Gasoline Crack Spread

The gasoline crack spread represents the price difference between crude oil and gasoline, and it is commonly used as a proxy for refinery margins. It reflects the gross profit a refiner might earn by purchasing crude oil and converting it into gasoline, before accounting for operating costs, logistics, and other refined products. Crack spreads are expressed as ratios, such as a 3:2:1 crack, indicating the assumed output mix of refined products.

Traders and refiners use gasoline crack spreads to hedge refining exposure. For example, a refiner concerned about declining margins might sell gasoline crack spreads to lock in profitability. Conversely, a trader anticipating strong driving-season demand may buy gasoline crack spreads to profit from rising gasoline prices relative to crude.

Crack spreads are influenced by seasonal demand patterns, refinery outages, environmental fuel specifications, and crude quality. In the summer, gasoline crack spreads often widen due to increased driving demand. Because of their sensitivity to real-world consumption, gasoline crack spreads are closely monitored as indicators of consumer activity and fuel market tightness.
