The resource curse is an evolving phenomenon in the context of financial development. In this paper, using the firm-level data, we assess the impact of resource curse on the banking sector of those countries with significant dependence on oil production. Our sample spans from 1Q2001 to 4Q2019 and includes commercial banks from twelve oil-producing countries with an oil rent (% of the GDP) being twenty percent and above. We assess the effect of resource curse on banking profit efficiency, asset quality, and solvency using interest rate spreads, credit infections, and the probability of default, respectively, during periods of varying oil prices. Our results show that during episodes of the price boom, the banking efficiency declines, credit infection worsens, and the probability of default would surge. These findings confirm the presence of resources curse and validate the reasons why countries with excess reliance on natural resources tend to have lower financial development. Considering the role of commercial banking in the financial system, these results have important implications for policymakers.

在金融发展的背景下，资源诅咒是一个不断发展的现象。在本文中，我们使用公司层面的数据，评估了资源诅咒对那些严重依赖石油生产的国家的银行业的影响。我们的样本跨度为2001年第一季度至2019年第四季度，其中包括来自十二个产油国的商业银行，其石油租金（占GDP的百分比）为20％或以上。在油价变动期间，我们分别使用利率差，信用感染和违约概率评估资源诅咒对银行利润效率，资产质量和偿付能力的影响。我们的结果表明，在价格暴涨的时期，银行效率下降，信贷感染恶化，违约的可能性会增加。这些发现证实了存在资源诅咒的存在，并证实了过度依赖自然资源的国家金融发展速度较低的原因。考虑到商业银行在金融系统中的作用，这些结果对决策者具有重要意义。
