Brent vs WTI vs Dubai/Oman — How the Oil Price Benchmarks Work

What is an oil price benchmark?

When traders talk about Brent vs WTI, they are comparing two benchmarks: widely traded, transparently assessed crude prices against which other oil is valued. Physical cargoes are rarely sold at a fixed price. Instead, contracts use a formula in which the cargo's price equals a benchmark price plus or minus a differential for quality, location and timing ^[1]. The three main benchmark families are Brent, West Texas Intermediate (WTI) and Dubai/Oman ^[1]. Brent is the most widely used: Reuters has reported that it prices more than half of the world's physical crude trades ^[4].

Each benchmark has two layers: a physical price, assessed by a price reporting agency (PRA) such as S&P Global Platts or set by exchange delivery, and a layer of futures and other derivatives used for hedging ^[1]. The layers are linked but not identical, and in 2026 the gap between them became unusually large.

How is Dated Brent assessed, and how do Brent futures settle?

Dated Brent is S&P Global's assessment of the price of physical, light North Sea crude cargoes that have been assigned specific loading dates ^[2]. Its main features are:

• Six grades. Brent (Brent/Ninian Blend), Forties, Oseberg, Ekofisk, Troll and WTI Midland, together more than 2.5 million barrels a day (b/d) of production. WTI Midland, included from June 2023 deliveries, is the first grade from outside the North Sea ^[2,3].
• The most competitive grade sets the price. Oseberg, Ekofisk and Troll are adjusted with quality premiums ^[2,3].
• A forward window. Since 2015 the assessment has reflected cargoes loading from 10 days to a full month ahead, at 16:30 London time, based on bids, offers and trades in the Platts Market on Close (MOC) process ^[2].
• An FOB basis. Dated Brent is a free on board (FOB) North Sea value. WTI Midland trades on a cost, insurance and freight (CIF) Rotterdam basis and is netted back to FOB using a freight adjustment. The standard cargo is 700,000 barrels ^[3].

The "Brent price" quoted in the news is usually the front-month ICE Brent futures contract. Each contract covers 1,000 barrels, and trading stops on the last business day of the second month before the contract month, so December expires at the end of October ^[5]. Positions can be converted into physical cargoes through an exchange of futures for physical (EFP), or cash-settled against the ICE Brent Index ^[5]. The index averages five snapshots of trading in the physical forward market for full 700,000-barrel cargoes on expiry day ^[6]. Dated Brent, by contrast, prices prompt cargoes, so the two can diverge sharply when supply is tight.

How does WTI work, and why does Cushing matter?

WTI's benchmark is the New York Mercantile Exchange (NYMEX) Light Sweet Crude Oil futures contract, run by CME Group. Unlike ICE Brent, it is physically delivered. Each contract is 1,000 barrels, delivered FOB at any pipeline or storage facility in Cushing, Oklahoma, with pipeline access to Enterprise's Cushing storage, during the delivery month ^[7]. Trading ends three business days before the 25th calendar day of the preceding month. Delivered crude must have a gravity of 37 to 42 degrees API and sulphur of 0.42% or less ^[7].

Because delivery happens at an inland hub, WTI reflects US pipeline and storage conditions. Research published by the US Energy Information Administration (EIA) notes that WTI and Brent historically traded within $1–2 of each other, with WTI usually higher because it was regarded as slightly better quality. WTI then traded at large discounts, sporadically in 2008–09 and persistently in 2011–12; the research links the earlier episode to transport bottlenecks and a glut of crude at Cushing ^[8].

US light sweet crude also reaches world markets as WTI Midland, exported from Gulf Coast terminals. Platts includes cargoes from pre-approved terminals in Dated Brent ^[3], so US crude competes directly inside the Brent benchmark.

What are the Dubai and Oman benchmarks?

Gulf producers such as Saudi Arabia price crude sold to Asia against the average of Dubai and Oman ^[1]. Platts Dubai is assessed from trade in "partials", part-cargoes traded in the MOC process that can converge into a physical cargo, for which the seller nominates a deliverable grade ^[9,10]. Before March 2026 these were Dubai, Upper Zakum, Al-Shaheen, Murban and Oman ^[9,10,11]. Alongside medium sour grades, the basket includes Murban, whose quality adjustment Platts made two-way from 2 January 2026 ^[11,12]. Oilprice.com reports that the benchmark was used to price around 18 million b/d ^[11].

