Using 1,584 listed banks from 64 countries during the COVID-19 pandemic, we conduct the first broad-based international study of the effect of the pandemic on bank systemic risk. We find the pandemic has increased systemic risk across countries. The effect operates through government policy response and bank default risk channels. Additional analysis suggests that the adverse effect on systemic stability is more pronounced for large, highly leveraged, riskier, high loan-to-asset, undercapitalized, and low network centrality banks. However, this effect is moderated by formal bank regulation (e.g., deposit insurance), ownership structure (e.g., foreign and government ownership), and informal institutions (e.g., culture and trust).
我们利用新冠疫情期间64个国家的1584家上市银行,首次开展了关于疫情对银行系统性风险影响的广泛国际研究。我们发现,疫情增加了各国的系统性风险。这种影响通过政府政策应对和银行违约风险渠道发挥作用。进一步分析表明,对于规模大、杠杆率高、风险更高、贷款与资产比率高、资本不足且网络中心度低的银行,对系统性稳定性的不利影响更为明显。然而,这种影响会因正式的银行监管(如存款保险)、所有权结构(如外资和政府所有权)以及非正式制度(如文化和信任)而得到缓和。
