Boiling banks - how heat harms bank performance
Zusammenfassung
In the face of rising temperatures and increasingly extreme weather events, we examine how heat affects commercial bank performance. We exploit an institutional setting in Germany, which limits the operations of small and medium-sized banks geographically, to identify the regional effect of high temperatures. Our results are based on daily and hourly weather station observations and show that heat reduces the profitability
of regional banks. Further analyses taking into account the composition of the local economy suggest that the decline in performance is caused by the reduced productivity of bank clients. Although not businesses threatening in the last two decades, our results propose that physical climate risks might threaten the business model of local banks in the near future.
