Report: Climate Change and Sovereign Risk

This joint report provides a comprehensive analysis of the ways in which climate risks affect sovereign risk, demonstrating new empirical evidence of how climate risk and resilience influence the costs of capital. It also explores the implications for Southeast Asia in particular, where countries are highly exposed to climate change risks and their economic consequences. Lastly, the report outlines five policy recommendations based on these findings. The report was a collaboration between the Centre for Sustainable Finance at SOAS University of London, the Asian Development Bank Institute, the World Wide Fund for Nature Singapore and Four Twenty Seven.

“Climate Change and Sovereign Risk” outlines six transmission channels through which climate change affects sovereign risk and in turn the cost of capital, providing examples of each and explaining how they’re connected. It uses empirical analysis to demonstrate the significant impacts of climate risk exposure on the cost of capital. Using a sample of 40 developed and emerging economies, econometric analysis shows that higher climate risk vulnerability leads to significant rises in the cost of sovereign borrowing. Premia on sovereign bond yields amount to around 275 basis points for economies highly exposed to climate risk. This risk premium is estimated at 113 basis points for emerging market economies overall, and 155 basis points for Southeast Asian economies.

To further explore these channels, the report provides a closer look at Southeast Asia, a region with significant exposure to climate hazards such as storms, floods, sea level rise, heat waves and water stress. Physical risks are expected to considerably affect economic activity, international commerce, employment and public finances across Southeast Asian countries. Transition risks will be prominent as exports and economies become affected by international climate policies, technological change and shifting consumption patterns. The implications of climate change for macrofinancial stability and sovereign risk are likely to be material for most if not all countries in Southeast Asia.

The report highlights the need for governments to climate-proof their economies and public finances or potentially face an ever-worsening spiral of climate vulnerability and unsustainable debt burdens. It outlines five policy recommendations, emphasizing the importance for financial authorities to integrate climate risk into their risk management processes and for governments to prioritize comprehensive climate vulnerability assessments and work with the financial sector to promote investment in climate adaptation.

The report was originally posted by SOAS University of London.

Report: Measuring TCFD Disclosures

September 24, 2020 – Vigeo Eiris and Four Twenty Seven Report. The TCFD recommendations helped to catalyze a global conversation on the need for increased climate risk assessment and disclosure. While there is much progress still to be made, there has recently been significant developments in the uptake and quality of TCFD-aligned climate risk disclosures. This report explains Vigeo Eiris’ new TCFD Climate Strategy Assessment dataset, sharing key findings of how firms’ disclosure align with each element of the TCFD framework and includes a case study on how companies’ risk reporting compare to their physical risk exposure.

Consistent climate risk disclosure is essential to improving market transparency and building a more resilient financial system. As devastating extreme events, regulatory developments and investor pressure have led to an increase in climate risk disclosure, the Task Force on Climate-related Financial Disclosures’ (TCFD) recommendations have become a global reference. Moody’s affiliate Vigeo Eiris’ new TCFD Climate Strategy Assessment dataset provides a granular view of how 2,855 companies report in line with TCFD recommendations.

This new Vigeo Eiris and Four Twenty Seven report, Measuring TCFD Disclosures, explores the key findings from this assessment, highlighting companies’ disclosures in governance, strategy and risk management.  We find that while 30% of companies have identified at least one climate-related risk that may affect their business, only 3% have disclosed enhanced due diligence for projects and transactions. The report highlights examples from the three sectors of energy, electric & gas utilities and diversified banks to compare reporting for several indicators within each TCFD category. It  includes a case study on the energy sector to review how companies’ physical risk exposure compares to their risk disclosure. Based on Four Twenty Seven’s data on physical climate risk, we find that there is still significant discrepancy between how companies are exposed to climate risk and what they disclose. This is essential for investors to understand when leveraging disclosures to assess their own risk exposure and when engaging with companies around improving climate risk assessment and disclosure.

