The United Kingdom government is preparing contingency plans for potential food shortages as the ongoing conflict involving Iran continues to disrupt global supply chains, particularly in a worst case scenario where the Strait of Hormuz remains closed for an extended period.
According to senior officials, the planning is precautionary rather than predictive, but it reflects growing concern over how prolonged geopolitical tensions could ripple into everyday life, including the availability of key food products such as chicken and pork.
The Strait of Hormuz is one of the most critical arteries for global oil and gas transport, handling a significant portion of the world’s energy supply. Its disruption has already driven up fuel prices worldwide, creating knock on effects across multiple industries. For the UK, the implications go beyond energy costs and into the food supply chain, which is heavily dependent on stable fuel and fertiliser markets.
One of the less obvious but crucial risks highlighted in government planning is the potential shortage of carbon dioxide. CO2 plays a vital role in food production, particularly in the humane slaughter of animals and in preserving perishable goods. A breakdown in CO2 supply could therefore disrupt meat processing and storage, even if raw food supplies remain available.
Despite these concerns, government officials have been quick to reassure the public that there is no immediate crisis. Business Secretary Peter Kyle stated that “the availability of CO2 was not a concern for the British economy at this moment,” urging citizens to continue normal activities without panic.
Major retailers have echoed this message. Ken Murphy, the chief executive of Tesco, said that the company’s supply chains remain stable and that no suppliers have flagged shortages so far. “We are not seeing any availability issues. We are in very good shape,” he noted, although he acknowledged that the situation remains unpredictable.
The uncertainty stems from the broader economic impact of the conflict. Fuel and fertiliser costs have surged since the escalation began, increasing the cost of food production globally. Farmers are particularly exposed, as fertiliser prices are closely tied to energy markets, and transport costs affect every stage of the supply chain, from farm to supermarket shelves.
The International Monetary Fund has already warned that the conflict could push the global economy toward recession, with the UK expected to be among the hardest hit advanced economies.
Within the UK, early signs of pressure are beginning to emerge. The National Farmers’ Union has cautioned that prices for certain produce, including cucumbers and tomatoes, could rise within weeks, while other products such as milk may see increases over the coming months. These projections highlight how quickly global disruptions can translate into domestic price changes.
In response to potential CO2 shortages, the government has already taken steps to stabilise supply by restarting the Ensus bioethanol plant, which produces carbon dioxide as a by product. The facility had previously been shut down after changes in trade policy made imports more competitive, but the current crisis has forced a reassessment of domestic production capacity.
The situation also carries political implications. Rachel Reeves has criticised the breakdown in diplomatic negotiations, describing the shift toward military action as a “mistake.” Meanwhile, Donald Trump has suggested that talks aimed at ending the conflict could resume, offering a potential pathway to de escalation.
For now, the UK remains in a state of heightened vigilance rather than emergency. Supply chains are holding, supermarkets are stocked, and officials insist there is no immediate threat to food availability. But the existence of contingency plans reveals a deeper reality: modern food systems are highly interconnected and vulnerable to global shocks.
If the conflict persists and the Strait of Hormuz remains closed, the UK could face a combination of rising food prices, logistical challenges, and targeted shortages in specific sectors. The extent of the impact will depend on how long the disruption lasts and how effectively governments and industries adapt.
What is clear is that the situation underscores the fragile balance of global supply systems. A conflict thousands of miles away has the potential to influence what appears on supermarket shelves in Britain, reminding policymakers and consumers alike of the far reaching consequences of geopolitical instability.
