U.S.-Iran exchanges keep Hormuz shipping low and lift oil risk premium

Renewed U.S.-Iran military exchanges have left commercial traffic in the Strait of Hormuz low as of 4 September, while oil prices reflect a higher perceived risk to Middle Eastern supply routes.

02

U.S. advisory keeps Strait of Hormuz shipping threat level high

A U.S. maritime advisory remains active through September 9, assessing the risk of Iranian attacks on commercial shipping in the Persian Gulf, Strait of Hormuz and Gulf of Oman as high and imposing detailed operating guidance on U.S.-flagged vessels.

03

U.S.-Iran fighting keeps Hormuz shipping disruption acute

As of September 3, U.S.-Iran military exchanges are sustaining a high-risk operating environment around the Strait of Hormuz, where commercial transits remain below reported pre-conflict levels and Iranian missiles and drones were intercepted over Kuwait.

04

US-Iran exchange heightens Hormuz transit risk

A renewed U.S.-Iran military exchange has spread to U.S. positions and Gulf states, raising acute but unquantified risks to shipping and energy movements through the Strait of Hormuz.

05

US defers planned Iran strikes as Hormuz access contacts remain unconfirmed

As of August 4, the United States is holding off planned major strikes against Iran while seeking a possible arrangement on Strait of Hormuz access, but Iran has confirmed only Oman-mediated discussions on safe navigation rather than direct talks with Washington.

06

Kuwait and Gulf shipping face fresh attacks as US pressure on Iran continues

As of August 1, Kuwait is responding to drone attacks and maritime-security reporting has recorded a vessel strike and a separate explosion report off Oman, while Washington maintains that Iran will face continued costs without meaningful talks.

07

US-Iran strikes resume as Hormuz talks fail to restore normal shipping conditions

US-Iran missile exchanges continued on July 30, while talks on normalising conditions in the Strait of Hormuz had not produced a rapid settlement and commercial traffic remained severely disrupted as of July 31.

08

US-Iran strike pause holds, but Hormuz transit remains unresolved

As of 27 July, the reported three-day pause in direct US-Iran attacks is holding while mediation continues, but commercial passage through the Strait of Hormuz remains constrained and subject to competing Iranian and US actions.

09

US-Iran escalation sustains Iranian port blockade and suppresses Hormuz traffic

As of July 19, the reported US blockade of Iranian ports remains operative amid continuing US-Iran strikes, regional missile and drone activity, and sharply reduced shipping through the Strait of Hormuz.

10

Iran suspends interim-deal commitments as Hormuz conflict risk intensifies

Iran said on July 18 it had suspended implementation of commitments under its interim arrangement with the United States, while a seventh consecutive night of US strikes, Iranian attacks on Gulf infrastructure and fresh attacks on merchant vessels heightened risk around the Strait of Hormuz.

11

U.S. struck Iran and reimposed tighter oil-sales restrictions after Hormuz ship attacks, as Iran retaliated against Bahrain and Kuwait

After reported attacks on three commercial ships in the Strait of Hormuz, the United States struck Iranian targets early on 8 July and replaced its earlier Iran oil-sales authorization with a wind-down measure, while Iran retaliated against Bahrain and Kuwait and tanker turn-backs extended the disruption.

12

US and Iran reportedly restored a halt on attacks and set Qatar talks after renewed Hormuz escalation

As of 29 June 2026, the current governing development was a reported US-Iran agreement on 28 June to halt renewed attacks and resume talks in Qatar, even as shipping security around the Strait of Hormuz remained unstable after fresh strikes, a vessel attack, and regional spillover to Bahrain and Kuwait.

13

Iranian attacks on Bahrain and Kuwait widened the Hormuz escalation after new U.S. strikes

By 28 June 2026, reported Iranian drone and missile attacks on Bahrain and Kuwait after fresh U.S. strikes had widened the Strait of Hormuz confrontation and further disrupted the 23 June U.S.-Iran shipping de-escalation framework.
