A tense silence hangs over the Strait of Hormuz. Commercial shipping is staying away. The Royal Navy is on high alert. And the reason is the price of bread on the kitchen table in Stoke, in Sunderland, in Southampton. The global oil price has already twitched, and analysts fear a sustained closure of this vital chokepoint would push fuel costs through the roof, hitting household budgets within weeks.
So why are ships not passing through? Three factors are driving the standoff.
First, the shadow war. The initial triggers are familiar: tit-for-tat seizures, suspected drone attacks, and a ratcheting up of rhetoric between Tehran and Washington. The latest incident involved the detention of a tanker, triggering a British frigate to shadow it for days. The UK Foreign Office has warned of 'consequences,' but for the crews and the owners, the immediate fear is a boarded vessel or a drifting mine. For a family in Manchester running a car on a tight budget, that faraway standoff translates into a ripple of higher insurance premiums on cargo, then higher prices at the pump.
Second, the cost of insurance has soared. Marine underwriters have quadrupled the premiums for Gulf transits. For a shipowner, a single voyage through the Strait now carries a risk premium that eats into margins. Many simply calculate that the profits from a legitimate passage are not worth the possibility of a 30-day detention, a legal battle, or a missile strike. This is not an act of high politics. It is a simple business calculation. But when combined, these calculations drain the supply of tankers reaching Europe, squeezing refineries that supply our forecourts.
Third, the warning from history. The 2019 tanker seizures are still fresh in operational minds. Then, the UK was forced to deploy the navy just to guarantee freedom of navigation. Today, Defence Secretary Ben Wallace has already confirmed that HMS Duncan is in the region. The message is clear: a Royal Navy presence might deter a direct attack, but it cannot force a commercial ship to sail if the owner decides to wait and see. The uncertainty itself acts as a barrier. Each ship that turns around or waits outside the Gulf adds to the backlog, and the longer the delay, the tighter the supply of crude on the global market.
What does this mean for Britain’s cost of living? The UK is a net importer of oil. Any disruption to the 20 million barrels a day that pass through the Strait directly affects the price we pay for petrol, diesel, heating oil, and the transport costs embedded in every loaf of bread and pint of milk. The Petrol Retailers Association has already warned that if the situation worsens, pump prices could rise 5p to 10p a litre within a week. For a household already struggling with high inflation, that is another cut to disposable income.
Ministers are quick to blame a volatile world, but the truth is that the UK’s vulnerability is a result of years of domestic neglect. We have closed our refineries, we have shrunken our strategic storage, and we have outsourced our energy security to the whims of the Gulf. The answer is not just a British frigate, but a serious policy to insulate families from shocks: a windfall tax on profiteering oil firms that is actually spent on insulation, on public transport, on support for the poorest.
For now, the Royal Navy will do its duty. The tankers may wait. But for the mother in Middlesbrough filling her car, the threat of disruption is already here. The Government must act, not just to patrol the seas, but to protect the people who pay the price.
