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.

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.
