Climate Change

Climate-related risks are increasing due to the lack of a coordinated global response by governments to combat climate change and restrict temperature increases to 1.5 degrees Celsius.
 

Countries are undergoing green transitions at different paces, exacerbating the risks associated with a disorderly global transition. Climate change poses significant economic and social risks. In this context, central banks face higher risks to financial and price stability. There is more urgency to increase the resilience of financial systems to climate-related shocks and ensure strong monetary policy credibility to address larger and more persistent price shocks.

While the primary tools for adaptation to, and mitigation actions against, climate change are vested with government departments, the South African Reserve Bank (SARB) has the important role of maintaining price and financial stability in the face of rising climate-related risks.

The SARB is focused on:

  • ensuring that financial institutions and markets consider climate-related risks in their operations; 
  • understanding the impacts of climate change on inflation and financial stability and taking appropriate actions to mitigate against these risks; and
  • greening its own operations. 

The SARB’s climate change workstreams are coordinated by a steering committee and managed by different departments in the central bank.

The SARB’s climate strategy and work programme is guided by the recommendations of theNetwork for Greening of the Financial System (NGFS), the Sustainable Insurance Forum (SIF), the Financial Stability Board and the Group of Twenty. In January 2024, Deputy Governor Fundi Tshazibana was announced as the Vice Chair of the NGFS (until June 2026), and in December 2025 as Chair of the SIF. Locally, the SARB closely coordinates its work with National Treasury and regulators through the Intergovernmental Sustainable Finance Working Group.

The South African Reserve Bank recognises the critical need to integrate environmental, social and governance (ESG) principles into its investment operations - ensuring that the SARB’s investment portfolios are managed with a focus on ethical considerations and long-term societal impact. To ensure that sustainable and responsible investment considerations are central to the management of the SARB’s investment portfolios, the SARB compiled an environmental, social and governance (ESG) Charter. The ESG Charter is included in Annexure F of the SARB Gold and Foreign Exchange Reserves Management Investment Policy (Investment Policy). 

The SARB conducted a Climate Risk Stress test (CRST) in 2024 as an exploratory macroprudential stress test that subjected systemically important South African banks to a set of plausible, long-term climate-related scenarios. The objective of the CRST was to test the resilience of the banking sector to physical and transition risks and to assess banks’ data and methodological processes for considering climate-related risks. The results are presented in the First Edition 2025 Financial Stability Review which is accompanied by a Technical Report: 2024 Climate Risk Stress Test which details the CRST design, top-down credit modelling framework, and scenario approaches.
