Oil Prices Rise as Saudi Pipeline Outage and Houthi Attacks Deepen Supply Concerns

Oil prices moved higher on September 15 as fresh attacks on Saudi Arabia, the continued outage of the kingdom’s East-West Pipeline and falling vessel traffic through the Strait of Hormuz intensified fears about global crude supplies.

The latest developments have added another layer of risk to an already disrupted energy market. Brent crude briefly climbed above $108 a barrel, while U.S. West Texas Intermediate approached $104, as traders assessed whether damage to energy infrastructure and shipping routes could persist for weeks.

The central concern for the oil market is increasingly shifting from the immediate loss of supply to how long major export routes and infrastructure will remain disrupted. If the East-West Pipeline remains offline while shipping through Hormuz stays severely restricted, the pressure on available global crude supplies could become significantly larger.

Oil Prices Climb as Saudi Energy Risks Increase

Brent crude futures were up 21 cents, or 0.2%, at $105.89 a barrel by 1148 GMT on Tuesday after reaching an intraday high of $108.43. U.S. West Texas Intermediate futures gained 90 cents, or 0.89%, to $102.29 after touching $104.21 earlier in the session.

The price movement reflects growing concern that recent attacks could extend the disruption to Saudi energy infrastructure and transportation routes.

Saudi Arabia’s East-West Pipeline is particularly important because it provides an alternative route for moving crude toward the Red Sea when exports through the Strait of Hormuz are restricted.

Houthi Attacks Add to Saudi Oil Supply Concerns

The latest oil-market pressure followed new attacks claimed by Iran-backed Houthi forces in Yemen.

The Houthis said they launched dozens of missiles and drones toward a military air base in Khamis Mushait in southern Saudi Arabia. They said the attack targeted military infrastructure and was carried out in retaliation for Saudi airstrikes in Yemen.

The attacks followed an earlier strike that disrupted Saudi Arabia’s East-West Pipeline. Riyadh attributed that attack to Iranian-backed fighters operating in Iraq.

For oil traders, the combination is particularly concerning because it suggests that the risks to Saudi energy infrastructure are not isolated incidents. Continued attacks could make repairs, transportation and export planning more difficult.

Why the East-West Pipeline Matters to Global Oil Markets

The East-West Pipeline is strategically important because it gives Saudi Arabia a way to transport crude toward the Red Sea without relying entirely on the Strait of Hormuz.

That alternative becomes especially valuable when shipping through Hormuz is disrupted by military conflict or attacks on commercial vessels.

The latest outage therefore has consequences beyond Saudi Arabia. If the pipeline cannot return to operation quickly, Saudi Arabia could face increasing difficulty maintaining its normal export flows while other major routes are also under pressure.

Goldman Sachs estimated that the latest damage could threaten the remaining 2 million barrels per day of recent Yanbu exports, with repair estimates ranging from a very short interruption to as long as eight weeks.

The wide range of repair estimates demonstrates the uncertainty facing the market. A pipeline restored quickly would limit the supply impact, while a prolonged shutdown could dramatically change the oil-price outlook.

How a Prolonged Outage Could Affect Brent

Hamad Hussain of Capital Economics said that several weeks of East-West Pipeline disruption, without either lower demand or increased flows through Hormuz, could push Brent toward $130 a barrel.

That is not a guaranteed price target. It represents a scenario in which multiple supply disruptions continue simultaneously and the market cannot find enough alternative barrels to compensate.

This distinction is important because oil prices are determined by the balance between available supply and demand. A temporary infrastructure problem may cause a sharp but short-lived price spike, while a prolonged disruption can create a more persistent supply deficit.

Hormuz Traffic Falls Sharply

The Strait of Hormuz remains another major source of uncertainty.

Preliminary Kpler data showed commodity vessel traffic through the strait falling to just four vessels on Monday, compared with 10 the previous day.

Such a decline matters because Hormuz has historically been one of the world’s most important energy transportation corridors. Restrictions on shipping through the waterway can affect crude, refined products and other energy cargoes moving between Gulf producers and international markets.

Lower vessel traffic does not automatically equal an equivalent reduction in global oil supply, but it is a strong signal that shipping companies and traders remain concerned about security conditions.

Oil Tanker Attack Raises Additional Shipping Risk

Oman’s Maritime Security Centre said on Tuesday that the Panama-flagged oil tanker El Gaia was being towed toward an Omani port after an engine-room fire following an attack.

Another incident involving a commercial tanker adds to the wider uncertainty surrounding maritime transportation in the region.

For shipping companies, the problem is not limited to whether a vessel can technically pass through a particular route. Operators also have to consider crew safety, insurance, potential damage, delays and the possibility of repeated attacks.

As those risks increase, companies may choose to avoid certain routes or demand higher compensation for operating in dangerous areas. Those additional costs can eventually feed into freight rates and the delivered price of energy.

Saudi Arabia Could Face a Short-Term Export Squeeze

Buyers and traders cited in the market discussion warned that Saudi Arabia could exhaust crude available for export within days if the East-West Pipeline remains offline.

The reason is straightforward: Saudi Arabia needs functioning transportation infrastructure to move crude from production areas toward export terminals. If one major route is unavailable and another major route is heavily restricted, the country’s ability to deliver barrels to international buyers becomes constrained.

The pipeline strike was estimated to threaten up to 4% of global oil supply, highlighting why the market reacted strongly to the outage.

