Oil Prices Rise as Supply Risks Intensify
Oil prices advanced on Wednesday after the International Energy Agency reduced its forecast for global oil supply and renewed attacks on vessels intensified concerns about Middle Eastern exports.
Brent crude rose approximately $0.90 to $89.81 per barrel, while US West Texas Intermediate gained around $0.88 to $84.08.
The gains extended a period of elevated volatility as traders assessed whether negotiations could restore shipping through the Strait of Hormuz and reduce the geopolitical risk premium embedded in crude prices.
However, a substantial increase in US crude inventories provided a counterweight to the supply concerns.
The oil market is being pulled between severe disruption to strategic shipping routes and evidence that US crude inventories may be increasing.
IEA Forecasts a Larger Supply Contraction
The IEA expects global oil production to decline by approximately 4.3 million barrels per day in 2026, equivalent to around 4%.
That represents a larger contraction than the 3.7-million-barrel-per-day decline estimated in its previous monthly report.
The agency now forecasts total global supply of approximately 102.02 million barrels per day in 2026, its lowest projection for the year.
The revision reflects the continuing effect of the Middle East conflict on:
- Oilfield production.
- Export terminals.
- Tanker availability.
- Shipping insurance.
- Storage capacity.
- Regional supply chains.
- Transport through major waterways.
The forecast remains sensitive to geopolitical developments. A sustained reopening of the affected shipping routes could allow some production and exports to recover, while further military escalation could produce additional downward revisions.
Hormuz Traffic Remains Severely Restricted
The Strait of Hormuz is one of the most important maritime passages in the global energy market.
Before the recent disruption, approximately one-fifth of global oil and liquefied-natural-gas supplies normally passed through the waterway.
Latest shipping data showed that vessel traffic through Hormuz and Bab el-Mandeb had fallen to approximately eight transits, compared with around 125–140 per day before the conflict.
Restricted traffic can affect the oil market even when production facilities remain operational. Producers may be forced to reduce output if they cannot export crude or obtain enough storage capacity.
The disruption can also increase:
- Tanker chartering costs.
- Maritime insurance premiums.
- Delivery times.
- Security expenses.
- Demand for alternative shipping routes.
- Price differences between regional crude grades.
- Refinery procurement costs.
Renewed Vessel Attacks Increase Market Tension
Reports of new attacks on vessels in the Strait of Hormuz and Bab el-Mandeb reinforced concerns that normal shipping conditions would not return quickly.
Iran has indicated that Hormuz will remain restricted unless the United States accepts its conditions for ending the conflict, including demands connected to frozen assets.
The increasingly complicated diplomatic positions have reduced expectations of an immediate agreement.
Oil prices may therefore remain highly sensitive to:
- Announcements from Iran and the United States.
- Negotiations facilitated by Oman.
- New attacks on commercial vessels.
- Changes in naval protection.
- Statements regarding sanctions or frozen assets.
- Evidence that shipping traffic is recovering.
- Decisions by Gulf producers to restore or reduce production.
Bab el-Mandeb Adds Another Supply-Chain Risk
The Bab el-Mandeb Strait connects the Red Sea with the Gulf of Aden and provides an important route toward the Suez Canal.
Restrictions in this area can force ships to travel around the Cape of Good Hope, increasing journey times, fuel consumption and transportation costs.
Simultaneous disruption to Hormuz and Bab el-Mandeb creates a broader risk for energy flows because both routes are important to trade between the Middle East, Europe and Asia.
- Delayed oil and refined-product deliveries.
- Higher freight rates.
- Increased demand for tankers.
- Reduced effective shipping capacity.
- Greater regional price differences.
- Pressure on refinery inventories.
- Higher costs for European and Asian energy importers.
US Inventories Provide a Bearish Counterweight
While geopolitical developments supported oil prices, preliminary US inventory data pointed to a significant increase in crude stocks.
The American Petroleum Institute reportedly estimated that US crude inventories rose by approximately 9.1 million barrels during the latest reporting week.
If confirmed by the Energy Information Administration, the increase could indicate that near-term US supply is more comfortable than international market conditions suggest.
Traders will also examine:
- Gasoline inventories.
- Distillate stocks.
- Refinery utilisation.
- Domestic oil production.
- Crude imports and exports.
