Sub-Saharan Africa (SSA) faces many challenges such as poverty, inequality, conflict, corruption and weak institutions. However, it also has the potential for economic growth and development due to its abundant natural resources, young population and increasing global integration. The study examines the impact of financial development on economic growth, unemployment and inflation in sub-Saharan Africa. It also investigates the moderating effects of property rights and legal systems. The study uses panel data from 41 sub-Saharan African countries covering the years 2000–2020 and employs the smoothed sequential quantile regression technique for the empirical analysis. The findings show that at the 25th, 50th and 75th quantiles, financial development has a positive effect on economic growth and unemployment, whilst it has a negative effect on inflation. These results highlight the importance of financial development for promoting economic prosperity and stability in the region. Employment increases whilst inflation and economic progress’ upsides expand when property rights interact with legal systems. Sturdy institutions and law structures are key to tapping financial growth’s full potential for jobs, prices and expansion. The study shows that lawmakers should bolster law frameworks and property rights enforcement, limiting corruption, guarding property rights, improving transparency and backing financial growth. It underscores how vital SSA’s need to grow capital markets, diversify and enable financial inclusion.
