Economic and financial debates no. 45: The effects of climate change-related risks on banks: a literature review
This literature review describes the recent empirical literature in economics and finance focusing on how climate change-related risks affect banks, with a particular emphasis on microeconomic evidence. The comparison of empirical estimates shows that banks and bond markets perception of climate change-related risks, assessed through the lens of variations on banks’ loan and bond spreads, as well as loan supply, is limited. Indeed, for both loan and bond spreads, most estimates obtained from banks and bond markets of the effect of climate change are below 50 bp. In comparison, studies on stock markets document responses that are more substantial. In real estate markets, there is evidence of price effects notably for flood risks associated with sea level rise. However, some studies indicate that climate risks could be underestimated. We note challenges related to the measurement of adaptation potential, non-linear changes in hazards and responses, and the aggregation of effects across studies, markets, and bank portfolios.
