Dual market competition and deposit rate setting in Islamic and conventional banks

This paper addresses the issue of competition in dual banking markets by analyzing the determinants of deposit rates in Islamic and conventional banks. Using a sample of 20 countries with dual banking systems over the 2000–2014 period, our results show significant differences in the drivers of Islamic and conventional banks' pricing behavior. Conventional banks with stronger market power set lower deposit rates but market power is not significant for Islamic banks. In predominantly Muslim environments, conventional banks set higher deposit rates and further higher when their market power is lower. Whereas conventional banks are influenced by the competitiveness of Islamic banks, Islamic banks are only affected by their peers in predominantly Muslim countries. Our findings have important implications regarding competition and bank stability in dual banking markets.     

Are Islamic Banks More Resilient During Financial Panics?

Islamic banking is one of the fastest growing segments of the financial sector in developing countries. Rapid growth of this segment is accompanied with claims about its relative resilience to financial crises as compared to conventional banking. However, little empirical evidence is available to support such claims. Using data from Pakistan, where Islamic and conventional banks co‐exist, we compare the behaviour of Islamic and conventional banks during a financial panic. Our results show that Islamic bank branches are less prone to deposit withdrawals during financial panics, both unconditionally and after controlling for bank characteristics. The Islamic branches of banks that have both Islamic and conventional operations tend to attract (rather than lose) deposits during panics, which suggests a role for religious branding. We also find that Islamic bank branches grant more loans during financial panics and that their lending decisions are less sensitive to changes in deposits. Our findings suggest that greater financial inclusion of faith‐based groups may enhance the stability of the banking system.     

Impact of interest rates on Islamic and conventional banks: the case of Turkey

Identifying the impact of the interest rates upon Islamic banks is a key to understand the contribution of such institutions to the financial stability, designing monetary policies and devising a proper risk management applicable to these institutions. This article analyses and investigates the impact of interest rate shock upon the deposits and loans held by the conventional and Islamic banks with particular reference to the period between December 2005 and July 2009 based on Vector Error Correction (VEC) methodology. It is theoretically expected that the Islamic banks, relying on interest-free banking, shall not be affected by the interest rates; however, in concurrence with the previous studies, the article finds that the Islamic banks in Turkey are visibly influenced by interest rates.     

Business cycle and bank lending procyclicality in a dual banking system

The paper studies bank lending behaviour over the business cycle in a dual banking system, Malaysia, with the objective of ascertaining whether Islamic banks have a role in stabilizing credit. The study makes use of unbalanced panel data of 21 conventional banks and 16 Islamic banks covering mostly the period 2001–2013. Applying dynamic GMM estimators, we find the aggregate loans by banks to be pro-cyclical in conformity with existing studies. However, when we segregate the lending/financing behaviour of conventional and Islamic banks, the cyclicality of bank lending seems to be true only for conventional banks. As for the Islamic banks, the business cycle does not seem to affect their financing decisions. Indeed, there is indication that the Islamic banks in general and the full-fledged Islamic banks in particular can even be counter-cyclical in their financing decisions. This conclusion is fairly robust to a different loan measure, alternative model specifications, and to an alternative business cycle measure. Hence, our results provide further support to the “stability” view of the Islamic banks in that they have the ability to stabilize credit.     

Small business lending and credit risk: Granger causality evidence

Because of their opaque nature, SMEs are overly reliant on bank lending. Therefore, we examine whether banks' credit supply to SMEs are affected by their financial conditions. To this end, we employ a Granger causality analysis to examine whether there is an indication of a significant direction of determination between SME lending and non-performing SME loans. The results reveal no bidirectional relationship between SME lending and NPL for the entire banking sector. For Islamic banks, however, we find two-way linkages between these two parameters: a negative causation is running both from SME lending to NPL growth and from NPL to SME lending. Given Islamic banks' deposit-oriented funding practices and their adherence to profit-and-loss sharing principles, this finding suggests the presence of heightened market discipline within the Islamic banking system.     

The dependency of Islamic bank rates on conventional bank interest rates: further evidence from Turkey

The nexus between Islamic banks’ returns on term deposits (participation accounts) and conventional banks’ (CBs) interest rates on term deposits is one of the controversies with regard to Islamic finance. The obvious correlation between two sides is considered a convergence of Islamic banking to the conventional mode and the breach of the ‘risk sharing’, the underlying principle of Islamic finance. The aim of this study is to econometrically investigate the long-term relationship between CBs’ term-deposit rates (TDRs) and participation banks’ (PBs) TDR in Turkey. We undertake an elaborate analysis of the dependency of each PBs in Turkey on interest rates utilizing the most recent econometric techniques including Maki cointegration tests with multiple breaks and frequency domain causality tests. Findings show that TDRs of three PBs are significantly cointegrated with those of CBs, while one is not. In addition, permanent causality is found from CBs to all PBs.     

