Latest Market Alert | 20 July 2026
Executive Summary
Brent crude rose above US$90 per barrel as renewed United States–Iran hostilities caused another sharp reduction in shipping through the Strait of Hormuz. Reuters reported that only four vessels crossed the Strait on Sunday, compared with eight on Saturday, while no liquefied natural gas (LNG) tankers had passed through the waterway since Thursday.
The United States has continued military strikes against Iran and is enforcing a naval blockade affecting Iranian ports, while Iran has warned vessels it considers to be breaching its navigation requirements.
Why it matters
The Strait of Hormuz remains one of the world’s most strategically important energy corridors, normally handling around one-fifth of global oil trade. Even without a complete physical closure, the combination of military activity, vessel restrictions and increased war-risk premiums is making routine commercial navigation increasingly difficult.
The interruption to LNG movements is particularly significant because production and loading at Qatari and UAE export terminals have continued, resulting in a build-up of laden vessels and unused tanker capacity within the Gulf.
UK impact
UK businesses face renewed exposure to higher energy prices, increased marine and aviation insurance premiums, longer transport routes and further inflationary pressure.
European gas markets may also become more volatile if Qatari LNG cargoes remain unable to leave the Gulf. Organisations reliant upon international manufacturing or transport should review whether suppliers are passing higher fuel, freight and insurance costs through existing contracts.
Global impact
Higher oil prices are already influencing inflation expectations and financial markets worldwide. Gulf producers have increased the use of alternative export routes where available, including Saudi Arabia’s Red Sea facilities, but these cannot fully replace the export capacity normally provided by the Strait of Hormuz.
Our View
The market should not assess disruption solely by asking whether the Strait is formally open or closed. A shipping lane can remain technically open while becoming commercially inaccessible because of military activity, insurance restrictions and operational risk.
Businesses with Gulf exposure should review marine war-risk insurance, political violence cover, force-majeure provisions, alternative logistics arrangements and contractual responsibility for increased transport costs.
