The UK has offered to host an international summit aimed at reopening the Strait of Hormuz, which carries roughly a fifth of the world's oil supply. Because of the war in Iran, that flow is effectively paralysed, and has deterred shipping and rattled global markets.
The disruption follows escalating tensions between Iran and a US-Israeli alliance, with Tehran signalling it could target vessels in retaliation.
Defence officials in London are under no illusion that oil prices have surged. Gas costs have followed. The Strait of Hormuz, long recognised as a geopolitical fault line, has once again proved how quickly it can transmit crisis far beyond the Gulf.
Against that backdrop, British ministers are attempting to assemble what they describe as a 'viable, collective plan' to restore safe passage.
Behind-The-Scenes Military Planning
UK military planners have already been dispatched to US Central Command to explore options for escorting or protecting tankers navigating the strait. Discussions among allied defence chiefs have centred on practical interventions, among them the potential deployment of minesweeping drones to clear hazards and reassure commercial shipping.
More than 30 countries, including the United Arab Emirates, France, Germany, Canada, and Australia, have signed a joint statement committing to 'appropriate efforts' to safeguard the waterway. There is no interest in a full-scale naval build-up in a region already bristling with tension.
Western governments have reportedly resisted calls from Donald Trump to send additional warships while the situation remains volatile.
One defence official told The Guardian, 'There will be a further meeting, military to military, the chiefs of defence staff of the wider group that has now signed that [statement], and potentially inviting other nations that have not signed it, later this week. I anticipate that at some point in the near future there'll be some kind of Strait of Hormuz security conference.'
London, or possibly Portsmouth, home to the Royal Navy, has been floated as a host.
The ambition, as described, is to build momentum quickly enough that when conditions allow, a coordinated effort can reopen a safe corridor for shipping.
Political Pressure At Home And Abroad
For UK Prime Minister Keir Starmer, he warned there may be no 'quick and early end' to the conflict, even after the US delayed planned strikes on Iranian power infrastructure.
Meanwhile, criticism is sharpening within Westminster. Matt Western, Labour MP and chair of the Joint Committee on national security strategy, described the current trajectory of US policy as among the 'most foolhardy and costly' for the global economy.
Western accused both 'trigger-happy' Trump and Israeli Prime Minister Benjamin Netanyahu of pursuing a 'catastrophic military folly' that is 'crippling the global economy and hurting the pockets of British consumers'.
'Trump and Netanyahu's catastrophic military folly is crippling the global economy and hurting the pockets of British consumers. Despite this government's best efforts, we are still heavily dependent on oil and gas,' he said at Monday's parliamentary meeting.
'About 20% of the world's oil passes through the Strait of Hormuz, which is the busiest oil shipping channel in the world. And it is at a virtual standstill. As expected, the price of energy has skyrocketed. Gas prices have almost doubled, and the price of oil has jumped,' he added.
What emerges from this moment is less a clear strategy than a fragile convergence of necessity. The UK's proposed summit is, in essence, an attempt to impose order on a situation where military, economic, and diplomatic pressures are pulling in different directions.
