Direct Answer
BCBS and IAIS are two global supervisory reference points for climate-related financial risk in banking and insurance. The Basel Committee’s voluntary disclosure framework addresses climate-related financial risks for banks, including qualitative and quantitative information. The IAIS Application Paper helps insurance supervisors integrate climate-related risks into supervisory practices. For ClimaTwin, these frameworks matter because physical hazards can affect loan collateral, insurance claims, underwriting, reserves, investments, operations, concentration risk, and financial resilience. The common theme is that climate risk must be measured, governed, monitored, and disclosed in a financially meaningful way.
How It Works
The five supervisory evidence areas are:
- Governance and accountability for climate-related financial risk.
- Strategy and business-model resilience under physical risk scenarios.
- Risk management processes for identifying, measuring, monitoring, and controlling exposures.
- Qualitative disclosures that explain practices, assumptions, and limitations.
- Quantitative indicators that help supervisors and markets understand exposure, concentration, and potential impact.
ClimaTwin’s Climate Business Intelligence™ supports these areas by linking climate hazards to loan books, insured assets, real estate, infrastructure, operational sites, scenario ranges, and financial consequences.
Limitations
BCBS and IAIS materials are supervisory frameworks and guidance, not a single global compliance checklist. Implementation depends on jurisdiction, regulator, institution type, proportionality, and local rules. Physical risk analytics must align with each institution’s risk taxonomy, controls, data governance, and supervisory expectations.
