California Fuel Price Projections & Analysis — 2026
California Fuel Price Projections & Analysis — 2026
Published March 9, 2026 • Lodi 411 Special Report
Executive Summary
California faces an unprecedented convergence of pressures on fuel prices in 2026: two major refinery closures removing 18–21% of in-state refining capacity, escalating regulatory costs from CARB's Cap-and-Invest and LCFS programs, and the ongoing U.S.–Iran conflict that has driven crude oil above $110 per barrel. The state's average regular gasoline price stood at $5.16 as of March 8, 2026 — already $1.66 above the national average — and projections range from roughly $5.50 to $8.44 per gallon by late 2026, depending on how these factors unfold.
California Oil Extraction & Imports
California's in-state crude oil production has declined to roughly 23% of consumption, making the state heavily dependent on imports. The state consumed approximately 511 million barrels of crude in 2024, while domestic extraction continues a long-term downward trend driven by field depletion and regulatory constraints.
Governor Newsom signed SB 237 in September 2025 to allow streamlined drilling approvals in Kern County — the state's oil heartland — though 3,200-foot health protection zone setbacks remain in force. This may modestly slow the production decline but cannot reverse it in the near term.
Import Vulnerability: With the Strait of Hormuz — through which roughly 20% of global oil transits — effectively disrupted by the Iran conflict, California's supply chains face particular stress. The state cannot easily substitute in-state production or receive out-of-state gasoline blends due to CARB's unique fuel specifications, which limit the pool of compatible import sources.
Refinery Status & Capacity Crunch
Two landmark closures define California's refining landscape in 2026:
- Phillips 66 (Wilmington/Long Beach) — closed in late 2025, removing approximately 139,000 barrels per day of capacity.
- Valero (Benicia) — idled and set for full closure in April 2026, removing an additional 145,000 barrels per day.
Together, these closures eliminate roughly 104 million barrels of annual processing capacity, dropping total state refining capacity to approximately 488 million barrels per year against 511 million barrels of consumption — a deficit of roughly 23 million barrels annually.
Critical Warning: UC Davis economists project the refinery capacity loss alone will add approximately $1.21 per gallon once the full impact is realized around August 2026. A worst-case USC Marshall School study projects regular gas reaching $7.35–$8.44 per gallon by year-end. If another refinery experiences an unplanned outage (as the PBF Martinez refinery did in early 2025), surplus capacity drops to as little as 1.9% — or goes negative.

Price Components at the Pump
California's per-gallon price structure includes multiple layers of cost beyond crude oil. The table below breaks down every component across four time horizons — from pre-conflict levels in February 2026 through worst-case late-2026 projections.
| Component | Pre-Conflict (Feb 2026) | Current (~Mar 9) | Mid-2026 Projected | Late-2026 Worst Case |
|---|---|---|---|---|
| Crude oil cost | $1.50 | $2.20–$2.50 | $2.00–$2.30 | $2.30–$3.00 |
| Refining cost & margin | $1.05 | $1.10–$1.30 | $1.40–$1.80 | $1.80–$2.50 |
| Distribution & marketing | $0.35 | $0.35–$0.40 | $0.40–$0.50 | $0.50–$0.60 |
| Federal excise tax | $0.18 | $0.18 | $0.18 | $0.18 |
| State excise tax | $0.61 | $0.61 | $0.61 | $0.61 |
| State sales tax + UST fee | $0.12 | $0.12 | $0.12 | $0.12 |
| Cap-and-Invest | $0.24 | $0.24 | $0.24–$0.35 | $0.35–$0.50 |
| Low Carbon Fuel Std (LCFS) | $0.30 | $0.30 | $0.30–$0.65 | $0.65 |
| Total (Regular) | ~$4.35 | ~$5.10–$5.65 | ~$5.25–$6.51 | ~$6.51–$8.16 |
California drivers pay approximately $0.90 per gallon in combined taxes (the nation's highest), plus up to $0.54 per gallon in environmental compliance costs as of early 2025. The LCFS update taking effect July 1, 2026 could add an additional $0.65 per gallon.
Gasoline Price Component Breakdown by Time Period
Prices Across All Four Fuel Grades
Premium and mid-grade carry typical octane premiums of $0.30–$0.70 over regular. Diesel faces its own cost pressures from trucking demand and LCFS compliance.
| Fuel Grade | Octane Premium Over Regular | Current Avg (~Mar 9, 2026) | Projected Range (Late 2026) |
|---|---|---|---|
| Regular (87 octane) | Base | ~$5.16 | $5.50–$8.44 |
| Mid-Grade (89 octane) | +$0.30–$0.40 | ~$5.46–$5.56 | $5.80–$8.84 |
| Premium (91 octane) | +$0.50–$0.70 | ~$5.66–$5.86 | $6.00–$9.14 |
| Diesel | +$0.20–$0.50 (varies) | ~$5.30–$5.60 | $5.70–$8.90 |
Current vs. Projected Fuel Prices by Grade
CARB: Cap-and-Invest Program
California's former "Cap-and-Trade" program was renamed Cap-and-Invest following legislative extension through 2045 in September 2025. On January 13, 2026, CARB released draft amendments proposing aggressive tightening of allowance supply.