Religiosity versus rationality: Depositor behavior in Islamic and conventional banks

This study investigates the behavioral aspects of Islamic bank depositors in a dual banking system. By categorizing depositors into groups based on the amount of their deposited funds, we estimate the responses of these groups to interest rate changes. We take the findings of conventional banks as a comparative baseline and investigate the extent to which the changes in different Islamic depositor groups differ from conventional depositor groups. The findings show that depositors in both Islamic and conventional banks respond to interest rate changes. The analysis indicates that Islamic bank depositors are more responsive when their deposit sizes are larger. When Islamic bank depositors’ opportunity costs rise due to a rise in the interest rate, they do not hesitate to withdraw deposits. The relation between interest rate changes and deposits is more robust in Islamic banks than in conventional banks.     

Risk management and dynamic network performance: an illustration using a dual banking system

This study applies dynamic network data envelopment analysis to compare a dual banking system, namely conventional and Islamic banks, with emphasis on risk measures. Non-oriented, variable return-to-scale dynamic network slacks-based measure is used to model the banking performance for the period 2008–2012. Under the consideration of risk measures, the findings highlight that Islamic banks excel in managerial efficiency while conventional banks surpass in profitability efficiency. Furthermore, the regression results find that the number of directors on the risk management committee has a positive impact on banking performance. Meanwhile, the high number of independent directors improves the profitability efficiency but worsens the managerial efficiency.     

BANK PERFORMANCE,FINANCIAL STABILITY AND MARKET CONCENTRATION: EVIDENCE FROM COOPERATIVE AND NON‐COOPERATIVE BANKS

Relying upon highly territorially disaggregated data taken at labour market areas, the paper explores the relationship between bank performances and financial stability of the banking system taking into account the role of market concentration. The z‐score is used as financial stability indicator, while the performance of financial intermediaries is measured using a parametric method recently developed (Kumbhakar et al. 2014). The empirical evidence shows a positive relationship between bank performance and financial stability and supports the ‘concentration–stability’ view for non‐cooperative banks only when concentration is measured on the whole sample of banks. Differences in the performance–stability nexus seem to depend more on the type of banks rather than different levels of market concentration. Higher market concentration of cooperative banks affects systemic stability by reducing the z‐scores of non‐cooperative banks, supporting the hypothesis that the presence of non‐profit‐maximizing entities can pull down stability of other financial institutions.     

Activity strategies,information asymmetry,and bank opacity

Using a large panel of US bank holding companies from 2001 to 2015, we investigate the association between functional diversification and bank earnings management. We document a positive relationship between bank earnings management and bank diversification. Our findings are consistent with the hypothesis that diversification increases the asymmetric information of banks, leading to greater discretionary power by bank managers. This effect is most prevalent in smaller banks and non-dividend paying banks. The impact of diversification on earnings management is less pronounced during the crisis. Our study is of interest to regulators and other stakeholders who examine factors which affect behavior of bank managers.     

Does a one-size-fits-all approach to financial regulations alleviate default risk? The case of dual banking systems

Financial regulations are developed to curb financial and economic fragility costs without undermining the economic contributions of banks to economic development. To understand the impact financial regulations have on reducing the financial fragility of banks we use the probability-of-default of banks as a proxy for bank failure. After analyzing data collected from 15 countries with a dual banking system for the period 2000–2015, we find convincing evidence that not all financial regulations have risk-reducing benefits for banks and the impact of financial regulations on default risk is not the same for conventional banks (CBs) and Islamic banks (IBs). The empirical evidence suggests that regulations that lessen overall default risk have a greater impact on IBs while those increasing default risk have a greater impact on CBs. Based on our findings we recommend that regulators should consider the different natures of CBs and IBs and tailor financial regulations to suit these operationally distinct financial intermediaries.     

Performance and productivity in Islamic and conventional banks: Evidence from the global financial crisis

We assess the performance and productivity of Islamic and conventional banks using financial ratios, a two- and a four-component meta-frontier Malmquist productivity index (MPI). We focus on the relatively homogenous GCC region over the 2006–2012 period that covers the global financial crisis. We find that Islamic banks exhibit worse cost and profit performance but are on a par with regards to revenue performance compared to the conventional ones. The components of the meta-frontier MPI suggest that the technology of conventional banks improves markedly in years leading to the financial crisis and declines thereafter. Islamic banks show a similar but more muted pattern. By contrast, the pronounced within-Islamic bank group variation in technical efficiency and technology suggests that Islamic banks are quite heterogeneous as a group. Overall, the MPI analysis suggests that the two bank types are more aligned following the global financial crisis. Policy makers should be wary of the important variations within the Islamic banking industry when implementing bank regulations.     

Democracy,regulation and competition in emerging banking systems

This paper develops a political economy framework to analyse the relations among democracy, financial regulation and banking competition in the emerging banking systems of Central and Eastern Europe. We develop extensive new yearly non-structural indices of bank competition instead of concentration indices as in the previous literature that show its evolution over time with the level of democracy. In addition, we directly test for linkages between democracy, financial regulation and banking competition. Using an unbalanced panel data set over the period 1994–2016 for 617 banks, we show that more democratic countries with better regulatory framework lead to the enhancement of competition. We also find significant support for the core hypothesis that financial regulatory framework in a “partially” democratic environment is inadequate. Given that financial regulatory framework in a “partially” democratic environment can be inadequate we find a U-shaped relation in the sense that there is a threshold level of democracy beyond which banking systems in those countries are more competitive.     

