Oil markets initially treated the Iran war as a brief bullish disruption in a long-term bearish trend. But traders are now betting that oil prices will remain elevated through 2028, forcing a rethink of the global inflation outlook.
Eight months into the war, the buffers that helped absorb the initial energy shock – most notably onshore crude oil stockpiles – are wearing dangerously thin. At the same time, the recovery in crude exports through the Strait of Hormuz remains fragile, global refining capacity has been eroded and credible diplomatic pathways to end the conflict appear narrower than ever.
Global benchmark Brent crude futures tell the story. Contracts for delivery in December 2027 have climbed more than 13 per cent since the start of September to $86 a barrel, the highest level for the contract, while December 2026 contracts have gained around 12pc.
The Brent forward curve is not a price forecast, of course. But it reflects the willingness of refiners, airlines, commodity traders and asset managers to lock in elevated prices months and even years into the future. In effect, market participants are paying a premium against the possibility that today’s disruptions will become tomorrow’s normal.
This market positioning stands in stark contrast to widely held industry expectations of a recovery in global oil supplies next year. The International Energy Agency projects global supply will rise to 108.3 million barrels per day (bpd) in 2027 from 100.7m bpd this year as Middle Eastern exports recover.
Demand, meanwhile, is forecast to increase from 102.4m bpd to 104.4m bpd next year, still slightly below 2025 consumption. This recovery is expected to be concentrated in petrochemical feedstocks rather than transportation fuels like diesel.
Regardless, the agency’s projected balances imply a sizeable supply surplus next year that would normally weigh on prices. Yet the steady rise in long-dated futures suggests investors are increasingly sceptical that this recovery will fully materialise or, if it does, that it will endure.
The standoff between Washington and Tehran remains centred on control of the Strait of Hormuz. While oil flows through the strategic waterway have rebounded to near pre-war levels in recent weeks thanks partly to US naval support, Iran has intensified attacks on vessels in the past week and threatened further disruption.
The conflict has also expanded beyond the Gulf. Yemen’s Iran-aligned Houthis have recently stepped up missile and drone attacks on Saudi Arabia, including strikes this week on the headquarters of Saudi Arabia’s state-owned oil giant Aramco in Dhahran.
Given this backdrop, every barrel leaving the Gulf now carries a widening security premium. Complex logistics, elevated freight rates, high insurance costs and military protection now account for nearly a third of the cost of moving a barrel of oil out of the region, compared with 3pc before the war.
Absent a durable settlement over Hormuz, much of that cost is likely to remain entrenched in prices for the foreseeable future.
The strain is even more visible in diesel markets. Benchmark European diesel futures hit a record $1,480 per metric tonne, equivalent to around $210 per barrel, in mid-September amid an acute shortage of supplies caused by disruptions in the Middle East and Russia.
