ステータス
The Global Risks Index の手法、構造、定義は準備段階の作業草案(2026 年)であり、レビューと意見募集のために配布されているもので、実施を目的としたものではありません。管理されたエビデンスの区切りから版が公表されるまで、値は一切表示されません。公表後の値には、区間、区分、出典、訂正の経路が付されます。シミュレーターは、公表された手法をあなたが選んだ数値で実行するものであり、NXS-GRX の値を表示することはありません。
NXS-GRX ではないもの
NXS-GRX は研究およびリスク分析の情報です。信用格付や ESG 格付ではなく、格付尺度を用いず、金融商品のベンチマークでも、公的統計でも、緊急警報や公式分類でも、助言でもありません。自然人の評価に用いてはなりません。リスククラスは公開された尺度上の区分であり、国や人の順位付けではありません。
機関と情報源
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.

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.
