• A senior Iranian official tells Reuters the Strait of Hormuz will remain closed and nuclear negotiations with the U.S. will not resume until Washington meets Tehran's conditions.
  • Iran has signaled through intermediaries that it could reopen the strait and restart talks within seven days if the U.S. eases military pressure, ends the blockade of Iranian ports, and addresses sanctions-related demands.
  • The standoff has crippled global energy flows, with Hormuz traffic plummeting from 18 million barrels per day before the conflict to just 2 million bpd so far in August, sending Brent crude above $100.

A Conditional Closure

Iran is holding the world's most critical energy chokepoint hostage to a broader diplomatic settlement, according to a senior Iranian official who spoke to Reuters. The official said the Strait of Hormuz will remain closed and that Tehran will not engage in nuclear talks with Washington until its conditions are met—a stance that links maritime access directly to the nuclear file and U.S. sanctions relief.

But the position is not as absolute as it first appears. Foreign Minister Abbas Araghchi has reportedly indicated that Iran could reopen the strait and restart nuclear negotiations within seven days of the U.S. accepting its terms, with Qatar serving as an intermediary. The sequencing, however, remains the central dispute: Iran wants the strait and the blockade issue resolved before substantive nuclear discussions, while Washington has preferred to focus talks on the nuclear program rather than treating maritime access as the primary subject.

"What we are seeing is a deliberate bargaining strategy," said one person familiar with the mediation efforts, who asked not to be named discussing sensitive diplomacy. "Tehran wants to front-load the concessions it values most."

Shipping Disruption Deepens

The human and economic toll is mounting. Flows through Hormuz have collapsed from roughly 18 million barrels per day before the conflict to 4.8 million bpd in July and about 2 million bpd so far in August, according to Reuters. The International Energy Agency has characterized the broader disruption as the largest supply shock in oil-market history, with cumulative Middle East supply losses exceeding 1.3 billion barrels.

The strait is pivotal not just for crude but for liquefied natural gas, especially Qatari shipments. In 2025, about 19% of global LNG trade transited Hormuz. Tanker owners, insurers, and refiners are grappling with rerouting, elevated war-risk premiums, and what traders describe as "dark" transits—vessels moving through unofficial, high-risk routes with transponders off.

"The physical cargoes can still move in some cases, but the financing, insurance, and scheduling costs have exploded," said a Geneva-based shipping executive. "This is not a normal market."

Regional Diplomacy Fragile

Qatar and other mediators have sought to convene talks in Oman, but the effort remains delicate. Saudi Arabia and the United Arab Emirates have reportedly urged Washington not to ease pressure before a broader agreement, fearing that a premature reopening would reward Tehran without addressing security concerns.

The International Atomic Energy Agency's monitoring has also become a serious concern. Director General Rafael Grossi said the agency has conducted virtually no in-field verification activities in Iran for more than six months, except for an inspection of the Bushehr plant in June. The IAEA also lacks continuity of knowledge concerning previously declared uranium inventories, including material enriched to 60%.

Market Reaction and Economic Stakes

Oil markets have priced in a long-duration structural risk. Crude stabilized around $90 per barrel in August—still roughly 50% above the start of the year—before mid-September reporting put Brent above $100 amid further disruption. One recent report said Brent fell more than 2% toward $98 after Iran indicated a possible reopening, underscoring how much of the current price is geopolitical premium rather than physical shortage.

The economic exposure is global but asymmetrical. About 80% of oil and oil-products transiting the strait in 2025 were destined for Asia. Higher import bills can worsen trade balances, inflation, and fiscal pressure on fuel subsidies. The World Bank reported that Brent rose about 65% by the end of March after the conflict began, alongside a global oil-supply fall of 10.1 million bpd in March. The Congressional Budget Office estimates that prolonged war-related energy disruption could add roughly 0.5 percentage point to U.S. inflation in early 2027.

A Durable Settlement Remains Elusive

Even a reopening of shipping would not resolve the wider crisis. A durable agreement would likely need to address maritime safety, sanctions, military de-escalation, nuclear verification, and the sequencing of concessions—a matrix of issues that has defied resolution for months.

The IEA has warned that the combined disruption to oil and gas flows and regional energy infrastructure has major implications for energy security, affordability, and the world economy. Brookings cautions that even after reopening, physical markets may take months to normalize because tanker scheduling, insurance, supply contracts, inventories, and routing networks cannot reset instantly.

Iranian officials did not respond to requests for comment on the specifics of the negotiations. A U.S. State Department spokesperson said Washington remains committed to diplomacy but declined to comment on the sequencing of talks.

Correction: An earlier version of this article misstated the date of the IAEA's last inspection of the Bushehr plant. It was in June, not July.
