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.     

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.     

Investor protection and dividend policy: The case of Islamic and conventional banks

This study examines the dividend policy behavior of Islamic and conventional banks operating in Arab markets. These banks operate in an environment of Sharia law and low levels of investor protection. Our results support the substitution agency model of dividends for Islamic banks, and Islamic banks use the dividend policy as a substitute mechanism for alleviating relatively more significant agency problems and higher risks of expropriation by insiders. In these markets, conventional banks operate in a more competitive environment and experience relatively less significant agency problems. In contrast to Islamic banks, conventional banks follow the outcome agency model of dividends.     

Whither Islamic Banking?

Islamic banking is visibly on the rise across the globe, supported by a growing clientele, both Muslim and non‐Muslim, although it has yet to demonstrate that it is a viable alternative to conventional banking. Islamic banking is still under the shadow of conventional banking, not only with products that are strikingly similar to those offered by conventional banks, but also with conventional banks having a strong presence as stakeholders in the Islamic banking industry. Islamic banking is still in the early phase of a presumably long evolutionary process, apparently stuck in the initial phase of product differentiation. Islamic banks are competing with conventional banks rather than among themselves, which does not augur well for innovations and creativity, as it tends to keep them preoccupied with modifications of conventional products with Shari'ah compliance. Islamic banks have arrived at a new crossroads. They could either continue on the same path of what may be termed as ‘head‐on competition’ with conventional banks or change their direction in favour of a ‘niche market’ strategy.

Bank lending,deposits and risk-taking in times of crisis: A panel analysis of Islamic and conventional banks

In this study, we conduct a panel analysis of Islamic and conventional banks to ascertain whether Islamic banks are able to sustain financing supply and whether its growth is higher than conventional bank lending growth in times of stress. For concreteness, we also assess whether the sustained financing supply of Islamic banks is justified by a concomitant increase in Islamic deposit growth and is not linked to excessive risk taking. Utilizing a panel sample of 25 Islamic banks and 114 conventional banks from 10 dual-banking countries, we observe sustained financing supply by Islamic banks but significant reduction in the lending growth by conventional banks during the crisis period. The results further suggest that the financing growth of Islamic banks is higher than the lending growth of conventional banks during the crisis period. However, we find no clear evidence that the deposit growth of Islamic banks behaves differently during the period. Finally, there is no indication to suggest that Islamic banks exhibit excessive risk taking in times of stress. Our results contribute to the evidence supporting the contributive role of the Islamic banking system to financial and economic stability.     

Asymmetrical reaction to US stock-return news: evidence from major stock markets based on a double-threshold model

This paper examines the hypothesis that both stock returns and volatility are asymmetrical functions of past information from the US market. By employing a double-threshold GARCH model to investigate six major index-return series, we find strong evidence supporting the asymmetrical hypothesis of stock returns. Specifically, negative news from the US market will cause a larger decline in a national stock return than an equal magnitude of good news. This holds true for the volatility series. The variance appears to be more volatile when bad news impacts the market than when good news does.     

Price discovery and volatility spillovers in the DJIA index and futures markets

The Dow Jones Industrial Average (DJIA) is the most widely quoted stock index worldwide. This article examines the minute-by-minute price discovery process and volatility spillovers between the DJIA index and the index futures recently launched by the CBOT. The Hasbrouck (1995) cointegrating model suggests that most of the price discovery takes place at the futures market. However, by examining the volatility spillovers between the markets based on a bivariate EGARCH model, a significant bidirectional information flow is found. That is, innovations in one market can predict the future volatility in another market, but the futures market volatility-spillovers to the stock market more than vice versa. Both markets also exhibit asymmetric volatility effects, with bad news having a greater impact on volatility than good news. © 1999 John Wiley & Sons, Inc. Jrl Fut Mark 19: 911–930, 1999     

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.     

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.     

A note on asymmetric stochastic volatility and futures hedging

This note incorporates asymmetric responses to good and bad news within a stochastic volatility framework. It is shown that the asymmetry leads to a greater average optimal hedge ratio. Moreover, the ratio increases with increasing degree of asymmetry. On the other hand, asymmetry has no impact on the hedging performance. The result is consistent with the empirical finding of Brooks, Henry, and Persand (2002) where GARCH models are employed. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:607–612, 2005     

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.     

