What Is Dated Brent?

The physical spot benchmark that prices most of the world's traded crude — and how it differs from the futures price on the charts

Dated Brent is the assessed price of a physical cargo of North Sea crude oil that has been assigned — or "dated" — a specific loading-date window at a North Sea terminal. It is a daily price assessment published by S&P Global Commodity Insights (the business historically known as Platts), produced from observed bids, offers, and trades in the physical North Sea market. Despite its name, Dated Brent is no longer a price for a single field's output; it is the value of the cheapest deliverable cargo from a basket of several North Sea grades, and since 2023 from a designated stream of U.S. crude delivered into Northwest Europe. That assessed number sits at the center of the global oil-pricing system: the price formulas that govern a large share of internationally traded crude — by common estimates roughly two-thirds of the world's physically traded barrels — reference Dated Brent directly or indirectly.

Dated Brent must be distinguished carefully from the headline "Brent" figure most people see quoted in the news and on price charts. That number is ordinarily the front-month ICE Brent futures contract — a financially settled, exchange-traded instrument. Dated Brent, by contrast, is a physical spot assessment for cargoes loading in the near future. The two are linked through a chain of derivatives and through the futures' cash-settlement index, but they are conceptually and operationally separate. This page explains what "dated" means, how the assessment is constructed, the basket of grades that underpins it, the forward and derivative markets that surround it, and why it remains the reference for so much of world trade.

What "Dated" Actually Means

From forward to dated. North Sea crude is sold first in a forward market — cargoes traded for a generic month of loading before a precise three-day loading range has been allocated. This is the "cash BFOE" or forward Brent market, where a contract is for, say, a cargo loading sometime in a stated calendar month. Once the terminal operator nominates a specific loading-date window to a particular cargo (under the relevant loading programmes and nomination rules), that cargo becomes "dated" — it now has a known, narrow loading range.

The Dated Brent assessment captures the value of these wet, near-term physical cargoes. Each business day the assessment references cargoes loading within a defined forward window from the assessment date — the window has been widened over the years to keep enough cargoes in scope as North Sea liquidity evolved. Because a dated cargo has a fixed loading slot, its value reflects current supply and demand for prompt physical barrels rather than the smoother expectations embedded in futures.

How the Assessment Is Made

Dated Brent is assessed during the Platts Market-on-Close (MOC) window, a structured period late in the London trading day during which accredited participants submit bids and offers and report trades in standardized form. Editorial staff observe all activity in the window and use it, together with broader market context, to construct and publish the daily assessment shortly after the window closes.

The cargo standard is a full North Sea cargo (commonly 600,000 barrels) of a deliverable grade. Because several grades can be delivered, the assessment is built around the value of the most competitive cargo — the cheapest grade on a quality-adjusted basis that a seller could deliver. Quality differences between grades are normalized using published quality premia, so that the assessment reflects a consistent benchmark value rather than the idiosyncrasies of whichever stream happens to be cheapest on a given day.

The BFOET Basket

Several streams, one benchmark. Dated Brent is underpinned by a basket of deliverable grades rather than a single crude. The basket — known by the acronym BFOET — comprises Brent, Forties, Oseberg, Ekofisk, and Troll, the principal light, sweet-to-medium-sweet streams of the British and Norwegian North Sea. The use of a basket is deliberate: pooling multiple grades keeps enough cargoes and enough sellers in the deliverable pool to sustain a liquid, manipulation-resistant benchmark even as individual fields decline.

In 2023 the deliverable pool was widened further with the addition of WTI Midland delivered into Northwest Europe. U.S. light sweet crude had been arriving in large volumes and was of comparable quality, so including it added a deep new source of deliverable barrels and reinforced the benchmark's long-term liquidity. The principle remains unchanged: whichever grade is most competitive on a quality- and freight-adjusted basis sets Dated Brent.

The Forward "Cash BFOE" Market

Sitting just upstream of Dated is the forward North Sea market, generally called cash BFOE. Here participants trade unallocated cargoes for a named loading month — for example "first-half" or full-month cargoes — before specific dates are assigned. This forward market is where much of the price discovery for physical North Sea crude takes place, and it is the venue from which cargoes graduate into the dated pool once they are allocated loading windows.

The relationship between the forward cash market and Dated is important for traders. The forward price reflects the value of a still-unallocated cargo, while Dated reflects a cargo with a known prompt loading slot; the spread between them, alongside the broader curve, encodes the market's view of prompt physical tightness or surplus.

The Derivatives Chain Linking Dated to Futures

CFDs and DFLs. Two families of derivatives connect the Dated assessment to the forward and futures markets. Dated-to-frontline-futures swaps, commonly called DFLs, exchange the Dated Brent assessment against the front-line forward or futures price over a period, allowing participants to convert exposure between the physical and paper legs. Contracts-for-difference, or CFDs, are short-dated weekly swaps that trade the spread between Dated Brent and the forward cash BFOE price for specific near-term weeks.

Together these instruments let a refiner, producer, or trader move risk smoothly along the curve — from a financially settled futures position, through the forward cash market, to a specific dated physical cargo. They are also how the broad, liquid futures market transmits price information back into the relatively thin physical assessment, and vice versa. The current front-month futures value that this chain ultimately references can be followed on the live Brent chart.

Dated Brent Versus ICE Brent Futures

The single most common point of confusion is the difference between Dated Brent and ICE Brent futures. ICE Brent futures are standardized, exchange-traded, cash-settled contracts; the front-month contract is the number plotted as "Brent" on most charts. Dated Brent is a daily physical spot assessment for prompt-loading cargoes. The futures contract is in fact cash-settled against the ICE Brent Index, which is derived from the forward cash BFOE market — so the two are tightly coupled, but they are not the same price and can diverge, especially during periods of acute physical tightness or oversupply.

For most pricing purposes the distinction matters greatly. A cargo of West African or Mediterranean crude is typically priced as "Dated Brent plus or minus a differential," not as a futures price. The physical assessment is what flows into those formulas, which is why Dated Brent — not the exchange contract — is described as the benchmark that prices most of the world's crude.

Why Dated Brent Prices the World

Dated Brent's reach comes from history and convenience rather than from North Sea volume, which is modest in global terms. As an early seaborne, freely traded, light sweet crude with a transparent daily assessment, North Sea Brent became the natural reference for Atlantic Basin and many other waterborne grades. Once a benchmark is embedded in thousands of supply contracts and term formulas, it tends to persist, and the basket structure has allowed Dated Brent to keep functioning even as the original fields wound down.

It also anchors cross-regional spreads. The relationship between Brent and Middle East crude is captured in the Brent–Dubai EFS, which traders use to value arbitrage between Atlantic Basin and Asian markets. In this sense Dated Brent is not only a price but a hub through which much of the global crude complex is referenced.

The robustness of this role depends on the assessment remaining transparent and difficult to manipulate, which is why the basket structure and the structured assessment window matter so much. A benchmark that priced trillions of dollars of trade off a single thinly traded grade would be dangerously exposed; a benchmark built on a diverse, quality-adjusted pool of grades observed through a disciplined daily process is far harder to distort. The credibility of Dated Brent — and therefore of everything priced against it — rests on that institutional design as much as on the oil itself.

Dated Brent in One Sentence

Dated Brent is the daily-assessed price of the most competitive physical North Sea (and now WTI Midland) cargo carrying a specific loading-date window, and it serves as the reference price for a large majority of the world's internationally traded crude.
