Weekly Price Tracker

| Date | Phoenix Average ($/gallon) | Week Change | Arizona Average | Key Driver |
|---|---|---|---|---|
| May 2 | 4.65 | Baseline | 4.62 | Stable supply |

Historical context reveals Phoenix prices 18% above May 2025's $4.03 average, echoing 2022 peaks of $5.69 during summer shortages.
Key Drivers Behind the Rise
- Geopolitical tensions: Iran's recent naval maneuvers in the Strait of Hormuz spiked crude 7%, adding 9 cents/gallon locally per AAA estimates.
- Refinery maintenance: Chevron's El Segundo plant (key supplier) offline since April 28, reducing California pipeline flows to Arizona by 15%.
- Summer blend switch: Mandatory cleaner fuel formulation increased costs by 6 cents/gallon statewide.
- OPEC+ production cuts: Extended 1.1 million barrel/day reductions through Q2 2026 tightened global supply.
- Local demand surge: Phoenix tourism up 12% for Cinco de Mayo weekends boosted Valley consumption.
"Phoenix drivers are hit hardest due to our pipeline endpoint status and strict emissions regs," notes AAA Arizona spokesman Julian Paredes. These factors compound, with 62% of the hike attributable to oil prices per GasBuddy analyst Patrick De Haan.
"Expect another 10-15 cents rise by Memorial Day if tensions persist-fill up midweek at independents." - Patrick De Haan, GasBuddy Head of Petroleum Analysis
