Islamic financial management is a crucial element in sustaining the growth of the Islamic banking industry in Indonesia. This study aims to analyze how Islamic financial management practices are carried out in national banking by referring to the regulations set by OJK, Bank Indonesia, and DSN-MUI. Using a qualitative-descriptive approach, this study examines policy documents, regulatory frameworks, and operational practices of Islamic financial institutions. The results of the study show that the implementation of Islamic financial management has adopted Islamic principles through the structure of fund raising, financing distribution, and risk and compliance governance. However, implementation in the field still faces various obstacles, both from the internal side such as limited human resources and gaps in understanding of regulations, as well as from the external side in the form of accelerated digitalization, weak coordination between authorities, and legal uncertainty. This research emphasizes the need to strengthen the capacity of industry players, adaptive regulatory updates, and institutional synergy so that the Islamic financial system can grow sustainably and in line with sharia principles.
