After pushing refineries out, California is importing more foreign fuel

California’s gas is taking a long trip

You fill up and assume the fuel came from somewhere nearby. In California right now, that is less and less true. More gasoline is arriving by ship, and it can travel thousands of miles first.

One big reason is that refinery capacity is shrinking inside the state. When local supply tightens, traders look overseas to keep stations stocked. That shift can make prices feel jumpier for everyday drivers.

A record import month changed the story

In November 2025, California imported more gasoline than at any time on record. More than 40% of those imports came from the Bahamas, which surprised a lot of people watching the market. That is a major shift in where California’s fuel is routed.

This does not mean the gasoline was refined in the Bahamas. The Bahamas can act like a shipping hub where cargoes are staged and redirected. The key point is that the supply chain is becoming more global.

Why California prices stand out

California’s statewide average gas price was about $4.63 on Feb. 25, 2026. The AAA national average was about $2.98 the same day, showing a wide gap. That difference hits commuters, gig workers, and families fast.

Prices are shaped by many factors at once. California has unique fuel rules, a tight supply system, and high demand in big metros like Los Angeles and the Bay Area. When any piece gets stressed, prices can spike quickly.

Refinery closures are a big driver

Phillips 66 announced plans to cease operations at its Los Angeles-area refinery in the fourth quarter of 2025. Reuters also reported the company planned to begin winding down operations by October 2025. Less local refining means the market needs replacement barrels.

When a major facility slows down, it changes how traders plan supply. Instead of pulling from nearby production, they book cargoes that arrive by ship. That pivot can happen faster than most drivers realize.

Another shutdown is right on the calendar

Valero has said it plans to idle major processing units at its Benicia refinery by the end of April 2026. Reporting also described layoffs beginning in mid-March 2026. That removes another major source in a state already running tight.

Even if you never drive near Benicia, the ripple can be statewide. Northern California and Southern California share the same fragile balancing act during disruptions. When the buffer shrinks, import dependence grows.

Little-known fact: PHMSA says it regulates nearly 190,000 miles of hazardous liquid petroleum pipelines in the U.S.

California is an “energy island”

California is geographically isolated from other U.S. refining centers. EIA notes there are no pipelines supplying California across the Rocky Mountains, which limits quick backup options. That is why marine deliveries matter so much.

In many states, a supply pinch can be eased with pipeline shipments from another region. In California, it is often tankers, not pipelines, that save the day. Ships take longer, so planning becomes more sensitive.

Little-known fact: CARB says California reformulated gasoline rules do not require ethanol, even though ethanol is commonly used as an oxygenate.

The Bahamas route, explained simply

The Bahamas can function as a mid-point where fuel cargoes are stored, blended, or reassigned. Bloomberg reported that this circuit has become more common as California books more imports. That helps traders manage timing and shipping options.

This is not just a “one-off” shipment story. When the same route shows up again and again, it becomes part of regular supply planning. That can make California more connected to global shipping costs.

Little-known fact: MARAD notes the Jones Act is codified as 46 U.S.C. § 55102 for water transport of merchandise between U.S. points.

The Jones Act shapes shipping costs

The Jones Act applies to cargo moved by water between U.S. points. MARAD explains that it requires U.S.-built, U.S.-owned, U.S.-registered, U.S.-crewed vessels for that coastwise trade. That limited vessel pool can raise costs.

When domestic shipping is expensive or hard to book, traders look for alternatives. That can make an international leg feel cheaper than a direct U.S.-to-U.S. coastal run. It is a policy detail that shows up at the pump.

California’s special fuel blend matters

California requires a specific reformulated gasoline with strict standards. CARB’s gasoline program explains that these rules have existed in phases since the early 1990s. Not every refinery is set up to make compliant gasoline.

That means the supplier pool is smaller than you might think. When local refineries reduce output, the state cannot just buy any standard gas from anywhere. Imports often need to come from refineries that can meet California specs.

Long-distance shipping adds real costs

Shipping fuel by tanker adds time, port fees, and charter costs. Bloomberg reported the longer journey adds another layer of cost to California’s already expensive gasoline market. Those costs can filter into wholesale pricing.

Ships also face real-world delays. Weather, port congestion, and canal schedules can all shift arrival dates. When inventory runs tight, even small delays can matter.

Imports can keep stations supplied

The upside of imports is simple: they help prevent shortages. When a refinery shuts down or a unit goes offline, cargoes can be booked to fill the gap. That is one reason November 2025 imports spiked to a record.

But imports are not a perfect replacement. They are slower than local production, and they depend on shipping markets. So California can feel steadier one week and stressed the next.

Why price swings can feel sharper

EIA explains California often pays more because its system is isolated and its fuel is specialized. When the market is tight, the state has fewer easy “plan B” options. That makes prices more sensitive to disruptions.

Think of it like a small pond, not a huge lake. If supply drops a little, the impact is bigger and faster. That is why refinery news can translate into pump pain quickly.

What state leaders are watching

In the Benicia situation, reporting said state officials, including Gov. Gavin Newsom, were working with Valero around supply stability and price spikes. The goal is to avoid sudden shortages while the market adjusts. That kind of coordination becomes more important during transitions.

Officials also watch inventory levels and retail pricing trends. When imports become a bigger share, tracking shipments and timing matters more. The state is trying to manage risk, not rewrite global markets.
