Experts warn that the near shutdown of the Strait of Hormuz, a key global shipping route, could lead to shortages of essential medicines and food in the UK. Weeks of disruption could trigger price hikes and supply gaps at a time when the NHS and British farmers are already struggling with soaring costs.
Strait of Hormuz: A Choke Point Under Siege
The Strait of Hormuz, a narrow passage linking the Persian Gulf to the Gulf of Oman, handles about 20% of the world’s oil supply. Roughly 130 ships pass through daily, ferrying oil, food, medicines, and other goods. The recent conflict with Iran has almost halted traffic through this crucial route. According to maritime trackers, around 700 vessels, including 400 oil tankers, are stranded in the area. Attacks on ships have become commonplace, prompting shipping companies to reroute or halt journeys altogether.
Capt. Silke Lehmköster, who manages a 300-strong fleet for shipping giant Hapag-Lloyd, has witnessed first-hand the dangers: her ships were ordered to stop due to threats from Iran’s Revolutionary Guard, with one vessel catching fire near Dubai after an attack. Uncertainty and risk have driven freight costs up and disrupted supply chains worldwide.
Medicine Supplies on a Knife-Edge
Britain imports about two-thirds of its medicines, with India supplying roughly a third of those, especially generic drugs and active pharmaceutical ingredients. India’s pharmaceutical industry, known as the “pharmacy of the world,” is facing export challenges because of the conflict and limited air and sea routes.
David Weeks from Moody’s highlights the "perfect storm" of geopolitical tension and supply chain disruption. Air freight costs have doubled since hostilities escalated, and with many medicines transported by air for speed, including cancer drugs and treatments for infectious diseases, the price pressure is mounting.
But pharmaceutical companies operate on thin margins, and absorbing extra costs is becoming unsustainable.
Mark Samuels, head of Medicines UK, warns that although the UK isn’t in a crisis yet, the situation is serious. The NHS requires suppliers to hold eight weeks’ worth of stock, but medical distributors typically keep only six to eight weeks of inventory. If the conflict drags on, shortages of common drugs—ranging from painkillers to cancer treatments—could emerge within weeks.
Food Supplies Feeling the Strain
Food supply chains are also under threat. Fuel is essential not only for transporting food but also for producing it. Fertiliser, a key input for crops and livestock, relies heavily on natural gas, and the skyrocketing energy prices caused by the conflict are pushing production costs up.
Prof Tim Lang, an expert on food security, says the UK and the world have yet to see the full impact of a major shock to the energy system. Food price inflation in England could double, he suggests, as farmers and producers grapple with higher costs for fuel, fertiliser, and energy to heat greenhouses and chicken barns.
The National Farmers’ Union president, Tom Bradshaw, confirms that UK farm businesses are under growing pressure. Dairy producers face added difficulty as fertiliser prices rise and supply becomes unpredictable just as pasture growth peaks in spring. Horticulture firms are caught between rising heating costs and increased energy standing charges.
Speciality foods from Iran, such as pistachios and saffron, are already affected. Iran accounts for the majority of the world’s saffron supply and a large share of pistachio exports, so disruptions risk shortages and price rises in these niche markets.
Wider Economic Implications
Energy markets remain volatile.
The Strait of Hormuz blockade has pushed global oil prices higher, which in turn drives up costs for goods dependent on oil-based transport and production. Because the UK depends heavily on imports, it is especially vulnerable.
Even if the fighting stops tomorrow, the effects will still be felt for some time. Shipping schedules have been disrupted, insurance premiums for vessels in the region have surged, and manufacturers face longer lead times. The fragility of global supply chains has been exposed once again, with the UK caught in the middle.
Bob McNally, a former White House energy adviser, points out that Iran doesn't need to completely close the strait. Simply threatening or demonstrating the capacity to attack ships is enough to keep prices high and shipping routes uncertain. That uncertainty feeds through to consumer prices, affecting everything from petrol at the pump to the cost of groceries and medicines.
For the NHS, which already operates on tight budgets, price hikes could force difficult choices. Suppliers may pass on increased costs to pharmacies and GP practices, potentially leading to higher prices for patients. The government faces the challenge of securing supply chains while managing inflationary pressures on households.

With disruptions likely to last weeks, the UK faces rising costs and shortages that could affect everyday items like paracetamol and pistachios. The closure of the Strait of Hormuz is more than a regional flashpoint — it's a test of how resilient Britain’s food and medicine supply chains really are.
