FCA Sandbox Welcomes TREX for Climate Risk Testing

The Financial Conduct Authority has accepted Transition Risk Exeter Ltd into its regulatory sandbox. TREX will test new tools for climate scenario analysis. This step aims to give financial firms better insights into physical and transition risks.

Key Facts

• FCA onboarded TREX into the regulatory sandbox on 26 June 2026.
• TREX tests climate scenario analysis for physical risks such as flooding and heatwaves.
• The approach also covers risks from the shift to a low-carbon economy.
• Financial firms may gain clearer views of climate-related exposures.
• The sandbox allows live testing under FCA supervision.

Simple Breakdown

The regulatory sandbox lets firms try new ideas with real customers but under close watch. Climate scenario analysis means running models that show what could happen under different future climate paths. Physical risks include direct damage from weather events. Transition risks arise when economies move away from high-carbon activities. TREX wants to combine both types of risks into one clear picture for banks and insurers.

Why This Matters

Banks and insurers need accurate data to set aside enough capital for possible losses. Better models can help them price loans and insurance more fairly. Clearer risk views may reduce surprises during extreme weather or policy changes. This work supports steady financial services even as climate conditions shift.

What's Next

Results from the sandbox test will shape how other firms build climate tools. Regulators may update guidance based on what TREX learns. Wider use of these models could become standard practice within a few years.

Conclusion

Firms should watch for early lessons from the TREX test. Updated risk tools may soon reach more users. Continued sandbox work keeps regulation in step with new needs.
