Oil prices rise near $98 as US-Iran tensions threaten oil shipments through the Strait of Hormuz

Oil Prices Near $98 as U.S.-Iran Attacks Raise Strait of Hormuz Supply Fears

Oil prices climbed further on Monday as renewed U.S.-Iran attacks involving vessels around the Strait of Hormuz increased fears of prolonged disruptions to Middle East crude supplies.

Brent crude futures rose to around $97.48 a barrel, while U.S. West Texas Intermediate (WTI) crude reached about $92.62 a barrel during Monday trading, according to Reuters. Brent had already gained 7.8% last week, while WTI rose nearly 10% as renewed hostilities affected oil flows through the region.

The latest escalation is putting the Strait of Hormuz back at the center of global energy-market concerns. The waterway is one of the world's most important routes for oil transportation, meaning any prolonged disruption could have consequences for fuel prices, inflation and businesses worldwide.

Why Oil Prices Are Rising

The main concern for energy traders is the possibility that military tensions could further restrict commercial shipping through the Strait of Hormuz.

U.S. forces struck three Iranian oil tankers on Saturday, according to U.S. Central Command. Iran's Islamic Revolutionary Guard Corps Navy has also reported attacks involving tankers and U.S. vessels in the region.

The developments have increased uncertainty for shipping companies and oil traders. Even when physical oil supplies have not been completely halted, the risk of disruption can push crude prices higher as markets price in the possibility of tighter future supplies.

The main concern for energy traders is the possibility that U.S.-Iran tensions could further restrict commercial shipping through the Strait of Hormuz.

Reuters reported Monday that tanker traffic through the Strait had fallen significantly, adding to concerns about the availability of crude shipments from the Middle East.

That risk premium has helped push Brent crude close to the psychologically important $100-a-barrel level.

Brent Crude Moves Toward $100

Brent crude is now trading at levels not seen for several weeks.

Reuters reported that Brent rose as high as about $97.60 a barrel, its highest level in seven weeks, while WTI also moved higher.

The move follows a particularly strong week for oil markets. Brent gained 7.8% last week and WTI increased by almost 10% as U.S.-Iran hostilities resumed and concerns about oil flows through Hormuz intensified.

For investors, the question is no longer simply whether oil prices can reach $100. The bigger question is whether crude can remain near or above that level if shipping disruptions continue.

If the situation around Hormuz deteriorates further, prices could remain under significant upward pressure.

On the other hand, a reduction in military tensions or a recovery in commercial shipping could cause some of the recent gains to reverse.

Iran Plans New Restricted Maritime Zone

Another development adding uncertainty to the oil market is Iran's plan to establish a new restricted zone in the Gulf.

Iran said Monday that it plans to announce the new zone and publish maps for a proposed shipping corridor through the Strait of Hormuz in the coming days. Tehran said vessels entering the restricted area could face sanctions.

The proposed arrangement is expected to be connected to negotiations over the management of shipping through the strategic waterway.

For oil markets, the announcement is significant because it could create additional uncertainty for commercial vessels operating in the region.

Shipping companies must consider not only the cost of transporting oil but also the potential security risks involved in passing through the area.

That uncertainty can translate into higher transportation and insurance costs, potentially adding to the price pressure already coming from crude markets.

What the Strait of Hormuz Means for Global Oil

The Strait of Hormuz is one of the world's most important energy chokepoints.

A significant portion of global oil shipments has historically passed through the waterway. As a result, any prolonged disruption can have consequences far beyond the Middle East.

When tankers are delayed or forced to avoid the route, the available supply of crude can become tighter in other markets.

That can push international benchmark prices higher and increase costs for refiners.

The impact eventually reaches consumers through gasoline, diesel, jet fuel and other petroleum products.

The current situation is therefore being closely watched by governments, energy companies, airlines, transportation businesses and investors.

U.S. Gas Prices Are Already at Record Labor Day Levels

American consumers are already dealing with unusually high fuel prices.

According to the Associated Press, the national average price for regular gasoline reached $4.14 per gallon for Labor Day 2026. That was nearly $1 higher than the same period last year and above the previous Labor Day record of $3.82 set in 2012.