Bank overall financial strength: Islamic versus conventional banks

A number of recent studies compare the performance of Islamic and conventional banks with the use of individual financial ratios or efficiency frontier techniques. The present study extends this strand of the literature, by comparing Islamic banks, conventional banks, and banks with an Islamic window with the use of a bank overall financial strength index. This index is developed with a multicriteria methodology that allows us to aggregate various criteria capturing bank capital strength, asset quality, earnings, liquidity, and management quality in controlling expenses. We find that banks differ significantly in terms of individual financial ratios; however, the difference of the overall financial strength between Islamic and conventional banks is not statistically significant. This finding is confirmed with both univariate comparisons and in multivariate regression estimations. When we look at the bank financial strength within regions, we find that conventional banks outperform both the Islamic banks and the banks with Islamic window in the case of Asia and the Gulf Cooperation Council; however, Islamic banks perform better in the MENA and Senegal region. Second stage regressions also reveal that the bank overall financial strength index is influenced by various country-specific attributes. These include control of corruption, government effectiveness, and operation in one of the seven countries that are expected to drive the next big wave in Islamic finance.     

Conventional and Islamic Banks’ Performance in the Gulf Cooperation Council Countries; Efficiency and Determinants

This paper investigates the cost efficiency levels of the banking sectors of the Gulf Cooperation Council (GCC) countries for the period from 2001 to 2015 and provides a comparison of conventional and Islamic banks. We obtain measures of efficiency using a stochastic frontier model and the meta-frontier approach. The evidence demonstrates that Islamic banks are less efficient and have a weaker level of production technology than conventional banks. The cost efficiency of banks varies significantly across the six Gulf countries and over time. We adopt the results drawn from the meta-frontier model that allow to take into account the differences between the studied countries, and empirically examine the bank-specific, financial, macroeconomic, and political determinants of banking efficiency. The results provide evidence of the differential effects of the selected variables on the efficiency of conventional and Islamic banks. These variables affect the performance of the two types of banks in different ways and with different magnitudes.

     

Financing Channels and Monetary Policy in a Dual Banking System: Evidence from Islamic Banks in Indonesia

Using Indonesian Islamic banking data from 2003 to 2014, this article employs a panel regression methodology to investigate the responses of Islamic banks to changes in financing rates and monetary policy, which may differ depending on their characteristics. The results suggest that the financing rate has a negative impact on financing at Islamic banks, while bank‐specific characteristics have a positive influence on it. The size and amount of capital have a greater impact than liquidity on financing at Islamic banks. However, changes in monetary policy are insignificant on bank financing, which implies that the transmission of monetary policy through the Islamic segment of the banking sector is weak. Furthermore, the weak impact of monetary policy on bank financing can be explained by the dramatic expansion of Islamic banks during the sample period, which contributed to a substantial increase in deposit growth and a high liquidity position.     

Tail dependence risk exposure and diversification potential of Islamic and conventional banks

This paper undertakes a rolling window comparative analysis of risks for portfolios consisting of GCC Islamic and conventional bank indices. We draw our empirical results by employing canonical, drawable and regular vine copula models, as well as by implementing a portfolio optimization method with a conditional Value-at-Risk constraint. We find evidence of higher riskiness in the group of Islamic banks relative to the group of conventional banks across each of the financial rolling window scenarios under consideration. Specifically, a greater negative (nonlinear) tail asymmetric dependence is observed in the pairs of Islamic banks’ relationships. The results also show that the optimal portfolio model supports a clear preference towards the group of conventional banks in regard to risk minimization and diversification benefits.     

A new approach to measuring universal banking

Noninterest income is widely used in the literature to account for the degree of the universal business model by banks. This paper proposes a novel measure of universal banking constructed using the relative contribution of each operating segment to total assets using an entropy approach. We here propose a novel dataset containing the Universal Banking Index (UBI) at both country and bank levels. Using a sample of international banks, we evaluate the extent to which our proposed metric affects banks’ profitability, stability, liquidity and capitalisation. Results suggest that a higher degree of diversification is associated with increased stability. In addition, banks that feature a more diversified business model, as proxied by the UBI, are also better capitalised, as opposed to banks with high noninterest income share. Our results suggest that regulatory-induced restriction on universal banking may indeed reduce the benefits of risk sharing across operating segments, exposing banks to heightened risks.

Foreign Banks and Credit Volatility: The Case of Latin American Countries

The number of foreign banks in Latin America increased substantially over the period 1995–2001, prompting a debate on the potential consequences for host countries. Discussions focused on efficiency, the impact on competition and product market diversification in the banking industry, and the quality of the regulatory environment, among other issues. Against this background, this paper uses ARCH techniques to test the impact of foreign banks on both the level and the volatility of real private bank credit in a panel of eight Latin American countries, using quarterly data over the period 1995–2001. The empirical findings show that, together with financial development, the presence of foreign banks has contributed to reducing real credit volatility, improving the buffer shock function of the banking sector.
