I3E Economic Uncertainty Index

The I3E Economic Uncertainty Index is a leading daily indicator of economic uncertainty across major world economies. Developed by IESE and the International Center for Decision Making, the I3E Index combines stock market volatility, bond yields, exchange rates, and oil prices into a transparent and objective measure.

Researchers, policymakers, and businesses use the I3E Index to track changes in economic risk and uncertainty worldwide. Explore global trends, download open data, and compare uncertainty across countries.

Why measure economic uncertainty?

Economic uncertainty impacts investment, employment, and policymaking worldwide. The I3E Economic Uncertainty Index offers a quantifiable and bias-free benchmark for comparing uncertainty levels across nations, providing invaluable insight for research and decision-making.

How is the I3E Economic Uncertainty Index calculated?

The index is computed daily, using the variation rates of four key variables in each country:

• Domestic Stock Index
• Domestic 10-year government bond yields
• Domestic exchange rate
• International Brent crude oil prices

The index has an average value of 100. Although it can vary across any range, in practice it fluctuates between 0 and 200. Values below 100 indicate uncertainty lower than the average of previous decades. Values above 100 indicate greater uncertainty.

The I3E provides a quantifiable and bias-free measure of economic uncertainty that may be used by researchers and decision-makers worldwide.
