Liquidity creation,regulatory capital,and bank profitability

We examine the interrelationships among liquidity creation, regulatory capital, and bank profitability of US banks. We find that regulatory capital and liquidity creation affect each other positively after controlling for bank profitability. However, this relationship is largely driven by small banks and primarily during non-crisis periods. It is also sensitive to the level of banks' regulatory capital and how it is measured. Furthermore, we find that banks which create more liquidity and exhibit higher illiquidity risk have lower profitability. Finally, the relationship between regulatory capital and bank performance is not linear and depends on the level of capitalization. Regulatory capital is negatively related to bank profitability for higher capitalized banks but positively related to profitability for lower capitalized banks. Therefore, a change in regulatory capital has differential impacts on bank performance. Our findings have various implications for policymakers and bank regulators.     

Bank-level stability factors and consumer confidence – A comparative study of Islamic and conventional banks’ product mix

This study examines the behaviour of key bank-level stability factors of liquidity, capital, risk-taking and consumer confidence in Islamic and conventional banks that operate in the same market. Using fixed effect for a sample of 194 banks of Gulf Cooperation Countries between 2000 and 2007, we found that liquidity is not determined by the bank's product mix but rather attributed to systematic factors. However, non-performing assets (representing loans to sub-prime borrowers) have a positive and significant relationship with liquidity, implying that during the crisis Islamic banks tend to take stringent risk strategies compared to conventional banks. Furthermore, Islamic banks generally tend to provide higher consumer confidence levels as they were more capitalized than conventional banks, although conventional banks had carried higher averages of liquidity compared to Islamic banks. Consumer confidence levels or depositors’ discipline as proxied by deposits and customer funding over liabilities generally appear to be higher in Islamic banks than conventional banks.     

Islamic versus conventional banks in the GCC countries: A comparative study using classification techniques

This paper contributes to the empirical literature on Islamic finance by investigating the feature of Islamic and conventional banks in Gulf Cooperation Council (GCC) countries over the period 2003–2010. We use parametric and non-parametric classification models (Linear discriminant analysis, Logistic regression, Tree of classification and Neural network) to examine whether financial ratios can be used to distinguish between Islamic and conventional banks. Univariate results show that Islamic banks are, on average, more profitable, more liquid, better capitalized, and have lower credit risk than conventional banks. We also find that Islamic banks are, on average, less involved in off-balance sheet activities and have more operating leverage than their conventional peers. Results from classification models show that the two types of banks may be differentiated in terms of credit and insolvency risk, operating leverage and off-balance sheet activities, but not in terms of profitability and liquidity. More interestingly, we find that the recent global financial crisis has a negative impact on the profitability for both Islamic and conventional banks, but time shifted. Finally, results show that Logit regression obtained slightly higher classification accuracies than other models.     

Productivity,technology and efficiency of De Novo Islamic banks: Empirical evidence from Malaysia

The impact of foreign banks’ entry on the conventional banking sector has been well documented in the literature. However, empirical evidence on the impact of foreign banks’ entry on the Malaysian Islamic banking sector is completely missing from the literature. By employing the Malmquist Productivity Index method, the article provides, for the first time, empirical evidence on the impact of foreign banks’ entry on the efficiency and productivity of the Islamic banking sector. The empirical findings indicate that the De Novo foreign Islamic banks have been relatively more efficient and productive compared to their domestic and foreign Islamic bank counterparts. The results also suggest that the Malaysian Islamic banking sector has exhibited a higher level of total factor productivity during the post De Novo foreign Islamic banks’ entry period.     

