The differential between Permian/Midland WTI crude oil and WTI on the Gulf Coast, represented by Magellan East Houston (MEH) is up to $0.83/bbl so far this month (right graph below), and for the past three months has averaged $0.71/bbl (red line). That’s the highest level since 2020. Permian pipelines to Corpus Christi are full, and pipelines to Houston and Nederland are not that far away, leaving pipes north to Cushing the only remaining takeaway capacity – definitely the wrong direction for exports.
The differential is a long way from the 2018-19 spike up to $20/bbl, but it is getting closer to a level that would justify the construction of additional new capacity beyond the Enbridge Grey Oak expansion currently being developed. We believe a sustained differential of $1.25/bbl would do it.
