Market power versus efficiency under uncertainty: conventional versus Islamic banking in the GCC

In this article we estimate the effect of concentration on intermediation margins in Gulf Cooperation Council's (GCC) Islamic and conventional banking under the assumption that margins are uncertain. The empirical model, which we formally derive from an expected utility maximization problem, allows us to test for risk aversion as well as competitive conduct in loan and the deposit markets. The model also yields an expression showing that the effect of concentration on margins is the sum of its respective effects on market power, marginal cost of intermediation and marginal cost of uncertainty. The expression allows us to test whether concentration is welfare enhancing, reducing or neutral. We find Islamic banks to be risk-averse and conventional banks to be risk-neutral. We also find that concentration is welfare-neutral in Islamic loans and deposits, welfare-enhancing in conventional loans and welfare-neutral in conventional deposits. We used Nonlinear Two-Stage Least Squares (N2SLS) and Nonlinear Three-Stage Least Squares (N3SLS) to check for robustness.     

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.     

Bank competition, financial reform, and institutions: The importance of being developed

In this paper, I estimate the degree of market power at the bank-level for 84 banking systems worldwide. Subsequently, I analyze the sources of bank competition, placing emphasis on the impact of financial reform and the quality of institutions. I find that financial liberalization policies reduce the market power of banks in developed countries with advanced institutions. In contrast, banking competition does not improve at the same pace in countries with weaker institutions and a lower level of institutional development. The results hold across a wide array of identification tests and estimation methods. The main policy implication to be drawn is that a certain level of institutional development is a precondition for the success of reforms aimed at enhancing the competition and efficiency of banking markets.     

Intricacies of competition,stability, and diversification: Evidence from dual banking economies

This paper investigates the nexus of competition and stability by introducing the interaction of diversification and competition. We use a sample of both conventional and Islamic banks from 14 dual banking economies over 2005–2016. The core finding illustrates that competition does not impact bank stability and that diversification is insignificant in the competition-stability nexus. Further, we find that concentration is beneficial for the banking stability of both types of banks. In most of our results, we found no difference in the impact of competition and diversification on the stability of conventional and Islamic banks. To put our findings in a broader context, we argue that no difference between the business models can be considered an early signal of possible convergence between the two systems.     

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.     

Microeconomic determinants of acquisitions of Eastern European banks by Western European banks1

A considerable number of Western European banks acquired banks in Central and Eastern Europe from the mid‐1990s onwards. The question is whether or not this will improve the efficiency and profitability of the Central and Eastern European banking sectors. We test the relative strength of the efficiency versus the market power hypotheses by investigating the bank‐specific characteristics of the banks involved in the cross‐border acquisitions. We also examine the determinants of the post‐acquisition target banks’ performance. Our results indicate that large Western European banks have targeted relatively large and efficient Central and Eastern European countries (CEEC) banks with an established presence in their local retail banking markets. We find no evidence that cross‐border bank acquisitions in the CEEC are driven by efficiency motivations. The evidence supports the market power hypothesis, raising concerns about the optimal balance between foreign ownership and competition.     

The size distribution of the banking sector and the effects of monetary policy

In recent years, the industrial organization of the banking system has received a large amount of attention. In particular, it is generally viewed that the size distribution of the banking sector has changed where it is dominated by a small number of large institutions. In this paper, we develop a model of imperfectly competitive banks that differ in terms of the size of their deposit base. Such differences are important for aggregate credit market activity and the effects of monetary policy. Notably, we explain how the optimal size distribution of the banking system involves trade-offs from distortions in credit markets due to imperfect competition across banking markets. Second, the effects of monetary policy on credit market activity are weaker in an economy dominated by a small number of large banks. Empirical analysis examining the role of concentration among the current members of the European Monetary Union is consistent with the predictions of the model.     

Market power and risk of Central and Eastern European banks: Does more powerful mean safer?

As understanding the market power–risk relationship in CEE banking systems is of the utmost importance to policy-makers in these countries, we investigate whether CEE banks must have greater market power to be safer. Our results suggest that more market power reduces the fragility of banking institutions, on one hand, and that banking market concentration tends to make these banks riskier, on the other. Our findings are robust to whatever form of market power-risk relationship and whatever market-power measures we use. More precisely, financial markets perceive CEE banks with more market power as less fragile, while the latter are also better capitalised with respect to the distribution of their returns. Moreover, they are even (much) better capitalised when they hold less-diversified and less-liquid assets and when they operate within a stricter banking regulatory environment, which suggests a risk-stabilising role for diversification, liquidity and the bank regulatory environment in these countries.     

Determinants of Interest Rate Pass-through for Emerging Market Economies: The Role of Financial Market Structure

It is essential for central banks to assess whether or not the pass-through from monetary policy rates to credit and deposit interest rates is complete in order to ensure price stability. In this article, we analyze interest rate pass-through process for emerging market economies. Since emerging market countries lack large panel data sets that are typically available for developed countries, it is hard to analyze the determinants of pass-through coefficients for emerging market countries. To overcome the data issue, we developed a country selection procedure that minimizes heterogeneity among the countries included in the analysis. Our findings indicate that banking sectors?? competition plays a more important role for emerging market countries than their developed counterparts.     

