This second edition compares deposit insurance in conventional and Islamic banking systems, focusing on their origins, objectives, and applications. It highlights the critical role of deposit insurance in safeguarding depositors, mitigating risks like moral hazard, maintaining public confidence, and ensuring economic stability. The book examines the evolution of deposit insurance in Western economies, such as the UK, and its adoption in Malaysia, contrasting interest-based conventional systems with Shariah-compliant Islamic models. Key Islamic principles, including Kafalah (guarantee) and Takaful (mutual insurance), showcase the ethical and risk-sharing foundations of Islamic deposit insurance. Emphasizing the need for Shariah compliance, the book explores how Islamic deposit insurance can remain competitive while fostering ethical and sustainable growth. It concludes with recommendations to integrate modern financial strategies with Islamic values, making it a valuable guide for policymakers, financial experts, and academics aiming to enhance global financial practices.
