Bank lending channel in a dual banking system: Why are Islamic banks so responsive?

We examine the interest rate sensitivity of both deposits and credits at Islamic and conventional banks in Turkey. We find that the bank lending channel is especially operative for Islamic banks. Impulse responses for conventional and Islamic banks reveal that Islamic bank depositors’ sensitivity to policy rate changes is substantially larger than that of conventional bank depositors. Next to heavily dependence on deposit funding, we consider that inertia in Islamic bank deposit rates impedes these banks to keep those depositors who consider the opportunity cost of monetary policy rates is unbearable. On the lending side, we obtain similar results, implying that tight monetary policy leads to a larger contraction in Islamic bank credits. This finding is a reflection of the favourable attitude of Islamic banks towards small and medium‐sized enterprise (SME) financing. When similar relationships are analysed for currency and inflation shocks, we again find larger responses for Islamic banks showing the cyclical nature of SME credits.     

Capital buffer and credit‐risk adjustments in Islamic and conventional banks

The main purpose of this article is to empirically investigate the interactions between changes in capital buffer and changes in credit risk, using panel data of Islamic and conventional banks located in the Middle East and North Africa (MENA) region over the period 1999–2016. A negative two‐way relationship between the changes in capital buffer and the changes in credit risk is found for the two types of banks, that is, banks tend to decrease their capital buffers in response to an increase in risk exposure and limit their risky activities in response to an increase in their capital buffers. Dividing our period of study into three subperiods to assess the effect of the last financial crisis 2007–08 on the adjustment process, we point out the negative bidirectional relationship between the changes in capital buffer and the changes in credit risk of the two types of banks is present for the three subperiods except the case of conventional banks during the precrisis period. Moreover, we provide evidence that Islamic banks adjust their capital buffer in response to the changes in credit risk regardless of the existence or not of a deposit insurance scheme. In contrast, the negative two‐way relationship between the changes in capital buffer and the changes in credit risk in conventional banks is found only in countries without deposit insurance schemes.     

Efficiency and total factor productivity change of Malaysian commercial banks

This paper analyses the efficiency of Malaysian commercial banks between 1996 and 2002 and finds that while the East Asian financial crisis caused a short-term increase in efficiency in 1998 primarily due to cost-cutting, increases in non-performing loans after the crisis caused a more sustained decline in bank efficiency. It is also found that mergers, fully Islamic banks, and conventional banks operating Islamic banking windows are all associated with lower efficiency. The paper estimates suggest mild decreasing returns to scale, and an average productivity change of 2.37% that is primarily attributable to technical change, which has nonetheless declined over time. Finally, while Islamic banks have been moderately successful in developing new products and technologies, the results suggest that the potential for Islamic banks to overcome their relative inefficiency is limited.     

Public bank lending in Africa in times of crisis

This paper examines State-owned bank lending in Africa in times of crisis. We exploit a sample of 112 banks, including 24 State-owned banks, operating in 8 West African countries over the period 2000–2019. We focus on how bank ownership affects lending, during and after crises. Results indicate that, contrary to domestic-private banks, public banks continue to lend at the same rate during and slightly increase their lending after a crisis. The main explanation of the previous finding is the stability of State-owned bank resources. Finally, the countercyclicality of public banks does not affect their profitability or portfolio quality.     

Islamic financing and bank risks: The case of Malaysia

We examine whether Islamic financing can explain three important bank risks in a country with a dual banking system: credit risk, interest‐rate risk, and liquidity risk. Using Malaysian data, we find that commercial banks with Islamic financing have significantly lower credit and liquidity risks but significantly higher interest‐rate risk than banks without Islamic financing. There is also evidence that bank size is significantly related to credit risk; the proportion of loan sales to total liabilities and bank size are significant determinants of interest‐rate risk; and off‐balance‐sheet financing, the extent of securitization, loan volatility, bank capital, and bank size are statistically significantly related to liquidity risk. © 2005 Wiley Periodicals, Inc.     