Key Findings:

  • Overall:
    • 30% of the companies have identified at least one climate-related risk that may affect their business and strategy over the short, medium and long term.
    • Physical risks are most frequently reported, followed by policy and legal risks.
  • Governance:
    • 15% of the companies report on having assigned climate-related responsibilities to management.
    • 16% have established processes to inform board members about climate change issues.
  • Strategy
    • 12% of all assessed companies report the development of products or services that contribute to the low-carbon economy, making it the most common Strategy disclosure.
    •  Only 8% of the European and 7% of the North American companies in the panel disclosed climate change as a material factor in their financial planning.
  •  Risk Management:
    •  30% of the assessed energy companies report using an internal carbon price.
    •  Enhanced due diligence for projects and transactions remains a minority practice, with only 3% of companies disclosing information on this specific recommendation.

Newsletter: Wildfires, Storms and Their Impacts on Credit Risk

Four Twenty Seven's monthly newsletter highlights recent developments in climate risk and resilience. This month we discuss the costs of climate hazards, share updates on Moody's ESG and highlight recent developments in climate risk regulation.

In Focus: The Current Reality of the
Climate Crisis

Devastating Human & Economic Costs of Wildfires

As cities on the West Coast take turns with the worst air quality in the world, and cope with evacuations and loss of life and property from record-breaking wildfires, there is increasing evidence about the longer-term implications of these devastating events. After several years of catastrophic fires in California, exacerbated by hot and dry conditions driven by climate change, homes in exposed areas are likely to decline in value, which in turn can increase mortgage default rate, with severe market implications.

Likewise, as the COVID-19 pandemic limits firefighting resources and makes evacuations particularly challenging, new research continues to emerge about the devastating health impacts of wildfire smoke. For example, "Researchers from the University of Tasmania identified 417 extra deaths that occurred during 19 weeks of smoky air, and reported 3,100 more hospital admissions for respiratory and cardiac ailments and 1,300 extra emergency room visits for asthma" during Australia's bushfires last year.

This is not just a current concern in the U.S., but rather wildfire potential is increasing  globally, and regions such as Brazil and Portugal are also enduring fires. Four Twenty Seven's recent analysis on global wildfire potential assesses how conditions will become more conducive to wildfires in regions around the world.

Dire Records Foreshadow Worsening Extremes

As wildfires ravage the west, Hurricane Sally began to hit southeastern Mississippi and the western Florida Panhandle on Tuesday. The slow-moving storm is expected to continue to drop rain and lead to heavy wind as it moves to shore on Wednesday. This is the 18th named storm of the Atlantic hurricane season and the earliest S-named storm on record. Several more hurricanes have already formed in the Atlantic and these back-to-back storms present significant challenges; diminishing the window for search and rescue, increasing the duration of flooding and power outages and exacerbating COVID-19 challenges. Sea level rise driven by climate change worsens storm surge risk during hurricanes and warmer oceans can fuel stronger storms.

This comes as this year's first seven months were the second hottest on record and in the Northern Hemisphere July was the hottest on record, beating the previous record set just last year. This is increasingly evident in the Arctic, where satellite imagery shows that the region's largest remaining ice shelf lost a 110 square km portion and where Bering Sea ice was at a record low during 2018 and 2019. This affects ecosystems and Indigenous communities and contributes to feedback loops of warming in the region when reflective ice is replaced by dark water. Meanwhile, in Antarctica two glaciers that are already contributing to around 5% of global sea level rise were recently found to be less stable than previously understood.

Global Ports Exposed to Floods, Sea Level Rise

Sea ports handle 80% of global goods, so disruptions have significant wide-reaching consequences. This recent Economist article leverages Four Twenty Seven's data to explore risk exposure of about 340 of the world's largest ports. The analysis found that 55% of global trade goes through ports that are highly exposed to at least one hazard, such as floods, sea level rise, storms and wildfires and that 8% of trade passes through ports highly exposed to at least three hazards. This points to a need for risk assessment and resilience investment at ports, which requires capacity-building for port managers and an increase in adaptation finance.

U.S. CFTC Releases Report on Climate Risk

Last week the U.S. Commodity Futures Trading Commission released a report highlighting the economic risks of climate change and emphasizing the need for the financial system to address these risks. The first such report to be issued by a U.S. government entity, it covers both physical and transition climate risks and calls for a nationwide price on carbon. However, this comes two weeks after the U.S. Securities and Exchange Commission released updated disclosure requirements that don't include climate change.

