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.     

The bank lending channel in the Malaysian Islamic and conventional banking system

This paper examines the bank lending channel of monetary transmission in Malaysia, a country with a dual banking system including both Islamic and conventional banks, over the period 1994: 01-2015:06. A two-regime threshold vector autoregression (TVAR) model is estimated to take into account possible nonlinearities in the relationship between bank lending and monetary policy under different economic conditions. The results indicate that Islamic credit is less responsive than conventional credit to interest rate shocks in both the high and low growth regimes; however, the sub-sample estimation shows that its response has increased in more recent years becoming quite similar to that of conventional credit. Moreover, the relative importance of Islamic credit shocks in driving output growth is notable in the low growth regime, their effects being positive. These findings can be interpreted in terms of the distinctive features of Islamic banks.     

Financial nexus: Efficiency and soundness in banking and capital markets

Based on a modified version of the model used in Corvoisier and Gropp (2002) and De Guevara et al. (2005), we argue that banks' soundness, the structural characteristics and efficiency of the banking sector along with the development of the capital markets constitute a financial nexus. For a data set of 63 developed and developing countries, we find evidences that efficiency significantly modulates the linkages between concentration and soundness. We also find that capital markets' development supports a stable evolution in banking sector. For the relationship between capital markets and soundness, our findings appear to be robust for various measures of the considered variables as well as for different estimation techniques. Regarding the impact of the concentration upon soundness, the results obtained display a certain sensitivity about the way concentration is measured.     

A comparison of conventional versus Islamic banking customers attitudes and judgment

This investigates the impact of customer attitude and judgment regarding conventional and Islamic banking system in Pakistan. This study attempts to find out, how the customers of Islamic banks perceive about Islamic banking practices in terms of Shariah compliance and conventional banking system regarding earning more profits. This study consists on primary data through a well design questionnaire. Four hundred and thirty (430) questionnaires were distributed among different customers of all three types of banking, such as Islamic, conventional and stand-alone branches in order to investigate customer’s attitude and judgment toward banking system. The findings indicate that overall 28% of Islamic banking customers don’t know the essential concept of Islamic financial institution’s in Pakistan. Furthermore, 54% customers of conventional banking show their interest to convert their accounts toward Islamic banks.

     

Volatile capital flows and economic growth: The role of banking supervision

In this paper, we examine the links among banking supervision, the volatility of financial flows, and economic growth. In particular, we explore whether banking regulation mitigates the adverse effects of capital flows volatility on economic growth. Using cross-country data over four decades, we find that banking supervision promotes economic growth by dampening the negative impact of volatile capital flows. The findings hold for both aggregate capital flows and its various components, and for both its net and gross counterparts, while they are also robust for various indicators of regulatory policies. The results support the argument that bank regulatory policy rules designed to ensure financial stability are beneficial to long-run economic growth.     

The liquidity of bank assets and banking stability

This paper shows that an increased liquidity of bank assets, paradoxically, increases banking instability and the externalities associated with banking failures. This is because even though higher asset liquidity directly benefits stability by encouraging banks to reduce the risks on their balance sheets and by facilitating the liquidation of assets in a crisis, it also makes crises less costly for banks. As a result, banks have an incentive to take on an amount of new risk that more than offsets the positive direct impact on stability.     

State contingent banking and asset price bubbles: The case of Islamic banking industry

This paper examines how state contingent banking can help neutralize challenges like debt overhang and lack of optimal risk takings, problems associated with conventional banking that can eventually manifest in the creation of asset price bubbles and a financial crisis. Our analysis also contributes to the literature on Islamic banking which considers state contingent contracts as ideal from a religious perspective. We develop a model of banking with state contingent contracts on the liability and asset sides. Our model shows that in state contingent banking, the returns for the depositors, bank and the borrowers are more aligned with the real economy, which reduces the incentive for excessive borrowing, lending and investing. Our model also shows that with the state contingent banking on the liability side, during periods of heightened macroeconomic risk, depositors' payoff would be more volatile reducing the liquidity influx from the real economy to the banking sector. This neutralizes the pressure on state contingent banks to excessively lend on the asset side. Our model further demonstrates that state contingent contracts on the asset side can help avoid too much (or too little) lending by reducing the managerial discretion in charging low (or high) interest rates. With returns linked to the prices of the underlying assets, state contingent contracts may prevent lack of optimal risk taking.     

