Hear from Hirotaka Hideshima, former central banker and member of the TNFD, as we explore the parallels between financial risk, nature risk and regulation.

What happens when a central banker steps into the world of nature risk? Well, they can see parallels between financial risk and nature risk that aren’t obvious to others. For example, just as the global financial crisis exposed systemic vulnerabilities in banking, nature loss poses systemic risks that today’s models and disclosures struggle to capture.

And although the Basel framework and the Taskforce on Nature-related Financial Disclosures (TNFD) recommendations are very different, they do share one key underlying objective — that is, to internalize externalities that markets fail to price. In this episode, we explore what a 30-year career in financial regulation can tell us about nature risk, including:

Why risk professionals must consider the long-term materiality of nature risk, even when short-term impacts may appear limited;
Practical first steps for incorporating nature into credit risk processes and operational resilience planning; and
The role of qualitative judgment when models cannot fully capture environmental externalities.
