ABSTRACT This study examines the impact of climate policy uncertainty (CPU) on banks' loan loss provisions. Using a sample of 63 listed commercial banks in China from 2007 to 2022, we find that CPU significantly increases banks' loan loss provisions. Banks with higher financial risk and greater climate risk exposure tend to increase their loan loss provisions in response to CPU. This effect is less pronounced for banks with a higher degree of digital transformation, banks with better ESG performance, banks with green commitment, and banks disclosing more substantial climate information. Our findings provide empirical evidence for the importance of reducing CPU by government and regulators from banks' risk management perspective.