Underpinning the benefits of green banking: A comparative study between Islamic and conventional banks in Bangladesh

This study aims to compare environmental motives and performance of conventional and Islamic banks in Bangladesh. Green compliance index was developed based on the Bangladesh Bank (the central bank of Bangladesh) guidelines whereas information regarding governance variables is collected from the annual reports of 9 Islamic and 31 conventional banks. Results show Islamic banks are more environmentally friendly compared to their conventional counterparts. Board size is negatively related to green compliance whereas board independence and auditor's type do not have any significant influence on green compliance for both clusters of banks. Compliance with green banking policies enhances the reputation for Islamic banks and accountability and profitability for conventional banks. Results of this study provide useful information for regulatory authorities to formulate policies that are conducive to enhance bank's environmental performance.     

Option volume and volatility response to scheduled economic news releases

In this article, we examine the impact of 21 different types of scheduled macroeconomic news announcements on S&P 100 stock‐index option volume and implied volatility. We find that there is a 2‐h delay after the announcement before volume increases. However, there is an immediate increase in volatility, which slowly dissipates over several hours. Further analysis shows that most of the high volume and volatility after announcements come from the announcements that are considered bad news. That is, bad news creates high volatility and high volume, whereas good news elicits lower volume and is not associated with higher volatility. These results are not consistent with the predictions of any one model. We also find that the announcements that cause the largest reaction in the equity option market are Consumer Credit, Consumer Spending, Factory Inventories, NAPM, and Non‐Farm Payrolls. Six other announcements elicit a mild response. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:315–345, 2003     

Takeover protection and stock price crash risk: Evidence from state antitakeover laws

We exploit the passage of state antitakeover laws to examine the relation between takeover protection and stock price crash risk. We find that firms incorporated in states that passed the laws are negatively associated with future stock price crash risk in the post-law periods, suggesting that takeover protection mitigates bad news hoarding activities. Further analysis shows that the mitigating effect is more pronounced when firms have severe information asymmetry or face strong product market competition. Together, our findings shed new light on the impact of takeover threats on managerial incentives to engage in bad news hoarding.     

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.     

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.     

How potent are news reversals?: Evidence from the futures markets

A theoretical model is presented, which predicts a heightening in return volatility following a news reversal. A reversal occurs when a value of an economic indicator that is larger than the forecasted value is followed in the following month by a value smaller than the forecasted value, or vice versa. The model also suggests that the effects of a news reversal will be more pronounced early in the monthly macroeconomic news cycle. The predictions of the model for trading activity are less clear. The main predictions of the model were tested employing intraday data for the nearby Treasury bond futures contract. Consistent with the model, the data show significantly greater responses in volatility per standard‐deviation surprise when there is a news reversal, than otherwise. Further, the increased sensitivity in volatility is especially perceptible early in the announcement cycle. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 29:42–73, 2009     

Bank board network and financial stability in emerging markets

This study finds that the board network is related to improvements in the financial stability of banks given by asset quality, insolvency risk and volatility of profits. Further, the board network is more critical for the private sector banks in India. The board network also improves the performance of banks, providing evidence in favor of the integrated resource dependence view of the board. Well-connected boards increase information availability and reduce the information asymmetry between the bank and its borrower. For financial firms, restricting the number of directorial positions for bank directors may not have any desirable effect on bank outcomes.     

Volatility spillover and hedging effectiveness among China and emerging Asian Islamic equity indexes

We study the volatility spillover between China and Asian Islamic stock markets. We use a sample of six Islamic MSCI indices from the Asian region, namely China, India, Malaysia, Indonesia, Korea and Thailand obtained from MSCI (Morgan Stanley Capital International). In this paper we analyze the importance of considering spillover effects between emerging Asian Islamic indexes based on the Bivariate VARMA-BEKK-AGARCH model of McAleer et al. (2009), which includes spillover and asymmetric effects. We compute after the effectiveness of portfolio diversification based on the conditional volatility of returns series. Results show a significant positive and negative return spillover from China to selected Asian Islamic stock market and bidirectional volatility spillovers between China, Korea and Thailand Islamic market showing evidence of short-term predictability on Islamic Chinese stock market movements. However there is no short term volatility persistence in India, Indonesia and Malaysia. GARCH results show no persistence in volatility spillover effect in long term from Chinese to Indian, Indonesian and Korean Islamic stock market. Our findings are beneficial for international portfolio diversification for policy makers and investors since the results of portfolio management and hedging effectiveness ratio are different to previous studies.
