Basel Committee makes climate risk disclosure for bank regulators voluntary

The Basel Committee on Banking Supervision released its framework for disclosing climate-related risks, but implementation will be voluntary due to pushback from the U.S. The framework asks banks to identify and respond to climate-related impacts on their finances, considering both physical and transition risks; however, the voluntary nature and removal of facilitated emissions reporting requirements mark a significant scaling back from the original proposal, reflecting diverging global approaches to integrating climate risk into financial regulation, particularly between Europe and the U.S.

Analysis

The Basel Committee on Banking Supervision has released a framework for climate-related risk disclosure for banks, designating its implementation as voluntary due to significant pushback, notably from the United States. This decision contrasts with European regulators, such as the European Central Bank, which are prioritizing climate risk management. The framework encourages banks to identify and outline responses to both physical risks, like flooding, and transition risks, such as policy changes affecting agriculture. However, the final version, following a consultation on the November 2023 proposal, now omits the requirement for banks to report on 'facilitated emissions'—those linked to their capital markets and trading activities. The committee cited the evolving nature of climate-related data accuracy and consistency as a reason for incorporating flexibility. This development underscores a growing divergence in global regulatory approaches to climate risk, with the U.S. scaling back on such initiatives, evidenced by the Federal Reserve's withdrawal from the Network of Central Banks and Supervisors for Greening the Financial System (NGFS) and U.S. commercial banks dropping climate targets. The Basel Committee intends to monitor global developments and may consider future revisions to the framework.

Key Decisions for Investors

• Investors should anticipate continued divergence in climate-related disclosure requirements for banks globally, particularly between Europe and the U.S., which may affect comparability and risk assessment across portfolios.
• Given the voluntary nature of the framework and the exclusion of 'facilitated emissions' reporting, investors focused on ESG factors may need to rely on supplementary data sources and direct engagement to assess the full spectrum of climate-related risks within banking investments.
• Monitor for any future revisions to the Basel framework or shifts in U.S. regulatory policy, as these could significantly alter disclosure expectations and impact the banking sector's approach to climate risk management.