Cyclicality of lending in Africa: The influence of bank ownership

Ownership structure of banks has dramatically changed over the past two decades in African countries with privatization and foreign bank entry, including the expansion of Pan-African banks. The objective of this paper is to investigate how bank ownership influences cyclicality of lending in Africa. We are then able to assess how changes in bank ownership influence the economy. To this end, we measure the sensitivity of bank loan growth to GDP per capita growth of the host country with dynamic GMM estimations. We use panel data from 190 commercial banks covering 20 African countries spanning the period from 2002 to 2015. We find that lending of African banks is procyclical for all types of banks. However, we observe that Pan-African banks are the least procyclical banks, while no significant difference in procyclicality is observed between state-owned banks, domestic private banks, and other foreign banks. In addition, we find evidence that foreign banks are influenced by GDP per capita growth of their home country. Therefore, our findings support the view that the expansion of Pan-African banks contributes to reduce cyclicality of lending. However, foreign bank entry can enhance the transmission of external shocks.     

Measuring volatility persistence for conventional and Islamic banks: An FI-EGARCH approach

This paper studies the volatility dynamics of conventional and Islamic banks from the Gulf Cooperation Council (G.C.C) countries during calm and crisis periods, providing a dual comparison in time and space. In particular, it proposes an empirical measure of volatility persistence using the FIEGARCH (Fractionally Integrated Exponential Generalized Auto-Regressive Conditional Heteroscedasticity) model. This specification is useful for reproducing further asymmetry in volatility dynamics and provides a direct measure of long-term volatility dependence. Our findings point to three interesting findings. First, volatility exhibits asymmetry as bad news has a significantly higher impact on volatility than positive news. Second, bad news affects the volatility of conventional banks more strongly than that of Islamic banks. Third, it seems that following a shock, volatility is more persistent in conventional banks than in Islamic Banks. Accordingly, Islamic banks are more resilient than conventional banks, but the degree of resilience is somewhat heterogeneous and sample dependent. Thus, while this may appear to suggest that we could regulate the conventional bank system using the industry rules of Islamic banks, it is worth noting that Islamic banks in Saudi Arabia tend to provide the most resilient Islamic Bank benchmark model.     

The global financial crisis and Islamic finance

The conventional view holds that the current global financial crisis was caused by extraordinarily high liquidity, reckless lending practices, and the rapid pace of financial engineering, which created complex and opaque financial instruments used for risk transfer. There was a breakdown of the lender‐borrower relationship and informational problems caused by a lack of transparency in asset market prices, particularly in the market for structured credit instruments. There was outdated, lax, or absent regulatory‐supervisory oversight; faulty risk management and accounting models; and the emergence of an incentive structure that not only encouraged excessive risk taking but also created a complicit coalition of financial institutions, real estate developers and appraisers, insurance companies, and credit rating agencies whose actions led to a deliberate underpricing of risk. Such a crisis would not have occurred under an Islamic financial system—due to the fact that most, if not all, of the factors that have caused or contributed to the development and spread of the crisis are not allowed under the rules and guidance of Shariah. The current global financial crisis is largely seen as a real test of the resilience of the Islamic financial services industry and its ability to present itself as a more reliable alternative to the conventional financial system. © 2011 Wiley Periodicals, Inc.     

Assessing the Impact of Crude Oil Price and Investor Sentiment on Islamic Indices: Subprime Crisis

This article attempts to shed light on the impact of oil prices, investor sentiment, and conventional index on 11 Islamic indices, particularly during the subprime financial crisis and the oil crisis. Empirical evidence suggests that the Malaysian and Indonesian Islamic indices are very much affected by the oil volatility. Estimation results of the BEKK-GARCH model reveal that the pessimistic sentiment during the subprime crisis is transmitted to Islamic indices, suggesting the herding contagion. The authors' finding indicates that investors can use VIX investor sentiment as an indicator to predict Islamic returns volatility. In addition, the authors find that the oil shock has spilled into Islamic indices. The time-varying correlation indicates strong evidence of the contagion effect of crude oil and investor sentiment measure to Islamic indices during the oil shock and U.S. financial crisis period of 2008–2009.     

Systemic risk,Islamic banks,and the COVID-19 pandemic: An empirical investigation

While operating side-by-side with conventional banks, in a dual-banking system, the systemic risk profile of Islamic banks can be different due to their unique business model. The objective of this study is to understand the evolution of systemic risk in dual-banking systems and determine whether there are any differences in the systemic risk profiles of conventional and Islamic banks during the COVID-19 pandemic. This study also identifies the determinants of systemic importance (measured using spillover indices) of financial institutions. The sample includes ten countries where the Islamic banking sector is considered systemically important and covers the period from November 2015 to November 2020. The empirical results indicate a significant increase in systemic risk, in the sample countries, during the first half which is followed by a recovery in the second half of 2020. Comparative analysis shows that Islamic banks have similar systemic vulnerabilities to systematic and idiosyncratic factors during the exogenously induced real economic shock of the COVID-19. However, Islamic banks pose significantly less spillover to others relative to conventional banks while earning abnormal returns. The results are robust to the inclusion of macroeconomic factors and alternate estimation methodologies. The findings of this study provide valuable insights for the regulators of dual-banking systems.     

