Oil set to surge ~9% as Iran strikes close Strait of Hormuz

Market snapshot

US crude futures are set to open roughly 9% higher, moving from about $67 per barrel to above $73 per barrel when trading resumes. That level would be the highest since June 2025. Brent and other global benchmarks are positioned for significant gains as Middle East tensions escalate. Key market tickers referenced where relevant: US crude (US), broker markets (IG), regional risk adviser (RM), ports operator (DP), fuel-price monitor (AA), UK share index (FTSE), UK market indicator (UK).

Immediate price drivers

• Military strikes linked to the US–Israel–Iran conflict and an effective closure of the Strait of Hormuz have tightened short-term supply expectations and raised price premia for physical crude.
• Maritime disruption: at least 150 tankers carrying crude, liquefied natural gas and oil products dropped anchor in open waters across the Gulf region, constraining immediate shipments and increasing near-term backwardation risk.
• A tanker in the Strait of Hormuz was attacked and an oil tanker sustained damage that injured four crew, elevating operational risk and war-premia for vessels transiting the route.
• About one fifth (≈20%) of global oil consumption transits the Strait of Hormuz; a sustained closure would materially disrupt shipments from Saudi Arabia, the UAE, Iraq, Kuwait and Iran and create acute supply-tightness.

Supply-side actions and limitations

• Opec+ has agreed in principle to raise output by 206,000 barrels per day in April, up from earlier expectations of a 137,000 b/d increase. That incremental 206,000 b/d rise is limited relative to volumes at risk if the strait remains closed or shipping is widely curtailed.
• Analysts’ scenario ranges embedded in current market pricing: a material supply disruption could push oil toward $80 per barrel, while a severe escalation reopens the possibility of $100-plus oil in extreme risk-off scenarios.

Shipping, ports and insurance

• Major regional port operations have been suspended or limited; at least one major hub suspended operations and several carriers temporarily stopped bookings into the Gulf region, delaying cargo uptake.
• War-risk concerns are prompting underwriters and marine insurers to re-price hull and war-risk cover, raising transport costs and freight premiums. Higher insurance and rerouting costs amplify the effective supply squeeze even where physical production is unchanged.
• Freight-rate volatility and time-to-market variability should be monitored as part of delivery-cost estimation for refiners and trading desks.

Market spillovers and demand-side effects

• Wholesale crude gains are likely to filter through to retail fuel: current UK pump prices stand near 132.9p per litre for petrol and 142.4p per litre for diesel. Upward pressure is likely if crude remains elevated and a scheduled 5p-a-litre fuel-duty reversal proceeds.
• Investors are rotating into traditional safe havens; gold and silver posted multi-week gains across weekend broker markets (IG).
• Energy-sensitive equity indices are pricing in risk: the FTSE 100 is expected to open lower after a recent record, Gulf regional markets saw widespread declines and one market suspended trading for exceptional circumstances. A major national oil company’s shares rose, reflecting anticipated higher hydrocarbon earnings.

Trading and risk-management implications for professionals

• Short-term traders: volatility is elevated. Use tighter stop management, monitor shipping-lane advisories and insurance-rate notices, and watch for confirmation from futures liquidity when US hours reopen.
• Physical market participants and logistics teams: expect disrupted loadings, higher freight and war-risk premia, selective port closures and delays. Contingency planning for rerouting, alternative loading ports and storage access is prudent.
• Institutional investors and risk officers: perform scenario-based stress tests on energy price exposures and inflation-sensitive holdings. Assess macro pass-through to fuel, transport and industrial input costs, and model potential central bank reactions to commodity-driven inflation.

Actionable data points (quick reference)

• Projected near-term US crude gap: ~+9% (from ~$67/b to >$73/b).
• Opec+ agreed incremental output for April: +206,000 barrels per day (previously expected +137,000 b/d).
• Tankers anchored in Gulf region: at least 150.
• Crew injuries reported: 4.
• Share of global oil transiting Strait of Hormuz: ~20%.
• UK pump prices: petrol ~132.9p/l, diesel ~142.4p/l; scheduled fuel-duty reversal: 5p/l.

What to watch next (priority signals)

• Reopening or continued closure of the Strait of Hormuz and any further maritime incidents affecting tankers.
• Implementation and scale of Opec+ output adjustments beyond the agreed 206,000 b/d increment.
• Shipping insurance rate announcements and carrier routing changes that will affect time-to-market and delivered costs.
• Benchmark futures movements during US market hours: confirmation of the projected ~9% gap higher and whether prices sustain above $73 per barrel.

Bottom line

The convergence of Iran-linked strikes, an effective disruption of the Strait of Hormuz and constrained Opec+ supply responses has created a high-probability scenario for a sharp near-term rise in crude prices. Market participants should prepare for elevated volatility, increased shipping and insurance costs, and a clear risk of pump-price inflation if disruptions persist. Traders, physical operators and institutional investors should prioritize contingency logistics, tighter risk controls and scenario-run stress testing of energy exposures.
