This paper uses the data of 405 regional commercial banks and 18 national commercial banks in China from 2007 to 2023 as samples to investigate the impact of climate physical risks on bank liquidity creation. The results show that climate physical risks significantly suppress liquidity creation by regional banks, whereas large state-owned commercial banks increase liquidity creation against the trend to support the real economy. Regional banks will subsequently resume liquidity provision to the real economy, forming a complementary relationship with state-owned banks. This study provides micro-level evidence for coordinating development and security, and underscores the fundamental attribute of finance in serving the people and supporting the real economy.
