Oil Prices Surge as Iran Reviews Hormuz Bill Targeting U.S. and Israeli Vessels
Oil prices climbed sharply as renewed uncertainty surrounding the Strait of Hormuz pushed geopolitical risk back to the center of global energy markets. Brent crude rose more than $3 a barrel on Thursday after reports emerged that Iranian lawmakers were reviewing legislation that could prohibit U.S. and Israeli vessels from passing through one of the world’s most important energy corridors.
Brent crude futures settled $3.04 higher, or 3.83%, at $82.49 a barrel, while U.S. West Texas Intermediate crude gained $2.07, or 2.75%, to settle at $77.29. The size of the move showed how quickly oil traders remain prepared to add a geopolitical premium when developments threaten shipping through Hormuz.
The pressure did not disappear with Thursday’s close. On Friday, Brent advanced again to $83.55 a barrel, while WTI finished at $78.18, as uncertainty continued over the terms under which shipping might resume more freely through the strategic waterway.
For global energy markets, the issue now extends beyond whether ships can physically move through the strait. We are watching a much broader confrontation over who controls passage, which vessels receive access, whether shipping fees will be imposed and how any new system would operate under continuing tensions between Iran and the United States.
Iran’s Hormuz Bill Raises the Stakes for Global Shipping
The proposed Iranian legislation has immediately drawn attention because of the restrictions it could place on vessels linked to Tehran’s principal adversaries.
The plan remains under review rather than enacted into law. According to details reported from Iran, the proposal could prevent vessels belonging to the United States and Israel from passing through the Strait of Hormuz and could impose significant penalties on ships that violate the restrictions.
The preliminary language reportedly goes further than simply targeting nationally flagged vessels. It could also affect certain cargoes connected to Israel and potentially ships associated with countries or organizations Iran considers hostile.
Violations could carry exceptionally heavy consequences. The reported draft includes potential fines reaching 20% of a vessel’s cargo value, a provision that could dramatically increase the financial risk associated with attempting passage without Iranian approval.
That possibility helps explain the oil market’s immediate reaction. Traders are not simply calculating how many American or Israeli ships normally travel through Hormuz. They are trying to determine whether the legislation signals a broader Iranian effort to formalize control over maritime traffic.
Why the Strait of Hormuz Matters So Much to Oil Prices
Few waterways can influence energy prices as rapidly as the Strait of Hormuz.
The narrow maritime passage connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. Major oil producers, including Saudi Arabia, Iraq, Kuwait, the United Arab Emirates, and Qatar, depend heavily on routes through the region to reach international customers.
Before the current disruption, approximately 20 million barrels of oil per day regularly moved through Hormuz. U.S. Energy Information Administration data show that flows averaged 20.9 million barrels per day during the first half of 2025, roughly equivalent to 20% of global petroleum liquids consumption.
The route is equally important for natural gas.
Around 20% of global liquefied natural gas trade passed through Hormuz in 2024, according to the EIA. Qatar accounted for the largest share, with much of that LNG destined for Asian economies including China, India and South Korea.
That concentration means even the possibility of additional restrictions can move prices.
Markets do not need to see a complete shutdown before reacting. Higher insurance premiums, delayed tanker movements, uncertainty over permissions or fears of military escalation can all increase transportation costs and tighten the amount of readily available crude.
Alternative Oil Routes Cannot Fully Replace Hormuz
One reason Hormuz remains so powerful is that there are limited alternatives capable of replacing its enormous shipping capacity.
Saudi Arabia and the United Arab Emirates operate pipelines that allow some crude to bypass the strait. However, the EIA estimates that the major available Saudi and UAE pipelines together provide roughly 4.7 million barrels per day of bypass capacity.
That figure represents only a fraction of the oil historically transported through Hormuz.
As a result, producers cannot simply redirect every tanker cargo through pipelines if conditions deteriorate. Any prolonged reduction in maritime traffic can eventually force buyers to draw more heavily on inventories, search for alternative suppliers or pay higher prices for immediately available barrels elsewhere.
This imbalance between normal Hormuz flows and practical bypass capacity explains why political developments in Tehran can reverberate through oil markets thousands of miles away.
Iran and Oman Negotiations Add Another Layer of Uncertainty
The proposed Iranian legislation comes as Iran and Oman continue discussions about new arrangements governing passage through the strait.
Those negotiations could become one of the most important elements determining the direction of oil prices in the coming weeks.
Reports on the emerging framework indicate that Iran could gain an expanded role in managing inbound shipping routes while Oman remains central to outbound navigation. Tehran has also pushed for payments associated with commercial traffic, although the precise structure and size of any charges remain disputed.
Washington has resisted the idea that Iran should effectively collect compulsory tolls or gain unrestricted authority over international shipping.
That disagreement creates a difficult negotiating problem.
