What it means
Brent Blend started as the output of a single North Sea field and has grown into a basket of several light, low-sulphur crude streams. Light and sweet means it is relatively easy to refine into petrol and diesel, which is why it commands a premium over heavier, higher-sulphur grades.
The physical volumes involved are modest, but the pricing influence is global. A benchmark works because it is liquid, transparent and shipped by sea, so buyers anywhere can compare it.
A large majority of internationally traded crude is priced by reference to Brent, either directly or through a contract formula. Most of the rest is priced off West Texas Intermediate in the Americas or off Middle Eastern benchmarks in Asia.
In practice there are several Brent prices and it pays to know which one is being quoted. Dated Brent refers to a physical cargo with a loading date assigned, Brent futures settle on an exchange for a given future month, and forward Brent trades for a month with no date yet fixed.
Contracts specify one of them, plus a differential that reflects the actual grade and delivery point. For a business that is not an oil trader, Brent still shows up in the accounts.
Airlines, hauliers, chemical producers and shipping lines hedge fuel using Brent-linked contracts, and long-term supply agreements often index prices to the Brent average over a quoted period. A budget built on a fixed fuel price without a hedge is really a bet on Brent.
The benchmark is not static. Declining North Sea production has forced the basket to be widened over time, including the addition of a US crude stream delivered into Europe, so that enough cargoes exist to keep the price honest.
Anyone holding a long-dated contract indexed to Brent should check how the agreement handles changes to the basket.
In practice
Real-world examples.
Example
An airline expecting to burn 3,000,000 barrels of jet fuel next year buys Brent-linked call options struck at $90 a barrel. When Brent averages $96, the $6 a barrel payout returns 3,000,000 x $6 = $18,000,000, offsetting most of the extra fuel cost.
Example
A West African producer sells cargoes at dated Brent plus $1.20 a barrel because its crude is slightly lighter and lower in sulphur than the benchmark. On a 950,000 barrel cargo with Brent at $80.00, that differential is worth 950,000 x $1.20 = $1,140,000 more than a flat Brent price.
Example
A chemicals producer signs a three-year feedstock contract indexed to the monthly average of dated Brent. Its budget assumes $75 a barrel, so the finance director models the profit impact at $65 and at $95 and presents both scenarios to the board rather than a single number.
Formula
Calculation
Formula: cargo value = barrels x (Brent benchmark price + quality differential). Brent-WTI spread = Brent price - WTI price.
Worked example: A refiner buys a 600,000 barrel cargo of a crude grade that trades at a differential of -$0.50 a barrel against dated Brent. Dated Brent settles at $82.00, so the cargo price is $82.00 - $0.50 = $81.50 a barrel and the invoice comes to 600,000 x $81.50 = $48,900,000.
On the same day West Texas Intermediate settles at $78.50, so the Brent-WTI spread is $82.00 - $78.50 = $3.50 a barrel. A US exporter shipping 600,000 barrels of WTI-linked crude into Europe therefore captures 600,000 x $3.50 = $2,100,000 of headline advantage.
Freight is the offset. At $2.20 a barrel the voyage costs 600,000 x $2.20 = $1,320,000, leaving a net gain of $2,100,000 - $1,320,000 = $780,000. When the spread narrows below the freight cost, the cargoes stop moving, which is why traders watch the spread and the freight rate together.Case study
Seen in the real world.
Kestrel Aviation Holdings is an illustrative, fictional regional airline that budgets fuel at $85 a barrel of Brent-equivalent cost and expects to consume 1,200,000 barrels next year. Its board asked what a $10 move in Brent would do to profit.
The answer was 1,200,000 x $10 = $12,000,000 in either direction, against a budgeted operating profit of $20,000,000. Kestrel therefore hedged 60% of its consumption, or 1,200,000 x 60% = 720,000 barrels, using Brent swaps. That left 1,200,000 - 720,000 = 480,000 barrels exposed, cutting the effect of an adverse $10 move to 480,000 x $10 = $4,800,000.
The illustrative point is that Brent is not just a headline number for oil companies. For any business with meaningful fuel or feedstock exposure the benchmark sets the size of a risk that can easily exceed a whole year's profit, and quantifying it is the first step to deciding how much of it to keep.
Watch out
Common mistakes.
- Thinking Brent is a single oil field, when it is a basket of several North Sea streams that has been widened over time.
- Quoting a Brent price without saying whether it is dated, forward or futures, since the three can differ by a meaningful margin.
- Assuming a fuel budget indexed to Brent is hedged, when indexing simply passes the price movement straight through to the buyer.
Questions
People also ask.
Why does Brent price more of the world's oil than WTI?
Because it is waterborne and easily shipped anywhere, whereas WTI is priced inland in the United States and reflects local conditions.
What is the Brent-WTI spread used for?
It signals the economics of shipping US crude to Europe or Asia and is traded in its own right by refiners and speculators.
Does Brent set the price at the petrol pump?
Only indirectly, because crude is one input alongside refining margins, distribution costs, retailer margin and fuel duty.
