Arizona's gas prices surge 25 cents in a month—here's why

Arizona's average gas price has climbed by nearly 25 cents in the past month, reaching £2.54 per gallon on Thursday. Despite the recent rise, drivers are still paying less than they were a year ago, when the average stood at £2.72. The increase follows seasonal trends, with prices typically rising in spring and peaking in summer months.

Last month, Arizona's average gas price was £2.35 per gallon. The latest jump comes as refineries switch to summer fuel blends and undergo maintenance, both of which push costs higher. More drivers on the road during summer also boosts demand, adding further pressure to prices.

Nationally, the average price is £2.34 per gallon—lower than Arizona's current rate. However, the state's prices remain far below California's, where stricter environmental rules drive costs up. Over the past five years, California's average has stayed between £4.00 and £5.20 per gallon, while Arizona's has ranged from £2.80 to £3.60. California's Low Carbon Fuel Standard, reformulated gasoline requirements, and cap-and-trade policies all increase production costs, whereas Arizona follows less stringent federal standards.

Global oil prices have fallen recently, helping to offset some of the rise. In February, crude oil averaged £51.40 per gallon. OPEC's increased production and market adjustments after Russia's invasion of Ukraine have also kept oil prices in check.

Arizona's gas prices are now higher than the national average but still below last year's levels. The summer season, refinery changes, and rising demand will likely keep prices elevated in the coming months. Meanwhile, California's stricter regulations continue to widen the price gap between the two states.
