Sustained disruption to Middle East energy supplies is set to trigger a permanent shift in the global landscape, with analysts predicting a 20 per cent drop in global oil demand by 2050 as nations race toward energy independence.
A new conflict scenario released by Wood Mackenzie suggests that while a temporary US-Iran ceasefire has recently eased panic pricing, the long-term impact of supply fragility will halve global dependence on oil and gas imports over the next 25 years.
As countries prioritise national security over globally optimised supply chains, the energy mix is expected to rebalance decisively toward domestic resources.
While oil and gas demand face significant declines, nuclear generation is tipped to surge 40 per cent above base-case expectations by 2050, providing stable, fuel-secure baseload power.
“Geopolitical crises act as powerful catalysts for system change,” said Prakash Sharma, Wood Mackenzie’s Vice President of Scenarios & Technologies.
“In this scenario, the world moves decisively towards energy independence, with lasting implications for global fuel demand and trade.”
This transition comes with a security premium as domestic production and electrification prove more costly than the integrated global markets of the past. Furthermore, near-term emissions are expected to rise as nations delay coal plant retirements to fill immediate energy gaps.
The findings come as Rystad Energy revised its 2026 Brent price forecast down to US$87 per barrel following a two-week ceasefire agreement between the US and Iran. The deal, which potentially reopens the Strait of Hormuz in exchange for a halt to military strikes, has deflated the paper market, but physical supply remains perilously tight.
Rystad analysts warned that the toll booth environment, where Iran retains selective control over transit, means operational risks like high insurance premiums and tanker caution will persist.
This dislocation is hitting Asian refiners particularly hard; they remain caught between a rock and a hard place, unable to afford Atlantic Basin alternatives while Gulf supply lines remain effectively broken.
Even if the ceasefire holds, the recovery of the 11 million barrels per day currently shut-in across the Middle East will be a months-long process. Shipping logistics remain the primary bottleneck, with ballasting vessels unlikely to risk entering the Gulf until security is guaranteed.
“The initial recovery from major fields will be more than sufficient to meet the ramp-up of export volumes. Shipping logistics will remain the constraint on upstream recovery for several weeks,” said Fraser McKay, Head of Upstream Analysis at Wood Mackenzie.
“Thereafter, as those constraints begin to ease, the constraints on supply will shift to the upstream production, and this will expose the different challenges each country faces. More than half of most field’s previous supply levels could be restored before shipping constraints ease. Thereafter, different recovery profiles will emerge.”
In the gas market, the outlook is similarly slow. Qatar’s Ras Laffan LNG facility, a critical global supplier, may not return to full service until late August.
While some trapped cargoes may now exit the Strait, the structural damage to regional infrastructure and the time required to safely ramp up complex reservoirs mean the global energy crunch is far from over.
