Oil Rises as US Completes Iran Strikes Near Key Chokepoint

The direct threat is not an Iranian blockade by force. Mines or ship attacks could disrupt tanker traffic. The bigger risk is insurance and freight markets. Tanker operators and their insurers are already pricing in a higher war-risk premium. That raises delivered crude costs and widens the spread between physical barrels and benchmark futures.

That spread jumped in early trading. Traders who watch the Brent-WTI spread saw it widen by nearly a dollar. The forward curve also started to steepen, signaling the market expects the disruption to last.

Rystad’s 11.8 million barrel daily loss dwarfs the 2019 Abqaiq-Khurais attacks, which knocked out about 5.7 million barrels a day for a few weeks. That event pushed Brent above $75 before Saudi Aramco restored output within days. This time the losses are cumulative and spread across multiple producers, making a quick restart harder.

The consultancy’s warning of 350 million barrels per additional month implies the market would need to draw inventories at an unprecedented pace. The International Energy Agency last reported commercial stockpiles in OECD countries at about 2.8 billion barrels. Every month of conflict at that rate consumes over 12% of those stocks.

Next Markers: Inventories and Iran’s Response

The first concrete marker is the weekly U.S. inventory report due Thursday. A large draw in crude stocks would confirm that physical supply tightness is already reaching the market. The second marker is any sign of expanded Iranian retaliation, which would increase the risk of a broader tanker insurance exclusion zone.

For now the oil complex is pricing in a near-double-digit percentage risk premium. That premium will stay until either the U.S. and Iran signal de-escalation or a confirmed barrel loss shows up in export data. Traders should watch the Brent-WTI spread and the forward curve for signs of backwardation deepening. That would signal the market expects the disruption to last.