- Inventories at the Cushing delivery hub.
- Implied fuel demand.
- Strategic Petroleum Reserve movements.
The preliminary report indicated that gasoline and distillate inventories declined, potentially suggesting that end-user fuel consumption remained resilient.
Supply Disruption May Persist Into 2027
The US Energy Information Administration expects some Middle Eastern production to remain unavailable through the end of 2027.
Approximately 5.5 million barrels per day of output—more than 5% of global consumption—was disrupted in July, according to the agency’s estimates.
The EIA estimates that around 600,000 barrels per day of regional output could remain offline through 2027.
The agency forecasts average 2026 prices of approximately:
- $86.81 per barrel for Brent crude.
- $80.88 per barrel for WTI crude.
These are annual forecasts rather than fixed price targets. Actual prices may move substantially above or below them as geopolitical conditions change.
Higher Oil Prices Could Affect Inflation
A sustained rise in oil prices could create additional inflation pressure across the global economy.
The direct effect is usually visible in petrol, diesel and household energy costs. Indirect effects can appear through transportation, manufacturing and supply chains.
Industries that may face higher costs include:
- Airlines.
- Logistics companies.
- Shipping operators.
- Chemicals manufacturers.
- Plastics producers.
- Agricultural businesses.
- Construction companies.
- Consumer-goods manufacturers.
- Electricity generators.
A brief geopolitical spike may have limited long-term consequences. A sustained period near or above $90 per barrel could have a more noticeable effect on inflation expectations and corporate margins.
Federal Reserve Outlook Becomes More Complicated
The oil rally arrived as investors prepared for the latest US Consumer Price Index report.
July inflation data may not fully reflect the most recent energy-price increase because changes in crude markets take time to reach retail fuel prices and broader inflation measures.
Nevertheless, continued oil-market disruption could influence future Federal Reserve decisions.
- Weaker employment data may support easier monetary policy.
- Persistent inflation could justify keeping rates restrictive.
- Higher energy prices may raise future inflation expectations.
- Geopolitical uncertainty could weaken economic activity.
- Rising transportation costs may affect corporate earnings.
- Higher bond yields could tighten financial conditions.
Oil Strength Could Affect Other Markets
USDCAD
Canada is a major energy exporter, so stronger crude prices can sometimes support the Canadian dollar. However, US interest rates, domestic Canadian data and broader risk sentiment may outweigh the effect of oil.
Gold
Gold may benefit from geopolitical uncertainty and demand for defensive assets. At the same time, higher oil-driven inflation could lift Treasury yields and the US dollar, creating competing pressure on the metal.
Equity markets
Energy producers may benefit from higher realised oil prices, while fuel-intensive businesses could experience margin pressure.
Asian markets
Several Asian economies are major net energy importers. Higher crude prices can increase import costs, weaken trade balances and create additional inflation pressure.
What Traders Should Monitor Next
- IEA supply-forecast revisions.
- Official US crude-inventory data.
- Shipping traffic through Hormuz.
- Vessel movements through Bab el-Mandeb.
- US-Iran negotiations.
- Reports of attacks on energy infrastructure.
- Gulf production and export levels.
- Strategic-reserve announcements.
- OPEC+ production decisions.
- US shale-oil output.
- Refinery activity and fuel demand.
- Brent’s reaction around $90.
- WTI’s performance near $84.
- US inflation figures.
- Treasury-yield movements.
- Changes in the US dollar.
Because geopolitical headlines can appear outside regular market hours, oil prices may gap sharply when trading resumes.
Market Outlook
The IEA’s downward revision reinforces the view that the disruption to global oil supply is more persistent than previously expected.
Restricted shipping through the Strait of Hormuz and Bab el-Mandeb, combined with renewed vessel attacks, may continue supporting a geopolitical premium in Brent and WTI.
Brent’s approach toward $90 places the market near an important psychological level. A sustained move above this area could strengthen upward momentum, particularly if shipping conditions deteriorate or official inventory data indicate tighter supply.
However, a large confirmed increase in US crude inventories or meaningful progress toward reopening Hormuz could limit further gains.
The near-term outlook therefore remains headline-driven. Supply risks currently support oil prices, but changing diplomatic expectations and inventory data could produce rapid reversals.
