Islamic Banking Models (Full-Fledged, Subsidiary, and Window): Shariah & Regulatory Implications – Islamic Banking Structural Models: Features and Shariah Parameters  

This paper analyses the structural models of Islamic banking and their Shariah implications. Islamic banking, which accounts for over 70% of global Islamic finance assets, operates through three models: full-fledged Islamic banks, Islamic subsidiaries, and Islamic banking windows. Each model has distinct strengths and weaknesses. Full-fledged banks offer full Shariah autonomy but require high costs. Subsidiaries balance efficiency and compliance through parent-bank support but may face strategic dependence. Windows enable quick market entry with low cost but raise Shariah governance and compliance concerns.

Shariah governance frameworks differ across jurisdictions such as Malaysia and Pakistan, shaping how each model operates and is supervised. Market performance also varies depending on the chosen structure and regulatory environment.

The study concludes that no single model is best; the optimal choice depends on regulatory policy, market maturity, and institutional objectives, balancing growth, efficiency, and Shariah compliance.
