With their unique characteristics, IFIs offer a different approach to finance. This study presents a comprehensive analysis of the international strategies adopted by Islamic Financial Institutions (IFIs) in their pursuit of global expansion. The current global financial landscape presents unique challenges and opportunities for IFIs in their cross-border operations. In this paper, the drivers, obstacles, and outcomes of IFIs' international strategies are evaluated.

Subsequently, the factors that drive IFIs towards international expansion are explored. Increased demand for Sharia-compliant financial services, regulatory reforms, and the advantages of diversification in both product offerings and markets are among important motivators of international expansion for IFIs. How these drivers require IFIs to balance ethical considerations, regulatory compliance and financial performance is highlighted in detail. The challenges and obstacles faced by IFIs in their internationalization phase are analyzed in-depth. Cross-cultural differences, regulatory complexities and the need to achieve Sharia compliance across different contexts come to the fore as important challenges.
