01Ambito

Scope and questions

The subject of this index is proposed by NXS-GRX (canonical data, provenance and risk); the Nexus Reports edition with the same code sets its own subject at commissioning, and any difference is recorded as a crosswalk.

  1. Which systems fail without timing signals?
  2. How widespread is jamming and spoofing exposure?
  3. What backup exists?
02Construction

Domain indices to the series index

The series index is the expert-weighted geometric mean of its domain indices, with the intervals and class rule of the methodology.

  1. Esposizione alla meteorologia spaziale

    Domain index · IDX · SPC
    0–10 index of space-weather exposure as the product of the space-weather hazard and space-service dependence sub-indices; mostly modelled and expert inputs, so its grade is capped.
  2. Fragilità delle infrastrutture

    Domain index · IDX · INF
    Index of transport and digital connectivity deficits, utility fragility, energy supply unreliability and realised disruption impact on a 0–10 scale, higher meaning more fragile.
  3. Rischio cyber

    Domain index · IDX · CYB
    Index of cyber incident pressure, digital dependence and the lack of cyber capability on a 0–10 scale, higher meaning riskier.
  4. Positioning, navigation and timing index

    Series index · SERIES · XT-12
    Dipendenza di energia elettrica, telecomunicazioni, finanza e trasporti dai segnali di posizionamento e temporizzazione; disturbo, spoofing e meteorologia spaziale.

Stato

La metodologia, la struttura e le definizioni di The Global Risks Index sono una bozza di lavoro preparatoria (2026), diffusa per esame e commenti e non destinata all’attuazione. Nessun valore compare finché un’edizione non viene pubblicata a partire da un taglio di evidenze regolamentato; i valori riporteranno allora intervalli, classi, fonti e il relativo percorso di correzione. I simulatori applicano i metodi pubblicati ai numeri che scegli e non mostrano mai un valore NXS-GRX.

Che cosa non è NXS-GRX

NXS-GRX è un'informazione di ricerca e di analisi del rischio. Non è un rating creditizio o ESG e non usa alcuna scala di rating, non è un indice di riferimento per strumenti finanziari, non è una statistica ufficiale, non è un allerta di emergenza né una classificazione ufficiale e non è una consulenza. Non deve essere usato per valutare persone fisiche. Le classi di rischio sono fasce su una scala pubblicata, mai graduatorie di paesi o persone.

Istituzioni e fonti

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.

Ogni valore riporta l’attribuzione delle proprie fonti, che mantengono le rispettive licenze. I nomi esterni sono citati unicamente a fini di interoperabilità. I testi redatti da Nexus sono destinati alla licenza CC BY 4.0 al momento della pubblicazione.

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.
