Banks versus Hurricanes: A Case Study of Puerto Rico after Hurricanes Irma and Maria
We study Puerto Rico’s experience after the severe hurricane season of 2017 to better understand how extreme weather disasters affect bank stability and their ability to lend. Despite the devastation wrought by two category 5 hurricanes in a single month, we find relatively modest and transitory impacts on bank performance with no evident decline in lending capacity. We discuss various mitigants that help limit bank exposure to extreme weather and whether these mitigants may be vulnerable given the potential for more severe and more impactful climate events.

Maria makes a worst case in some respects because the economy and banks there were vulnerable beforehand, and because Maria struck just two weeks after Hurricane Irma flooded the island. Despite the immense destruction and disruption Maria caused, we find that the island’s economy and banks recovered surprisingly quickly. We discuss the various ...

Investor Attention to Bank Risk During the Spring 2023 Bank Run
We examine how investors’ perception of bank balance sheet risk evolved before and during the March-April 2023 bank run.

We find that the market’s perception of bank risk shifted in both the time series and the cross-section. From January 2022 to February 2023, both factor betas were mostly insignificant, but after the bank run started, they became positive and significant ...
