Refining margin outlook for 4Q15
In 4Q15, Western Refining’s refining segment earnings, which depend on refining margins, will likely be stressed. The key factor that impacts Western Refining’s GRM is refined product cracks. In 4Q15, gasoline cracks narrowed as a result of falling gasoline prices compared to 3Q15. The prices fell due to a huge pile-up of gasoline stocks in the US in 4Q15. This will likely weaken refiners’ GRMs in 4Q15.
A point in case is the broader market US Gulf Coast West Texas Intermediate 321 crack spread. It’s the refining market indicator. It fell in 4Q15. The crack spread averaged $16 per barrel in 3Q15. It fell to $9 per barrel in 4Q15.
