3-2-1 Crack Spread

The 3-2-1 Crack Spread approximates the value of crude oil inputs and product outputs – in effect an indicator of refinery profitability. The 3-2-1 Crack spread approximates a theoretical refinery crude yield that produces two barrels of gasoline and one barrel of diesel for every three barrels of crude input. In other words, the simplified refinery yield implied by this calculation is two-thirds gasoline, one-third diesel. It is calculated in $/bbl.
