Climate & Catastrophe Risk

Climate risk quantification for balance sheets that carry it: physical and transition scenarios, catastrophe frequency-severity models with heavy-tail (GPD) calibration, and integration into ORSA, ICAAP, and IFRS 9 forward-looking overlays.

Outcomes you can expect

  • A climate view your risk committee understands and can act on
  • Catastrophe frequency-severity models with defensible tails
  • Regulatory climate disclosures that don't require re-work each cycle

Typical engagements

  • NGFS / bespoke climate scenario translation into financials
  • Physical and transition risk quantification by portfolio
  • Catastrophe frequency-severity modelling and GPD tail calibration
  • ORSA / ICAAP climate integration and disclosure support