The Stock Liquidity of Banks: A Comparison between Islamic and Conventional Banks in Emerging Economies

We explore the stock liquidity of Islamic banks (IBs) and matching conventional banks (CBs) in emerging economies. We find that IBs have higher stock liquidity than CBs, suggesting that investors prefer IBs' stocks and neglect what they consider to be “sin stocks” (i.e., CBs' stocks), which do not conform to their religious beliefs. We also find that the liquidity effects are particularly important for small IBs, and during the global financial crisis. This evidence is stronger in countries with less developed banking sectors and weaker bank supervision and regulation. Hence, faith-driven investors tend to value more norm-conforming stocks (i.e., IBs) during times of distress and uncertainty, and in weaker regulatory environments.     

中国货币政策对银行风险承担行为的影响研究——基于异质性视角

国际金融危机的爆发引发了理论界对货币政策是否影响银行体系稳定更为广泛的关注。文章基于异质性视角构建动态面板数据模型对货币政策与银行风险承担行为之间的关系进行估计,研究结果表明：2003-2011年,货币政策变量对银行风险偏好的影响具有时滞性,贷款利率提高有助于抑制银行风险,货币供应量增加会刺激银行更加冒险;不同银行对货币政策冲击会做出异质反应,随着资本充足率的提高,货币政策对银行风险承担行为的影响效果减弱。因此,加强中国人民银行在宏观审慎监管中的主导作用、建立逆周期的货币政策和资本监管协调机制是后金融危机时代我国监管当局的重要议题。     

Japan's Lost Decade and its Financial System

After briefly explaining the causes of the Japanese asset‐price bubble in the 1980s, this paper analyses why the bursting of the bubble developed into a full‐fledged financial crisis in the late 1990s. In order to cope with this crisis, the Government has injected capital directly into the banking sector and banks have written off enormous amounts of bad loans. However, the Japanese financial sector remains very weak and Japan still faces a number of problems in its financial system. Firstly, the profit margin of banks is too small to cover the increased default risk following the bursting of the bubble, and there are market distortions created by the government‐backed financial institutions and the requirements on new lending to small and medium sized companies. Secondly, banks still have excessive stock investment and crossholding of shares between banks and other companies has weakened the market discipline on entrenched management. Thirdly, the government guarantee of all banking‐sector liabilities should be removed. Once the financial system is stabilised, a risk‐adjusted deposit insurance premium should be introduced so as to strengthen market discipline on banks, and the huge postal saving system should be privatised to create a level‐playing field among deposit taking financial institutions. Besides the foregoing, the weak corporate governance structure of Japanese financial institutions has to be remodelled. The management of banks has shielded themselves by extensive cross‐shareholdings, especially with life insurance companies. There has been extensive mutual provision of capital, most large life insurance companies have weak corporate governance, and many of the large shareholders of banks are life insurance companies. This double gearing between banks and life insurance companies has therefore weakened the market control of Japanese financial institutions.     

Can Islamic banks have their own benchmark?

This paper attempts to answer whether Islamic banks can have their own benchmark rate. In so doing, the paper investigates the nature of the relationship Islamic interbank benchmark rate (IIBR) and its comparable conventional counterpart, London interbank offer rate (LIBOR). The dynamics of the two series are investigated to examine the stability of the spread between IIBR and LIBOR, referred to as ‘Islamic premium’ or ‘piety premium’. The findings suggest that there are both long-term and short-term dynamic relationships between the two rates providing significant evidence of their convergence and co-movement. Our results also show that the existence of the IIBR-LIBOR spread is a reflection of the cost of funding and profit potential of the participating IIBR rate-setters. We find that, in addition to the determinants of the credit spreads, fundamental news of the panel banks are dominant factors driving the ‘piety premium’. We argue that the Islamic banking industry is operating in a global context, where it is highly improbable that its rates can decouple from the global benchmarks. Given that Islamic banking products and their risk return profile are similar to conventional products, arbitrage activities force Islamic rates to converge with the global benchmark rates.     

