Prime Minister Sir Keir Starmer and US President Donald Trump have agreed on the pressing requirement to reopen the Strait of Hormuz after a telephone call on Sunday evening, as the vital shipping route continues to be effectively blockaded by Iran. Traffic through one of the world’s most heavily used shipping lanes has plummeted by approximately 95% since hostilities escalated on 28 February, threatening global energy stability. A Downing Street spokesperson verified the leaders “confirmed that opening the Strait of Hormuz was vital to safeguard stability in the international energy sector”. The political engagement occurs as crude oil prices have surged 45% to $106 a barrel, with roughly one-fifth of the world’s oil and liquefied natural gas usually flowing via the strait. Sir Keir is preparing to chair a Cobra crisis session on Monday to assess the conflict’s consequences for British household expenses.
The turmoil affecting international energy markets
The closure of the Strait of Hormuz has created disruption through international oil markets, with crude oil prices surging sharply since Iran’s near-total blockade of the waterway. The 45% increase to $106 a barrel constitutes a substantial rise that threatens to ripple through global economies. With roughly one-fifth of the world’s crude oil and LNG normally flowing through this critical chokepoint, the near-complete halt of traffic has created an unprecedented supply crunch. Energy analysts caution that prolonged instability could trigger wider inflation concerns, particularly affecting families already grappling with high cost of living and businesses dependent on reliable energy access.
The economic implications extend far beyond oil prices, touching everything from heating bills to transport costs and manufacturing expenses. The UK government has already acted to address immediate pressures, with Housing Secretary Steve Reed announcing a £53 million support package for homes facing sharp increases in heating oil prices. However, officials accept that sustained disruption could exert sustained upward pressure on inflation throughout the economy. The Bank of England governor will attend Monday’s Cobra meeting specifically to assess these wider economic risks, as policymakers address the challenge of shielding British households and businesses from the fallout of Middle Eastern instability.
- Crude oil prices have climbed 45% since the blockade started on 28 February
- One-fifth of worldwide oil and liquefied natural gas normally transits the strait
- UK authorities offering £53 million assistance programme for fuel oil support
- Price increases threaten household budgets and business supply chains nationwide
Diplomatic tensions mounts on Tehran
The crisis has intensified international strain among Western nations and Iran, with international figures now actively considering methods to compel the return to normal operations at the Strait of Hormuz. Prime Minister Sir Keir Starmer and President Donald Trump have emphasised the issue in senior-level talks, acknowledging that prolonged blockade jeopardises global economic stability. Their coordinated position indicates a collaborative effort to compelling Iran into restoring passage via the strait. The conversation between the two leaders underscores the seriousness with which Western governments view the situation, with both accepting that reopening the strait is vital for stabilising global energy markets and avoiding further economic damage.
Beyond bilateral discussions, the UK government is activating its internal crisis response systems to tackle the fallout. The Monday Cobra meeting represents a coordinated cross-government strategy, uniting leading cabinet figures responsible for energy, foreign affairs, and economic policy. Officials are examining the full spectrum of possible effects, from domestic power costs to business supply chains and inflation pressures. The involvement of Bank of England governor Andrew Bailey highlights official concern about broader economic ramifications. Ministers are said to be weighing various policy options, though the government has stayed silent about particular actions under discussion to shield British households and businesses from escalating costs.
Trump’s demand and Iran’s reply
President Trump has assumed a confrontational posture, making a clear warning on social platforms that he would “obliterate” Iranian power plants if the Strait of Hormuz is not reopened within two days. This final warning represents an escalation in rhetoric and demonstrates Washington’s determination to tackle the closure quickly. The statement emphasises the Trump administration’s willingness to apply military leverage as leverage against Tehran, indicating that diplomatic channels alone may not suffice to restore passage through the vital waterway.
Iran has responded to Trump’s threat with counter-threats of its own, with Tehran alerting via state media that it would strike US-linked energy sites throughout the Gulf region if American military action proceeds. This cycle of escalation raises the spectre of further regional conflict and potential strikes on critical infrastructure. The Iranian response demonstrates Tehran’s resolve to uphold its blockade despite international pressure, creating a volatile deadlock that threatens to worsen the global energy crisis further.