However, the ultimate impact will depend on how quickly Saudi Arabia repairs the infrastructure, how much crude can be redirected through alternative routes and whether shipping conditions through Hormuz improve.

Goldman Sachs Warns of Brent Above $120

Goldman Sachs said the recent attacks represented a meaningful escalation of the conflict and increased the probability that Brent could rise above $120 a barrel.

The bank’s scenario assumes that Gulf oil production could remain significantly below pre-war levels in 2027. Under such circumstances, the market would have to operate with a persistent reduction in supply.

A prolonged supply deficit would create a fundamentally different market environment from a short-term geopolitical price spike.

When traders expect an interruption to last only days, inventories and alternative shipments can cushion the impact. When the disruption is expected to last months, buyers begin competing more aggressively for available barrels, increasing the possibility of substantially higher prices.

Russia Adds Another Supply Problem

The global oil market is also facing pressure from Russia’s refining sector.

According to calculations based on information from fuel-market participants, half of Russia’s six largest diesel-producing refineries were forced to significantly reduce production or halt output during September following damage caused by drone attacks.

This development is especially important for refined fuel markets. Crude oil and refined products are connected, but disruptions at refineries can create shortages in products such as diesel even when crude production itself is not affected to the same degree.

A reduction in Russian refinery output therefore adds another layer of complexity to an already stressed energy market.

Why the Current Oil Shock Is Different

The current market is dealing with several risks at the same time rather than one isolated supply disruption.

There are concerns about Saudi infrastructure, shipping through Hormuz, attacks on commercial vessels, the Red Sea, Houthi activity and Russian refinery disruptions.

Each individual disruption may be manageable. The greater concern is the possibility that they reinforce one another.

What Could Push Oil Prices Toward $120 or $130?

Several conditions would need to persist for the more extreme oil-price scenarios to become increasingly plausible.

1. Prolonged East-West Pipeline Shutdown

The longer the pipeline remains offline, the greater the pressure on Saudi Arabia’s export logistics. An outage lasting several weeks would be much more significant than a short technical interruption.

2. Continued Low Hormuz Traffic

If commercial vessels continue avoiding the Strait of Hormuz, fewer barrels may reach international markets through the normal route.

3. More Attacks on Energy Infrastructure

Additional strikes against pipelines, terminals, refineries or storage facilities could quickly increase the market’s perception of supply risk.

4. Limited Alternative Supply

If other producers cannot quickly increase exports, the market would have fewer options to compensate for missing Gulf barrels.

5. Strong Demand

Higher prices are easier to sustain when oil consumption remains resilient. A significant slowdown in global economic activity, however, could reduce demand and limit the upside in crude prices.

What Could Prevent a Larger Oil Price Spike?

There are also factors that could prevent the most severe scenarios from materializing.

A rapid repair of the East-West Pipeline would restore an important transportation route. Improved security conditions could also allow shipping through Hormuz to recover.

At the same time, weaker economic growth could reduce global oil demand. Higher prices themselves can also eventually encourage consumers and businesses to reduce consumption, although that adjustment generally takes time.

The key question is therefore whether supply disruptions persist long enough to overwhelm the market’s ability to adapt.

Oil Prices Could Have Wider Economic Consequences

A sustained rise in crude prices would extend beyond energy companies and oil traders.

Higher crude prices can increase the cost of transportation, aviation, manufacturing and other energy-intensive activities. Refinery disruptions can also affect diesel and other fuel markets, creating additional pressure for businesses and consumers.

For central banks, the situation is particularly complicated. Higher energy prices can push inflation upward even when underlying economic demand is not especially strong.

If policymakers respond by keeping interest rates higher for longer, the oil shock could also affect borrowing costs, economic growth and financial markets.

What Investors Should Watch Next

• East-West Pipeline repairs: The timing of a restart will be one of the most important indicators for oil markets.
• Hormuz vessel traffic: A sustained recovery would reduce fears of a prolonged transportation disruption.
• Saudi export volumes: Actual shipments will reveal how severely the infrastructure problems are affecting supply.
• Houthi activity: Additional attacks could increase the risk premium in crude prices.
• Russian refinery output: Further disruptions could tighten diesel markets.
• Oil inventories: Inventory changes will show whether global markets are absorbing or struggling with the supply shock.
• Global demand: Economic weakness could partially offset the impact of supply disruptions.

Conclusion: Oil Market Faces a Critical Supply Test

Oil prices are rising because traders are increasingly concerned that the Middle East conflict could produce a prolonged disruption to both energy infrastructure and transportation routes.

The East-West Pipeline outage is particularly significant because it removes an important Saudi alternative to the Strait of Hormuz at a time when vessel traffic through the strait has already fallen sharply.

Fresh Houthi attacks, the reported tanker incident near Oman and reduced Russian refinery output add further uncertainty. Together, these developments have increased the possibility of a sustained supply squeeze rather than a short-lived geopolitical price spike.

Brent reaching the $120–$130 range is still a scenario rather than a certainty. The decisive factors will be the duration of the Saudi pipeline outage, the restoration of shipping through Hormuz, the frequency of further attacks and the availability of alternative global supplies.

For now, the oil market is focused less on one day’s price movement and more on a critical question: how long can the global energy system operate under simultaneous pressure on pipelines, shipping routes and refining capacity?
