**Summary**: Satellite imagery shows a large oil slick around Iran’s Kharg Island with no tankers observed near the terminal for four days. Given Kharg handles roughly 90% of Iran’s crude exports, this points to an operational halt and raises the probability that flows are already disrupted, adding to existing geopolitical risk around prospective US–Israel strikes on Iran.

## Detail

1) What happened:
CNN, citing satellite imagery, reports a large oil slick spreading in the area of Kharg Island, Iran’s primary crude export terminal, from which around 90% of Iranian oil exports are shipped. Crucially, no oil tankers have been observed near the island in the last four days, suggesting loadings are currently suspended or severely curtailed. Iranian opposition channels additionally claim significant ecological damage.

2) Supply impact:
Iran’s crude exports are broadly estimated in the 1.4–1.8 mb/d range in recent months, the majority via Kharg. A complete halt at Kharg, even if partially offset by alternative terminals, implies an immediate downside risk of ~1–1.5 mb/d to seaborne supply if the disruption is physical and persistent, not just precautionary. Even a perceived temporary outage of several hundred kb/d, combined with rising war risk, is sufficient to move flat price and time spreads notably.

3) Affected assets and direction:
– Brent and WTI: Bullish. Expect upward pressure on front-month contracts and tightening of prompt spreads as traders price potential loss of Iranian barrels and higher risk premium in the Gulf.
– Dubai/Oman benchmarks and Middle East sour grades: Bullish relative to Atlantic grades given direct exposure to Iranian flows.
– European and Asian refining margins for sour crudes: Likely to widen; Asian importers (China, some smaller buyers) may face tighter availability of discounted Iranian barrels.
– Tanker equities and ME Gulf war-risk insurance premia: Moderate bullish bias as operational risk to Gulf loadings rises.

4) Historical precedent:
Comparable market reactions occurred during the 2019 Abqaiq–Khurais attack in Saudi Arabia (sharp spike, then partial retracement) and various phases of Iran sanctions tightening, where even anticipated supply losses of 0.5–1.0 mb/d materially lifted Brent.

5) Duration and structure:
Near-term, this is a high-impact, high-uncertainty, risk-premium event. If the slick reflects sabotage or kinetic damage to loading infrastructure, repairs could take weeks, making the disruption more structural. If instead it is a contained spill with voluntary loading pause, physical impacts may be measured in days, but the geopolitical risk premium linked to vulnerability of Kharg and concurrent US–Israel strike planning could persist for months, keeping volatility and backwardation elevated.