Britain prepares internal economic plan
The British government is acting swiftly to address the economic fallout of the Middle East conflict, recognising that sustained disruption to the Strait of Hormuz poses a genuine threat to UK households and businesses. With crude oil prices already surging 45 per cent to $106 a barrel, officials are deeply mindful that continued escalation could spark inflation concerns that ripple through the entire economy. The critical importance of the moment is reflected in Sir Keir Starmer’s choice to call a top-tier Cobra gathering on Monday, assembling the nation’s most leading officials to formulate a coordinated response.
The government’s approach shows a resolve to safeguard British residents from the most severe impacts of international energy supply disruption. Housing Minister Matthew Pennycook stated that officials are “very conscious of the threats” posed by the conflict, especially concerning rising pressure on inflation. The extensive scope of the response—encompassing the Bank of England governor, the chancellor, and senior cabinet officials—underscores the importance with which Whitehall is handling anticipated economic impacts. Ministers are carefully examining policy approaches to reduce cost-of-living impacts, though the government has chosen not to reveal specific measures being considered at this time.
Emergency Cobra gathering takes place Monday morning
- Bank of England governor Andrew Bailey on hand to examine macroeconomic implications
- Chancellor, foreign secretary and Secretary of State for Energy taking part in talks
- Energy security and cost-of-living impacts on families priority matters
- Business supply chains and global coordination response under review
- Policy options under consideration to protect households from rising price impacts
Support measures already in place
The government has already begun implementing support measures to help vulnerable households cope with energy costs. A £53 million package has been deployed to support homes experiencing steep rises in heating oil prices, showing immediate action on an pressing issue. Housing Secretary Steve Reed stressed the government’s dedication to “standing behind” the British people during this challenging period. These measures represent an first step, though ministers are evidently developing further measures for potential discussion at Monday’s Cobra meeting should the Middle East situation deteriorate further.
Military buildup and security threats
The intensifying military strains encircling the Strait of Hormuz have triggered concern across major Western cities. President Trump’s Saturday declaration to “eliminate” Iranian power plants if the waterway is not restored to passage within two days amounts to an unprecedented level of dangerous posturing. In reaction, Tehran has threatened to strike US-connected energy assets throughout the Gulf region, according to Iranian state media. This back-and-forth posturing has significantly raised the risk of military engagement between the United States and Iran, with potentially catastrophic repercussions for international fuel supplies and regional peace.
The Israel Defense Forces revealed on Saturday that Iran has weapons capable of reaching targets up to 4,000 kilometres away, underscoring the genuine military capability underpinning Tehran’s threats. Intelligence assessments indicate that Iran has shown both the technological sophistication and apparent willingness to use long-range missiles in recent strikes. This capability gap has sparked pressing talks between British and American leadership about de-escalation strategies and emergency preparedness. The combination of military posturing, economic leverage, and strategic miscalculation risks has created an extremely unstable situation that requires careful diplomatic handling.

| Iranian retaliation threat | Tehran warned it would target US-linked energy sites across the Gulf region if threatened |
| Strait blockade | Iran has effectively blocked the waterway since US and Israel attacks on 28 February |
UK base participation and ballistic threats
British military bases in the Gulf region have become inadvertent focal points in the escalating crisis. The Israel Defense Forces earlier stated that Iranian missiles had struck at the shared American-British facility at Diego Garcia, a critically important installation in the Indian Ocean. This disclosure led Foreign Secretary David Lammy to criticise what he characterised as “reckless Iran threats.” The participation of UK armed forces in the conflict zone has heightened domestic security concerns and highlighted the immediate consequences of Middle Eastern instability for British strategic priorities and personnel deployed overseas.
Despite the concerning military developments, UK authorities have attempted to convince the public about immediate threats. Housing Secretary Steve Reed stated there is “no specific evaluation that the Iranians are focusing on the UK—or even could if they wanted to.” This balanced comment reflects official belief in Britain’s defensive capabilities and intelligence reports. However, the admission that Iranian missiles can travel far enough to theoretically strike British territories has led to increased alertness among defence organisations and military planners monitoring the situation closely.