Diesel prices also reached a national average record of approximately $5.85 per gallon, increasing costs for trucking and other transportation businesses.

Higher gasoline prices can directly affect household budgets, particularly for Americans who drive long distances for work or travel.

The effects can also spread through the wider economy because transportation is an important part of the cost of moving food, consumer goods and industrial products.

Inflation Risk Is Back in Focus

The increase in oil prices is also attracting attention from economists and financial markets because energy costs can influence inflation.

When gasoline and diesel become more expensive, households have less money available for other purchases.

Businesses can also face higher transportation and operating costs. Some companies may absorb those costs, while others may eventually pass part of the increase to customers.

Reuters reported Monday that investors were increasingly focused on inflation risks as crude prices climbed and geopolitical tensions remained elevated.

That makes upcoming U.S. economic data particularly important.

Investors will be watching inflation indicators and other economic releases for signs of whether higher energy costs are beginning to affect broader price trends.

What It Means for U.S. Businesses

Higher oil prices can have mixed effects on American businesses.

Energy producers can benefit when crude prices rise because stronger prices can improve revenue and profitability.

However, companies that rely heavily on fuel can face the opposite situation.

Airlines, trucking companies, shipping firms and manufacturers may see operating costs increase if fuel prices remain elevated.

Retailers can also face higher transportation expenses as products move through supply chains.

For smaller businesses with limited pricing power, sustained increases in fuel costs can be particularly challenging.

This is why oil prices are closely watched even by companies that have nothing to do directly with the energy industry.

Markets Watch the Next Move

Global financial markets are also monitoring the oil-price surge.

Reuters reported Monday that stock markets were under pressure as investors considered the combination of higher oil prices, geopolitical uncertainty and inflation risks. U.S. markets were operating with lighter activity because of the Labor Day holiday.

Energy stocks can benefit from higher crude prices, but other sectors may face pressure if expensive fuel reduces consumer spending or increases business costs.

The longer oil remains elevated, the more important its effect on corporate earnings and inflation expectations could become.

For investors, developments around the Strait of Hormuz are therefore likely to remain an important market-moving factor.

OPEC+ Production Policy

Oil traders are also watching the response from major oil-producing countries.

OPEC+ has maintained its existing production policy for October, according to Reuters reporting.

The decision means the market remains particularly sensitive to developments affecting actual oil shipments.

If Middle Eastern supply disruptions become more severe, additional production from other producers could become important in limiting the impact.

But if shipping disruptions remain temporary and commercial traffic recovers, the market could eventually see some relief.

What Happens Next?

The direction of oil prices will largely depend on developments over the coming days.

Traders will closely monitor:

  • Commercial tanker traffic through the Strait of Hormuz
  • Further U.S.-Iran military action
  • Iran's planned restricted maritime zone
  • Middle East crude exports
  • U.S. gasoline and diesel prices
  • Upcoming U.S. inflation data
  • OPEC+ production decisions
  • Global demand for crude oil

A further escalation could push Brent toward or above the $100-a-barrel threshold.

However, if tensions ease and shipping through Hormuz improves, some of the recent oil-price gains could disappear.

The key issue for markets is therefore not just the current price of crude, but how long the supply risk remains elevated.

Bottom Line

Oil prices moved higher again on September 7, 2026, as renewed U.S.-Iran attacks involving vessels around the Strait of Hormuz increased concerns about prolonged disruptions to Middle East oil supplies.

Brent crude climbed toward $98 a barrel, while WTI traded above $92. Brent had already gained 7.8% during the previous week.

The rise comes as American consumers are already facing record Labor Day gasoline and diesel prices.

The next major test for the oil market will be whether shipping through the Strait of Hormuz continues to deteriorate or begins to recover.

If disruptions continue, oil prices could remain elevated and create additional inflation pressure for the U.S. economy. If tensions ease and tanker traffic returns to normal, crude prices could move lower.

For now, the Strait of Hormuz remains one of the most important factors to watch in global energy markets.
