As military clashes and hostilities between Washington and Tehran escalate once more, and observable vessel traffic through the Strait of Hormuz—which accounts for 20-30% of global energy transport—has once again fallen to a severe standstill of zero throughput, Asian refiners are seeking to purchase more US crude.
The stalled passage of oil tankers through the Strait of Hormuz has driven Brent crude and West Texas Intermediate (WTI) crude to surge to around $85 and $80 per barrel respectively this week, prompting Asian refineries to renew inquiries for US spot crude.
During normal periods of transit through the Strait of Hormuz, approximately 90% of the crude oil and condensate exported via the waterway flows to Asia. The declining reliability of Middle Eastern supply is likely to force refineries in China, India, Japan, and South Korea to shift more towards sources in the United States, Brazil, and West Africa.
Consequently, the United States stands to gain from higher crude prices, increased export volumes, greater terminal utilization, and a strengthened position as the global marginal supplier, particularly benefiting producers with low-cost Permian Basin capacity and Gulf of Mexico export channels.
At least three executives involved in selling US crude and procuring crude for Asian oil and gas processors indicated that Asian refineries have once again begun negotiations for US crude spot cargoes. They requested anonymity as they were not authorized to speak publicly.
Previously, such discussions had fallen silent due to a flood of backed-up Middle Eastern crude and gas supplies entering the spot market. Now, with the US-Iran ceasefire agreement appearing virtually defunct, these crude flows are under threat again.
Attacks on vessels have increased in recent days, coinciding with Washington's re-imposition of a blockade on Iranian ports. US President Donald Trump has also proposed a 20% toll on cargoes transiting the Strait of Hormuz with US support, which at current oil prices equates to roughly $30 million per very large crude carrier (VLCC).
In contrast, fees charged by Iran for similar voyages during the early stages of the US-Iran geopolitical conflict were around $2 million.
The deteriorating situation is disrupting shipping and oil markets, which had only recently been busy recalibrating as energy flows from the Persian Gulf resumed.
As of Tuesday, observable vessel traffic through the Strait of Hormuz had almost completely halted, although Iran has been quietly moving crude oil tankers out of the Gulf while keeping their transponders turned off.
Key Beneficiaries Among Listed Companies
For listed companies, the upstream profit elasticity is most direct for Exxon Mobil, Chevron, and certain independent shale producers.
Exxon Mobil has already projected that its second-quarter profit could increase by up to approximately $5 billion compared to the first quarter, driven by higher oil prices and improved refining margins, with its upstream business contributing around $1.6 billion of that gain.
Another US oil and gas giant, Chevron, previously estimated that war-induced oil price increases could boost its quarterly upstream profit by $1.6 billion to $2.2 billion.
Beyond shale producers in the Permian region, US crude export terminals, pipeline and storage operators, and refineries exporting refined products overseas may also benefit as buyers in Asia and Europe reconfigure their supply chains.
The United States has emerged from this Middle Eastern geopolitical conflict as the world's largest oil exporter, commanding a significantly higher energy security premium than Gulf producers whose supplies must transit the Strait of Hormuz.
Potential Downsides and Risks
However, this is not a one-sided windfall without costs. Large integrated oil companies have exposure across upstream assets, refining, chemicals, and overseas production. While rising crude prices benefit oil production profits, they can also increase feedstock costs for refineries, compress demand for some chemicals, and raise expenses for transportation, insurance, and hedging losses.
US refineries, which had significantly ramped up exports to fill global refined product shortages, now face domestic gasoline inventories at seasonally low levels. Their profit红利 may be accompanied by rising US gasoline prices and political pressure.
Furthermore, if Strait transit resumes or diplomatic negotiations restart, the current geopolitical risk premium could rapidly unwind.
The geopolitical situation in the Middle East has deteriorated once again. The provisional ceasefire arrangement reached in June is unraveling due to ambiguous terms—the US demands unconditional, toll-free access through the Strait of Hormuz, while Iran insists on its right to manage the waterway temporarily and requires vessels to use its approved routes.
The US subsequently reinstated its blockade on Iranian shipping, revoked oil sales waivers, and conducted consecutive airstrikes. Iran has responded by attacking commercial vessels, US regional bases, and targets in Gulf states.
The current standoff has escalated from disputes over nuclear issues and sanctions to a direct contest for control of the Strait of Hormuz, rules for tanker passage, and the归属 of energy revenues. Although neither side has completely closed the technical window for negotiations, a cycle of military retaliation is overwhelming diplomatic processes, plunging Strait shipping and global oil prices back into a high-risk state.
