The UK government announced on Tuesday that it will offer to host an international security summit aimed at developing a "viable, collective plan" to reopen the Strait of Hormuz. The announcement came on the same day that fresh PMI data showed the Iran war is actively stalling the British economy, with business activity slowing, domestic and international orders falling, and input costs surging to levels not seen since the 2022 energy crisis.
The summit proposal is an attempt to circumvent the UN Security Council deadlock, where Bahrain's Chapter VII resolution authorising "all necessary means" to reopen the strait faces a Russian veto and Russia's softer alternative faces an American one. Britain is positioning itself as a diplomatic broker — a role it has not played at this level since the Falklands War — and betting that enough countries will attend to create momentum outside the UN framework.
The Economic Pressure
The urgency is not abstract. A monthly survey of business activity across the UK showed a marked slowdown in output alongside falling domestic and international orders. Economists warned that a "pronounced recession" would follow if energy prices remain elevated. The war's impact on Britain is transmitted primarily through energy costs: oil above $100 a barrel feeds directly into petrol prices, heating bills, transport costs, and food prices. The energy price cap, already forecast to jump 20% in July, could rise further if the strait remains closed through the summer.
Chancellor Rachel Reeves told the Commons that contingency planning was underway for "every eventuality," a formulation that covers everything from targeted support for vulnerable households to emergency price controls. The government has not specified what those contingencies are, and the Treasury's reluctance to be more precise suggests that the options are either expensive, politically painful, or both.
The Military Dimension
Behind the diplomatic language, British defence chiefs are working on something more concrete: plans for how a multinational naval force could physically unblock the strait. The Royal Navy already has a permanent presence in the Gulf, and HMS Queen Elizabeth is reportedly en route to the region. But clearing a strait that Iran has mined, blockaded, and is actively defending with anti-ship missiles is not a naval escort mission. It is a combat operation, and one that would put British forces in direct conflict with Iran.
The government has been careful to frame the summit as a diplomatic initiative, not a military one. But diplomacy without the credible threat of force is a conversation, and Iran has shown no inclination to reopen the strait through conversation alone. The summit's real purpose is to build the political coalition that would be needed if force becomes necessary — to ensure that any military operation to reopen the strait is multinational, legally defensible, and not just an Anglo-American adventure.
The Public Mood
A new poll released on Wednesday found that 40% of people in the UK believe the country will be at war within five years. More than two-thirds said they would be unable to cope in a conflict. Over half believed Britain was poorly prepared for war. The survey, published to coincide with the launch of a private resilience initiative, captures a public mood that has shifted dramatically since the Iran war began: not panic, but a quiet, pervasive anxiety that the world has become more dangerous and that Britain is not ready for what comes next.
The government's challenge is to address that anxiety without amplifying it. Hosting a Hormuz summit signals seriousness. Deploying the carrier strike group signals readiness. But neither signal answers the question that most voters are actually asking: how much worse is this going to get, and what is it going to cost me? Reeves's promise to plan for "every eventuality" is an honest answer. It is not a reassuring one.