UK Releases Consultation on Mandating TCFD Disclosure

The UK's Department for Work and Pensions released a public consultation on a proposal to mandate climate risk disclosure. The policy would require pension funds of at least £5 billion to assess and disclosure their climate risks and opportunities under several scenarios by October 2021 and would also apply to funds of at least £1 billion in 2022. Respond by October 7th.
Meanwhile, yesterday, New Zealand announced that it would mandate TCFD disclosure on a comply or explain basis by 2023.

Moody’s: U.S. Nuclear Operators Exposed to Physical Climate Risks

Increasing physical climate hazards affect the operations and costs of nuclear plants due to their water needs and reliance on critical equipment. In its report, Nuclear Operators Face Growing Climate Risk but Resiliency Investments Mitigate Impact, Moody’s Investors Service leverages Four Twenty Seven’s physical climate risk data to explore the exposure of nuclear power plants to climate hazards, including heat stress, water stress, flooding and hurricanes.

The analysis found that nuclear power plants are vulnerable to increasing frequency of extreme weather conditions such as flooding and storm surge, due to their need for water cooling which means many plants are adjacent to large bodies of water. Technology and equipment required for safe plant operation are susceptible to damage and nuclear plants along the East Coast and the Gulf of Mexico are particularly exposed to floods from sea level rise.

Clustered in the Midwest and eastern part of the U.S., market-based plants face less risk of hurricanes or sea level rise than regulated/cost-based plants. However, they face increased heat stress and water stress which can reduce plants’ cooling capacity. The credit impact for market-based plants can be more significant than the regulated plants that are more easily able to make-up costs through rate recovery programs.

Nuclear plant operators face physical and economic risks due to extreme events driven by climate change, and operators and owners will have to consider these risks and explore increased resilience options, as they approach license expiration and renewal processes between 2030 and 2050.

Moody’s Including Four Twenty Seven Climate Risk Data in Research and Ratings

Four Twenty Seven’s physical climate risk data now informs Moody’s ratings and research on US commercial mortgage-backed securities and commercial real estate collateralized loan obligations. Moody’s presale reports include a physical climate risk table for the property backing the loan, showing its exposure to floods, heat stress, hurricanes & typhoons, sea level rise, water stress and wildfires in the next 10 to 20 years. Read the press release from Moody’s Investors Service:

——————————

New York, August 11, 2020 —

  • Four Twenty Seven measures the degree of risk from floods, heat stress, hurricanes and typhoons, sea level rise, water stress, and wildfires
  • Moody’s presale reports now include physical climate risk tables for the properties backing the loans in CMBS and CRE CLO transactions

Moody’s Investors Service is now including climate risk data and analytics from majority-owned affiliate Four Twenty Seven in its research on and ratings process for US commercial mortgage-backed securities (CMBS) and commercial real estate collateralized loan obligations (CRE CLOs). While Four Twenty Seven climate risk scores inform Moody’s ratings, they are not a direct input into Moody’s rating models.

“CRE market participants are particularly exposed to physical risks associated with climate change, which could impact both properties and the surrounding communities,” said Nicholas Levidy, a managing director with Moody’s Structured Finance Group. “In the coming decades, climate hazards could disrupt access to certain locations and operations, damaging infrastructure and, where climate events become chronic, undermining an asset’s viability. The Four Twenty Seven scoring system provides a systematic way for us to monitor the impacts of gradually worsening extreme weather hazards.”

As extreme weather events and conditions become more frequent and severe, anticipation of these hazards will be increasingly reflected in insurance costs, and eventually also capital expenditures and commercial property valuations, Levidy says. Climate change could also raise utility costs due to factors such as higher demand for energy or a lack of water.

“Four Twenty Seven leverages global climate models to help investors and lenders understand what future risks related to climate change are likely to emerge,” said Emilie Mazzacurati, founder and CEO of Four Twenty Seven. “Our analytics look 10 to 20 years into the future, with this data compared to historical conditions to produce a measure of expected disruption from climate change.”