How Islamic are Islamic banks? A non-linear assessment of Islamic rate – conventional rate relations

In this paper, we perform a non-linear assessment of Islamic rate – conventional rate relations for the case of Malaysia. Using monthly data covering the period January 1999 to November 2016, we find strong evidence supporting non-linear reactions of the Islamic investment rates to conventional rates in the long run and/or short-run for all matched maturities. More precisely, the Islamic investment rates exhibit faster upward movement (slower downward movement) in responses to conventional deposit rate increases (decreases). The asymmetric pricing behaviour of Islamic banks however tends to weaken as maturity lengthens. Accordingly, we infer that Islamic banks do not rigidly peg their investment deposit rates to conventional deposit rates as some have claimed in questioning the Islamicity of Islamic banks.     

Convergence of bank competition in Central and Eastern European countries: do foreign and domestic banks go hand in hand?

Following the massive entry of foreign banks into the Central and Eastern European (CEE) banking markets, one may wonder whether their competitive behaviour differs from that of their domestic counterparts, possibly leading to the segmentation of these markets at the regional and national levels. We find that the competitive behaviour of foreign and domestic banks differs, with foreign banks having less market power until the recent financial crisis and more market power after this financial turmoil. Despite this difference, banks tend to behave similarly, and their market power converges to a similar level. The tendency towards similar competitive behaviour is observed at the regional and national levels and for both foreign and domestic banks, although foreign institutions that enter these markets through the acquisition of domestic banks have slightly more market power. Our findings suggest the regional integration of CEE banking markets and no segmentation between foreign and domestic institutions.     

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.     

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.     

Exploiting old customers and attracting new ones: The case of bank deposit pricing

Recent theoretical contributions suggest that deposit interest rates should be higher in geographic areas characterized by greater in-migration and lower for depositors at banks with greater shares of existing (or so-called “locked-in”) depositors. These hypotheses are tested using a rich data set obtained for the Spanish banking industry. Results confirm that, all else equal, banks offer higher deposit rates in territories characterized by greater in-migration, and also that they tend to offer lower rates, the larger the number of their locked-in depositors. These findings confirm the existence of the trade-off between exploiting old customers and attracting new ones.     

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.     

Tipping the (Im)balance: Capital inflows,financial market structure,and banking crises

An emerging consensus among scholars and policy‐makers identifies foreign capital inflows as one of the primary determinants of banking crises in developed countries. We challenge this view by arguing that external imbalances are destabilizing only when banks face substantial competition from securities markets in the process of financial intermediation. We assemble a dataset of banking crises covering the advanced industrialized countries from 1976 to 2011 and find evidence of a conditional relationship between capital inflows, a well‐developed securities market, and the incidence of banking crises. We further explore the impact of capital inflows on banks’ actual risk taking as indicated by their capital adequacy levels and measures of insolvency risk. Our results demonstrate that prudential capital cushions tend to decline with the combination of capital inflows and prominent securities markets. We highlight the political decisions—often made during the early days of a country's financial development—that determine the relative prominence of banks vs. non‐bank financial institutions and conclude with policy recommendations.     

NONPRICE COMPETITION IN THE TURKISH CREDIT CARD MARKET

Attempts to explain high and sticky credit card rates have given rise to a vast literature on credit card markets. This article endeavors to explain the rates in the Turkish market using measures of nonprice competition. In this market, issuers compete monopolistically by differentiating their credit card products. The fact that consumers perceive credit cards and all other banking services as a bundle allows banks to also employ bank level characteristics to differentiate their credit cards. Thus, the features and service quality of banks are expected to affect credit card rates. Panel data estimations also control for various costs associated with credit card lending. The results show that nonprice competition variables have significant and robust effects on credit card rates. (JEL G21, G28, O16)     

Profit strategy of Greek banks: cross-subsidization and diversification versus complementarity

This study analyses the profit strategy employed by banks in Greece using dynamic panel data techniques and a data set which includes proprietary supervisory data covering the whole Greek commercial banking system from 2004 to 2011. We provide evidence that banks use interest- and non-interest income (non-II) as substitutes rather than complements, with non-II representing an indirect competition instrument by the more efficient banks used in place of direct competition with their peers through prices on loans and deposits. This behaviour is explained by further decomposing the non-II into the relatively stable fees component and the volatile trading income. Moreover, we provide evidence that the net-interest income is primarily affected by the banks’ market power and their operating costs, while more efficient banks exploit their core deposit base to lever their non-II. Finally, macroeconomic developments affect both income components, which are found to be procyclical with respect to economic activity. In particular, the two income components are affected differently from inflation implying that non-II provides a natural hedge against adverse effects from deflation on interest income.     

Pricing beliefs: Empirical evidence from the implied cost of deposit insurance for Islamic banks

Using a large international sample of 348,899 year-firm observations covering 352 Islamic banks and 30,572 conventional banks in 213 countries over the 1999–2013 period, we estimate the deposit insurance premiums of Islamic banks and conventional banks. We find that the premiums for publicly listed Islamic banks are 28% lower than those for publicly listed conventional banks. Moreover, we show that the premiums of privately held banks are significantly higher than those of publicly listed banks. Finally, we show that publicly listed Islamic banks did not record an increase in the level of deposit insurance premiums during the 2007–2009 financial crisis.
