Phillips 66

Refining margins are largely market‑set; PSX can optimize feedstock and yields but cannot sustainably raise prices. Midstream tariff escalators help but are constrained by FERC indexation.

The current five‑year index through June 2026 is PPI‑FG +0.78 percent; the Commission has initiated the next review proposing PPI‑FG −1.42 percent for July 2026–June 2031, a headwind for tariff growth if finalized. M&S pricing is competitive, and CPChem margins remain cyclical.

Net: limited structural ability to raise prices without volume risk, partially offset by mix shift to fee‑based assets.
