For a physical distillate buyer, the outright price of crude is only half the story. The more useful signal is the crack spread: the difference between the price of a refined product such as gas oil (diesel) and the crude it is refined from.
Why the crack matters more than the flat price
When the gas oil crack widens, refiners earn more per barrel of diesel produced. That incentivises higher run rates and, eventually, more supply. When it narrows, the opposite happens: refiners trim throughput or shift yield toward other products, and distillate availability tightens.
For buyers in the UAE, East Africa and South Asia, a widening crack usually signals firmer diesel prices ahead and rewards those who have secured supply and storage early. A narrowing crack can open short-term buying windows.
How we use it
Because we hold physical storage and refining access, we watch the crack alongside freight to time cargoes rather than chase the flat price. A few practical rules of thumb:
- Widening crack, firm freight: lock in volume and storage early; delivered prices rarely fall in this environment.
- Narrowing crack, soft freight: consider spot parcels and shorter commitments.
- Crack diverging from Brent: look at regional stock data (Fujairah, Singapore, ARA) before assuming the move is global.
The crack is a refiner's margin, but it is also a buyer's early warning system.
What to ask your supplier
Ask how a quoted price relates to the benchmark, which benchmark it is tied to (ICE gas oil, Platts MOPAG, or a fixed price), and how the premium or discount is justified. A counterparty with physical storage can usually explain their basis clearly, because they live with it every day.
