One third of Gulf oil is still missing despite 'dark crossings', data shows - Reuters
Reuters · September 10, 2026 · Week 2026-37
Summary
Analysis of shipping data suggests a third of oil from the Gulf is untracked, likely due to 'dark' ship-to-ship transfers intended to evade international sanctions. This highlights the significant scale of illicit oil flows, complicating market analysis and sanctions enforcement, with strong implications for Iranian crude exports.
Strategic Implication
The scale of untracked 'dark fleet' activity highlights the porosity of sanctions regimes and complicates OPEC+ efforts to manage global oil supply, creating a persistent source of downward pressure on prices.