Sukuk market development and Islamic banks’ capital ratios

This paper investigates the impact of Sukuk market development on Islamic banks’ capital ratios using a sample comprising 230 Islamic banks spanning the period 2005–2014. We characterize Islamic bank capital along multiple dimensions, namely: capital adequacy ratio, Tier 1 capital ratio, and capital-to-total assets ratio. We employ both the Prais-Winston technique and the system GMM estimator to tackle potential omitted variable bias, endogeneity, and simultaneity issues. The evidence shows that Sukuk market development has had a negative effect on capital ratios of Islamic banks. We argue that the development of Sukuk markets may have stimulated the competition between Islamic Banks, inducing them to hold lower capital ratios. Our results also show that trade openness and bank liquidity are positively and significantly related to capital ratios, while bank size and loan loss reserve ratio are negatively and significantly related to capital ratios, as expected.     

Funding liquidity and bank risk taking

This study examines the relationship between funding liquidity and bank risk taking. Using quarterly data for U.S. bank holding companies from 1986 to 2014, we find evidence that banks having lower funding liquidity risk as proxied by higher deposit ratios, take more risk. A reduction in banks’ funding liquidity risk increases bank risk as evidenced by higher risk-weighted assets, greater liquidity creation and lower Z-scores. However, our results show that bank size and capital buffers usually limit banks from taking more risk when they have lower funding liquidity risk. Moreover, during the Global Financial Crisis banks with lower funding liquidity risk took less risk. The findings of this study have implications for bank regulators advocating greater liquidity and capital requirements for banks under Basel III.     

Technical efficiency of Islamic and conventional banks with undesirable output: Evidence from a stochastic meta-frontier directional distance function

We examine technical efficiency of Islamic and conventional banks. We contribute to the literature by applying a stochastic meta-frontier directional distance function model with undesirable output, which helps to overcome misestimating technical efficiency. For a sample of banks from 28 countries, we find that a typical Islamic bank is less technically efficient compared to its conventional counterpart. This is due to Islamic banks using less advanced technology compared to conventional banks rather than group-specific technical inefficiency. The findings are robust across six geographical regions of the world.     

Liquidity Coinsurance and Bank Capital

Banks can deal with their liquidity risk by holding liquid assets (self‐insurance), by participating in interbank markets (coinsurance), or by using flexible financing instruments, such as bank capital (risk sharing). We use a simple model to show that undiversifiable liquidity risk, that is, the liquidity risk that banks are unable to coinsure on interbank markets, represents an important risk factor affecting their capital structures. Banks facing higher undiversifiable liquidity risk hold more capital. We posit that, empirically, banks that are more exposed to undiversifiable liquidity risk are less active on interbank markets. Therefore, we test for the existence of a negative relationship between bank capital and interbank market activity and find support in a large sample of U.S. commercial banks.     

The regulations–risk taking nexus under competitive pressure: What about the Islamic banking system?

Does market power condition the effect of bank regulations and supervision on bank risk taking? We focus on three regulatory tools: capital requirements, the restriction of activities, and official supervisory powers. Employing 10 years of unbalanced panel data on 123 Islamic and conventional banks operating in the Middle East and Asia, we arrive at the following conclusions. First, banking market power strengthens the negative impact of capital regulation on bank risk taking. Second, our empirical results suggest that the negative effect of activity restrictions on stability is diminished when banks have greater market power. Finally, we do not find strong evidence that the negative effect of supervisory power on banks’ risk taking is conditioned by their competitive behavior. In further analysis, we differentiate between Islamic and conventional banks regarding their competition, as well as their risk behavior. The results differ according to the banking business model. These findings could be useful for bank regulators in light of the accomplishment of Islamic banks’ regulatory framework. Indeed, the adoption of Basel III represents a significant regulatory challenge, given that it does not take into account the specificities of Islamic banks.     

The effect of bank capital on lending: Does liquidity matter?

This paper uses a sample of quarterly observations of insured US commercial banks to examine whether the effect of bank capital on lending differs depending upon the level of bank liquidity. We find that the effect of an increase in bank capital on credit growth, defined as growth rate of net loans and unused commitments, is positively associated with the level of bank liquidity only for large banks and that this positive relationship has been more substantial during the recent financial crisis period. This result suggests that bank capital exerts a significantly positive effect on lending only after large banks retain sufficient liquid assets.     

