With diesel prices soaring and motor gasoline not far behind, the 3:2:1 crack spread popped up to $37/bbl on Friday, the highest it has been all year. That’s very good news for refineries, and it’s even better than it looks if we compare the crack spread to crude oil, which indicates refinery margins relative to the price of crude. In other words, looking at the crack spread as a percentage of WTI.
The left graph shows the annual crack spread to crude ratio since 2007. The ratio has been on a steady march higher for years, with the average spiking higher in 2022 and reaching a record annualized level so far this year. And in the past week, with the crack spread moving up and crude prices relatively stable, the ratio increased to 59%, the highest in 2023 except for three days in March.
Bottom line. U.S. refineries are capturing a historically high portion of the value of crude oil.
