Brent crude has traded above $100 a barrel for most of the past three weeks, a level the global benchmark keeps returning to as Washington moves more military assets toward the Middle East and shippers report fresh attacks on tankers transiting the Strait of Hormuz.
The benchmark swung sharply this week, touching roughly $106 a barrel in one volatile session — a jump of as much as 5.7% intraday — before paring back below $103, according to Trading Economics. The spike followed reports that a third U.S. aircraft carrier strike group is being dispatched to the region, alongside Marine Corps units and as many as 10,000 additional troops, with the buildup expected to be complete by the end of November. Separately, Gulf News reported the Brent-WTI spread widening past $11 a barrel this week, a sign of how much more the seaborne benchmark is paying for its exposure to Gulf shipping risk than landlocked U.S. crude.
Crude flows through Hormuz, the narrow waterway that carries roughly a fifth of the world's oil, have largely recovered to prewar levels, but the recovery remains fragile: at least three tankers were reportedly attacked this week while transiting the strait, and insurers have responded by pushing up war-risk premiums and lengthening the voyages ships take to avoid the most exposed lanes.
Pricing Risk, Not Yet a Shortage
The U.S. Energy Information Administration has responded to the tension by lifting its price outlook. In its latest Short-Term Energy Outlook, the agency raised its forecast for average Brent prices in the fourth quarter of 2026 to roughly $104.69 a barrel, up from $90.66 projected just a month earlier — a $14-a-barrel upward revision in a single month. The agency ties the jump largely to the region, estimating that shut-in production in September was already at its lowest level since hostilities began, even as it expects convoys and alternate routes to lift exports further over the rest of the year.
That distinction matters for how long the premium holds: the extra price buyers are paying mostly reflects the probability of disruption, not a disruption that has actually materialized in the barrel count. EIA still expects the premium to fade over the medium term, projecting Brent easing to an average of roughly $84 a barrel in 2027. For now, though, sustained crude above $100 is feeding into other markets — bond traders have cited elevated energy costs as one reason longer-dated Treasury yields have climbed to multi-decade highs this month, and fuel-intensive industries from airlines to shipping are absorbing a cost headwind that was largely absent for most of the past two years.
With the naval buildup not due to finish until late November, traders have weeks more of headline risk to price before finding out whether the additional firepower proves to be deterrence, prelude to further strikes, or ultimately a non-event for the barrels actually moving through the Gulf.
