It is, therefore of the utmost importance to mitigate bank failure where possible. Bank supervision plays a key role in ensuring that individual banks, and the banking sector, remain sound. This study analysed seven selected banks in South Africa namely, ABSA, African Bank, Capitec Bank, FirstRand Bank, Nedbank, Standard Bank and VBS Mutual Bank. The CAMELS rating system was applied to evaluate the component and composite ratings for each selected bank. The empirical evidence exhibited that the CAMELS model has been used world-wide and proved valuable in its simplicity and reliability. The results showed that all banks achieved a rating of three or fair, with the exception being African Bank. African Bank, rated four or marginal, continues to struggle to regain market confidence since its cu0ratorship and restructuring. The study further showed that among the selected banks, management quality and liquidity were two components that consistently showed critical weaknesses, which posed concerns for formal supervision. The study utilised One-way ANOVA (Analysis of Variance) to analyse the results of the CAMELS model. It was found that there was no significant difference in the financial soundness of the selected banks as a measure of the CAMELS model. The study further recommended that the banks invest and focus on developing human resource departments to attain and retain high quality managers in terms of qualifications and experience. The banks’ internal policies need to align, not only with the company’s business targets, but also the personal contentment and fulfilment of employees and managers. This will help reduce frictional unemployment in the banking sector. It must be noted that Capitec was the only bank to avoid a marginal or weak rating in the management quality component. To address the poor rating awarded to the liquidity component in all selected banks, it is recommended that senior management, regulators and supervisors need to work together to implement sound liquidity management practices. ii The CAMELS model presents a clear depiction of the financial soundness of a bank and can be comparable to other competitive banks within a country. For this reason, the model would be easily understandable, not only to supervisors and senior management, but also investors, stake-holders, their customers and the general population. It is therefore recommended that the SARB publishes a detailed annual report, which analyses all banks in South Africa by way of the CAMELS model.
