What Do Climate Risk Indices Measure?
As interest in understanding the economic impacts of climate change grows, the climate economics and finance literature has developed a number of indices to quantify climate risks. Various approaches have been employed, utilizing firm-level emissions data, financial market data (from equity and derivatives markets), or textual data. Focusing on the latter approach, we conduct descriptive analyses of six text-based climate risk indices from published or well-cited papers. In this blog post, we highlight the differences and commonalities across these indices.

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 ...

California Wildfires, Property Damage, and Mortgage Repayment
This paper examines wildfires’ impact on mortgage repayment using novel data that combines property-level damages and mortgage performance data. We find that 90-day delinquencies were 4 percentage points higher and prepayments were 16 percentage points higher for properties that were damaged by wildfires compared to properties 1 to 2 miles outside of the wildfire, which suggests higher risks to mortgage markets than found in previous studies. We find no significant changes in delinquency or prepayment for undamaged properties inside a wildfire boundary. Prepayments are not driven by ...

Community Effects of Climate Change in North Carolina
According to a 2021 report by the World Meteorological Organization, hurricanes, floods, heat waves, and droughts have increased in frequency and intensity around the world, accounting for 2 million deaths and $3.64 trillion in losses globally between 1970 and 2019. In the mid-Atlantic region, these events typically result in river and coastal flooding; several recent examples have devastated communities.

Flood Risk Exposures and Mortgage-Backed Security Asset Performance and Risk Sharing
The distribution of risks for residential real estate, including flood risk, depends largely on how these risks are allocated across individual mortgages and within mortgage-backed securities (MBS). This paper is the first to document how flood risks relate not only to individual mortgage performance and underwriting, but also how flood risks correlate to MBS performance and structure. Across residential mortgages we find that defaults are concentrated among the most flood-prone properties and this risk is somewhat offset by larger down payments and slightly higher mortgage rates. Even when ...

Climate-Related Financial Stability Risks for the United States: Methods and Applications
The authors review ten broad classes of models that have been used to study potential financial stability risks arising from climate change in the United States. Their lens is primarily methodological: They describe each modeling technique, its advantages and disadvantages, and its key results. They find that statistical methods, based on reduced-form econometrics, are the most used tool, followed by general equilibrium models. While no approach in isolation addresses the complexity of climate-related financial stability risks, they discuss how existing techniques can be combined to inform ...

Flood Underinsurance
Using data on expected flood damage and National Flood Insurance Program policies, we estimate annual flood risk protection gaps and underinsurance among single-family residences in the contiguous United States. Annually, 70 percent ($17.1 billion) of total flood losses would be uninsured. Underinsurance, defined as protection gaps among properties with positive flood risk and incentives to purchase full flood insurance coverage, totals $15.7 billion annually. Eighty percent of at-risk households are underinsured, and average underinsurance is $7,208 per year. Underinsurance persists both ...

Flood Risk and Firm Location Decisions in the Fed’s Second District
The intensity, duration, and frequency of flooding have increased over the past few decades. According to the Federal Emergency Management Agency (FEMA), 99 percent of U.S. counties have been impacted by a flooding event since 1999. As the frequency of flood events continues to increase, the number of people, buildings, and agriculture exposed to flood risk is only likely to grow. As a previous post points out, measuring the geographical accuracy of such risk is important and may impact bank lending. In this post, we focus on the distribution of flood risk within the Federal Reserve’s ...

Extreme Weather and Financial Market Uncertainty
Extreme weather can have negative, minimal, or even positive effects on business performance—creating significant uncertainty about outcomes for those businesses. Financial markets show heightened uncertainty among investors for companies that have been hit by hurricanes. This uncertainty persists for several months after a hurricane’s landfall, as reflected by continued discussion of hurricanes in analyst calls. Comparing expected volatility to actual volatility shows that markets have underreacted to the uncertainty caused by hurricanes. After Hurricane Sandy, a particularly salient ...
