LONDON, July 16 — Brent Crude, the global oil benchmark that underpins approximately 80% of the world’s petroleum trade, has a technical reality most market watchers rarely pause to examine. It began as a single field—the Brent oilfield in the North Sea, first tapped in 1976—and has since evolved into a complex financial instrument and a sprawling blend of crudes from multiple continents.
The detail that matters for anyone tracking jet fuel prices, airline hedging strategies, or the broader energy economy is this: Brent is no longer just North Sea oil. The classification itself is precise.
Brent Crude refers to sweet crude oil and light crude oil—meaning low density and low sulfur content, characteristics that make it relatively easy and cheap to refine into high-value products like gasoline and jet fuel. In finance, the term identifies a futures contract traded on the Intercontinental Exchange, or ICE. That contract is the reference standard for setting petroleum prices across the Atlantic basin and beyond.
The BFOET Evolution
Under the hood, the benchmark has undergone significant structural changes as North Sea production has declined. In 2002, ICE added blends from the Forties and Oseberg oil fields to the basket. Ekofisk followed in 2007, and Troll in 2018.
The resulting basket is known as the BFOET Quotation, each letter representing one of the constituent fields. The most consequential shift came in 2021, when petroleum production from the original Brent field itself ended.
Rather than retire the benchmark, ICE expanded the classification further. Then, in 2023, the basket added petroleum from Midland, Texas—a move that tied a North Sea legacy benchmark directly to Permian Basin output.
Why It Matters for Airlines
The Brent blend directly influences jet fuel pricing, because jet fuel is a refined petroleum product and its cost represents a major operating expense for airlines. Fluctuations in Brent crude prices impact airline profitability, ticket prices, and hedging strategies. When the benchmark moves, the effects ripple through balance sheets and budget carrier pricing models.
Airlines do not simply pay whatever the spot price demands on a given day. They hedge—locking in fuel costs months or even years ahead using futures contracts tied to benchmarks like Brent.
A trader or CFO watching the BFOET basket is watching a proxy for their own cost base. The technical reality is that a barrel of light, sweet crude from Texas, blended with North Sea grades and traded on an exchange in London, sets the price for fuel burned from Heathrow to Houston.
Two Benchmarks, One Atlantic
Brent Crude is one of two commercial benchmarks for setting petroleum prices globally. The other is West Texas Intermediate, or WTI, which primarily prices crude produced in and delivered to the United States. The two benchmarks diverge and converge based on pipelines, refinery configurations, and storage levels.
But for international crude trade, especially Atlantic-basin grades, Brent remains the reference. The London Brent, as it is sometimes called, or simply Brent petroleum, has become a catch-all term that masks its increasingly complex composition.
What started as a single field in the North Sea now includes crude from Norway, the UK, and the United States.
