Every risk method, standardised
670 methods across hazard science, exposure, vulnerability, loss, catastrophe, financial, sovereign, systemic, climate, health, cyber and assurance, each with a stable ID, an honest implementation state and the standards that govern it.
23 method fabrics
Every quantitative method the index and its platform may use is registered once, in one fabric, with a stable capability ID; a title is display text only.
What is implemented
169 capabilities are bound to hand-written scientific kernels with golden-value tests in Python, Julia or R. Every capability is release-held, with a supported claim level of integrated.
- Connected
- An existing governed engine path is available; specialist physics still needs validation for the context of use.
- Reference implementation
- Transparent reference mathematics for diagnostics and parity, not institutional-grade calibration.
- Adapter required
- Registered; an execution adapter is still to be built. Requests fail closed.
- Specialist model required
- Needs a specialist domain model. Requests fail closed rather than fabricate an output.
- Data required
- Needs governed data that is not yet available. Requests fail closed.
What every method must carry
The same contract applies to an NXS-GRX (canonical data, provenance and risk) index, a custom index in Index Studio and a model run in Model Lab.

What registration does not mean
- Capability registration is not model execution, calibration, observation, validation or assurance.
- CONNECTED means an existing governed engine path is available; specialist domain physics still requires context-of-use validation.
IMPLEMENTED_REFERENCEmeans transparent reference mathematics exists for diagnostics/parity, not institutional-grade calibration.SPECIALIST_MODEL_REQUIREDandDATA_REQUIREDfail closed rather than fabricate outputs.- Cryptographic integrity proves the network's own records relationships, not scientific truth.
Comment on the methodology
Open consultation on normalisation, weighting, aggregation, imputation, uncertainty and validation; every comment receives a disposition in the consultation record.
- 01Fill inFields marked (required) are needed; everything else helps the review.
- 02ReferenceYou get a reference on screen; the record is kept in this site’s WordPress database.
- 03ReviewThe outcome is recorded in public. Contact details stay on this site and are never published or shared.
This form opens here once it is switched on. Until then, send it through the Nexus Reports gateway.
Propose a method
New methods are registered with a stable ID, a hand-derived golden test and their evidence obligations before any page uses them.
Imeko
The methodology, structure and definitions of The Global Risks Index are a preparatory working draft (2026), circulated for review and comment and not for implementation. No value appears until an edition is released from a governed evidence cut; values then carry intervals, classes, sources and their correction pathway. Simulators run the published methods on numbers you choose and never show a NXS-GRX value.
What NXS-GRX is not
NXS-GRX is research and risk-analytics information. It is not a credit or ESG rating and uses no rating scale, not a benchmark for financial instruments, not official statistics, not an emergency warning or official classification, and not advice. It must not be used to evaluate natural persons. Risk classes are bands on a published scale, never rankings of countries or people.
Institutions and sources
The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.
Every value carries the attribution of its sources, which keep their own licences. External names are cited for interoperability only. Nexus-authored text is intended for CC BY 4.0 on release.
Avis en français
La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
