On 7 July 2026, the United States Treasury revoked General License X, ending the temporary sanctions relief for Iranian-origin oil, petroleum products and petrochemical products. The move followed reported attacks on commercial tankers in or near the Strait of Hormuz and renewed United States military strikes against Iranian targets. Although the 60-day ceasefire framework agreed in June remains formally relevant, its status is contested. The security and sanctions risk to vessels operating in the region remains high irrespective of that framework. 

Impact on cover or operations 

On 7 July 2026, the United States Treasury revoked General License X and replaced it with General License X1. General License X had temporarily authorised transactions involving the production, sale, delivery and offloading of Iranian-origin crude oil, petroleum products and petrochemical products until 21 August 2026. General License X1 supersedes that authorisation, prohibits new transactions involving Iranian-origin petroleum on or after 7 July 2026, and permits only transactions ordinarily incident and necessary to wind down previously authorised activity. That wind-down authorisation expires at 12:01 am Eastern Daylight Time on 17 July 2026. Payments owed to blocked persons must be deposited into a blocked, interest-bearing account in the United States. 

The sanctions change occurred alongside renewed military escalation. United States Central Command has stated that it struck targets in Iran in response to attacks on three commercial vessels transiting the Strait of Hormuz. Further strikes reportedly followed on 8 July. Iran is also reported to have launched missiles and drones against United States military sites in Bahrain and Kuwait, although United States officials indicated that these were intercepted or caused no major damage. 

The affected vessels have been publicly described as including a Qatari-owned liquefied natural gas carrier, a Saudi-flagged crude tanker and a third commercial vessel. The vessel names have deliberately been omitted from this Alert. Qatar and Saudi Arabia have condemned the attacks. Iran has not formally claimed responsibility, although Iranian state media has indicated Iranian involvement. 

The memorandum of understanding signed on 17 June 2026 established a 60-day ceasefire framework, extendable by mutual consent, under which further talks were to address sanctions relief and Iran’s nuclear programme. It remains a framework rather than a final peace agreement. Following the events of 7 and 8 July, the United States has stated that the memorandum is over, while mediators including Pakistan and Qatar have indicated that engagement continues. A continuing dispute also concerns navigational rights, with Iran requiring vessels to use a northern route closer to the Iranian coast, a position rejected by United States Central Command. 

The escalation materially heightens the risk to vessels operating in the region and bears directly on War Risks cover, which is subject to specific terms and notice periods for calls in Listed Areas. Market reporting indicates that oil prices rose following the attacks and that traffic through the Strait remains below pre-war levels. Any projections concerning rerouting or reduced Arabian Gulf cargo volumes should be treated as scenario analysis rather than confirmed developments. 

Crew welfare 

Crew welfare remains a primary operational consideration. The Secretary-General of the International Maritime Organization has called for maximum restraint and urged shipowners, operators and flag States to avoid transits where the safety of seafarers cannot be assured. United Nations reporting indicates that thousands of seafarers remain aboard vessels delayed in or near the Strait as a result of the deteriorating security situation. 

Members should ensure that voyage planning takes account of the evolving threat environment, safe ports of refuge, crew fatigue, medical assistance, evacuation and crew-change contingencies. Owners operating vessels subject to collective bargaining agreements should also consider any provisions applicable to designated warlike areas. 

War risk 

The deterioration in the security environment has been reflected in the marine war-risk market. Following renewed attacks on commercial shipping and uncertainty surrounding the ceasefire framework, insurers have reversed much of the post-ceasefire easing in pricing. War-risk premiums for Strait of Hormuz transits have increased again, and underwriting decisions are increasingly being made on a voyage-by-voyage basis. 

The Club has been notified that war risk buy-back terms for Strait of Hormuz transits have been cancelled and replaced with revised terms with effect from midnight on 9 July 2026. Under the revised arrangements, quotations are valid for a limited period only, transits must commence within a short window of binding, and terms are subject to short notice of cancellation and amendment. 

Members should anticipate closer scrutiny when placing war-risk cover, including requests for updated voyage information, routing, cargo details and mitigation measures. Premiums and terms may change quickly and should not be assumed to reflect the position following the June framework agreement. 

Operations 

Commercial traffic continues to move through the Strait of Hormuz, but operational conditions remain highly uncertain. Large commercial vessels have reportedly reduced movements through the established transit corridor, while enhanced naval activity, security warnings and the possibility of further attacks continue to affect confidence in the route. 

Members should review pre-voyage risk assessments immediately before transit, take account of the latest UKMTO and naval advisories, and maintain contingency plans for route deviations, delays and disruption. Operational decisions should be based on current maritime security information rather than statements regarding the status of the ceasefire. 

Recommended action 

Members must exercise extreme caution when considering any voyage to or through the Arabian Gulf and the Strait of Hormuz, irrespective of the status of the ceasefire framework. 

Members may contact their underwriters before committing to any voyage in the region to confirm the status of their Protection and Indemnity and War Risks cover. War-risk terms for Strait of Hormuz transits have hardened, are now quoted on a voyage-by-voyage basis with limited validity, and are subject to short notice of cancellation. 

Members should conduct enhanced, voyage-specific risk assessments based on the most current security intelligence, including the continuing routing dispute in the Strait. 

This Alert is issued for the general information of Members and does not constitute legal advice or a determination of cover in any individual case. Members should refer to the terms of their entry and contact the Club for case specific guidance.
