Current case
- Strongest support
Chevron commits $7B to double Venezuelan oil production over five years
Increased availability of heavy crude feedstock for US Gulf Coast refineries, potentially lowering input costs and improving crack spreads.
· Moves refining margin outlook, feedstock cost assumptions
- Main threat
Sky Quarry Inc. Restarts Nevada's Only Crude Oil Refinery at Eagle Springs
Valero is a major independent refiner. The restart of a small refinery in Nevada could marginally alter regional supply dynamics for refined products or demand for crude oil, potentially exerting slight pressure on regional crack spreads or increasing competition for crude inputs.
· Moves regional crack spreads, refinery utilization rates
- Open question

Peer performance and sector sentiment. Similar to MPC, VLO's prospects are tied to the refining industry's health, which PSX's earnings report will shed light on.
