This study explored the bank-specific and macroeconomic factors influencing capital adequacy in South African commercial banks. In this research, a balanced panel data set comprising 11 recapitalized banks was employed, spanning the period from 2008 to 2019. Employing panel regression techniques including OLS, Fixed Effects, Random Effects, and the Generalized Method of Moments (GMM), the analysis examines the influence of profitability (ROA), bank size, leverage, broad money supply, and the central bank’s monetary policy rate on the Capital Adequacy Ratio (CAR). The results indicate that profitability, bank size, leverage, and the broad money supply are critical determinants of capital sufficiency. Banks with increased profitability and increased exposure to the money supply typically demonstrate more robust capital positions. Larger bank size and increased leverage levels negatively affect capital adequacy ratios. The little impact of the delayed CAR signifies minimal persistence in capital buffer methods over time, implying that banks may not significantly depend on prior year capital conditions in their current capital planning. The study highlights the complex nature of capital sufficiency, influenced by microeconomic factors such as size and leverage, as well as macroeconomic indices like the money supply. The findings substantiate the Capital Buffer Theory and furnish critical insights for regulators, bank executives, and policymakers seeking to bolster the resilience of the banking industry in South Africa.

The COVID-19 pandemic triggered a global economic crisis that significantly impacted the South African banking sector, already weakened by a pre-existing recession. While bank profitability and credit quality declined, stock market reactions appeared less severe, indicating a potential disconnect between fundamentals and investor behaviour. This study explores the influence of investor sentiment on credit risk, lending, and performance (ROA) of selected JSE-listed banks during the pandemic, incorporating behavioural finance perspectives. Panel regression analysis reveals that COVID-19 had a significant negative effect on stock, ROA and ROE, driven by heightened uncertainty and rising non-performing loans. Liquidity and capital positively influenced returns and ROE, reflecting investor confidence in resilient banks. Investor sentiment had a weakly positive impact on returns, but a significant negative effect on both ROA and ROE, suggesting that excessive optimism may have led to riskier lending practices and reduced profitability. Larger banks underperformed in terms of returns, likely due to operational complexity during the crisis. These findings highlight the critical role of behavioural factors in shaping financial outcomes during systemic shocks and provide new insights into emerging market banking dynamics under crisis conditions.

Commercial banks accept deposits and lend money for investment and consumption. This study used five (5) first-tier banks in Nigeria as a case study to analyze the effects of credit risk management on the financial performance of commercial banks. The study examined fifteen (15) years' worth of panel data (from 2005 to 2019), taken from the audited financial reports of five first-tier listed banks. Deposit Money Banks (DMBs) are the only banks used, and they are all listed on the Nigerian Stock Exchange. Non-performing loans (NPL) and expected credit loss impairment provisions (ECL) were utilized in this study as indicators of credit risk management. At the same time, return on assets (ROA) was employed to measure financial performance.

The study examined the dynamic responses of profitability indexes to capital adequacy ratios of authorized internationalized deposit money banks in Nigeria. The data were sourced from the financial year books of the deposit money banks and analyzed with static and dynamic panel estimators. The static estimator shows that the banks have differences in managerial style, size and profitability. Also, it was revealed that return on asset and return on equity responded positively to asset size, efficiency of the use of asset and current ratio in the static models and they were highly significant. However, they were insignificant in the dynamic specifications except asset size that was significant in the return on asset model showing a weak dynamic response of profitability to capital adequacy ratios. Hence the study recommended that Banks should improve their share based as to increase the asset as this will improve profitability.
