Brent crude tracks toward $100 as the U.S.-Iran Strait of Hormuz deal collapses, leaving crude tanker flows near zero and 11 mb/d of Gulf output offline.
- Brent crude surged roughly 5% to $87.72 on August 10 and is tracking toward $100 as the Iran-U.S. Hormuz deal unravels.
- Crude tanker traffic through the Strait has fallen to near zero, with more than 11 million barrels per day of Gulf output still offline.
- Saudi Arabia's East-West Pipeline has lost ~700,000 bpd of throughput; global inventories are heading to their lowest since at least 2003.

Brent crude surged approximately 5% to settle at $87.72 a barrel on August 10 and extended its advance into the following session, tracking toward the $100 threshold, as evidence mounted that the June peace framework for the Strait of Hormuz has irreversibly broken down. With crude tanker traffic through the world's most critical oil chokepoint reduced to near zero and the Arabian Peninsula's oil pipeline network absorbing repeated attacks, energy markets face what the International Energy Agency has characterized as the most severe supply disruption in the organization's history.What Happened
The United States and Iran signed a memorandum of understanding on June 17 to restore commercial passage through the Strait of Hormuz. The agreement held briefly, allowing a modest recovery in crude tanker movements that averaged roughly 2 million barrels per day through the Strait in June and early July — a fraction of the 20 million barrels per day of oil and liquefied natural gas that transit the waterway under normal conditions, but enough to arrest the price climb.
The calm shattered when Iranian forces resumed attacks on vessels deemed noncompliant with Iranian routing demands, prompting fresh U.S. airstrikes and the reimposition of a naval blockade. Iran's Foreign Ministry stated directly: "As long as the U.S. naval blockade continues, the necessary conditions for the reopening of the Strait of Hormuz do not exist." The declaration effectively ended near-term resolution hopes, pushing Brent from the $72-per-barrel low recorded on June 26 — the session that reflected peak ceasefire optimism — back toward the $118 intraday high reached on April 29.
Oil Pipeline Disruption and Infrastructure Damage
The Strait is not the only pressure point. Saudi Arabia has reported that sustained attacks on its energy infrastructure have reduced production capacity by approximately 600,000 barrels per day and cut throughput on the East-West Pipeline — which carries crude from the Eastern Province to the Red Sea port of Yanbu — by roughly 700,000 bpd. The oil pipeline route had been positioned as a strategic bypass of Hormuz for Saudi crude exports, but damage to pumping stations and export terminals has significantly curtailed its ability to serve that function.
More than 3 million barrels per day of regional refining capacity has been shuttered due to attacks and the absence of viable crude tanker export routes. International buyers have pivoted toward alternative supply sources — including increased spot purchases from West African producers and U.S. Gulf Coast exporters — but logistical constraints and pricing differentials have prevented full substitution at the volumes required.
Market Reaction
WTI crude, the U.S. benchmark, tracked broadly in line with Brent on the session, reflecting tight global arbitrage conditions. Equity markets in major energy-exporting economies absorbed the move with relative calm. Airline, petrochemical, and freight-intensive sectors in consuming nations saw renewed selling pressure as input-cost assumptions were revised upward.Global oil supply has contracted by 10.1 million barrels per day to 97 million barrels per day, with approximately 10.5 million barrels per day of Gulf production currently offline — figures the IEA has described as the largest single-conflict supply reduction on record. The U.S. Energy Information Administration has confirmed that oil stockpiles in major consuming economies are headed toward their lowest levels since at least 2003, as governments draw down strategic reserves at a record pace to offset lost output.
Geopolitical Dimension
The conflict has fundamentally reordered the strategic calculus around Hormuz, which under pre-war conditions handled approximately 20% of global crude and gas trade. The June MOU had been interpreted by energy analysts as a potential turning point; senior U.S. and Iranian officials described its terms as a foundation for a more permanent arrangement. The resumption of crude tanker attacks extinguished that reading within weeks.
Israeli strikes in Lebanon have further complicated any broader de-escalation framework, raising doubts about the durability of any multilateral ceasefire architecture. Iran has cited three breaches of the existing agreement, complicating attribution and accountability. RBC Capital Markets notes that the ceasefire collapse has reignited energy risks beyond Hormuz, including threats to Saudi Red Sea exports, compounded by Russian refinery damage and accelerating inventory drawdowns elsewhere.
The IEA had projected Brent to average $86 per barrel across 2026, sharply above the $69 average recorded in 2025. That forecast now appears conservative.
What Comes Next
Diplomatic channels remain technically open. U.S., Iranian, and regional mediators were last reported to be exploring terms for a 45-day truce that could serve as a gateway to a more permanent arrangement. But the June MOU's rapid collapse has reduced market confidence in interim frameworks that do not resolve the underlying naval standoff.
At the supply level, OPEC+ members outside the Gulf conflict zone retain limited spare capacity. Non-OPEC producers, including U.S. shale operators, face infrastructure and capital constraints that preclude rapid output increases at the scale needed to offset losses of this magnitude.
