상태
Global Risks Index의 방법론, 구조, 정의는 검토와 의견 수렴을 위해 배포된 예비 작업 초안(2026)이며 이행용이 아닙니다. 관리되는 근거 마감에 따라 판이 공개되기 전까지는 어떠한 값도 표시되지 않으며, 공개 후 값에는 구간, 등급, 출처, 정정 경로가 함께 표시됩니다. 시뮬레이터는 귀하가 선택한 숫자에 공개된 방법을 적용할 뿐이며 NXS-GRX 값을 표시하지 않습니다.
NXS-GRX가 아닌 것
NXS-GRX는 연구 및 리스크 분석 정보입니다. 신용등급이나 ESG 등급이 아니며 등급 척도를 사용하지 않고, 금융상품의 벤치마크도, 공식 통계도, 긴급 경보나 공식 분류도, 자문도 아닙니다. 자연인 평가에 사용해서는 안 됩니다. 리스크 등급은 공개된 척도 위의 구간이며, 국가나 사람의 순위가 결코 아닙니다.

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.
