Feature: Brent complex evolves to fully reflect Atlantic Basin light sweet crude market dynamics

Banner Image

The Brent market has undergone a long-awaited evolution this year, with the addition of WTI Midland crude meaning that the complex more accurately than ever captures the fundamentals and pricing of light sweet crude oil in the Atlantic Basin.

Since the lifting of the US crude export ban in 2015, WTI Midland has played an increasingly influential role in the pricing of crude being delivered into Europe. North Sea grades such as Forties and Ekofisk, Mediterranean grades such as CPC Blend and Azeri Light and West African grades such as Qua Iboe and Bonny Light have all had to adapt to over one million barrels of light sweet US crude being delivered each day into Europe.

In the period since US crude became accessible to the global market, refiners across Europe have benefitted from the increased choice of crude and have adjusted refining slates accordingly and optimized between WTI Midland and its Atlantic Basin competitors. Prior to May 2023 the value of grades within Dated Brent were already being impacted, albeit in a somewhat opaque way, by the steady flow of WTI Midland into Europe. Now the pricing of this established trade flow has been illuminated and made transparent by its incorporation into the Brent complex.


WTI Midland's role in the price of Dated Brent has been much discussed since the grade's introduction for June 2023 cargoes. An examination of assessment data since May 2 clearly demonstrates that WTI Midland has been influential, but not overwhelming.

The Platts Dated Brent assessment is defined by the most competitive, or cheapest, grade every day. S&P Global Commodity Insights gives each day in the 10-month ahead assessment range a value for each grade. The final assessment is reflective of any number of the six grades, depending on what is the most competitive valued grade on each day, so a single assessment could be representative of 40% Midland, 40% Forties and 20% Brent, for example.

In June Midland was typically the most competitive grade, while in August Forties has most often helped define the benchmark.


The addition of WTI Midland to Dated Brent has facilitated a large increase in the amount of deliverable crude into Dated Brent, and this has been reflected in a sharp uptick in activity in the Platts Market on Close assessment process. Since May through July, a diverse group of oil majors and traders collectively traded 40 cargoes of WTI Midland comprising a total volume of 28 million barrels of crude.

At 16.8 million barrels, July 2023 was the largest month for overall Dated Brent cargo trades since January 2021, and the joint-fourth busiest month on record.

Performance tracking

As part of an ongoing commitment to upholding the highest standards of integrity and transparency in its Platts Dated Brent MOC process, S&P Global monitored performance on the 17 WTI Midland CIF Rotterdam trades published in the MOC process during the first two months of May and June. This post-deal tracking enables S&P Global to determine the actual performance of the participants in the trades and the validity of their inputs.

As part of this, S&P Global reviewed various aspects of performance, including timeliness of nominations and eventual delivery, as well as published parameters of the trades, including quality and volume.

Of the 17 trades tracked, two were booked out upon mutual agreement, while all others were physically delivered to buyers. Although all 17 published WTI Midland trades were fully performed upon, two of the cargoes initially provided did not meet the parameters of the published trades. In both cases, full performance was eventually reached, with the entities involved coming to bilateral agreement on final terms.

Physical conditions regarding logistics -- which are beyond the control of the seller or buyer -- may result in lateness, quality issues or conditions seen as a deviation from the original wording in the reported trade, for example late delivery/loading. As per methodology, if a transaction becomes difficult, the party causing the issue must seek resolution including alternative loadings, qualities, dates or book outs.

S&P Global also reviewed the quality of all cargoes, and the table within the graphic shows the minimum and maximum values of some key quality metrics. Notably, only one cargo out of all tracked exceeded the WTI Midland specification that S&P Global reflects in its assessments. However, all cargoes that were eventually delivered to buyers fully met the specification.

Dangote refinery pursues long-term US crude supply despite domestic overhang

US crude oil could remain a staple feedstock for Nigeria's Dangote refinery in the medium term, as the plant has courted another year's worth of WTI Midland supply despite ample availability for domestic grades. In a tender set to close May 21, Dangote has sought to lock in 2 million barrels per month of WTI Midland crude oil from July 2024, in a proposed 12-month offtake agreement, according to terms seen by S&P Global Commodity Insights. While the refinery is geared towards processing Nigerian grades, WTI crude has represented around a third of its crude imports since December, according to S&P Global Commodities at Sea data, with the feedstock processed in some of the plant's first test runs on the year. According to CAS, the refinery took delivery of 11 WTI cargoes, or 9 million barrels, between February and May, contrasting with around 18 million barrels of Nigerian crude deliveries. Now, the move to secure a longer-term offtake agreement signals a commitment by the refinery to more permanently diversify its crude sources, coinciding with a period of extreme demand weakness for Nigerian supply. "It's a little surprising that they are seeking term WTI at this stage," said one West African crude trader, noting demand weakness that pushed Nigeria's flagship Bonny Light crude to a discount to Dated Brent for the first time since November on May. 17. According to Platts assessments Bonny Light FOB Nigeria premiums flipped to a discount of 5 cents/b to Dated Brent on May 17, down from a premium of 70 cents/b the previous week. Platts is a part of S&P Global Commodity Insights. "Domestically of course there will be dismay that they are turning to non-Nigerian crude and hence not supporting the country's own production," he said, pointing to pressure at home for the refinery's operations to support the ailing crude market. Cost advantage, supply certainty Yet so long as international grades remain competitive to domestic supply, the refinery will continue to optimize accordingly. "My assumption is that they see WTI Midland as likely always being a competitive valued barrel, even vs FOB Nigerian and at least in this stage of the refinery's startup to full capacity," said the trader. Nigeria's state-run Nigerian National Petroleum Company (NNPC), also 20% equity holder in the project, has been widely expected to supply the bulk of Dangote's crude demands, selling to the refinery in USD due to its location in the Lekki free zone. Yet while the producer may be able to fulfil the refinery's crude requirements during its ramp-up, it could struggle to exclusively fulfil demand from Dangote at full utilization, while leaving the refiner exposed to supply disruptions. To date, the refinery has only taken delivery of Nigerian and US crude grades, but it could increasingly seek alternative term contracts with alternative supply sources as it scales production, traders have speculated. "It's not unexpected that they would seek to cover base requirements for the refinery through term business in the same way for example some of Indian refiners do with Middle Eastern crude," said one source. Racing to ramp-up As the refinery's management has continued to signal ambitious timelines for delivery of its first gasoline supplies to the domestic market, considerations around supporting crude revenues could also take a backseat. Speaking at the Africa CEO Forum Annual Summit in Kigali, refinery owner Aliko Dangote announced that Nigeria would have no need to import "a drop" of gasoline from June, pledging that new supply from the refinery would end a historic reliance on the fuel grade in the coming weeks, according to reports from local media. With the government expected to be partially subsidizing costs for continued gasoline exports, the first supplies from the refiner would ease pressure on the national budget, though S&P analysts have said the first gasoline supplies are unlikely to arrive before Q3 2024. "For now the key concern for Abuja is whether the refinery is able to produce petrol, and therefore how soon they can actually get on with subsidy removal that relieves massive pressure on public finances. So while that's the first priority, I suspect they won't mind so much where the crude comes from," said Clementine Wallop, director for sub-Saharan Africa at political risk consultancy Horizon Engage. At full capacity, the 650,000 b/d refinery is expected to yield some 327,000 b/d of gasoline, however timelines and volumes to be allocated domestically remain uncertain. Representatives for Dangote were not available to comment on crude supply plans for the site.
