Gas prices in California have surged to an average of $6.06 per gallon, marking the highest level in four years. This increase coincides with a rise in national prices, which now average $4.39 per gallon, driven by a 27-cent increase this week. The surge is largely attributed to the ongoing conflict with Iran, which has disrupted global oil supplies and significantly impacted U.S. consumers, costing them an additional $21.7 billion since March 1. California's unique situation, characterized by strict emissions standards, high taxes, and reliance on imported petroleum, makes it the most expensive state for gas. Fuel stockpiles in California hit record lows in April, and gasoline imports have sharply declined. Governor Gavin Newsom has publicly criticized former President Donald Trump, suggesting that rising gas prices are a direct result of the Iran war. The increase in gas prices has led to a noticeable change in consumer behavior, with many Americans planning fewer vacations and opting against long drives.
