The Fed's Pilot — Are Banks Prepared for the Climate Transition?
- Corporate loans of the six U.S. banks participating in the Federal Reserve's pilot climate scenario-analysis exercise currently contribute to over 90% of the total emissions of their lending exposures.
- Using MSCI Climate-Adjusted Probabilities of Default estimates, we found that the transition-risk-adjusted probability of default of an average corporate-loan portfolio would rise 95 basis points under a "net-zero 2050" scenario.
- The six banks' latest Task Force on Climate-related Financial Disclosures reports indicate that some are more advanced than others in the use of climate risk measurement approaches to inform business decisions.
Comparing the biggest US banks' credit exposures and climate-transition risks
The loan portfolios of the six in-scope banks vary in size, ranging from Goldman Sachs' USD 184.8 billion to JPMorgan's USD 1.1 trillion, as at the end of 2022. Bank of America and Wells Fargo had the biggest corporate and commercial-real-estate portfolios, respectively. While corporate portfolios on average accounted for less than half (44%) of the banks' loan books, they contained loans from carbon-intensive sectors such as energy, utilities and mining. Our estimation5 suggested that corporate loans contributed to more than 90% of the banks' total greenhouse-gas emissions associated with lending. Among the six banks, Morgan Stanley had the highest percentage of loans concentrated in the energy and utilities sectors (5.5%).
How loan balances and emissions broke down by bank
Loan-balance breakdown is based on banks' public disclosures for fiscal year 2022. Emission data includes Scope 1 and 2 financed emissions for each loan segment (quality score of 5) and was calculated using the MSCI Total Portfolio Footprinting solution, which follows the Partnership for Carbon Accounting Financials (PCAF) principles.

Based on MSCI Climate-Adjusted Probabilities of Default6 estimates, the annualized PD of an average corporate-loan portfolio (using the MSCI ACWI Investable Market Index weighted by enterprise value including cash, or EVIC, as a proxy) would gradually increase over time, reaching 0.29% by year 10 under current policies (baseline).
Under different NGFS scenarios, however, transition risks will have different credit impacts, including changes in costs associated with reducing emissions and revenues generated by developing low-carbon technologies. And through these changes, we found that the forecast PD term structure changed significantly.
In the "net-zero 2050" scenario,7 the transition-risk-adjusted PD immediately rose to 1.03% under the assumption that all expected future climate costs would be priced in instantaneously. Meanwhile, the annualized PD decreased over time, reaching 0.51% by year 10 as companies' valuation dynamics were conditional on survival.8

Each company's transition-risk-adjusted PD change was calculated based on the downside policy-risk exposure according to all emission sources (Scopes 1, 2 and 3) and upside technology-opportunity exposure.

Banks' current approaches to managing climate-related financial risks
In addition to providing credit-risk projections, the six banks must also respond to qualitative questions on governance and risk management practices to help the Fed understand their current approaches and challenges in evaluating climate-related financial risks. Our analysis of the banks' most recent Task Force on Climate-related Financial Disclosures (TCFD) reports indicated that all the banks have developed their own environmental credit policies related to oil and gas and power utilities. They were, however, at varying stages of developing and using climate-risk measurement approaches to inform business decisions. For example, Wells Fargo noted it uses climate scenario analysis to set enterprise-level targets for net-zero in 2050 and interim 2030 sector targets, while Bank of America and Citigroup disclosed that they are beginning to integrate the results into firmwide risk management and capital planning.

The Fed is expected to publish findings from the pilot by the end of this year. While expectations for banks to develop their approaches to measuring climate risk grow, investors will likely focus on how prepared banks are to weather the impact of the low-carbon transition.
