Does the deposit structure affect Islamic bank’s maturity transformation activities? The implications of IFSB liquidity guidelines

Purpose The purpose of this study is to investigate factors influencing the net stable funding ratio (NSFR) in the Islamic banking system. More specifically, the authors analyze the impact of the deposit structure on the liquidity ratio using the two-step generalized method of moments approach during the 2000–2014 period. Design/methodology/approach Based on IFSB-12 and the GN-6, the authors calculated the NSFR for 35 Islamic banks operating in the Middle East and North Africa (MENA) region. Findings The findings of this study show the following: first, ratio of profit-sharing investment accounts have a positive impact on the NSFR, while ratio of non profit-sharing investment accounts increase the maturity transformation risk; second, the results highlight that asset risk, bank capital and the business cycle have a positive impact on the liquidity ratio, while the returns on assets, bank size and market concentration have a negative impact; and third, these results support the IFSB’s efforts in developing guidelines for modifying the NSFR to enhance the liquidity risk management of institutions offering Islamic financial services. Research limitations/implications The most prominent limitation of this research is the availability of data. Practical implications These results will be useful for authorities and policy makers seeking to clarify the implications of adopting the liquidity requirement for banking behavior. Originality/value This study contributes to the knowledge in this area by improving our understanding of liquidity risk management during liquidity stress periods. It analyzes the modified NSFR that was adopted by the IFSB. Besides, this study fills a gap in the literature. Previous studies have used the conventional ratios to determinate the main factors of the maturity transformation risk in a full-fledged Islamic bank based on an early version of NSFR. Finally, most studies focus on the NSFR as proposed by the Basel Committee, whereas the authors investigate the case of the dual-banking system in the emerging economies of seven Arab countries in the MENA region.

Effect of Deposit on the Evaporation Rate of Adhered Salt in Uranium Dendrite

Electrorefining is a key step in pyroprocessing. The solid cathode processing is necessary to separate the salt from the cathode of the electrorefiner since the uranium deposit in a solid cathode contains electrolyte salt. Moreover, it is very important to increase the throughput of the salt separation system due to the high uranium content of the spent nuclear fuel and high salt fraction of uranium dendrites. Therefore, in this study, the effect of deposit on the evaporation of the adhered salt in a uranium deposit was investigated by using the samples of salt in the uranium deposit and salt in the deposit of the surrogate material for the effective separation of the salt. It was found that the salt evaporation rate is dependent on the deposit type and bulk density in the crucible. Additionally, the evaporation rate was found to be lower when the deposit structure is complex; the rate also decreases as the bulk density of the deposit is increased owing to the retardation of the salt vapour transport process. It was concluded that the mass transfer of the salt vapour is an important parameter for the achievement of a high throughput performance in the salt distillation process.

Pengaruh Deposit Structure Dan Ownership Concentration Terhadap Pengungkapan Islamic Corporate Governance Pada Bank Syariah Di Indonesia Dan Malaysia

This research aims to determine the effect of Deposit Structure and Ownership Structure on the disclosure of Islamic Corporate Governance (ICG). Deposit Structure is proxied by the percentage of the Profit Sharing Investment Account (PSIA) to assets, while Ownership Structure used in this research is Blockholder Ownership and Managerial Ownership. The research uses descriptive and verification method with quantitative analysis approach. The results show that simultaneous Profit Sharing Investment Account, Blockholder Ownership, and Managerial Ownership has significant effect on the disclosure of ICG. Partially, Profit Sharing Investment Account indicates significant positive effect on the disclosure of ICG, Blockholder Ownership shows significant positive effect on the disclosure of ICG, while the Managerial Ownership does not affect the disclosure of ICG.

Modeling Deposit Erosion in Internal Turbine Cooling Geometries

Experiments were performed to study the erosion of deposit structures due to large particle impacts (>5 μm). Cone-shaped dust deposits were created in an oversized (6.35 mm diameter) impingement cooling jet at 811 K with 0–5 μm Arizona road dust (ARD). Subsequently, the deposit cones were eroded with larger particle distributions (5–10, 10–20, 20–40, and 40–80 μm ARD) at various velocities and temperatures. It was found that erosion rate increased with increasing particle size and flow velocity and with decreasing temperature. The dependency on size and velocity occurs through the particle's kinetic energy at impact, while the dependency on temperature is related to the adhesive forces in the deposit structure. Using the experimental data, an empirical erosion model was developed to be added to the Ohio State University (OSU) deposition model. A computational flow simulation combined with mesh morphing is shown to capture key features of the erosion physics.
