Sustained Disruption of Iranian Crude Exports Via Kharg Drives Additional 3–8% Upside in Oil

Executive summary
Within a week, confirmation that Kharg Island’s export operations are materially impaired—whether from environmental damage, interdiction, or technical failure—is likely to add another 3–8% upside pressure to Brent and Middle East benchmarks from current levels. Market participants will reassess Iran’s near-term export capacity, factoring in existing US-led interdictions and stricter shipping rules. If Iranian volumes drop meaningfully for more than several days, backwardation in the crude curve will steepen and Asian refiners will seek alternative supplies, bumping up demand for Saudi, Iraqi, and Russian barrels. Volatility will remain elevated on speculation of sabotage versus accident.
