Corruption Undermines African Banks’ Risk Diversification Strategies – KNUST Study
A new study by Kwame Nkrumah University of Science and Technology (KNUST) has found that corruption is significantly weakening efforts by African banks to reduce risk through diversification.
Published in the Research in International Business and Finance, the research analysed 714 banks across 51 African countries and revealed that corruption not only heightens financial risk but also erodes the effectiveness of strategies designed to enhance stability.
According to the study, many banks have expanded beyond traditional lending into fee-based services and other income streams as a way to cushion against risk. However, in high-corruption environments, these diversification strategies fail to deliver the intended protection.
The researchers found that corruption weakens regulatory oversight and reduces transparency, creating room for banks to engage in riskier activities. In such contexts, diversification may actually increase exposure to instability rather than mitigate it.
Drawing on data from 2011 to 2019, the study highlights that the adverse impact of corruption cuts across both large and small banks, underscoring its systemic effect on the continent’s financial sector.

The study concludes that tackling corruption is critical for diversification strategies to succeed. Without stronger regulatory frameworks and institutional controls, efforts to stabilise African banks are unlikely to yield meaningful results.
Researchers are therefore calling for improved transparency and stricter anti-corruption measures, noting that such reforms are essential to strengthening Africa’s banking systems and reducing financial risk.
