Brent crude climbs above $106 a barrel as attacks on commercial vessels intensify. British motorists, farmers and households facing another expensive winter could feel the consequences.
Oil prices are rising again as a fresh wave of attacks on commercial shipping in and around the Strait of Hormuz increases fears of further disruption to global energy supplies.
Brent crude, the international benchmark, rose to around $106.58 a barrel on Wednesday, 14 October, while US crude also moved higher. The increases reflect growing concern about the security of oil shipments from the Middle East, alongside attacks on Saudi Arabian targets and continuing uncertainty over the wider conflict.
According to Reuters, at least five incidents involving commercial ships were reported within 48 hours as Iran stepped up efforts to disrupt maritime traffic. The Financial Times has reported that 24 ships were attacked during the two weeks leading up to 11 October, the highest number over a comparable period since the conflict began.
These are not simply incidents involving ships passing through a dangerous stretch of water. They threaten one of the world's most important energy supply routes.
Why the Strait of Hormuz matters
The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the wider Indian Ocean. Before the current conflict, roughly one-fifth of global oil and liquefied natural gas supplies passed through this narrow waterway.
When ships are attacked, the consequences extend well beyond the vessels involved. Shipowners may refuse to enter the area, insurers may demand substantially higher premiums and tanker operators may charge more to accept the risks.
Even when oil is available at the production end, getting it to refineries and customers can become more expensive and less reliable.
The scale of the disruption has already been substantial. Shipping data reported by the Financial Times showed that oil exports through the strait fell to approximately 2.9 million barrels a day on 11 October, compared with a September peak of 15.5 million barrels a day.
That does not mean every barrel has disappeared from the market. Some supplies can be redirected through alternative routes, while producers can increase output where spare capacity and infrastructure permit. But replacing the lost shipments is neither immediate nor straightforward.
Why oil prices are reacting again
Oil prices are influenced by both current supply and expectations about what might happen next.
A further attack can send prices higher because traders fear that more ships will be prevented from sailing, oil infrastructure could be damaged or the conflict could spread to additional countries and transport routes.
Brent crude had already risen sharply in recent weeks. Reuters reported a price of $105.69 a barrel at Tuesday's close, before it climbed to around $106.58 during Wednesday's trading.
There are factors that could limit further increases. OPEC+ producers have raised output, and the prospect of additional Russian diesel exports could ease some pressure on fuel markets. But additional production cannot necessarily compensate for every disruption in shipping, refining and distribution.
The market is therefore caught between efforts to increase supplies and the risk that conflict will prevent those supplies reaching their destinations.
Diesel could be a particular problem
For British consumers, crude oil prices are only part of the story.
Diesel supplies are already under pressure, and the cost of moving fuel around the world has risen sharply. The price of diesel depends on refinery capacity, available stocks, shipping costs and demand, as well as the price of crude oil itself.
This matters because diesel is central to road haulage, agriculture, construction and many industrial activities.
If wholesale diesel prices rise, hauliers may face higher operating costs. Those costs can eventually be passed on to businesses and consumers through delivery charges and the prices of goods.
Farmers face a similar problem. Higher diesel prices increase the cost of operating tractors, harvesting crops and transporting produce. If energy and fertiliser costs also rise, the pressure on food producers becomes greater.
The consequences may take time to appear on supermarket shelves, but fuel is an important input into almost every stage of the food supply chain.
Heating oil households face another worry
For households in rural Scotland, the concern is particularly immediate.
Many homes in Caithness and Sutherland rely on heating oil rather than mains gas. Their costs are influenced by wholesale oil prices, local supply conditions, transport and delivery charges, and the margins charged by suppliers.
A rise in Brent crude does not translate directly or immediately into the same percentage increase in heating oil. Nevertheless, a prolonged disruption to international supplies could add further upward pressure at a time when households are preparing for winter.
Those who have already paid substantially more to refill their tanks will be watching developments closely. Households that have delayed ordering may find themselves facing difficult decisions if prices rise further.
The impact will not be the same for everyone. Some people can absorb higher bills or reduce their consumption. Others have little room in their budgets, particularly families with children, pensioners and people who need to keep their homes warmer for health reasons.
Can governments prevent another price surge?
Governments and oil-producing countries have several options, including increasing production where possible, releasing strategic reserves and working to keep shipping routes open.
But none provides a complete solution if attacks continue and shipowners are unwilling to accept the risks.
The recent increase in OPEC+ production offers some support to the market, while the prospect of extra Russian diesel supplies may help ease shortages. However, these measures cannot guarantee lower prices if the conflict continues to disrupt transport and infrastructure.
Diplomatic progress could quickly reduce the risk premium built into oil prices. Equally, a major escalation or a prolonged reduction in shipping could push prices higher.
That makes forecasting difficult. It would be premature to predict a particular price for Brent crude, petrol or heating oil. What can be said is that the risks remain elevated.
The cost of energy depends on more than the price of oil
The latest attacks underline an uncomfortable reality for Britain. Even a country that produces energy of its own remains exposed to international markets, global shipping routes and events thousands of miles away.
North Sea production, renewable electricity and energy-efficiency improvements can all help reduce particular vulnerabilities. But oil remains essential to transport, agriculture and many industrial processes, while households that depend on heating oil remain exposed to movements in the wider market.
For Caithness and Sutherland, where long journeys and limited alternatives can make transport more expensive, another sustained rise in fuel costs could have consequences for household budgets and local businesses alike.
The immediate question is whether the latest attacks prove to be a temporary interruption or part of a longer period of unreliable shipping.
If vessels return to the route and exports recover, some of the upward pressure could ease. If attacks continue and oil shipments remain restricted, the effects could spread through diesel, heating oil, freight and food costs over the coming weeks and months.
The warning is clear: the world does not need a complete closure of the Strait of Hormuz for energy prices to rise. It only needs enough disruption to make supplies more expensive, uncertain and difficult to deliver.
For British households and businesses already struggling with high costs, that is a risk worth watching closely.
