Assessment of Workplace Gender Diversity and Organisational Performance in Nigerian Banks

The relationship between gender diversity and organisational performance has been extensively debated globally, yet empirical evidence from the Nigerian banking sector remains limited. This study assesses the relationship between gender diversity in management and organisational performance indicators in Nigerian commercial banks. A quantitative research design was employed, with annual performance data from 12 banks over a five-year period (2019-2024) combined with survey responses from 95 senior managers and human resource directors. Data were analysed using panel regression analysis and descriptive statistics. Findings demonstrate a positive and statistically significant relationship between gender diversity at board and senior management levels and return on equity and customer satisfaction scores. Banks with at least 30% female representation in senior management demonstrate measurably stronger innovation culture ratings and lower staff turnover among female employees. However, the study finds that diversity is more often achieved in middle management than at executive levels, suggesting a persistent glass ceiling effect. Tokenism, where one or two women are appointed to satisfy appearance requirements, is identified as a governance concern. Recommendations include CBN regulatory expectations for gender diversity reporting, executive diversity targets, and sponsorship programmes linking senior male leaders to female high-potential employees.