Systematic Risk in Conventional and Islamic Equity Markets

We aim to compare the systematic risk in conventional and Islamic equity markets by introducing two dynamic risk measures. Accordingly, the level of the systematic risk in conventional markets is slightly higher than the risk in Islamic markets for most of the time. However, this difference is significant in less than 3% of the sample period. More importantly, there is no significant difference in the levels of systematic risk during the global financial crisis of 2008, suggesting that Islamic equities are not able to provide a lower market risk compared with their conventional counterparts in financial turbulent times.     

The influence of bank ownership on credit supply: Evidence from the recent financial crisis

This study examines how bank ownership influenced the credit supply during the recent financial crisis in Russia, where the banking sector consists of a mix of state-controlled banks, foreign-owned banks, and domestic private banks. To estimate credit supply changes, we apply an original approach based on stochastic frontier analysis. We use quarterly data for Russian banks covering the period from the beginning of 2007 to the end of 2009. Our findings suggest that bank ownership affected credit supply during the financial crisis and that the crisis led to an overall decrease in the credit supply. Relative to domestic private banks foreign-owned banks reduced their credit supply more and state-controlled banks less. This supports the hypothesis that foreign banks have a “lack of loyalty” to domestic actors during a crisis, as well as the view that an objective function of state-controlled banks leads them to support the economy during economic downturns.     

Islamic corporate financing: does it promote profit and loss sharing?

Islamic financing instruments can be categorised into profit and loss/risk sharing and non‐participatory instruments. Although profit and loss sharing instruments such as musharakah are widely accepted as the ideal form of Islamic financing, prior studies suggest that alternative instruments such as murabahah are preferred by Islamic banks. Nevertheless, prior studies did not explore factors that influence the use of Islamic financing among non‐financial firms. Our study fills this gap and contributes new knowledge in several ways. First, we find no evidence of widespread use of Islamic financing instruments across non‐financial firms. This is because the instruments are mostly used by less profitable firms with higher leverage (i.e. risky firms). Second, we find that profit and loss sharing instruments are hardly used, whilst the use of murabahah is dominant. Consistent with the prediction of moral‐hazard‐risk avoidance theory, further analysis suggests that users with a lower asset base (to serve as collateral) are associated with murabahah financing. Third, we present a critical discourse on the contentious nature of murabahah as practised. The economic significance and ethical issues associated with murabahah as practised should trigger serious efforts to steer Islamic corporate financing towards risk‐sharing more than the controversial rent‐seeking practice.     

Does financial development reduce income inequality and poverty? Evidence from emerging countries

The objective of this paper is to examine whether bank and stock market development contributes to reducing income inequality and poverty in emerging countries. Using dynamic panel data methods with an updated dataset for the period 1987–2011, we assess the finance–inequality–poverty nexus by taking the separate and simultaneous impacts of banks and stock markets into account. Mixed explanatory findings on panel studies suggest that although financial development promotes economic growth, this does not necessarily benefit those on low-incomes in emerging countries. For the finance–poverty link, we find that neither banks nor stock markets play a significant role in poverty reduction.     

Corporate governance and accounting conservatism in Islamic banks

We examine whether Islamic banks are more likely to be conservative in their financial reporting than conventional banks, as well as how Islamic banks' unique corporate governance system affects accounting conservatism behaviors. Using a large sample of Islamic banks and their matched non‐Islamic banks; based on total assets and geographic location, in 15 countries, we find Islamic banks are more likely to deploy accounting conservatism as measured by loss avoidance, abnormal loan loss provisions, and C‐score, respectively. Islamic banks are about 95% more likely to be more conservative in accounting practices than their counterparts, depending on different model specifications. In addition, we report several board characteristics, such as size, independence, reputation, tenure, and diversity, are important determinants of accounting conservatism in Islamic banks. This relationship indicates certain board traits lead to greater monitoring roles, consequently reducing unethical behavior and increasing the degree of conservatism in accounting practices.     

Does bank efficiency affect the bank lending channel in China?

This work examines the impact of bank efficiency on the bank lending channel in China. Using a sample of 148 Chinese banks over the period 2006–2017, we investigate how the reaction of the loan supply to monetary policy actions depends on a bank's efficiency. We find limited evidence that bank efficiency hampers the effectiveness of monetary policy transmission. In addition, bank efficiency does favor the transmission of monetary policy for banks with low loan-to-deposit ratios. These results suggest that bank efficiency may influence the bank lending channel in certain cases.
