Key takeaway

Argus assessed a record Med diesel crack, nearly $6 above ARA and $33.50 a tonne clear of Northwest Europe.

Argus Media assessed West Mediterranean diesel cracks at $91.67 a barrel on Thursday 30 July, after a peak near $95 on Wednesday 29 July, with the ARA fob crack at $85.86 and the Med-to-northwest-Europe premium at $33.50 a tonne, a three-month high⁠1. A crack is the refining margin between a product and the crude it is made from, quoted here against dated Brent. Argus is one of the independent price-reporting agencies whose published assessments settle physical European gasoil contracts, which makes this a contracted number rather than a screen quote.

The print clears $60.17, the record this desk logged on 8 July, by more than $30, and it carries the same move further than the $80 US diesel crack over WTI reported on 9 July. ARA, the Amsterdam-Rotterdam-Antwerp barge and storage hub that prices Northwest Europe, sits close to $6 a barrel below the Med assessment. Two European refining regions running on the same crude complex do not normally separate by that much, and the $33.50 premium, roughly $4.50 a barrel on gasoil, is where the divergence shows up in a tonne-quoted market.

The separation points at the corridor rather than at the refineries. Mediterranean refiners lean far harder on Red Sea supply routes than their northwest European counterparts do, so a disruption on that corridor reaches Lavera and Augusta before it reaches Rotterdam. Argus attributes the widening to that supply tightening rather than to demand⁠2. A product trading desk should read this as meaning Med-versus-ARA, not the outright crack, is now carrying the geography risk, and the fob-versus-delivered decision on a Med cargo has become a view on a shipping route.

Deep Analysis

In plain English

A 'crack' is the price gap between crude oil and the diesel refined from it, and it is really a measure of how scarce diesel is relative to crude. Argus, an independent firm that assesses these prices daily, found the West Mediterranean gap had reached $91.67 a barrel, more than $30 above the previous record set less than a month earlier. That is one of the clearest signs yet that Europe has too little diesel and is having to pay a steep premium to secure it, distinct from the ups and downs of the crude oil price itself.

Deep Analysis
Root Causes

Diesel cracks widen when refiners cannot bring enough product to market fast enough to meet demand, and Europe's diesel deficit is structural: the region imports roughly a third of what it burns, and every major backfill route (Saudi Red Sea, Russian) is now constrained at once.

A record crack this early in the disruption suggests the market has not yet found a substitute supply route; historically the crack keeps climbing until either demand destroys itself (refiners and hauliers cut consumption) or a new supply route opens, whichever comes first.

What could happen next?
  • Consequence

    A crack this wide typically pulls in diesel cargoes from further afield (Asia, the US Gulf Coast) within weeks, which would cap further records but not necessarily bring the crack back down quickly.

Causes and effects
This Event
Med diesel crack assessed at $91.67
The assessment is the number Mediterranean term diesel deals price off, so a record here lands in refiners' contracted margins rather than only on a screen.
Different Perspectives
United States (Joint Maritime Information Center)
United States (Joint Maritime Information Center)
The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.
Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.
Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
