A panel data analysis of financial inequality was conducted using the PSTR model to determine the threshold level at which excessive financial development worsens inequality. The results reveal evidence of a nonlinear effect between financial development and income inequality where the optimal level of financial development is found to be 19% as a share of GDP above which financial development increases inequality in African countries.  The findings combine into a U-shape relationship, in line with other research in African studies. In this particular case, policy-makers are challenged to come up with policies that enforce the distributive effects of financial development with a view to share wealth equitably.
