2nd November 2026
The price of Brent crude oil has fallen back to around $109 a barrel, offering some temporary relief after a period of considerable volatility in international energy markets. But should we welcome this as the beginning of a sustained reduction in oil prices, or is it simply the lull before another storm?.
For motorists, businesses, farmers and households already struggling with higher energy bills, the answer matters enormously. A sustained fall in oil prices would help ease inflationary pressures. However, there are several reasons why the latest decline should be treated with caution.
The oil market is currently being pulled in two opposing directions. Hopes of a diplomatic breakthrough between the United States and Iran are helping to bring prices down, while continuing disruption to oil supplies from the Middle East is creating the possibility of another sharp increase.
The fundamental problem is that the international oil market remains vulnerable, even if traders are temporarily feeling more optimistic.
Why has the price fallen?
The latest fall in Brent crude has largely been driven by renewed diplomatic activity involving Iran, Qatar and the United States.
There are growing hopes that negotiations could eventually lead to an agreement that allows shipping through the Strait of Hormuz to return to something approaching normality.
The Strait is one of the world's most important energy shipping routes. Before the conflict, approximately one-fifth of global oil consumption passed through it. Any prolonged interruption therefore has consequences far beyond the Middle East.
Iran has indicated that it could reopen the shipping route under certain conditions, but there is no confirmed agreement with Washington. The proposals involve substantial political and security issues, and there is no guarantee that negotiations will succeed.
Consequently, the market is responding to the possibility of an improvement rather than a confirmed restoration of normal supplies.
That distinction is important. Oil prices can fall rapidly when traders believe a crisis is approaching an end, but they can rise just as quickly when those expectations are disappointed.
The depletion of global oil reserves is becoming a serious concern
Perhaps the most worrying development is what has happened to the world's oil inventories during the disruption.
On 2 November, the chief executive of Abu Dhabi National Oil Company, Sultan Al Jaber, warned that nearly one billion barrels of oil had been drawn from global inventories since the disruption to shipping through Hormuz.
He also highlighted the particularly worrying position of diesel stocks, which in some regions have fallen to their lowest seasonal levels for 35 years.
This matters because inventories provide an important buffer when production or transportation is interrupted. When stocks are plentiful, the market can absorb a temporary supply problem. When those stocks have been substantially depleted, even a relatively small additional disruption can have a disproportionate effect.
The International Energy Agency has also warned about the deterioration in global supplies. Its September assessment reported that observed oil inventories had fallen by approximately 507 million barrels compared with their position at the beginning of the conflict.
The agency warned that if supplies from the Gulf remain constrained and inventories continue falling, higher prices and reduced consumption may eventually be necessary to balance the market.
In other words, the world has been using up its reserves to compensate for oil that is not reaching international markets.
That cannot continue indefinitely.
Diesel could be an even bigger problem than crude oil]/b]
There is a tendency to concentrate on the headline price of Brent crude, but the price of refined products can tell a different story.
Diesel is particularly important because it powers much of the transport, agricultural, construction and industrial economy.
Trucks deliver supermarket supplies, tractors operate farms, fishing vessels require fuel and construction machinery depends heavily on diesel. Higher diesel prices eventually feed into the cost of producing and distributing almost everything.
The latest warnings about depleted diesel stocks should therefore concern governments and businesses.
Even if crude oil prices fall, diesel prices may not follow immediately. Refining capacity, shipping costs, insurance and the availability of particular fuel products all influence the final price.
This is one reason why consumers can sometimes see little immediate benefit when international crude prices decline.
The International Energy Agency has been taking steps to address the shortage, including releasing additional diesel from emergency stocks. However, emergency reserves are intended to provide temporary protection, not replace normal production and distribution.
[b]Is OPEC+ able to help?
The major oil-producing countries also have an important role to play.
On 1 November, seven key OPEC+ members, including Saudi Arabia, Russia, Iraq, Kuwait and Algeria, agreed to maintain their December production targets rather than introduce another increase.
The decision reflects the considerable uncertainty surrounding the market. Although producers have been attempting to increase output during 2026, the conflict has prevented several countries from exporting at their intended levels.
