Climate Stress Testing
We explore the design of climate stress tests to assess and manage macroprudential risks from climate change in the financial sector. We review the climate stress scenarios currently employed by regulators, highlighting the need to (i) consider many transition risks as dynamic policy choices; (ii) better understand and incorporate feedback loops between climate change and the economy; and (iii) further explore “compound risk” scenarios in which climate risks co-occur with other risks. We discuss how the process of mapping climate stress scenarios into financial firm outcomes can ...

Measuring the Climate Risk Exposure of Insurers
Insurance companies can be exposed to climate-related physical risk through their operations and to transition risk through their $12 trillion of financial asset holdings. We assess the climate risk exposure of property and casualty (P&C) and life insurance companies in the U.S. We construct a novel physical risk factor by forming a portfolio of P&C insurers’ stocks, with each insurer’s weight reflecting their operational exposure to states associated with high physical climate risk. We then estimate the dynamic physical climate beta, representing the stock return sensitivity of each ...

Physical Climate Risk and Insurers
As the frequency and severity of natural disasters increase with climate change, insurance—the main tool for households and businesses to hedge natural disaster risks—becomes increasingly important. Can the insurance sector withstand the stress of climate change? To answer this question, it is necessary to first understand insurers’ exposure to physical climate risk, that is, risks coming from physical manifestations of climate change, such as natural disasters. In this post, based on our recent staff report, we construct a novel factor to measure the aggregate physical climate risk in ...
