification through noninterest activities.

The purpose of this paper is to analyzes how board’s gender diversity, and more specifically a gender-balanced configuration – i.e. a proportion of women in the boardroom ranging between 40 and 60 percent – affects economic and risk-oriented performance in financial firms.

The empirical application uses a rich data set that includes detailed accounting and organizational information for all financial firms in the Costa Rican industry during the period 2000–2012. The proposed hypotheses are tested using panel data (fixed-effects) regression models that emphasize that bank performance is affected by various dimensions of the banks’ gender diversity.

The longitudinal analysis of the Costa Rican banking industry reveals that, unlike a proportion indicating a particular critical mass of women on the board, a balanced gender configuration yields superior economic performance (ROA and net intermediation margin). Additionally, the findings show that the performance benefits of gender diversity only exists in the presence of a gender-balanced board configuration, and that this positive effect is not conditioned by the presence of women leadership in the corporate hierarchy (Chair or CEO).

The paper further explores the influence of board gender diversity on organizational performance by adopting an approach to the gender diversity–performance relationship that goes beyond the mere representation of women within the corporate hierarchy.

The paper investigates the interest rate policy transmission mechanism and the role of market structure of the banking industry in Qatar.

Competitiveness indexes are used to measure the degree of market power in the banking industry in Qatar. The momentum threshold autoregressive model is applied over the monthly period from January 2005 to June 2018 to examine the magnitude of intermediation and adjustment to disequilibria in the deposit market. In addition, to model interest rate volatility and overcome the problem of heteroscedastic errors in the error correction standard models, an asymmetric EC-EGARCH-M model is applied.

The findings suggest incomplete pass-through and asymmetric response to monetary shocks. The asymmetric adjustment mechanism is found to be downward rigid which suggests a high degree of customer sophistication and an elastic supply of deposits. The results of the EC-EGARCH-M show that the impact of monetary policy shocks has a significant positive impact on deposit interest rates and that negative monetary shocks trigger more conditional interest rate volatility in the next period than positive monetary shocks for a short maturity rate.

The paper is the first to highlight the behaviour of the interest rate pass through channel and measures the degree of competitiveness of the banking industry for the case of a small, rich country. In addition, using recent data, the paper applies different econometric methodologies and overcomes the problem of heteroskedastic errors by modelling the interest rate volatility using the EC-EGARCH-M model.
