Abstract

The COVID-19 pandemic is damaging economies across the world, including financial markets and institutions in all possible dimensions. For banks in particular, the pandemic generates multifaceted crises, mostly through increases in default rates. This is likely to be worse in developing economies with poor financial market architecture. This paper utilizes Bangladesh as a case study of an emerging economy and examines the possible impacts of the pandemic on the country's banking sector. Bangladesh's banking sector already has a high level of non-performing loans (NPLs) and the pandemic is likely to worsen the situation. Using a state-designed stress testing model, the paper estimates the impacts of the COVID-19 pandemic on three particular dimensions-firm value, capital adequacy, and interest income-under different NPL shock scenarios. Findings suggest that all banks are likely to see a fall in risk-weighted asset values, capital adequacy ratios, and interest income at the individual bank and sectoral levels. However, estimates show that larger banks are relatively more vulnerable. The decline in all three dimensions will increase disproportionately if NPL shocks become larger. Findings further show that a 10% NPL shock could force capital adequacy of all banks to go below the minimum BASEL-III requirement, while a shock of 13% or more could turn it to zero or negative at the sectoral level. Findings call for immediate and innovative policy measures to prevent a large-scale and contagious banking crisis in Bangladesh. The paper offers lessons for other developing and emerging economies similar to Bangladesh.

摘要

新冠疫情正在损害全球经济,包括金融市场和机构的各个方面。尤其是对银行而言,疫情引发了多方面的危机,主要是通过违约率的上升。在金融市场架构不完善的发展中经济体,情况可能更糟。本文以孟加拉国作为新兴经济体的案例研究,考察疫情对该国银行业可能产生的影响。孟加拉国银行业已经存在高水平的不良贷款,疫情可能会使情况恶化。本文使用国家设计的压力测试模型,估计了在不同不良贷款冲击情景下,新冠疫情对企业价值、资本充足率和利息收入这三个特定方面的影响。研究结果表明,在单个银行和行业层面,所有银行的风险加权资产价值、资本充足率和利息收入都可能下降。然而,估计显示大型银行相对更脆弱。如果不良贷款冲击变大,这三个方面的下降将不成比例地增加。研究结果进一步表明,10%的不良贷款冲击可能会迫使所有银行的资本充足率低于巴塞尔协议III的最低要求,而13%或更高的冲击可能会使行业层面的资本充足率变为零或负数。研究结果呼吁立即采取创新政策措施,以防止孟加拉国发生大规模传染性银行业危机。本文为其他与孟加拉国类似的发展中经济体和新兴经济体提供了经验教训。
