Direct Answer
Crack spread trading trades the refining margin, the difference between the price of refined products (gasoline and heating oil or diesel) and the price of crude oil, by buying product futures and selling crude futures in a ratio such as 3:2:1 (three crude, two gasoline, one heating oil) or the reverse, so the position profits from changes in refiners' margins rather than in oil prices. It tends to work for traders with a view on refining capacity and product demand, since the margin has strong seasonality and responds to refinery outages in ways that crude alone does not. Three futures legs with separate expiries and gallons-to-barrels conversions; an error in the ratio or the roll turns a spread into an outright bet.

How Does Crack Spread Trading Work?
Crack spread trading trades the refining margin, the difference between the price of refined products (gasoline and heating oil or diesel) and the price of crude oil, by buying product futures and selling crude futures in a ratio such as 3:2:1 (three crude, two gasoline, one heating oil) or the reverse, so the position profits from changes in refiners' margins rather than in oil prices.
The rules:
- Compute the crack as product price minus crude price per barrel, converting gasoline and heating oil from gallons (42 gallons per barrel)
- Use a standard ratio such as 3:2:1 or a single-product 1:1 crack, matched to the refinery output being modeled
- Enter when the crack is far from its seasonal norm: cracks tend to widen into the summer driving season and narrow after
- Watch refinery utilization, maintenance schedules and product inventories, which drive the margin
Worked example. With gasoline at 2.40 a gallon, heating oil at 2.60 and crude at 80.00 a barrel, the 3:2:1 crack spread is about $23.60 per barrel of crude, the refining margin the position tracks. The inputs are illustrative numbers, not market data.
When it tends to work. It tends to work for traders with a view on refining capacity and product demand, since the margin has strong seasonality and responds to refinery outages in ways that crude alone does not.
When it fails. It fails when crude and products move in ways the ratio does not capture, such as a gasoline-specific demand shock, and the multi-leg position has execution and roll complexity.
Main risk. Three futures legs with separate expiries and gallons-to-barrels conversions; an error in the ratio or the roll turns a spread into an outright bet.
