Marathon Petroleum (MPC)
Notes
Marathon Petroleum (MPC)
The largest US refiner by capacity — and, uniquely among the three USGC names this project tracks, on record declining the Venezuelan-sourcing leg. Created 2026-08-12 to hold that distinction explicitly, because collapsing MPC into a VLO/PSX/MPC basket would conflate two different exposures.
Why it matters to this project
MPC is the discriminator in venezuelan-heavy-sour-return-to-usgc-coker-differential-capture. It expects the same widening differentials, so it carries the differential beta; it is not buying the Venezuelan barrel, so it does not carry the sourcing alpha. Holding the two apart is what stops the chain from being a sector call dressed as a mechanism.
What is cited about it
From 2026-08-12-autoresearch-venezuelan-heavy-sour-usgc-refiner-capture:
- Marathon Petroleum "says there are 'better options' than Venezuelan barrels for heavy, sour grades."
- Chief Commercial Officer Rick Hessling: spreads will "widen out even a bit more because many of these Venezuelan barrels have not reached the market yet" — i.e. MPC is bullish the differential while declining the feedstock.
Open questions
- What are the "better options"? Canadian heavy via egress, PMI fuel oil, or something else? No source specifies, and the answer would say whether MPC's pass is a logistics judgment or a credit/sanctions one.
