Iran war: How high could oil and gas prices go?
Mar 3rd 2026
Oil and gas outcomes range from a modest premium if fighting stays local to severe global price shocks if Gulf exports or key shipping routes are disrupted, with spare capacity, policy responses and demand changes determining how high prices go.
- Limited escalation would add a modest risk premium, lifting Brent by about $5 to $20 a barrel in the short term.
- If tankers are hit or the Strait of Hormuz sees intermittent closures, Brent could spike into the $150 to $200 range within weeks.
- A prolonged shutdown of Gulf exports could push Brent above $200 a barrel and trigger large gas price shocks in Europe and Asia.
- Saudi and UAE spare capacity and a sustained U.S. shale response can cap spikes over months by replacing some lost barrels.
- Releases from strategic petroleum reserves and coordinated policy moves can blunt immediate peaks but cannot fully offset long term supply losses.
- Demand destruction, economic slowdown and higher shipping and insurance costs are the main constraints on runaway prices.
