Durum
The Global Risks Index’in metodolojisi, yapısı ve tanımları, uygulama için değil, inceleme ve yorum için dolaşıma sunulmuş hazırlık niteliğinde bir çalışma taslağıdır (2026). Bir sürüm yönetilen bir kanıt kesitinden yayımlanana kadar hiçbir değer görünmez; değerler o zaman aralıkları, sınıfları, kaynakları ve düzeltme yollarını taşır. Simülatörler yayımlanan yöntemleri sizin seçtiğiniz sayılarla çalıştırır ve asla bir NXS-GRX değeri göstermez.
NXS-GRX ne değildir
NXS-GRX bir araştırma ve risk analitiği bilgisidir. Kredi ya da ESG derecelendirmesi değildir ve derecelendirme ölçeği kullanmaz; finansal araçlar için gösterge, resmî istatistik, acil durum uyarısı ya da resmî sınıflandırma ve tavsiye değildir. Gerçek kişileri değerlendirmek için kullanılmamalıdır. Risk sınıfları yayımlanmış bir ölçek üzerindeki bantlardır, asla ülkelerin ya da kişilerin sıralaması değildir.
Kurumlar ve kaynaklar
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.
Her değer, kendi lisanslarını koruyan kaynaklarının atfını taşır. Harici adlara yalnızca birlikte çalışabilirlik amacıyla atıf yapılır. Nexus tarafından yazılan metinlerin yayımlandığında CC BY 4.0 kapsamında olması amaçlanmaktadır.
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.
