Strait of Hormuz closure 2026: 6% oil rebound, talks hit wall

What changed overnight in the Gulf

Tensions between the US and Iran escalated again after Tehran said it would not participate in the next round of planned talks in Pakistan and signalled that the Strait of Hormuz is closed again. A senior Iranian official, Ebrahim Zolfaghari, said Iran has rejected negotiations with the US, adding that any peace deal is now cancelled and the strait is fully closed again. The update came soon after US President Donald Trump said a second round of talks would be held on Monday in Pakistan. Iran’s position, carried by Iranian media, linked its decision to the presence of a naval blockade.

The developments matter because the Strait of Hormuz is a critical shipping lane for global oil flows and any disruption quickly feeds into crude prices and freight costs. The live updates also pointed to shipping incidents near the strait involving Indian-linked vessels, adding a diplomatic dimension for New Delhi.

Iran’s stance on Pakistan talks

Iran declined to participate in the planned second round of talks with the United States, according to Iran’s state news agency IRNA. The report blamed “excessive demands and unreasonable, unrealistic requests” from the US for stalling progress. Separately, Iran’s Tasnim news agency said Tehran has not decided to send a negotiating delegation to Pakistan “as long as there is a naval blockade.”

IRNA also cited the US naval blockade of Iranian ports and what it described as “threatening rhetoric” as obstacles to talks. A separate update said Iran’s deputy foreign minister stated that no date has been set for the next round of negotiations and that discussions need an “understanding framework.”

Trump’s warnings and US negotiating position

Trump issued a warning on Truth Social, saying the US would strike Iran’s bridges and power plants if Tehran rejects the US peace deal. In the same messaging, he said the US was running down on patience and would not be a “nice guy” any more. In another update, Trump described the negotiations as a “last chance” for Iran to agree to a peace deal.

Trump told Fox News that Tehran must act quickly to avoid serious consequences, and he drew a contrast with the 2015 nuclear agreement signed under former President Barack Obama. In additional remarks cited in the live coverage, Trump said, “If Iran does not sign this deal, the whole country is getting blown up,” while also saying he believed the sides were “very close” to a deal.

The ceasefire clock and the disputed violations

The live updates said a two-week ceasefire agreement was reached on April 8, with the truce set to conclude on Wednesday, April 22. Reports in the feed said both the US and Iran accused the other of violating the ceasefire by attacking ships over the weekend. The renewed friction around ship safety and the strait’s status has increased uncertainty over whether the ceasefire can be extended.

Iranian Parliament Speaker Mohammad Bagher Ghalibaf said Tehran is seeking a “lasting peace” ahead of the ceasefire deadline. But multiple updates also described deep mistrust and disagreements over red lines during earlier negotiations.

Strait of Hormuz: closure, control claims, and new restrictions

Iran’s IRGC was cited as saying that control of the Strait of Hormuz has reverted to its previous state due to a US blockade. The IRGC accused the US of piracy and said strict management would continue until full freedom of navigation is restored. In another update, Iran’s First Vice President Mohammad Reza Aref said “security of Strait of Hormuz is not free,” linking maritime security to restrictions on Iran’s oil exports.

A separate report said Iran would prioritise vessels willing to pay fees for crossing the strait under new maritime restrictions. The update described a “pay or wait” approach, where vessels that do not pay could face delayed passage.

Incidents at sea and India’s diplomatic response

The live feed reported that Iranian gunboats fired on a tanker in the Strait of Hormuz, forcing two Indian vessels to reverse course. One was described as an Indian-flagged VLCC supertanker carrying 2 million barrels of Iraqi oil. India summoned Iran’s ambassador in New Delhi after the incidents, expressing “deep concern” and urging Iran to facilitate safe passage for ships bound for India.

Separately, an update said Iranian forces launched drones toward US warships after an Iranian commercial vessel was attacked in the Sea of Oman, citing Al Jazeera and Iranian media. Press TV, citing Mehr, reported that the IRGC claimed US forces in the Sea of Oman were forced to retreat after firing at an Iranian merchant vessel.

Oil market reaction: sharp moves in both directions

Oil prices rebounded more than 6% on Monday after falling more than 9% on Friday, according to the live updates. The rebound followed news that the Strait of Hormuz was closed again and that the ceasefire was under strain. In another market update, Brent crude rose 4.4% to settle at $19.36, and was described as well above roughly $10 from before the war.

Another price snapshot in early trading said Brent crude futures gained 0.87% to $16.75 a barrel, while West Texas Intermediate futures were up 1.06% at $18.91 a barrel. The feed also reported oil climbing above $100 a barrel as the US Navy prepared to block ships to and from Iran.

Key facts at a glance

Market impact for energy, shipping, and risk pricing

The reported closure of the Strait of Hormuz and the US move to enforce a maritime blockade from April 13 are central drivers of the oil price reaction described in the live feed. Higher crude prices can reflect both expected supply constraints and elevated risk premiums linked to shipping disruptions and conflict escalation. The reported fee-based crossing rules and gunfire incidents add operational uncertainty for tanker traffic, which can feed into freight rates and insurance costs.

The updates also show how quickly prices can swing on conflict headlines, with a steep fall followed by a sharp rebound. Even as oil climbed in some snapshots, the feed noted that price moves later moderated, suggesting markets were still trying to assess how durable the restrictions and threats would be.

Why the breakdown in talks matters

The reports highlight two parallel pressures on negotiations: hard security measures at sea and the widening list of contested demands. US officials were cited as saying there was no agreement on multiple red lines, including uranium enrichment and broader regional de-escalation conditions. Iranian state media, in turn, described US demands as unreasonable and linked Iran’s refusal to the ongoing blockade and rhetoric.

With the ceasefire deadline approaching and no confirmed date for a next round of talks, the situation described in the live feed leaves shipping safety and energy pricing highly sensitive to official announcements and on-water incidents.

What to watch next

The live updates point to several near-term markers: the April 22 ceasefire deadline, any confirmed rescheduling of US-Iran talks, and how maritime restrictions are enforced in and around the Strait of Hormuz. Further official statements from Washington, Tehran, and regional mediators such as Pakistan are likely to be the next catalysts for crude prices and shipping sentiment.