Bank regulatory capital and liquidity: Evidence from US and European publicly traded banks

The theory of financial intermediation highlights various channels through which capital and liquidity are interrelated. Using a simultaneous equations framework, we investigate the relationship between bank regulatory capital and bank liquidity measured from on-balance sheet positions for European and US publicly traded commercial banks. Previous research studying the determinants of bank capital buffer has neglected the role of liquidity. On the whole, we find that banks decrease their regulatory capital ratios when they face higher illiquidity as defined in the Basel III accords or when they create more liquidity as measured by Berger and Bouwman (2009). However, considering other measures of illiquidity that focus more closely on core deposits in the United States, our results show that small banks strengthen their solvency standards when they are exposed to higher illiquidity. Our empirical investigation supports the need to implement minimum liquidity ratios concomitant to capital ratios, as stressed by the Basel Committee; however, our findings also shed light on the need to further clarify how to define and measure illiquidity and also on how to regulate large banking institutions, which behave differently than smaller ones.     

COVID-19 as a stress test: Assessing the bank regulatory framework

The broad economic damage of the COVID-19 pandemic poses the first major test of the bank regulatory reforms put in place after the Global Financial Crisis. Our study assesses the U.S. regulatory framework, with an emphasis on capital and liquidity requirements. Prior to the COVID-19 crisis, banks were well capitalized and held ample liquid assets, which partly reflects enhanced requirements. The overall robust capital and liquidity levels resulted in a resilient banking system, which maintained lending and market making through the early stages of the pandemic. Trading activity was a source of strength for banks, reflecting in part a prudent regulatory approach. That said, leverage requirements are associated with more repo position netting by banks, with potential implications for market making.     

Dividend payout strategies and bank survival likelihood: A cross-country analysis

In this cross-country study, we examine whether dividend payout decisions affect the survival likelihood of banks. Using unique international banking data from 11 countries from 2010 to 2019, we find that higher levels of cash dividend payouts increase a bank's survival likelihood, as paying dividends lowers agency problems and cost of debt and facilitates greater public monitoring. Our extended analysis shows an inverted U-shaped relation between large dividends and survival likelihood. At higher levels, payout is related to a safer position of banks in terms of default; however, at very high levels of dividends, when the levels of payouts exceed a threshold, such payout lowers the likelihood of survival. We additionally investigate the effect of the bank type to assess whether differential effects could be realised under the constrained dividend model of Islamic banks compared to the conventional banking model. Our results, interestingly, show that the positive effect of dividend payouts on bank survival is more pronounced in conventional than Islamic banks. This finding is explained by the dominant liquidity management challenges pertaining to the Islamic banking business model in which banks retain more cash and pay lower dividends. Our findings offer important insights and policy implications for regulators, bankers and a broad set of stakeholders engaging with both banking sectors.     

The impacts of risk-taking behaviour and competition on technical efficiency: Evidence from the Chinese banking industry

This paper tests the impact of risk and competition on efficiency in the Chinese banking industry over the period 2003–2013. Comprehensive types of risk-taking behaviour are considered including credit risk, liquidity risk, capital risk, and insolvency risk. Competition is measured by the Lerner index. The results are cross-checked using an alternative econometric technique as well as an alternative competition indicator. The findings show that the technical and pure technical efficiencies of Chinese commercial banks are significantly and negatively affected by liquidity risk. They further show that greater competition precedes declines in technical and pure technical efficiencies of Chinese commercial banks. The results suggest that Chinese bank efficiency is significantly affected by bank diversification, banking sector development, stock market development, inflation and GDP growth rate. The findings also indicate that, compared to state-owned commercial banks, joint-stock commercial banks and city commercial banks have lower technical and pure technical efficiencies.     

