Oil Markets Brace for a New Iran Escalation After U.S. Midterms

The main danger is a possible widening of two connected conflicts: the U.S.-Iran war and the Saudi-Houthi confrontation. Oil traders fear fresh attacks could disrupt tankers near the Strait of Hormuz just as political pressure rises before the U.S. midterm elections.

October recorded more than 30 maritime incidents in Hormuz and nearby waterways, compared with 14 in September. A crude tanker was targeted inside Iraq’s exclusive economic zone, suggesting attacks are not limited to vessels secretly trying to cross Hormuz. The Houthis also claimed a missile strike on Saudi Arabia’s 550,000-barrel-per-day Ras Tanura refinery.

Diplomatic efforts by Qatar and Pakistan are temporarily limiting Brent’s rise near $115 per barrel. However, the Saudi-Houthi conflict appears increasingly self-sustaining. OPEC+ is expected to keep December output targets steady, while shipping costs, demurrage, and security risks remain elevated.

The Strait of Hormuz is a narrow maritime passage between the Persian Gulf and the Gulf of Oman. It connects major oil-producing states in the Gulf with international sea routes. Because tankers must use a limited passage, threats there can affect shipping far beyond the waterway itself.

The article highlights the route’s vulnerability through a sharp rise in attacks. More than 30 maritime incidents were recorded in October around Hormuz and surrounding waterways, up from 14 in September. A crude tanker was also targeted in Iraq’s exclusive economic zone, showing that danger extends beyond the strait’s immediate transit lanes.

This concentration makes insurance, security, freight, and waiting costs rise quickly. VLCCs made up 28% of drone and missile attacks in the Persian Gulf. If the route became harder to use, buyers would compete for alternative supplies and transport capacity, putting upward pressure on oil prices.

The recent escalation is large because attacks increased sharply in a single month. October brought more than 30 incidents in the Strait of Hormuz and surrounding waterways, compared with 14 in September. That rise indicates a more dangerous operating environment for vessels carrying crude and other cargoes.

The largest tankers have been particularly exposed. VLCCs, or very large crude carriers, accounted for 28% of all drone and missile attacks in the Persian Gulf. The article says 32 impacted ships represented almost 4% of the global VLCC fleet. A crude tanker was also targeted in Iraq’s exclusive economic zone.

The figures show that the risk is not confined to covert Hormuz crossings. UKMTO says reporting attacks is becoming harder because ships prefer to remain unnoticed. That may hide the full scale of incidents, while continued attacks threaten tanker availability and could tighten oil transport markets further.

Threats make Gulf oil more expensive to transport because shipowners and charterers must price in danger, delays, and limited vessel availability. A tanker may need extra security, wait for safer conditions, or accept a less direct and less predictable voyage. Those costs eventually enter the delivered oil price.

The article gives stark examples. Freight for a Saudi Arabia-China voyage is around $33 per barrel. Regional demurrage, the daily payment for keeping a vessel waiting, has risen since mid-August to $1 million per day. VLCCs have also suffered heavily, with 32 impacted ships.

The risk premium can grow even when no new attack occurs. UKMTO says ships increasingly prefer to sail unnoticed, while charterers fear pushing freight rates higher. If attacks continue, fewer owners may offer vessels, waiting times may lengthen, and buyers may pay more to secure Gulf barrels. That supports higher global oil prices.

Iran is central to the maritime risk because the article describes an eight-month U.S.-Iran war and escalating attacks around Hormuz. The possibility of renewed hostilities threatens vessels near a route used to move Gulf oil. Tehran is also the focus of diplomatic efforts seeking de-escalation.

The Houthis add a second front. They claimed a ballistic-missile strike on Saudi Arabia’s Ras Tanura refinery, which has capacity of 550,000 barrels per day. Saudi Arabia is therefore both a major source of Gulf oil shipments and a direct target in the Saudi-Houthi conflict. Earlier attacks reportedly shut the refinery for three months.

The United States is involved through the conflict with Iran and negotiations with Tehran. Qatar and Pakistan are trying to mediate between the Trump administration and Tehran. Washington is also considering extending a truce with China on port charges, a separate policy affecting shipping costs.

The article does not name alternative routes or replacement suppliers. In general, countries facing a dangerous Hormuz could reduce dependence on the strait by using pipelines to ports outside the affected area, alternative export terminals, and crude from producers in the Americas, Africa, the North Sea, or elsewhere.

The practical mechanism is substitution. Refineries can seek different grades of crude, while governments can release strategic reserves to cover temporary shortages. Some Gulf producers may also redirect barrels through pipelines where available. These options cannot automatically replace every shipment because pipeline capacity, port access, tanker availability, crude quality, and distance differ.

Such measures would probably cushion, rather than eliminate, the shock. Alternative routes may be longer or more expensive, and other suppliers may not have spare output. The article’s reported $33-per-barrel Saudi Arabia-China freight cost and $1 million daily demurrage show how quickly transport constraints can become costly.

A chokepoint concentrates transport risk. Even if oilfields elsewhere keep producing, barrels trapped behind a threatened route may not reach refineries on time. Traders price that possibility immediately because future supply matters as much as today’s production. The result can be a higher global benchmark price.

Hormuz shows the mechanism clearly. More than 30 incidents were recorded in October, and 32 impacted VLCCs represented almost 4% of the global VLCC fleet. Freight for a Saudi Arabia-China voyage is around $33 per barrel, while regional demurrage has reached $1 million per day. Shipping scarcity adds to the oil price.

The disruption does not need to close the strait completely. More security checks, rerouting, waiting, and reluctance by shipowners can reduce effective supply. Buyers then compete for safer routes, tankers, and alternative crude. That risk premium can lift Brent even while production in unaffected regions continues normally.
