Embedding climate risk into sector lending decisions
An illustrative bank translates climate scenarios into sector heatmaps, borrower questions, and a staged governance plan.
The challenge
The illustrative bank understood climate risk conceptually but lacked a proportionate method for connecting physical and transition drivers to borrower assessment and portfolio oversight.
The work
- 01Selected scenarios and time horizons that matched the bank's planning and credit cycles.
- 02Combined sector transition sensitivity with geographic exposure to heat, water stress, and flooding.
- 03Designed borrower prompts, escalation criteria, governance roles, and training for relationship and credit teams.
The result
The hypothetical framework gives risk teams a consistent screening method while reserving deeper assessment for material exposures.
This illustrative engagement is not presented as a real Climate assignment. Names, figures, and results are fictional and intended to show a credible delivery model.
Rather than create a single portfolio score, the approach separated physical hazard, vulnerability, transition pressure, and financial materiality. This made the heatmap more useful for credit decisions and avoided masking different risk mechanisms.
Pilot workshops tested the method against representative borrower profiles. Feedback from relationship managers simplified the evidence request and clarified when a specialist review should be triggered.
The roadmap staged implementation across governance, screening, data, scenario analysis, and disclosure so the bank could build capability without delaying near-term decisions.
