The Global Risk Report 2026 of the World Economic Forum:

Methodology:

The Global Risks Perception Survey (GRPS) is the World Economic Forum’s source of original risks data, harnessing the expertise of the Forum’s extensive network of academic, business, government, international organization, civil society and other decision-makers and thought leaders. Survey responses were collected from 12 August to 22 September 2025.

Short- and long-term risks landscape asked respondents to estimate the likely impact (severity) of each of the 33 global risks, on a 1-7 scale [1 = Low severity, 7 = High severity], over both two-year and 10-year periods. “Severity” is meant to take into consideration the impact on populations, the economy or environmental resources on a global scale. Respondents were also allowed to nominate any other risk considered missing from the 33 risks. A simple average based on the scores selected was calculated and the results are illustrated in Chapter 1, Figure 10.
