REM Working paper series, nº 0384/2025http://hdl.handle.net/10400.5/102503This paper tackles the urgent issue of how tensions in energy transportation impact oil markets and the global economy. The study introduces an energy transportation uncertainty index, developed from over 50 global newspapers, to monitor fluctuations in uncertainty associated with significant events such as the Tanker War, major US sanctions, the Exxon Valdez oil spill, the Nord Stream sabotage, the Colonial pipeline cyberattack, and various Gulf incidents. Using a structural vector autoregression (SVAR) model, the analysis shows that these fluctuations in transportation uncertainty cause increases in real oil prices due to supply chain challenges. While oil production dips initially due to perceived risks, it quickly rebounds, though inventories are heavily used. These shocks also heighten geopolitical tensions and reduce global industrial output.engSupply chain disruptionsEnergy transportation uncertaintyGeopolitical risksOil marketsUncertainty shocksSVARworking paper
