Another escalation in the Middle East threatens to add to the pressure on diesel, petrol, heating oil and the cost of living. The danger lies not just in the attacks themselves, but in what happens to the oil supplies the world depends on.
The latest Houthi attacks on Saudi Arabia have raised another uncomfortable question for households and businesses already struggling with high energy costs: are oil prices about to rise again?
The answer depends on what the attacks damage, whether they continue and how far the conflict spreads. But with oil markets already unsettled by the wider Middle East conflict, the danger is that another supply shock could push prices higher just as Britain heads into winter.
The consequences would be felt well beyond the Middle East. Higher oil prices can feed through to the cost of filling a car, heating a home, transporting goods and producing food. For rural communities such as Caithness, where people often have little choice but to drive and many homes depend on heating oil, another increase could be particularly unwelcome.
Why Saudi Arabia matters so much
Saudi Arabia is one of the world's most important oil producers and exporters. Its ability to maintain production and move crude oil to international markets is a major factor in keeping the global oil market supplied.
That makes attacks on Saudi infrastructure particularly worrying. There is a considerable difference between an attack that causes limited damage and one that disrupts production, damages export facilities or prevents oil tankers from loading their cargoes.
Oil markets react not only to the barrels actually lost, but also to the possibility that supplies could be interrupted in the days or weeks ahead.
Traders may therefore bid prices higher before the full extent of any disruption is known. If the damage proves limited and oil continues to flow, some of that increase may subsequently disappear. If exports are seriously affected, however, the consequences could be much greater.
The danger extends beyond Saudi Arabia
The Houthi movement, based in Yemen, has previously attacked shipping and targets associated with the regional conflict. Its actions have helped make the Red Sea and surrounding waters a more difficult environment for commercial shipping.
The wider concern is that the conflict could threaten several parts of the oil supply chain at once.
The Strait of Hormuz, between Iran and Oman, is one of the world's most strategically important oil shipping routes. Large quantities of crude oil and other petroleum products pass through it every day. Any sustained interruption would create a serious challenge for importing countries.
Saudi Arabia has an alternative route. Its East-West pipeline can carry crude oil across the country towards the Red Sea, reducing its dependence on the Strait of Hormuz. But this is not a complete solution. Pipeline capacity is limited, and the alternative export route and its facilities can also face security risks.
The more routes and facilities that are threatened simultaneously, the harder it becomes for the global market to replace lost supplies quickly.
Could oil prices surge?
There is no reliable way to predict the price response from the number of attacks alone. The scale of the damage, the duration of any interruption and the availability of alternative supplies will determine the outcome.
If Saudi production and exports continue largely unaffected, prices could remain volatile without a sustained further increase.
If major facilities are damaged and exports fall, oil prices could rise by several dollars a barrel or more. A wider disruption affecting important Gulf shipping routes could produce a much sharper surge.
Brent crude, the international benchmark, was reported at around $104 a barrel in early trading on Monday, 12 October. That figure reflects the wider market situation, rather than the Houthi attacks alone. Prices can move in either direction as traders assess the balance between supply risks and the prospect of additional oil becoming available.
The important point is that the market does not need to lose all its supplies to experience a sharp price increase. When spare capacity is limited or uncertainty is high, even the threat of a disruption can have an effect.
Diesel could be a particular problem
For British consumers, the price of crude oil is only part of the story.
Diesel is essential to road haulage, farming, construction and many other industries. If wholesale diesel prices rise, transport businesses may seek to recover the additional expense through higher charges. Those costs can eventually reach consumers through the prices of food, building materials and other goods.
Farmers face a double pressure. They need diesel to operate machinery and move produce, while energy costs can also affect fertiliser manufacture and other agricultural inputs.
There is a possible counterweight. If additional supplies of refined fuel become available from elsewhere, diesel prices may be less affected than crude oil prices alone would suggest. But that depends on where the fuel comes from, how easily it can reach Britain and whether competing buyers are prepared to pay more.
It is therefore worth watching wholesale diesel prices as well as Brent crude. A fall in crude does not automatically mean an immediate fall in the price displayed on a garage forecourt.
Heating oil and the approach of winter
The implications are particularly serious for households that rely on heating oil.
Unlike motorists, who can often buy fuel in relatively small quantities, heating oil customers may need to pay for hundreds of litres at a time. A sudden increase in the price per litre can therefore mean a substantial additional bill.
The relationship between crude oil and heating oil prices is not exact. Refinery capacity, demand for heating fuels, transport costs, exchange rates and local delivery charges all play a part.
Nevertheless, a sustained rise in crude prices would add to the upward pressure on heating oil if it also pushed up the wholesale cost of the product.
For households in Caithness and elsewhere in rural Scotland, this is not an abstract international issue. Winter heating is a necessity, and many people have few practical alternatives to oil. Those with limited incomes may have little opportunity to absorb a sudden increase in the cost of filling their tanks.
The timing is particularly unfortunate. If prices rise sharply as colder weather increases demand, households could face the double problem of needing more fuel and paying more for every litre.
Could food prices rise again?
Energy costs have a habit of spreading through the economy.
A haulier paying more for diesel faces higher operating costs. A farmer paying more for fuel and fertiliser faces higher production costs. Manufacturers and distributors may face higher transport and energy bills.
Not every increase is passed on immediately, and businesses may initially absorb some costs themselves. But if higher fuel prices persist, pressure builds for increases elsewhere.
This is one reason an oil-price shock can continue affecting households long after the original headlines have disappeared. The price at the pump may change quickly, while the effect on shop prices can take weeks or months to emerge.
For families already coping with high household bills, even relatively modest increases across several areas of spending can make a difference.
What should we watch next?
There are four indicators worth following over the coming days.
First, whether Saudi Arabia confirms significant damage to production facilities, pipelines or export terminals. Second, whether the attacks continue and threaten additional infrastructure. Third, whether commercial shipping through the Red Sea and the Gulf faces further disruption. Finally, whether Brent crude and wholesale diesel prices rise together or begin to diverge.
These developments will tell us more than the headlines about individual attacks.
Governments can release strategic reserves or take other steps to help manage a supply emergency, but such measures cannot permanently replace large volumes of lost production. If a disruption lasts, the market must ultimately adjust through additional supplies, reduced demand or higher prices.
Another warning for Britain
Britain cannot control what happens in Yemen or Saudi Arabia. It can, however, recognise how vulnerable households and businesses are to events in distant parts of the world.
The latest attacks do not guarantee another oil-price surge. If Saudi production and exports remain secure, the immediate impact may be limited. But the combination of regional conflict, vulnerable shipping routes and expensive fuel means the risks should not be dismissed.
For Caithness, where driving is often unavoidable and heating oil remains important, the effects could be felt particularly keenly if prices rise again.
The uncomfortable lesson is that the cost of energy is influenced by much more than what happens at a local petrol station or oil depot. It is also shaped by wars, shipping routes, infrastructure and the decisions of governments thousands of miles away.
The question is not simply whether the latest attacks will push oil prices higher. It is whether the world is entering a period in which repeated disruptions make expensive energy a more persistent feature of everyday life.
If that happens, the consequences will reach far beyond the oil market.
