Brent Crude Plunges 13% as Middle East Diplomacy Eases Supply Fears, but $140 Oil Risk Remains

Brent Crude Falls Sharply as Middle East Diplomacy Raises Hopes, but Supply Risks Remain

Brent crude oil prices have suffered one of their sharpest weekly declines in years as growing hopes of a diplomatic breakthrough in the Middle East have encouraged investors to reduce the risk premium that had pushed oil prices higher.

The international benchmark fell to around $98 a barrel, marking a dramatic reversal after months of elevated prices caused by concerns over disruptions to oil production and shipping in the region. Brent's weekly decline was the steepest since the early stages of the COVID-19 pandemic, highlighting just how quickly market expectations have changed. Reuters reported that Brent was on track for a decline of around 17% over the week, while other market measures put the weekly fall at about 16%.

The sharp decline has been driven largely by hopes that diplomatic efforts could reduce tensions involving Iran and other parties in the Middle East. However, the situation remains highly uncertain. Attacks on oil-carrying vessels continue, while disruptions to regional energy infrastructure remain a significant threat to global supplies.

Diplomacy changes the oil market's mood

For much of the recent period, traders have been concerned that escalating conflict in the Middle East could remove large volumes of crude from the international market. Those fears pushed oil prices higher and created what analysts call a geopolitical risk premium.

That premium represents the additional amount traders are willing to pay because of the possibility of a disruption to future supplies.

As diplomatic signals have improved, some of that premium has disappeared. Investors are increasingly betting that negotiations could eventually lead to reduced military activity, safer shipping routes and the restoration of oil exports.

The change in sentiment was particularly visible after political developments in the United States increased expectations of a possible reduction in the risk of further escalation. Reuters reported that Brent fell sharply as investors interpreted the developments as potentially supportive of de-escalation in the US-Iran conflict.

The market's reaction shows how sensitive oil prices have become to diplomatic developments. Even before a formal peace agreement is reached, the possibility of one can be enough to influence traders' expectations.

Why oil prices could fall further

If diplomatic efforts succeed and the security situation improves, oil production and exports from the Middle East could gradually recover.

That would increase the amount of crude available to international buyers. More supply, combined with weaker demand caused by previously high prices, could put additional pressure on Brent.

Goldman Sachs has previously said its base case is for Middle Eastern oil supplies to recover gradually, which would eventually reduce crude prices. The bank has also warned, however, that renewed escalation could create significant upside risks.

The possibility of a growing global supply surplus is another factor weighing on prices. As more regional supplies return to the market, traders may become less worried about shortages and more concerned about excess crude.

This would represent a major shift from the supply-scarcity fears that dominated the market earlier in the conflict.

Tanker attacks remain a major concern

Despite the oil price decline, there are still reasons for caution.

Attacks on vessels carrying oil and other energy products remain close to record levels. Reuters reported that 37 ships were attacked in October, the highest monthly total since the conflict began. The International Maritime Organization has also recorded numerous regional incidents since the conflict started, including deaths among seafarers.

The continued attacks are important because producing oil is only one part of the supply chain. The crude must also be transported safely to refineries and international customers.

The Strait of Hormuz is particularly important because of its role in global energy transportation. Any prolonged disruption around the waterway could affect shipments from major Gulf producers and create another surge in oil prices.

Recent attacks have already demonstrated how quickly the market can reverse direction. On November 5, Brent gained more than $3 a barrel after new tanker attacks revived concerns about supplies. Brent settled at $98.29 that day, showing that geopolitical developments can still produce major price swings even during a broader sell-off.

Goldman Sachs warns Brent could reach $140

The possibility of lower prices should therefore not be confused with the disappearance of the supply threat.

Goldman Sachs has warned that Brent crude could rise as high as $140 a barrel in 2027 under a severe supply-disruption scenario.

According to the bank, Brent could reach $140 and average around $130 in 2027 if Gulf oil production remains about 3.5 million barrels per day below its 2025 average. Goldman identified intensified shipping attacks, damage to oil infrastructure and a persistent geopolitical risk premium as potential triggers for such an increase.

Goldman has also raised its December Brent forecast to $105 a barrel from $90 and increased its 2027 average forecast to $88 from $80. The changes reflect the continuing uncertainty surrounding Middle Eastern supply.

This creates a striking contrast in the oil outlook. On one side, successful diplomacy and recovering production could push prices lower. On the other, continued attacks and prolonged production losses could send prices dramatically higher.

What lower oil prices mean for consumers

A sustained fall in crude prices could eventually benefit consumers around the world.

Lower crude prices generally reduce the cost of producing petrol, diesel, jet fuel and other petroleum products. However, changes in international crude prices do not always translate immediately into lower prices at filling stations.

Refining costs, transportation expenses, exchange rates, taxes and local market conditions all influence the final price consumers pay.

For oil-importing countries, a prolonged period of lower crude prices could reduce the cost of importing energy and ease pressure on inflation. Businesses that rely heavily on fuel and transportation could also benefit from lower operating costs.

Oil-producing countries, meanwhile, could face lower revenues if crude remains significantly below recent highs. Governments that depend heavily on petroleum income may have to adjust their budgets and spending plans.

Markets remain caught between optimism and risk

The recent decline demonstrates the difficulty of predicting where oil prices will go next.

Investors are currently responding to the possibility of diplomatic progress, but the underlying security situation has not been fully resolved. A successful agreement could encourage even more selling, particularly if oil production and exports return quickly.

But a breakdown in negotiations, new attacks on tankers or major damage to oil infrastructure could produce the opposite reaction.

The market has already shown how quickly prices can move in either direction. Brent dropped sharply as diplomatic hopes increased, only to rebound when tanker attacks raised fresh supply concerns.

For traders, therefore, the key question is not simply whether oil prices are falling today. It is whether the conditions behind the decline are strong enough to last.

The road ahead for Brent crude

Brent crude's move toward $98 a barrel represents a major change from the much higher levels seen during the height of supply fears. The decline suggests that investors are becoming more confident that the Middle East crisis could eventually ease.

However, the continuing attacks on oil-carrying vessels show that the physical risks to energy supplies remain serious.

The coming weeks could therefore be crucial. If diplomacy produces a durable agreement, crude prices could continue falling as supply disruptions ease and the geopolitical risk premium disappears.

If negotiations fail or attacks intensify, however, the recent sell-off could quickly reverse.

For now, the oil market is balancing two competing possibilities: a return to greater stability and lower prices, or renewed disruption that could send Brent sharply higher. With Goldman Sachs warning of a potential $140 price under a severe supply scenario, the recent decline may be significant, but it does not mean the risks have disappeared.
