Banking risk measurement and management remain one of many challenges for managers and policymakers. This study contributes to the banking literature and practice in two ways by (a) proposing a risk ranking index based on the Mahalanobis Distance (MD) between a multidimensional point representing a bank's risk measures and the corresponding critical ratios set by the banking authorities and (b) determining the relative importance of a bank's risk ratios in affecting its financial standing using an Adaptive Neuro-Fuzzy Inference System. In this study, ten financial ratios representing five risk areas were considered, namely: Capital Adequacy, Credit, Liquidity, Earning Quality, and Operational risk. Data from 45 Gulf banks for the period 2016-2020 was used to develop the model. Our findings indicate that a bank is in a sound risk position at the 99%, 95%, and 90% confidence level if its Mahalanobis distance exceeds 4.82, 4.28, and 4.0, respectively. The maximum distance computed for the banks in this study was 9.31; only five out of the forty-five banks were below the 4.82 and one below the 4.28 and 4.0 thresholds at 3.96. Sensitivity analysis of the risks indicated that the Net Interest Margin is the most significant factor in explaining variations in a bank's risk position, followed by Capital Adequacy Ratio, Common Equity Tier1, and Tier1 Equity in order. The remaining financial ratios: Non-Performing Loans, Equity Leverage, Cost Income Ratio, Loans to Total Assets, and Loans to Deposits have the least influence in the order given; the Provisional Loans Ratio appears to have no influence.
银行风险度量与管理仍然是管理者和政策制定者面临的众多挑战之一。本研究通过以下两种方式对银行领域的文献和实践做出贡献:(a)基于代表银行风险度量的多维点与银行监管机构设定的相应临界比率之间的马氏距离(MD),提出一个风险排名指数;(b)使用自适应神经模糊模糊系统确定银行风险比率对其财务状况影响的相对重要性模糊推理系统。在本研究中,考虑了代表五个风险领域的十个财务比率,即:资本充足率、信贷、流动性、盈利质量和操作风险。使用了45家海湾银行2016 - 2020年期间的数据来构建模型。我们的研究结果表明,如果一家银行的马氏距离分别超过4.82、4.28和4.0,则在99%、95%和90%的置信水平下处于良好的风险状况。本研究中计算出的银行最大距离为9.31;45家银行中只有5家低于4.82,1家低于4.28,还有1家低于4.0阈值,为3.96。风险敏感性分析表明,净息差是解释银行风险状况变化的最重要因素,其次依次是资本充足率、一级普通股和一级股权。其余财务比率:不良贷款、股权杠杆率、成本收入比、贷款与总资产之比以及贷款与存款之比的影响最小,顺序依次为;临时贷款比率似乎没有影响。
