Iran on Saturday laid out sweeping demands for the United States to reopen the Strait of Hormuz, according to media reports, shortly after Abu Dhabi's National Oil Company (ADNOC) said one of its vessels was targeted by a missile while transiting the strategic waterway.

The Secretary of Iran's Supreme National Security Council, Mohammad Bagher Zolghadr, said Saturday that reopening the strait would require Washington to lift its naval blockade and sanctions, withdraw U.S. military forces from the region, pay war reparations, and release frozen Iranian assets. The council also called for an end to U.S. attacks on Iran's regional allies and to threats against Iran. CNBC has not independently verified the demands, and the White House did not immediately respond to a request for comment.

Interim Deal and Negotiation Timeline

According to the interim deal signed in June between the U.S. and Iran, a schedule to end sanctions and a compensation plan would be part of a final agreement, as would negotiations to address frozen assets. The 60-day period agreed upon to negotiate a final deal is set to expire in just over a week. Without an extension or finalized agreement, the parties would face the prospect of either prolonged stalemate or renewed escalation, leaving commercial shipping and energy markets in continued uncertainty.

A brief hiatus in fighting following a June 17 memorandum of understanding was followed by weeks of attacks and counterstrikes between the U.S. and Iran, with Tehran targeting several of its Gulf neighbors with missiles and drones.

ADNOC Vessel Targeted

ADNOC said in a statement that the missile incident "resulted in no injuries, and the situation has been brought under control." The United Arab Emirates, of which Abu Dhabi is the capital, said in a post on X that it "condemns in the strongest terms the targeting of an ADNOC-affiliated tanker while it was passing through the Strait of Hormuz."

The strike on an ADNOC-affiliated vessel underscores the vulnerability of Gulf energy producers, who rely on the strait to export the bulk of their crude oil and liquefied natural gas to global markets.

Iran-Oman Management Discussions

Separately, Iran said it was close to reaching a deal with Oman to manage the strait, the Associated Press reported. Iranian Foreign Minister Abbas Araghchi said earlier Saturday that the two countries, which border the waterway, were close to an agreement on navigation, "specifically the determination of a transit route." Oman has historically served as a mediator between Iran and Western governments, including during the negotiations that led to the 2015 Iran nuclear agreement.

Oman said in a statement that discussions were ongoing "in a positive and constructive atmosphere," and condemned attacks on ships in the strait.

U.S. Vice President JD Vance, in an interview with Fox News on Saturday, said Iran and its Gulf neighbors, particularly Oman, had been discussing how to ensure the safe flow of traffic through the strait. Plans include a traffic scheme, demining the waterway, and a commitment from Iran not to fire on commercial vessels.

"We don't trust. We verify," Vance said, adding that the U.S. would judge Iran by its actions rather than its words.

Iran and Oman are working on an agreement under which inbound traffic would transit Iranian waters while outbound traffic would go through Omani waters, according to media reports.

Conflicting Signals from Tehran

"The reopening of the Strait of Hormuz is subject to the specific mechanism and conditions of the Islamic Republic of Iran and has nothing to do with the negotiations between Iran and Oman," Sardar Mohbi, a spokesman for Iran's Islamic Revolutionary Guard Corps, said in a statement on Telegram translated by Google. The statement from the IRGC, which operates independently of Iran's civilian government on security matters, appeared to contradict the foreign ministry's account of progress with Oman, illustrating the competing centers of power within Iran's political system.

Iranian state media published a draft plan Thursday that would restrict traffic through Hormuz. The plan is under review by Iran's parliament, according to the state outlet Fars. Under the draft, Iran would ban U.S. and Israeli ships from transiting the strait. Other nations that have harmed Iran would not be allowed to transit until compensation is paid.

U.S. Officials Signaled Imminent Deal

Treasury Secretary Scott Bessent told CNBC on Tuesday that an agreement to open Hormuz with freedom of movement could come as soon as Wednesday. President Donald Trump and Secretary of State Marco Rubio had also indicated that an agreement was imminent. However, no deal has been announced.

On Thursday, Iran's chief negotiator accused Trump of staging "theater diplomacy," as Washington and Tehran offered conflicting accounts of bilateral engagement aimed at ending their monthslong hostilities.

"'Massive attack coming … wait, never mind, they want to negotiate.' That's theater diplomacy on loop," Mohammad Bagher Ghalibaf, Iran's parliament speaker and top negotiator, wrote in a post on X on Thursday, in an apparent jab at Trump.

The remarks came days after Trump called off planned strikes and said the outlines of a deal had already been settled with Tehran. Iranian officials have rejected the claim, saying no talks were underway.

Impact on Shipping and Oil Markets

Tehran's ability to effectively close the strait — an open, untolled international waterway before the U.S.-Iran war started on Feb. 28 — has triggered a global energy supply shock that has driven up gas prices, exacerbated inflation, and raised alarms about oil reserves. The strait normally carries roughly one-fifth of the world's daily oil consumption, making it one of the most consequential maritime chokepoints for global energy trade.

Ship traffic through Hormuz was down 33% on Friday compared to the day prior, with most vessels using the Iranian route, according to trade intelligence firm Kpler.

Oil prices rose Friday as investors waited for an agreement teased by the Trump administration earlier in the week. Brent crude futures, the international benchmark, gained more than 1% to close at $83.55 a barrel. U.S. West Texas Intermediate advanced about 1% to settle at $78.18 per barrel. Prices fell more than 7% for the week.

The conflict continues to broaden across the region, with Gulf energy infrastructure and key shipping choke points under renewed threat.
