Indonesian economist Adiwarman Karim, Deputy Chairman of the National Sharia Council of the Indonesian Ulema Council (DSN-MUI), has advocated for a "white shadow economy" to enhance economic equality and bolster Islamic finance. He believes expanding the capacity of this informal sector, while formalizing it with transparency, can significantly contribute to economic growth. Karim suggests revisiting the Islamic Banking Law (KUII) to accommodate this approach, stating it can unlock economic potential currently untapped by conventional systems. This strategy aims to integrate previously excluded economic activities into the formal financial landscape, specifically promoting Shariah-compliant financial practices. He emphasizes that increasing economic fairness necessitates innovative solutions beyond traditional financial frameworks. By acknowledging and regulating the existing "shadow economy", Indonesia can unlock substantial economic benefits and fuel the growth of its Islamic finance sector.
