Diesel crack and Hormuz premium stack

3 min read

US ultra-low-sulphur diesel jumped near $154 a barrel on 8-10 July as Russian loadings collapsed to 234 kbd, a crack answering to lost supply, not war risk.

Key takeaway

Diesel is dear because Russia stopped exporting it, a shortage set to outlast the oil war-scare.

US ultra-low-sulphur diesel jumped to about $154/bbl on 8-10 July, a roughly $80/bbl crack over WTI, according to a single trade wire 1. The crack, a refiner's margin from turning a barrel of crude into diesel, had already blown out in Europe, where it held near $46 in early July , after Novak's full Russian export ban .

Russian barrels, not war risk, drove the fresh leg. Diesel and gasoil loadings ran just 234 kbd for 1-10 July, against a 400 kbd June pace and an ~817 kbd 2025 average, before the formal 31 July ban even bit 2. The loadings data shows a supply loss already happening on the water, which the ban simply formalises.

That separation is the whole trade. The crack premium prices lost Russian supply; the flat-price premium prices Hormuz transit fear. They rest on different clocks and add to each other rather than substituting, which is why the crack held firm through a week the flat price round-tripped. EU Regulation 833/2014 bars the discounted Russian and Iranian barrels from reaching the European pool, so a hedge that assumes the crack and the Hormuz premium deflate together will slip when only one of them fades.

Deep Analysis

In plain English

Diesel is a fuel refined from crude oil, used mainly in trucks, ships and heavy machinery. The 'crack' is the extra price refiners can charge for diesel above the cost of the crude oil that goes into making it, a rough measure of how tight diesel supply is. In early July, US diesel prices jumped to about $154 a barrel, roughly $80 more than the cost of the crude used to make it, a very wide gap. At the same time, Russia's diesel and fuel-oil shipments dropped sharply, to about a third of last year's average pace, even before a formal Russian export ban (announced by deputy prime minister Alexander Novak) takes effect on 31 July.

Deep Analysis
Root Causes

The diesel crack's outsized widening traces to a supply mechanism distinct from the Hormuz risk driving crude: Russian diesel and gasoil loadings fell to 234 kbd for 1-10 July, down from a 400 kbd June pace and roughly 817 kbd across 2025, even before Novak's formal 31 July export ban takes effect , meaning buyers are already losing Russian barrels ahead of the legal deadline.

The European pool has no substitute source, since Regulation 833/2014 already excludes Russian and Iranian diesel from the bloc , so any further loss of Russian volume has nowhere else to draw from within Europe.

What could happen next?
  • Consequence

    The diesel premium is stacking on top of, rather than substituting for, the Hormuz-driven crude risk premium, meaning European and US diesel buyers face two separate cost pressures simultaneously.

  • Risk

    If Russian loadings do not recover once Novak's ban formally binds on 31 July, the diesel crack could widen further from its already elevated 8-10 July level.

Different Perspectives
Indian refiners
Indian refiners
Indian refiners kept lifting discounted Urals as the India/Baltic price split widened past $9-10 a barrel, a gap that only grows as GL X1's Iranian wind-down cuts an alternative discounted grade off the market by 17 July. Cheaper Russian feedstock is being locked in while it lasts.
Chinese refiners
Chinese refiners
Chinese refiners gain leverage as the Urals-Brent discount widens, since Beijing's state buyers already source discounted Russian barrels near the fiscal floor unaffected by Western insurance costs. A wider discount, if it holds past 23 July, lets them lock in cheaper term contracts regardless of the cap's outcome.
US money managers (CFTC-tracked)
US money managers (CFTC-tracked)
Managed money trimmed WTI net length into the rally, positioning that reflects doubt the Hormuz premium survives without freight or war-risk confirmation. The Brent-WTI spread widening almost entirely on the Brent leg supports that scepticism about a broad-based repricing.
OPEC+ (Saudi-led subgroup)
OPEC+ (Saudi-led subgroup)
Saudi Arabia is defending market share through a fourth straight 188kbd August hike even as OPEC's own July MOMR cut 2026 demand growth for the fourth consecutive month. At a $108-111 fiscal breakeven, every added barrel costs Riyadh revenue it cannot recoup, so the hike reads as a positioning signal, not a demand bet.

Greece, backed by Cyprus and Malta, is pushing a three-month cap-freeze compromise against the Commission's freeze to January 2027 ahead of the 23 July vote. Athens' and Valletta's combined tanker registrations mean a shorter review gives their insurers more frequent chances to reprice risk on Russian cargoes.
Russia (Deputy PM Alexander Novak)
Russia (Deputy PM Alexander Novak)
Novak extended the diesel export restriction to producers on 8 July, the first producer-binding curb of the war, protecting the domestic pump price ahead of any refinery repair timeline. Urals still trades below Russia's $59 budget floor even as Brent gained, so the ban trades export revenue for fiscal stability at home.
