In this chapter explores the role of financial systems in modern economies, emphasizing their fundamental mission to circulate funds between economic agents and support inclusive growth. While financial systems are meant to foster economic inclusion and reduce disparities, their reliance on the risk transfer principle—where risk is shifted from depositors to borrowers—can instead amplify inequalities. This model protects fund providers while burdening entrepreneurs and low-asset individuals with the full weight of financial risk, especially during economic downturns. In non-middle-class nations, this leads to financial exclusion, with poorer clusters having limited access to capital or facing exploitative conditions such as high-interest microfinance. The chapter argues that while reforms in financial systems have emerged, their success depends on alignment with effective public policies. Without such synergy, financial systems may deepen socio-economic gaps rather than close them, particularly in nations lacking a strong middle class.
