Is refining supply still tight?
3-2-1 crack spread (WTI–Gulf Coast spot) · Weekly
History: 92 observations · Local history available
Calculated from same-week spot averages: (2 × Gulf Coast gasoline + Gulf Coast ultra-low sulfur diesel) × 42 ÷ 3 − Cushing WTI. Product prices are converted from USD/gal to USD/bbl. This reference spread is neither a futures spread nor realized refinery profit; location basis, transport and other refining costs are not deducted.
