Climate Change Risks Exacerbate Banking Sector Vulnerabilities, Urgent Action Needed

As concerns mount over the impact of climate change on global financial stability, a coalition of investors has sounded the alarm on the vulnerabilities faced by banks. In a recent letter to the Bank of England (BoE), investors highlighted the urgent need for stronger regulations to address the growing climate-related risks facing the banking sector.

The letter, signed by prominent investors including major pension funds and asset managers, warns that banks may not be adequately prepared to cope with the escalating effects of climate change. It underscores the multifaceted nature of climate-related risks, ranging from credit and physical risks to regulatory and reputational challenges.

Credit risks emerge as businesses in climate-vulnerable sectors face financial distress and default on loans due to extreme weather events and regulatory changes. Meanwhile, physical risks pose threats to banks’ infrastructure and collateral value, with rising sea levels, floods, and wildfires causing property damage and business interruptions.

Transition risks loom large as the shift to a low-carbon economy necessitates the revaluation of high-carbon assets and investments. Regulatory pressures, including stricter capital requirements and disclosure standards, further compound the challenges faced by banks in managing climate risks effectively.

The investors advocate for tougher regulations to compel banks to factor climate risks more comprehensively into their operations. They call for enhanced capital requirements to protect against systemic climate risks, urging the BoE to issue explicit guidance for banks to use severe yet plausible climate scenarios in their risk assessments.

Furthermore, the investors emphasize the importance of transparent disclosure of key findings from climate stress-testing exercises to enhance market transparency and investor confidence. They stress the need for collaborative efforts between regulators, banks, and investors to address the systemic risks posed by climate change effectively.

While recognizing the BoE’s pioneering efforts in acknowledging the financial stability risks associated with climate change, the investors express concern over the removal of climate change from the central bank’s key priorities. They urge the BoE to maintain its leadership role in driving the transition to a net-zero economy and ensuring the resilience of the banking sector.

The letter underscores the critical role of financial regulators in addressing climate-related risks and fostering a more resilient and sustainable financial system. With climate change posing an existential threat to global economies, urgent action is needed to mitigate its adverse effects on the banking sector and safeguard financial stability for future generations.
