The Union of Arab Securities Authorities (UASA) issued a study on best practices to promote financial inclusion in Arab capital markets, as part of the implementation of its 2021–2025 Strategic Plan, and within its broader efforts to build inclusive and advanced financial markets aligned with international standards and supportive of sustainable economic growth. The study was prepared by a dedicated working group formed by the Union’s Board during its eighteenth meeting, held in Doha in 2024, in collaboration with the Union’s General Secretariat. It draws on the legislative frameworks and practical experiences of the Union’s member countries, as well as on regional initiatives in the field of financial inclusion. The study includes several chapters that highlight the general framework of key concepts and guiding principles related to financial inclusion. It also outlines tools and indicators that can be used to assess and develop financial inclusion within capital market activities. Additionally, the study addresses ways to improve access to financial markets for underserved segments of society, and the role of financial technology (FinTech) in offering innovative solutions to integrate individuals and small and medium enterprises into the financial system. This study serves as a guiding reference to support Arab regulatory authorities in fostering greater alignment and harmonization of legislation related to financial inclusion, thereby contributing to enhanced cross-border investment flows and deeper integration of Arab financial markets, ultimately advancing a more inclusive, fair, and sustainable investment environment.