Does better capitalization enhance bank efficiency and limit risk taking? Evidence from ASEAN commercial banks

This paper assesses the dynamic causal relationships among bank risk, capital, and efficiency. Using a panel dataset of commercial banks in five ASEAN countries from 2005 to 2015, we employ panel vector autoregression analysis to take into account the endogeneity and interdependencies of these three variables while holding other shocks constant. We find that in general, better capitalized banks in ASEAN countries are more efficient and take less credit risk. However, high-efficiency banks tend to maintain low levels of capital, whereas low-efficiency banks have higher capital ratios. We also analyze the sensitivity of the relationships among capital, risk, and efficiency to ownership structure, bank size, and the periods before and after the 2008 crisis.     

Islamic vs. conventional banking: Business model,efficiency and stability

How different are Islamic banks from conventional banks? Does the recent crisis justify a closer look at the Sharia-compliant business model for banking? When comparing conventional and Islamic banks, controlling for time-variant country-fixed effects, we find few significant differences in business orientation. There is evidence however, that Islamic banks are less cost-effective, but have a higher intermediation ratio, higher asset quality and are better capitalized. We also find large cross-country variation in the differences between conventional and Islamic banks as well as across Islamic banks of different sizes. Furthermore, we find that Islamic banks are better capitalized, have higher asset quality and are less likely to disintermediate during crises. The better stock performance of listed Islamic banks during the recent crisis is also due to their higher capitalization and better asset quality.     

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.     

Does the ownership structure matter for banks’ capital regulation and risk-taking behavior? Empirical evidence from a developing country

This paper applies the two-stage least squares (2SLS) estimator to examine the bi-directional relationship between banks’ capital regulation and risk-taking behavior concerning the impact of ownership structure. We have used a balanced panel dataset of banks from a developing country over the most recent period between 2006 and 2014. The empirical findings of this study suggest that higher capital regulation enhances banks’ stability when it combats with credit risk but higher credit risk often persuades abating capital ratio. Particularly, the key results are as follows: (i) the higher association of minority active shareholding in stability issues is positive; (ii) the higher contribution of active share holding promotes banks’ capital ratio; (iii) the lower ownership concentration prevents credit risk; (iv) private commercial banks are more risk averse and stable than state-owned banks and other type of banks; and (v) notably, Islamic banks show their superiority through overall performance despite their lower capital stability than conventional banks. Besides, no models show significant non-linear relationship between capital regulation and risk-taking except models of stability show a U-shaped relation in capital equation, indicating that when regulatory pressure works in a country then bank lose solvency at the initial stage. Finally, it also provides some imperative policy implications which will be very useful for a wide range of stakeholders.     

Examining the Relationships between Capital,Risk and Efficiency in European Banking

This paper analyses the relationship between capital, risk and efficiency for a large sample of European banks between 1992 and 2000. In contrast to the established US evidence we do not find a positive relationship between inefficiency and bank risk‐taking. Inefficient European banks appear to hold more capital and take on less risk. Empirical evidence is found showing the positive relationship between risk on the level of capital (and liquidity), possibly indicating regulators' preference for capital as a mean of restricting risk‐taking activities. We also find evidence that the financial strength of the corporate sector has a positive influence in reducing bank risk‐taking and capital levels. There are no major differences in the relationships between capital, risk and efficiency for commercial and savings banks although there are for co‐operative banks. In the case of co‐operative banks we do find that capital levels are inversely related to risks and we find that inefficient banks hold lower levels of capital. Some of these relationships also vary depending on whether banks are among the most or least efficient operators.     

Monetary transmission during low interest rate environment in a dual banking system: evidence from Malaysia

This study aims to determine the role of bank loans in the transmission of monetary policy in an environment of low interest rate in the context of a dual banking system in Malaysia. By adopting a balanced panel data approach applied on data covering the period from 2000 to 2011, the study finds that changes in the monetary policy have no significant impact on the level of financing extended by the Islamic and conventional banks. However, bank-specific factors, namely size and liquidity play an important role in influencing the lending behaviour of both the Islamic and conventional banks, whereas capitalization is relevant only for the Islamic banks. Findings of the study provide important input for effective monetary policy implementation in countries with increasing presence of the Islamic banks.
