FCA Taps TREX for Innovative Climate Risk Analysis via Regulatory Sandbox

Quick Summary

The FCA is partnering with Transition Risk Exeter Ltd (TREX) to pilot climate risk analysis through its Regulatory Sandbox. This initiative helps financial firms quantify the impact of extreme weather events and transition risks, ensuring more resilient investment decisions as the UK scales its sustainable finance capabilities.

How Does TREX Improve Climate Risk Analysis for Firms?

Transition Risk Exeter Ltd (TREX) provides a sophisticated approach to climate risk analysis by focusing on non-linear scenario analysis. Unlike traditional models, TREX evaluates how climate tipping points and compounding risks—such as back-to-back storms or heatwaves—can trigger rapid knock-on effects across financial systems. This is critical given that in 2025, extreme weather contributed to 92% of global insured losses.

• Physical Risk Assessment: Detailed modeling of flooding, wildfires, and heatwaves.
• Transition Risk Mapping: Analyzing the financial impact of moving toward a low-carbon economy.
• Granular Data: Risk profiling at the country, sector, and individual company level.

What is the Role of the FCA Regulatory Sandbox in This Pilot?

The FCA Regulatory Sandbox provides a controlled environment for TREX to validate its models with rigorous evidence. By testing these innovative tools, the FCA aims to complement existing tools with new models that offer a clearer view of systemic vulnerabilities. Since its inception in 2014, the sandbox has been replicated by 95 global regulators, proving its efficacy in fostering financial innovation.

Willemijn Verdegaal, co-founder & chief product and commercial officer, TREX said:

“This FCA Sandbox gives us the opportunity to demonstrate, with rigorous evidence, how non‑linear scenario analysis – which explores how climate-related risks can escalate rapidly or trigger knock‑on effects – changes the risk and opportunity profile at country, sector and company level, enabling more resilient investment decision-making. We're excited to be working with the FCA and industry partners to deliver long-term impact in this space.”

What Future Climate Initiatives is the FCA Planning?

Beyond the TREX partnership, the FCA is launching a dedicated climate scenarios cohort later this year. This specialized sandbox will invite firms to test high-impact risks and reverse stress testing. The goal is to improve the quality and consistency of climate-related information available to the market, supporting the UK's ambition to be a global sustainable finance hub.

FF NEWS TAKE:

This collaboration marks a significant shift from theoretical climate risk analysis to actionable financial data. By integrating TREX into the Regulatory Sandbox, the FCA is acknowledging that current models often underestimate compounding climate risks. This move definitely moves the needle; it forces financial institutions to look beyond linear projections and prepare for the 92% loss reality seen in recent years. It is a vital step for UK market stability.
