The crude market has adjusted to the presence of US WTI in the Dated basket, but the past year has revealed some hiccups, suggesting more changes will be needed to the benchmark's structure.
WTI has been a part of Dated for more than a year, in which time it has bought much-needed liquidity to a shrinking amount of physical crude underpinning the benchmark, and has encouraged a return of some old, long-absent market participants and the entry of a few new ones. WTI has introduced more transparency to Dated, making it much more easily accessible.
While some traders feared the grade would arrest any volatility, which is necessary for trading companies to thrive, this has not happened. Instead, WTI has effectively tied the European market to the US one, with European Ice Brent futures following WTI Nymex futures very closely.
But recent months have exposed some flaws, suggesting some more changes to the benchmark are needed.
European refiners run as much as 4.5mn b/d of light sweet crude, Vortexa data show. Dated was designed to represent the price moves of this large market via a few crudes produced, and mostly consumed, in the region. But production of several component grades have shrunk because of natural decline at North Sea fields. Production of Brent, the benchmark's namesake grade, has fallen from above 400,000 b/d in 2001 to just 38,000 b/d this year. Forties' exports dropped from more than 600,000 b/d to 175,000 b/d in the same time. Therefore it seemed fair when Dated was set by WTI nearly half of the time, as it is the single largest crude that European refiners buy, accounting for around 14pc of all their supplies.
The situation reversed in the last weeks of 2024. WTI has not set Dated since 11 October, with that duty mostly shared between Oseberg, Ekofisk and Troll. But values of these grades — especially Oseberg and Troll — are rather theoretical, due to low liquidity of just 2-5 cargoes a month. It is not uncommon to see bids for those grades in the window, when the scarce supplies loading on the dates covered by bids are already placed.
The same applies to Brent, for which loadings range between just 1-2 cargoes every month. WTI and Forties have greater liquidity, allowing them to be more representative of Europe's light sweet market, but their recent marginal role in setting the benchmark price raises a question if grades like Brent, Oseberg and Troll need to be in the basket at all.
QPs an almighty relic of the past
It might feel counterintuitive that smaller and more expensive grades affect the price of Dated — which is set by the cheapest grade in the basket.
But Oseberg, Ekofisk and Troll, which are typically more expensive on a fob basis than is WTI on a delivered-Europe basis, are adjusted by quality premiums (QPs) for benchmarking purposes. QPs are calculated at 60pc of the difference between each grade and the most competitive of the six benchmark grades in the second month prior to the month of loading.
The mechanism was made for a basket of crudes that originate in the North Sea and trade on a fob basis. Inclusion of WTI, which in turn is adjusted by intra-European freight to make it a fob price in the North Sea, has widened QPs for the three grades.
With price spreads between pricier and cheaper benchmark grades increasingly dependent on volumes of WTI coming to Europe, such an adjustment does not seem to serve its purpose anymore.
