What does it mean?

The above graph illustrates the US Gulf Coast 3:2:1 crack spread over several days. The 3:2:1 crack spread reflects a theoretical calculation of the difference between the price of two barrels of gasoline and one barrel of distillate fuel, and the cost of three barrels of crude oil where these products are assumed to be produced.

Crack spreads usually rise when crude oil prices (USO) increase by less than product prices, or when product prices fall less than crude oil prices. The latter was the case in the week ended October 23. WTI prices fell 5.6%, while gasoline prices fell 1.8% and diesel prices fell ~2.8%.

Why watch crack spreads?

Crack spreads represent the price difference between refiners’ revenue derived from the sale of finished refined products and refiners’ costs or the price of crude oil (USO). So they’re an important metric that drives refiner profitability and market valuation. This is something investors in refiner stocks should watch.

A wider crack spread increased the profit margins of refiners such as Valero Energy (VLO), Phillips 66 (PSX), Marathon Petroleum (MPC), and Tesoro (TSO). They can purchase raw materials or inputs at a lower rate. Conversely, narrower crack spreads can lower profit margins for refiners. Together, these companies account for ~12% of the Energy Select Sector SPDR ETF (XLE).

The above companies spun off some of their midstream assets to form Valero Energy Partners (VLP), Phillips 66 Partners (PSXP), MPLX (MPLX), and Tesoro Logistics (TLLP). These are all midstream MLPs. A wider crack spread would indirectly benefit these companies. Higher volumes produced by their refining parents in response to lower input costs would mean higher volume to transport. This could boost the MLPs’ revenue. For more on crack spreads, please read Crack Spread 101.
