Flooded credit markets: physical climate risk and small business lending

We document that banks charge higher interest rates on loans granted to European small and medium-sized firms located in areas at high risk of flooding. The risk premium, at 6.4 basis points on average, rises with loan duration, and in the case of smaller borrowers and local specialised banks. By contrast, at-risk firms that rely heavily on intangible and movable assets do not face a higher cost of credit, reflecting lower vulnerability to physical risk. Realised flood risk increases SMEs’ financial vulnerability, as firms in flooded counties are more likely to default on their loans than non-disaster borrowers.
