The article ranks economic sanctions against Iran based on their impact on the economy. Using expert opinions and a method called fuzzy AHP, the study found that UN financial-banking sanctions pose the highest threat, followed by UN oil sanctions and EU financial-banking sanctions. These sanctions make up over 78% of the total hazard to the Iranian economy. US sanctions, on the other hand, contribute to only 15% of the overall threat. This suggests that UN/EU financial-banking and oil sanctions are more significant and should be a focus in policy-making.
