California gas prices highest since 2023

Gasoline is suddenly a California story again — not just an annoying one, but a supply-chain one. Prices have climbed above $6 a gallon statewide, the highest level since 2023, just as the last tanker carrying crude that made it through the Strait of Hormuz reached Long Beach. California officials say gasoline and diesel inventories cover roughly four to six weeks of normal demand. ### Why is California getting hit harder? Because California is unusually boxed in. The state runs a specialized fuel system, has limited pipeline connections to the rest of the country, and imports a meaningful share of crude from overseas. One widely cited estimate in this week’s coverage puts roughly 30% of California’s foreign crude imports coming from the Persian Gulf. When the Hormuz route gets disrupted, California cannot just swap barrels as easily as Gulf Coast states can. ### What changed this week? The immediate trigger was logistics, not just fear. A final shipment of Persian Gulf crude arrived in Long Beach after making it through Hormuz, and now refiners have to replace that flow with alternate supplies and alternate routes. That is the kind of change that turns an oil-market headline into a local pump-price problem. One report pegs the missing volume at about 200,000 barrels a day that California now has to replace somehow. ### How bad are prices right now? As of May 6, 2026, AAA shows California regular at $6.16 a gallon. Diesel is much worse at $7.50 statewide. The national average for regular is $4.54, so California drivers are paying a premium of more than $1.60 a gallon versus the U.S. average. That gap matters because it tells you this is not just a global oil spike — it is a California-specific squeeze layered on top of the global one. ### Does “four to six weeks” mean stations run dry? Not necessarily — but it is not a comforting number either. The California Energy Commission’s message is basically that inventories are adequate for normal demand in the near term while refiners look for substitute crude and reroute supply. The catch is that “normal demand” is doing a lot of work there. If panic buying starts, if refinery operations stumble, or if replacement cargoes are slow to arrive, the buffer shrinks fast. ### Why does refinery capacity matter so much here? Because California has less slack than it used to. Even before this Hormuz shock, the state was already dealing with a tighter refining system and years of concern about plant closures or restructurings. In a market with lots of spare capacity, a disrupted crude stream is painful but manageable. In a market with thin margins for error, the same disruption gets amplified into sharper price moves and more anxiety about supply duration. ### Why should freight and warehouses care? Fuel is a direct operating cost, but distance is the multiplier. When diesel spikes and supply feels shaky, every extra mile gets more expensive — drayage, regional trucking, repositioning, all of it. That makes infill warehouses more valuable because they cut miles, shorten port-to-customer trips, and reduce exposure to exactly the kind of fuel volatility California is dealing with now. This is where an energy shock turns into a real-estate and logistics story. The warehouse itself did not change — the math around it did. ### So what should people watch next? Watch three things — whether alternate crude cargoes start landing, whether refinery operations stay steady, and whether retail prices keep outrunning the national move. If those replacement flows show up quickly, this stays painful but temporary. If they do not, California’s already expensive fuel market could stay under pressure well beyond this first four-to-six-week window. ### Bottom line This is not just “gas is expensive” news. It is a reminder that California’s fuel system is isolated, specialized, and easy to stress. When one global chokepoint closes, the effect lands at the pump fast — and then ripples outward into freight costs, delivery economics, and where supply chains want to be.
