Oil Risk Premium Explained — How Much War Risk Is in the Brent Price in 2026?

What is an oil risk premium?

A geopolitical risk premium is the part of the oil price that pays for what might happen, not for what has happened. Traders bid prices above the level that current supply and demand would justify. They do so because a war, a blockade or an attack could remove barrels later.

The premium is not a line item that anyone publishes. It is an estimate, and it depends on the model behind it. Analysts usually build a "fair value" from inventories, supply and demand, then compare it with the market price. The gap is read as the risk premium.

The US Energy Information Administration (EIA) links part of today's premium to shipping. It says the heightened risk to tankers in the region has raised freight costs and the risk premium in oil prices ^[19]. Freight, insurance and fear therefore tend to move together.

How do analysts estimate the premium?

Goldman Sachs is the most widely quoted source this year. In its 16 October note it put spot Brent nearly $25 a barrel above its estimate of fair value ^[1]. Daan Struyven, co-head of commodities research, linked it to the chance of further supply cuts and stock draws in an escalation ^[1].

The bank's view of fundamentals has improved. It estimates that Gulf exports are back near their 2025 average ^[1]. The global deficit narrowed to 0.3 million barrels a day (mb/d) in September, from 7.2 mb/d in March ^[1]. It expects a surplus from the fourth quarter. That is why it forecasts December Brent at $90 and a 2027 average of $80, well below current futures ^[1,2].

Goldman's estimates show how the premium has grown. In June 2025, with Brent at $76–77, it put the premium at around $10 ^[4]. On 2 March 2026, as the war began, it estimated about $18 ^[3]. Other houses use different models, so the figures are not directly comparable across banks.

How does the risk premium show up in the futures curve?

The clearest market signal is backwardation. That is when contracts for near delivery trade above those for later delivery. It tells you that buyers pay up for barrels now and expect supply to be easier later.

On 29 October the December Brent contract settled at $114.88 and January at $110.80 ^[6]. A market report from Commodity Board shows the same shape further out on 27 October. December 2026 Brent closed at $115.12, February 2027 at $106.10 and February 2037 at about $61.53 ^[7].

The curve also shows where markets think the risk ends. In late March, FTSE Russell's Indrani De noted that December Brent was 17% below the front month ^[9]. It was still about 10% above pre-war prices, she told CNBC ^[9]. She read that $10–12 gap as a risk premium built into the market ^[9].

Backwardation is not pure fear, however. Prompt spreads also reflect real shortages. On 14 July the first-month Brent contract traded $8.92 above the sixth month after renewed strikes ^[8]. Sparta Commodities' Neil Crosby called that move "largely a paper move" at the time, driven by investor flows ^[8].

What do options and implied volatility say?

Options prices show how large a move traders fear. The Cboe Crude Oil ETF Volatility Index (OVX) is built from the prices of options on an oil exchange-traded fund ^[10]. A higher reading means bigger expected swings in either direction.

The index closed at 120.91 on 11 March, its 2026 high ^[10]. It stood at 57.16 on 29 October ^[10]. That is well below the spring peak. It is still above the monthly averages of 33–36 from July to December 2025, on our calculation ^[10].

Oil volatility has moved apart from equities. On 8 July, after fresh US strikes, Saxo noted that OVX jumped 18% to 47.59 while the VIX equity gauge barely moved ^[11]. That pushed the OVX-to-VIX ratio to about 2.95 ^[11].

Skew adds detail. In October 2024 Goldman said options were pricing about a 5% chance of a $20 jump in Brent within a month ^[5]. Such probabilities are one way analysts translate option prices into a dollar premium.

What do Brent–WTI and Murban spreads reveal?

Regional spreads show where the risk sits. Brent is a seaborne benchmark, so it is more exposed to shipping disruption than inland WTI. When the war began, the Brent–WTI spread spiked to $18.65, OANDA's MarketPulse reported ^[15]. By 6 July, with the premium largely priced out, Brent traded at $71.97 and WTI at $68.68 ^[14].

The spread widened again in October. On 23 October Brent was $114.40 and WTI $100.90 ^[13]. On 29 October December contracts settled at $114.88 and $102 ^[6].

Murban, Abu Dhabi's flagship grade, loads at Fujairah outside the Strait of Hormuz ^[12]. In mid-September it traded above $127 while Brent was above $107 ^[12]. In early October it reached $110 with Brent just above $102 ^[13]. On 23 October the two traded level at $114.40, and by 26 October Murban was about $3.40 above Brent ^[13,12].

Gulf News suggests that barrels which avoid Hormuz are scarce and attract a premium whenever bypass routes look at risk ^[12]. The October swings show how quickly that premium can return.

How quickly do risk premiums fade?

History suggests fast, once supply is restored. After the September 2019 strikes on Abqaiq and Khurais, Brent closed 14% higher at $69.02 ^[16]. A day later it fell to $64.55 as Saudi Arabia restored half the lost output ^[17]. By 27 September it was only $1.58 above its pre-attack close of $60.22 ^[16]. The OVX followed the same path, rising from 35.48 to 48.58 and back to 38.90 within two weeks ^[10].

The 2025 and 2026 episodes followed a similar pattern. In June 2025 the OVX rose from 35.05 to 71.56 within a week, then fell back to 41.23 by 27 June ^[10]. In 2026 the US–Iran interim agreement triggered a sharp unwinding, PublicInvest said ^[18]. Brent fell from an intraday high of $126 to around $72 ^[18].

The difference now is duration. Each time the premium faded, it was because barrels came back, not because risk disappeared. Today's premium sits on top of depleted stocks, which Goldman says support prices on their own ^[1].

What could raise or remove the premium now?

• Diplomacy. Qatari mediators returned to Tehran on 30 October. CBS News reported that Iran was expected to respond to a revised proposal from the mediators ^[20]. A deal that reopened Hormuz would test Goldman's $25 estimate directly.
• The US midterms on 3 November. Rigzone reports that President Donald Trump has signalled the military campaign may resume after the elections ^[6]. TD Securities' Ryan McKay expects headlines on deal talks to keep weighing on crude into the vote ^[6].
• Attacks on infrastructure. Goldman calls renewed escalation against ports, pipelines or fields a significant upside risk ^[1]. It estimates Brent could average about $125 in 2027 if Gulf output stayed 5 mb/d below February 2026 levels ^[2].
• Supply recovery. Conversely, Goldman sees Brent in the $60s in 2027 if Gulf output rose 1 mb/d above February 2026 levels ^[2].

What to watch

• Front spreads. A flatter December–January Brent spread would suggest that the prompt premium is easing ^[6,7].
• OVX. A sustained fall back towards 2025 levels would point to calmer expectations ^[10].
• Murban against Brent. A rising premium for Hormuz-free barrels would signal renewed concern over bypass routes ^[12].
• EIA and bank revisions. The EIA's next outlook is due on 10 November ^[19].