A deal that restores substantial tanker traffic could reduce immediate supply concerns and pressure oil prices lower. A system that leaves major restrictions, expensive fees or political exclusions in place could maintain a significant geopolitical premium.
We therefore see the details of any agreement becoming almost as important as the announcement of an agreement itself.
Markets Are Pricing the Risk of a New Hormuz System
The latest oil rally shows how dramatically the meaning of “reopening Hormuz” has changed.
For traders, reopening no longer necessarily means returning to the conditions that existed before the regional conflict. Instead, discussions increasingly revolve around a new framework involving navigation corridors, Iranian authority, Omani involvement, possible service charges and restrictions on specific countries. That distinction matters.
An open waterway operating under disputed political conditions could remain vulnerable to sudden disruptions. Tanker owners must consider insurance requirements. Buyers must evaluate delivery risks. Governments must determine whether vessels connected to their countries could legally or safely use the new routes.
Those uncertainties can keep oil prices elevated even when substantial volumes continue moving.
The result is a market that can swing sharply with every diplomatic announcement, military development or change in proposed shipping rules.
Regional Tensions Keep the Oil Risk Premium Alive
Hormuz is not the only source of concern. Developments elsewhere in the Middle East have reinforced fears that disruption could spread across several strategically important transportation corridors. Reports of renewed Houthi military activity have kept attention on shipping risks around Yemen and the Bab el Mandeb Strait, another key route connecting the Red Sea with the Gulf of Aden.
That creates the possibility of overlapping pressure on global maritime trade. If disruptions simultaneously affect Hormuz and Red Sea routes, energy companies could face longer voyages, more expensive insurance and complicated supply chains.
Oil traders therefore remain highly sensitive to signals that regional fighting could expand rather than ease.
The market is also balancing geopolitical risks against expectations about global demand and available supply. That tension can produce dramatic reversals. Positive diplomatic headlines can send crude lower, while reports suggesting tighter restrictions can quickly reverse those losses. Thursday’s rally provided a clear example of that volatility.
Asian Energy Importers Face Particularly High Exposure
The consequences of Hormuz restrictions extend well beyond the Middle East and the United States.
Asia receives a large share of the oil and LNG transported through the strait. Major economies depend on Persian Gulf producers to supply refineries, power stations, and industrial facilities.
The LNG market demonstrates that exposure clearly. The EIA reported that 83% of LNG moving through Hormuz in 2024 was headed from Persian Gulf exporters toward Asian markets.
For large importers, prolonged disruption can create more than higher crude prices.
Refiners may compete more aggressively for barrels originating outside the Gulf. LNG buyers may face increased competition for alternative cargoes. Shipping expenses can rise, while governments may feel greater pressure to protect strategic inventories.
Those secondary effects are one reason developments involving Hormuz can influence inflation expectations and economic policy far beyond the immediate conflict zone.
Oil Prices Could Remain Volatile as Hormuz Talks Continue
The next major market move will likely depend on whether negotiations produce a workable shipping arrangement or generate another confrontation over control of the strait.
A credible agreement that significantly restores commercial traffic could remove some of the geopolitical premium currently embedded in crude prices. Greater tanker movement would also improve confidence that Gulf producers can deliver supplies without repeated interruptions. The opposite scenario carries considerably more risk.
If Iranian lawmakers advance legislation restricting U.S. and Israeli vessels, if Tehran insists on terms Washington rejects, or if negotiations with Oman stall, markets could begin pricing a longer period of constrained shipping.
Recent data already show how much conditions have changed. EIA estimates indicate oil flows through Hormuz averaged about 14.6 million barrels per day in the first quarter of 2026, significantly below levels recorded during 2025.
The reduction illustrates why traders remain cautious even when vessels continue to transit the region.
Hormuz Has Become the Market’s Critical Geopolitical Trigger
The latest rise in crude prices is ultimately about more than one parliamentary proposal. It reflects a deeper transformation in the way global energy markets view the Strait of Hormuz. What was once treated primarily as a strategic chokepoint is increasingly becoming the center of a political struggle over access, authority, shipping costs and regional influence.
Iran’s proposed restrictions on U.S. and Israeli vessels have intensified that uncertainty at a moment when Tehran and Oman are simultaneously discussing a new maritime arrangement. For oil markets, every detail now carries weight.
Brent’s $3.04 jump on Thursday demonstrated how quickly traders can react when the possibility of tighter Hormuz restrictions returns to the headlines. Its additional rise on Friday showed that the concern was not merely a one-session response.
Until the rules governing the strait become clearer, the world’s most important energy passage will remain a powerful source of volatility. A breakthrough could release some pressure from crude prices, but another breakdown in diplomacy could place the Strait of Hormuz, and the enormous volume of energy tied to it, back at the center of the global oil market.