There is little point announcing higher production targets if the oil cannot be transported safely to international customers.
OPEC+ will meet again on 29 November to consider its production arrangements for 2027. That meeting could become particularly important if diplomatic negotiations produce a breakthrough and disrupted supplies begin returning.
There is a possibility that the market could eventually move from a shortage towards a surplus if Gulf exports recover and production increases.
But that is a future possibility rather than something that can be relied upon today.
What does this mean for Britain?
Britain is particularly exposed to international energy prices because oil is traded in a global market.
Although the UK still produces oil and gas from the North Sea, domestic production does not insulate consumers from international price movements.
A rise in crude prices affects the cost of petrol, diesel, aviation fuel and heating oil. It also creates wider inflationary pressures through transport, manufacturing and distribution.
For businesses already dealing with higher wages, borrowing costs and other operating expenses, another increase in fuel prices could prove extremely difficult.
The consequences are particularly relevant to rural Scotland.
In Caithness and Sutherland, many households do not have access to mains gas and depend on heating oil or other forms of energy. They are therefore exposed to movements in international fuel markets in ways that households connected to the gas network may not be.
Farmers, hauliers, fishermen and small businesses also face higher operating costs when diesel prices increase.
There is a further complication. Even when crude prices decline, the savings do not necessarily reach consumers immediately. Refining margins, wholesale fuel prices, exchange rates and distribution costs all influence what motorists eventually pay at the pump.
The same applies to heating oil, where local delivery costs and the timing of purchases can make a significant difference.
Could another price shock push inflation higher?
This is where the oil market becomes an economic issue rather than simply an energy story.
The Bank of England has to consider the possibility that higher energy prices could reignite inflation just as policymakers are trying to bring it under control.
If oil prices rise again, the immediate effect would be higher fuel costs. But the consequences would spread through the economy.
Transport companies could increase their charges, manufacturers could pass on higher production costs and food prices could come under renewed pressure.
That could make it more difficult for the Bank of England to reduce interest rates.
The difficulty is that increasing interest rates cannot produce more oil or reopen shipping routes. It can suppress demand elsewhere in the economy, but it cannot directly resolve a shortage caused by geopolitical disruption.
This is an uncomfortable position for policymakers because an energy-driven inflation problem can leave households facing higher prices and higher borrowing costs at the same time.
Could prices fall substantially if peace returns?
There is certainly a more optimistic scenario.
If negotiations between Washington and Tehran succeed, shipping through the Strait of Hormuz could gradually return to normal. Oil exports could recover, insurance costs could fall and the supply of crude and refined products could improve.
That would remove a substantial amount of the uncertainty currently built into oil prices.
However, even a diplomatic agreement would not immediately restore the global energy market to its previous position.
Production facilities, shipping arrangements and supply chains may take time to recover. Inventories would need replenishing, and the effects of several months of disruption would continue to influence prices.
There is also the possibility that weaker economic activity and higher prices will reduce oil demand, helping to bring the market back into balance. But that would not necessarily be good news for businesses or employment.
The danger of assuming the crisis is over
The fall in Brent crude to around $109 is welcome, but it should not be mistaken for a resolution of the underlying energy crisis.
There are three possible directions from here.
A successful diplomatic settlement could bring prices down considerably. A prolonged period of uncertainty could leave oil trading around current levels, with considerable volatility. A renewed military escalation or further damage to energy infrastructure could send prices sharply higher again.
A return towards $120 or $130 a barrel would be entirely possible in a serious escalation, although nobody can reliably predict how far prices might rise.
The depletion of global inventories makes the situation particularly concerning because the market has less protection against another supply interruption.
The next few weeks will therefore be important. Traders will be watching developments around Hormuz, the progress of negotiations, the recovery of oil exports and the condition of global diesel inventories.
For Britain, the lesson is that energy security cannot simply be measured by how much oil and gas the country produces. The ability to obtain, transport, refine and distribute energy during an international crisis is equally important.
The latest fall in oil prices gives households and businesses some breathing space. But with global reserves depleted and the Middle East situation unresolved, it would be unwise to assume that the worst is behind us.
The oil market may have become calmer, but the underlying storm has not necessarily passed.
