Abstract

The Ghanaian banking sector, grappling with a spectrum of financial risks, presents a compelling case study for understanding the dynamics of risk and profitability in emerging markets. This study seeks to fortify the financial performance of Ghanaian banks through an innovative application of benchmark regression analysis, focusing on critical financial risk and performance metrics. Employing an explanatory research methodology, we harnessed a panel regression model to scrutinize secondary data extracted from the annual income statements of 23 banks, spanning nearly two decades from 2006 to 2023. Our analytical arsenal encompassed the fixed effects model, the Generalized Method of Moments (GMM) within a fixed-effects framework, and Pooled Ordinary Least Squares (POLS) to ensure methodological rigor and robustness. Our findings illuminate the relationship between financial risks and Return on Equity (ROE). Specifically, credit risk was found to exert a significant positive influence on ROE, suggesting that judicious credit extension can be a conduit for profitability. In contrast, liquidity risk was identified as a determinant negatively impacting ROE, underscoring the imperative for effective liquidity management to safeguard banks' long-term solvency. Additionally, market risk was observed to have a positive association with ROE, indicating that strategic exposure to market volatility can potentially enhance financial performance. The implications of this study are manifold, offering actionable insights for policymakers and stakeholders in the banking sector. It advocates for a recalibrated approach to risk management, where banks proactively embrace credit risk while vigilantly addressing liquidity challenges. The study further posits that by forging strategic interconnections, banks can augment their risk management capabilities, thereby bolstering their financial performance and ensuring resilience in the face of market volatility.

摘要

加纳银行业面临一系列金融风险,是理解新兴市场风险与盈利能力动态的一个引人注目的案例研究。本研究旨在通过创新应用基准回归分析来强化加纳银行的财务表现,重点关注关键的金融风险和绩效指标。采用解释性研究方法,我们利用面板回归模型来审查从23家银行的年度损益表中提取的二手数据,时间跨度从2006年到2023年近二十年。我们的分析方法包括固定效应模型、固定效应框架内的广义矩方法(GMM)以及混合普通最小二乘法(POLS),以确保方法的严谨性和稳健性。我们的研究结果揭示了金融风险与股本回报率(ROE)之间的关系。具体而言,发现信用风险对ROE有显著的正向影响,这表明明智的信贷投放可以成为盈利的途径。相比之下,流动性风险被确定为对ROE有负面影响的一个决定因素,凸显了有效流动性管理对保障银行长期偿付能力的紧迫性。此外,观察到市场风险与ROE呈正相关,这表明战略性地承受市场波动可能会提升财务表现。本研究的影响是多方面的,为银行业的政策制定者和利益相关者提供了可操作的见解。它倡导重新调整风险管理方法,银行应积极接受信用风险,同时警惕地应对流动性挑战。该研究进一步认为,通过建立战略联系,银行可以增强其风险管理能力,从而提升其财务表现,并确保在面对市场波动时的弹性。