Financial liberalization and banking crises: The role of capital inflows and lack of transparency

This paper shows that the liberalization of capital inflows may undermine bank stability in emerging markets. After financial liberalization, uninformed international investors rationally provide large amounts of funds at low cost. This enables insolvent banks to accumulate bad loans. In equilibrium, when a substantial amount of losses may have been accumulated, solvent banks do not find it any longer optimal to issue debt at the interest rate that would compensate investors for risk. Investors anticipate this and stop holding bank debt. When the market for bank liabilities breaks down, insolvent banks default. I show that, because of wasteful investment, the liberalization of capital inflows may decrease aggregate welfare.     

International financial integration through the law of one price: The role of liquidity and capital controls

This paper takes advantage of the fact that some stocks trade both in domestic and international markets to characterize the degree of international financial integration. The paper argues that the cross-market premium (the ratio between the domestic and the international market price of cross-listed stocks) provides a valuable measure of international financial integration and the effectiveness of capital controls. Using autoregressive (AR) models to estimate convergence speeds and non-linear threshold autoregressive (TAR) models to identify non-arbitrage bands, the paper shows that price deviations across markets are rapidly arbitraged away and bands are narrow, particularly so for liquid stocks. The paper also shows that regulations on cross-border capital flows effectively segment domestic markets. As expected, the effects of both types of capital controls are asymmetric but in the opposite direction: controls on outflows induce positive premia, while controls on inflows generate negative premia. Both vary with the intensity of capital controls.     

Market liquidity in the financial crisis: The role of liquidity commonality and flight-to-quality

We examine the dynamics and the drivers of market liquidity during the financial crisis, using a unique volume-weighted spread measure. According to the literature we find that market liquidity is impaired when stock markets decline, implying a positive relation between market and liquidity risk. Moreover, this relationship is the stronger the deeper one digs into the order book. Even more interestingly, this paper sheds further light on so far puzzling features of market liquidity: liquidity commonality and flight-to-quality. We show that liquidity commonality varies over time, increases during market downturns, peaks at major crisis events and becomes weaker the deeper we look into the limit order book. Consistent with recent theoretical models that argue for a spiral effect between the financial sector’s funding liquidity and an asset’s market liquidity, we find that funding liquidity tightness induces an increase in liquidity commonality which then leads to market-wide liquidity dry-ups. Therefore our findings corroborate the view that market liquidity can be a driving force for financial contagion. Finally, we show that there is a positive relationship between credit risk and liquidity risk, i.e., there is a spread between liquidity costs of high and low credit quality stocks, and that in times of increased market uncertainty the impact of credit risk on liquidity risk intensifies. This corroborates the existence of a flight-to-quality or flight-to-liquidity phenomenon also on the stock markets.     

The liquidity impact on firm values: The evidence of Taiwan's banking industry

Liquidity plays an important role in financial markets, especially during a financial crisis. New Basel III regulatory framework highlights the importance of liquidity risk management implemented by financial institutions. Moreover, updated International Financial Reporting Standards (IFRS) require the improvements about fair value measurements and reinforce existing principles for disclosures about the liquidity risk associated with financial instruments. Using the liquidity discount model of Chen (2012), we are able to empirically classify Taiwan's financial institutions into three liquidity categories: safe, crisis contagious and vulnerable. Our findings can serve as an early warning signal for liquidity calamity. In addition, we investigate what factors affect firm-specific liquidity discounts for these institutions and conduct a sub-period analysis, which examines whether there is significant liquidity discounts changes before and after the 2008 financial crisis. We find that liquidity discounts change substantially during the financial crisis. Furthermore, we find that liquidity discounts can be attributed to some firm-specific performance.     