Four Twenty Seven provides aggregated climate risk scores and portfolio analytics that quantify a property’s exposure to the impacts of each of the six physical climate risks, with scores ranging from ‘no risk’ to ‘red flag,’ or extremely high risk. Four Twenty Seven scores are “gross” exposure scores, which Moody’s considers and supplements in the context of any property- or borrower-specific risk mitigants that may exist such as insurance, building systems, age of buildings, infrastructure improvements or government intervention measures.

Moody’s presale reports now include a physical climate risk table for the property backing each loan in a CMBS or CRE CLO transaction. The table provides the risk level and a site score for the given property, as well as a country benchmark score, for each of the six climate hazards.

The combination of data and analytics will enable commercial real estate professionals to better understand the exposure of their properties to the physical impacts of climate change, and to factor that insight into their investment decision-making processes.

Climate Change and Wildfires: Projecting Future Wildfire Potential

August 6, 2020 – Four Twenty Seven Report. Wildfires are complex physical phenomena that come at extraordinary costs to human and natural systems. Climate change is already making wildfires more severe and this new research finds that it will lead to more days with high wildfire potential in areas already prone to wildfires, and create hotter and drier conditions that will expose entirely new areas. Understanding which areas are exposed to changing wildfire conditions will help leaders in government, finance and public health to mitigate catastrophic loss. This report explores Four Twenty Seven’s new methodology for assessing global wildfire potential, identifying regional trends and hot spots.

Download the report.

The 2019-2020 Australian bushfires raged for seven months, killed more than 30 people, hospitalized thousands more,[1] and burned more than 10 million hectares of land.[2] While the full financial and ecological impact is still unknown, costs from those fires are likely to exceed the $4.4 billion.[3] Meanwhile, ten of the largest wildfires in Arizona’s history occurred in the last eight years and nine of California’s largest wildfires occurred in just the last seven years.[4]

Beyond direct losses and disruption from damage to buildings and infrastructure, air pollution from wildfires has led to healthcare costs in excess of $100 billion in losses per year in the United States.[5] Leaders in government, finance, and public health need to understand how and where climate change will further heighten wildfire potential because of the serious threat wildfires pose to societies, economies, and natural systems.

This new report, Climate Change and Wildfires: Projecting Future Wildfire Potential, outlines Four Twenty Seven’s approach to quantifying global wildfire potential, capturing both absolute and relative changes in frequency and severity by 2030-2040.  Wildfire potential refers to meteorological conditions and vegetative fuel sources that are conducive to wildfires. Using a proprietary methodology submitted for peer review, our analytics link climate drivers such as changing temperature and precipitation patterns with the availability of vegetative fuels to assess wildfire potential in the future.

The analysis also explores key regions exposed to increasing wildfire potential and discusses the implications for financial stakeholders and communities. Our analytics affirm common understanding about locations exposed to wildfire, providing an indication of the increasing severity and frequency of wildfires in areas already prone to these events. The report also offers insight into areas that may have less obvious exposure, but are likely to have higher wildfire potential over time. Preparing for wildfires is a local, and often regional effort. The relatively high spatial granularity of our results (~25 kilometers) enables decision-makers to evaluate wildfire potential at a useful scale.

Key Findings:

  • Four Twenty Seven developed a first-of-its-kind global dataset projecting changes to wildfire potential under a changing climate, at a granularity of about 25 x 25 kilometers.
  • In areas already exposed to wildfires, by 2030-2040 climate change will prolong wildfire seasons, adding up to three months of days with high wildfire potential in Western Australia, over two months in regions of northern California and a month in European countries including Spain, Portugal and Greece.
  • New wildfire risks will emerge in historically wet and cool regions, such as Siberia, which is projected to have 20 more days of high wildfire potential in 2030-2040.
  • Globally, western portions of the Amazon and Southeast Asia will experience the largest relative increases in wildfire severity, further threatening crucial biodiversity hotspots and carbon sinks.
  • Confronting this new risk will take unprecedented resources and new approaches in regions not familiar with wildfires and worsening wildfire seasons will continue to threaten already limited resources in currently exposed areas.