The Gulf Mercantile Exchange (GME), called the Dubai Mercantile Exchange until 2024, lists the Oman crude futures contract launched in 2007. GME describes it as the world's largest physically delivered crude contract. Oman prices its exports to Asia off the exchange, and Dubai adopted the contract for its own crude in 2009 ^[13].

ICE Futures Abu Dhabi (IFAD) lists Murban futures, physically delivered FOB at the Abu Dhabi National Oil Company's (ADNOC) Fujairah terminal ^[14]. In 2021 ADNOC began setting its Murban official selling price (OSP) from the monthly average of IFAD Murban futures, pricing its other grades as differentials to Murban ^[15]. Murban from Fujairah and Oman both load outside the Strait of Hormuz ^[10], which became critical in 2026.

Brent vs WTI vs Dubai: what is the difference?

Three factors explain the difference between Brent, WTI and Dubai prices.

Quality. Crude is differentiated by API gravity, acidity and sulphur, which affect refining yields ^[8]. Brent and WTI are light sweet crudes ^[2,7], while the Dubai basket includes medium sour grades ^[11]. S&P Global calls the Brent-Dubai exchange of futures for swaps (EFS) "a key indicator of the spread between light, sweet and heavy, sour crudes" ^[16].

Location and freight. WTI futures are priced inland at Cushing, Dated Brent FOB in northwest Europe, and Dubai and Oman at Gulf-region terminals. When tanker routes lengthen, freight and insurance costs rise, which one analyst quoted by Rigzone says inflates waterborne Brent relative to WTI ^[18].

Timing. Dated Brent prices cargoes loading within about a month; futures price later months. In a tight market, prompt crude can trade well above futures ^[20].

Typical spreads. In a stable market the Brent-Dubai EFS sits at about $1.50–2.00/bbl ^[17]. A wider EFS makes Dubai-linked crude more attractive to Asian refiners than Brent-linked crude ^[16]. For Brent vs WTI, the EIA's September forecasts imply a WTI discount averaging about $6.40/bbl in 2026 and about $4/bbl in 2027 ^[18].

How did 2026 change the benchmark spreads?

The conflict that began with strikes on Iran on 28 February tested every benchmark. On 2 March Platts suspended nominations of grades that must transit the Strait of Hormuz: Dubai, Upper Zakum, Al-Shaheen and Murban loading from Jebel Dhanna ^[9]. By 20 March only Murban and Oman could be declared, and Platts stopped assessing the Murban adjustment below zero "to maximize the amount of deliverable crude in the Dubai benchmark" ^[10]. Oilprice.com estimated that supply in the pricing basket fell by roughly 40% ^[11]. In March, Reuters reported Middle East crude prices at record highs, with IFAD Murban futures about $40/bbl below Dubai ^[19].

The Brent-Dubai EFS swung from below $2/bbl before the crisis to above $6 on 3 March, its widest since 2022, and averaged $9.12 in March. In June and July it ranged from about $3.05 to $16.25 ^[17].

Brent's own layers also split apart. North Sea Dated was trading around $134/bbl in mid-October, against about $107/bbl for Brent futures, with some other North Sea grades at up to $160/bbl ^[20]. In late September analysts cited a WTI discount to Brent of $12–14/bbl, the widest since early May, before it narrowed towards $7–8 in early October ^[18].

What to watch

Three signals will show whether the benchmarks are normalising. First, Dubai deliverability: Platts has sought feedback on how its methodology should change if Hormuz traffic resumes or the conflict escalates ^[10]. Second, the gap between Dated Brent and ICE Brent futures, which matters for any cargo priced on Dated but hedged with futures ^[20]. Third, the Brent-Dubai EFS, which trades at about $1.50–2.00/bbl in a stable market ^[17]. The practical lesson is to check exactly which benchmark, assessment and pricing window a contract uses: in 2026 that choice was worth tens of dollars a barrel.
