01Lingkup

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?
02Konstruksi

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. Keterpaparan cuaca antariksa

    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. Kerapuhan infrastruktur

    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. Risiko siber

    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
    Ketergantungan listrik, telekomunikasi, keuangan, dan transportasi pada sinyal penentuan posisi dan waktu; jamming, spoofing, dan cuaca antariksa.

Status

Metodologi, struktur, dan definisi The Global Risks Index merupakan draf kerja persiapan (2026), yang diedarkan untuk ditinjau dan dikomentari, bukan untuk diterapkan. Tidak ada nilai yang ditampilkan sampai sebuah edisi dirilis dari pemotongan bukti yang diatur; nilai-nilai tersebut kemudian memuat interval, kelas, sumber, dan jalur koreksinya. Simulator menjalankan metode yang diterbitkan pada angka yang Anda pilih dan tidak pernah menampilkan nilai NXS-GRX.

Apa yang bukan NXS-GRX

NXS-GRX adalah informasi riset dan analitik risiko. NXS-GRX bukan peringkat kredit atau ESG dan tidak memakai skala peringkat, bukan acuan untuk instrumen keuangan, bukan statistik resmi, bukan peringatan darurat atau klasifikasi resmi, dan bukan nasihat. NXS-GRX tidak boleh digunakan untuk menilai orang perseorangan. Kelas risiko adalah pita pada skala yang diterbitkan, tidak pernah peringkat negara atau orang.

Lembaga dan sumber

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.

Setiap nilai memuat atribusi sumbernya, yang tetap memiliki lisensinya masing-masing. Nama-nama eksternal dikutip semata-mata untuk interoperabilitas. Teks yang disusun Nexus direncanakan berlisensi CC BY 4.0 saat dirilis.

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.
