End to end on the longest path: about 5.1 d of proposed target service levels. Gates wait for the people named; bars with a fading end have no fixed length.

Compose an index for a portfolio, sector, city or supply chain on the Indicator Standard grammar, with the same uncertainty, tests and provenance as NXS-GRX itself. The canvas shows where a request stands at the marked job; it is illustrative, not the status of a real request. Durations are proposed target service levels. Select a job for its steps, the people who act, the technology it runs on and what it produces.

Series most read

GLBGlobal SystemsThe state of interdependent global risk: the twenty domain indices aggregated to the world, the five core systems (water, energy, food, health, biodiversity) and their couplings, the global tail register and the gap between perceived and measured risk. GS-01Global WaterAccess, scarcity, quality, floods and droughts, groundwater depletion, transboundary dependency and the couplings of water to energy, food, health and nature. GS-02Global EnergySupply adequacy, import dependency, grid reliability, affordability, extreme-weather exposure, critical minerals and transition pathways. GS-03Global Food and agrifoodAcute and chronic food insecurity, production shocks, import dependency, prices, fertiliser and logistics chokepoints, nutrition and pollination dependency. GS-04Global HealthHealth security capacity, epidemic emergence and spread, heat and air-quality burden, health system stress and access. GS-05Global Finance and economyFiscal and public debt risk, financial stability, external dependence, inflation and growth at risk, and the macro-financial channels of physical and transition risk. GS-06Global DevelopmentPoverty, inequality, human development, demographic pressure and displacement as the ground on which shocks become losses. GS-07Global ClimateChronic and acute physical climate hazard, transition exposure, adaptation gaps and scenario pathways to 2030, 2050 and 2100. GS-08Global DisasterMulti-hazard exposure, disaster losses and mortality, return-period losses, protection gaps and coping capacity.

Statut

La méthodologie, la structure et les définitions de The Global Risks Index constituent un projet de travail préparatoire (2026), diffusé pour examen et commentaires et non pour mise en œuvre. Aucune valeur n'apparaît avant la publication d'une édition à partir d'une coupe de données probantes encadrée ; les valeurs comportent alors des intervalles, des classes, des sources et leur voie de correction. Les simulateurs appliquent les méthodes publiées à des nombres que vous choisissez et n'affichent jamais de valeur NXS-GRX.

Ce que NXS-GRX n'est pas

NXS-GRX est une information de recherche et d'analyse des risques. Ce n'est pas une notation de crédit ou ESG et il n'utilise aucune échelle de notation ; ce n'est pas un indice de référence pour des instruments financiers, ni une statistique officielle, ni une alerte d'urgence ou une classification officielle, ni un conseil. Il ne doit pas servir à évaluer des personnes physiques. Les classes de risque sont des bandes sur une échelle publiée, jamais des classements de pays ou de personnes.

Les signaux Pulse et les probabilités de perspective sont des informations soumises à l'examen des autorités compétentes, jamais des alertes publiques ; les alertes officielles viennent uniquement des autorités mandatées.

Institutions et 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.

Chaque valeur porte l'attribution de ses sources, qui conservent leurs propres licences. Les noms externes ne sont cités qu'à des fins d'interopérabilité. Les textes rédigés par Nexus sont destinés à être publiés sous licence CC BY 4.0.