Islamic and conventional portfolios optimization under investor sentiment states: Bayesian vs Markowitz portfolio analysis

This paper investigates the portfolio optimization under investor’s sentiment states of Hidden Markov model and over a different time horizon during the period 2004–2016. To compare the efficient portfolios of the Islamic and the conventional stock indexes, we have employed two approaches: the Bayesian and Markowitz mean-variance. Our findings reveal that the Bayesian efficient frontier of Islamic and conventional stock portfolios is affected by the investor’s sentiment state and the time horizon. Our findings also indicate that the investor’s sentiment regimes change the Islamic and the conventional optimal diversified portfolios.Moreover, the results show that the potential diversification benefits seem to be more important when using the Bayesian approach than when applying the Markowitz approach. This finding is valid for the bearish, depressed, bullish and calm states in Islamic stock markets. However, the diversification of potential portfolios is significant only for the bullish and the bubble states in the conventional financial markets.The findings of the study provided additional evidence for investors to exploit googling investor sentiment states to evaluate the portfolio performance and make an optimal portfolio allocation.     

The early warnings of banking crises: Interaction of broad liquidity and demand deposits

This paper explores the fundamentals in the run-up to systemic banking crises. It applies a visualisation approach that combines elements of an event study analysis and a fan chart technique. The approach helps identify potential leading indicators. A multivariate analysis follows. This paper presents a new early warning system for banking crises built upon these indicators. The interaction of liquidity ratio and loss of demand deposits is incorporated into the model and substantially improves the results. The selected factors are highly statistically significant and robust. The out-of-sample forecasts demonstrate the strong predictive power of the model.

Awareness of Islamic banking products among Muslims: The case of Australia

The purpose of this study is to examine the awareness of Muslim Australians of Islamic banking, particularly profit-and-loss sharing agreements. A sample of 300 Australian Muslims were surveyed utilising a short questionnaire containing specific questions relating to the willingness of respondents to purchase profit-and-loss sharing Islamic banking products. The results indicate that the majority of the respondents are interested in purchasing these products, but are not properly informed about how they function. It was common to find respondents who were keen to purchase Islamic banking products, but only if credit facilities were available. This is contrary to Islamic Shari'ah law, and suggests a lack of understanding of the principles of Islamic finance.     

Optimal liquidity management and bail-out policy in the banking industry

We characterize the profit-maximizing reserves of a commercial bank, and the generated probability of a liquidity crisis, as a function of the penalty imposed by the Central Bank, the probability of depositors' liquidity needs, and the return on outside investment opportunities. We demonstrate that banks do not fully internalize the social cost associated with the bail-out policy if the liquidity needs of individuals are correlated, and that competitive interbank markets will induce banks to raise their reserves under reasonable conditions. The marginal benefits from an interbank market decrease as the correlation between the liquidity shocks of banks increases.

The cost of market power in banking: Social welfare loss vs. cost inefficiency

This paper analyses the relationship between market power in the loan and deposit markets and efficiency in the EU-15 countries over 1993–2002. Results show the existence of a positive relationship between market power and cost X-efficiency, allowing rejection of the so-called quiet life hypothesis [Berger, A.N., Hannan, T.H., 1998. The efficiency cost of market power in the banking industry: A test of the ‘quiet life’ and related hypotheses. Review of Economics and Statistics 8 (3), 454–465]. The social welfare loss attributable to market power in 2002 represented 0.54% of the GDP of the EU-15. Results show that the welfare gains associated with a reduction of market power are greater than the loss of bank cost efficiency, showing the importance of economic policy measures aimed at removing the barriers to outside competition.
