This paper investigates how banking competition and capital level impact on the risk-taking behavior of banking institutions in the Middle East and North Africa (MENA) region. The topic is perceived to be of significant importance during the COVID-19 pandemic. We use data for more than 225 banks in 18 countries in the MENA region to test whether increased competition causes banks to hold higher capital ratios. Employing panel data techniques, and distinguishing between Islamic and conventional banks, we show that banks tend to hold higher capital ratios when operating in a more competitive environment. We also provide evidence that banks in the MENA region increase their capitalization levels in response to a higher risk and vice versa. Further, banking concentration (measured by the HH-index) and credit risk have a significant and positive impact on capital ratios of IBs, whereas competition does play a restrictive role in determining the level of their capital. The results hold when controlling for ownership structure, regulatory and institutional environment, bank-specific and macroeconomic characteristics. Our findings inform regulatory authorities concerned with improving the financial stability of banking sector in the MENA region to strengthen their policies in order to force banks to better align with capital requirements and risk during the COVID-19 pandemic.
本文考察了银行竞争和资本水平如何影响中东和北非(MENA)地区银行机构的风险承担行为。在 COVID-19 大流行期间,这个话题被认为非常重要。我们使用了 MENA 地区 18 个国家 225 多家银行的数据,以检验竞争加剧是否会导致银行持有更高的资本比率。我们采用面板数据技术,并区分伊斯兰银行和传统银行,结果表明,在竞争更激烈的环境下,银行往往会持有更高的资本比率。我们还提供了证据表明,MENA 地区的银行会根据风险增加而提高资本水平,反之亦然。此外,银行集中程度(以 HH 指数衡量)和信贷风险对伊斯兰银行的资本比率有显著的正向影响,而竞争在决定其资本水平方面则起着限制作用。在控制所有权结构、监管和制度环境、银行特定和宏观经济特征的情况下,这些结果仍然成立。我们的研究结果为监管机构提供了信息,使他们能够加强政策,以提高 MENA 地区银行部门的金融稳定性,迫使银行在 COVID-19 大流行期间更好地使资本要求和风险保持一致。