Proposed Allowance Reductions
- 2027 cap: 15 million allowances removed
- 2028 cap: 26.5 million allowances removed
- 2029–2030: 35–42 million additional allowances removed
- Cumulative 2027–2045 supply: reduced by 1.02 billion allowances (from 4.81 to 3.79 billion)
Cost Impact: The program currently adds roughly $0.24 per gallon to gasoline costs. Analysts warn the tighter caps, combined with CARB's proposed annual allowance retirement mechanism starting December 2027, could push that to $0.50 per gallon or more. The Board is scheduled to vote on amendments on May 28, 2026, with the new trajectory effective January 1, 2027. State Senator Suzette Valladares has warned the program alone could add approximately $1.00 per gallon to fuel costs.
Governor Newsom's Gas Tax & Policy Actions
Rather than a direct gas tax cut, Governor Newsom's approach has focused on expanding supply and fuel options:
- AB 30 (October 2025): Allows E15 fuel (15% ethanol) to be sold in California. UC Berkeley estimates this could lower prices by $0.20 per gallon and save $2.7 billion annually, though it requires infrastructure upgrades at fuel stations.
- SB 237: Enables streamlined Kern County oil drilling to boost domestic supply and authorizes the governor to temporarily suspend summer-blend (low RVP) fuel requirements during price spikes.
Meanwhile, California Democrats blocked Republican bills (AB 12) that would have suspended the LCFS gas price increase of $0.65 per gallon set for July 1. A new road usage charge for EVs and hybrids is being debated under AB 1421, which would replace gas tax revenue lost to electrification — though it has drawn intense criticism.
Gas Tax Status: No significant reduction to the $0.61 per gallon state excise tax has been enacted or formally proposed by Newsom. The state's annual inflation adjustment raised it from $0.596 to $0.612 on July 1, 2025. Revenue from the gas tax funds road maintenance and infrastructure projects, and with EV adoption reducing collections, lawmakers face pressure to maintain or even restructure — not cut — the tax.
U.S.–Iran Conflict: Crude Oil & Natural Gas
The U.S.–Iran conflict, now in its second week as of March 9, has produced the most dramatic oil market disruption in years:
- Crude oil surged past $114 per barrel on Monday March 9, a 23–25% spike, with Brent briefly hitting $111 and WTI $111.24 — the highest levels since 2022.
- The Strait of Hormuz was effectively closed Monday, disrupting roughly 20% of global crude and natural gas supply.
- Natural gas rose to approximately $3.34 per MMBtu, up 4.6% from Friday's $3.19 close, following an 11% increase the prior week.
- Saudi Arabia is ramping Red Sea exports but cannot fully offset Hormuz disruptions.
Pump Impact Formula: Governor Newsom noted that every $10 per barrel increase translates to roughly $0.24 per gallon at the pump. The conflict compounds California's already tight supply by threatening the import pipeline that must replace lost refinery capacity.
CNBC analysts suggest energy prices will stabilize once U.S. military operations degrade Iran's ability to threaten shipping lanes — but the timeline for that remains highly uncertain.
Fertilizer Impact
Natural gas is the primary feedstock for nitrogen fertilizer production. The Iran conflict has produced immediate price effects:
- Urea prices at the Port of New Orleans have seen "significant" increases following the attack on Iran.
- Fertilizer prices were already rising steadily before the conflict, and the natural gas spike threatens further escalation.
- Analysts warn the conflict could strain U.S. agricultural input costs broadly, with California's Central Valley — heavily dependent on imported fertilizer — particularly exposed.
Agricultural Impact for Lodi & San Joaquin Valley: Higher fertilizer prices directly affect grape growers, almond orchards, and row crop producers throughout the region. Nitrogen fertilizer (urea, ammonium sulfate) costs could increase 30–80% from pre-conflict levels by mid-2026, depending on the duration of the Strait of Hormuz disruption and whether domestic natural gas prices stabilize. This adds pressure to an already challenging cost environment for local agriculture.
Crude Oil Price Trajectory & Iran Conflict Impact
2026 Price Projection Scenarios
The following table presents three projection scenarios for California fuel and fertilizer prices through the remainder of 2026, based on the interplay of refinery closures, regulatory costs, and geopolitical factors.
| Scenario | Regular Gas (Late 2026) | Diesel (Late 2026) | Nitrogen Fertilizer (per ton, CA) |
|---|---|---|---|
| Optimistic — Quick Iran resolution, stable refining, E15 adoption | $5.00–$5.75 | $5.20–$5.80 | $350–$425 |
| Base Case — Moderate conflict duration, Valero closes April, LCFS kicks in July | $6.00–$7.35 | $6.00–$7.00 | $450–$575 |
| Pessimistic — Prolonged conflict, tighter Cap-and-Invest, refinery outage | $7.35–$8.44 | $7.00–$8.90 | $600–$800+ |
Scenario-Based Fuel Price Projections: All Four Grades
Key Drivers of the Range
- Crude oil trajectory: If the Strait of Hormuz reopens quickly, crude could retreat toward $70–$80 per barrel; prolonged closure keeps it above $100.
- Valero Benicia closure timing: The April 2026 shutdown is the single largest domestic supply shock, adding an estimated $1.21 per gallon by August.
- LCFS update (July 1, 2026): Could add up to $0.65 per gallon if not suspended by the governor.
- Cap-and-Invest tightening: New allowance scarcity beginning 2027 will be priced into futures markets in late 2026.
- Natural gas prices: Sustained increases above $4 per MMBtu would significantly raise both refining costs and fertilizer prices for California agriculture.
Bottom Line: California's structural vulnerability — declining extraction, shrinking refinery capacity, unique fuel blend requirements, and growing reliance on imports through geopolitically exposed supply chains — means fuel and fertilizer prices face persistent upward pressure regardless of which scenario materializes. The most likely outcome (base case) points to regular gasoline averaging $6.00–$7.35 per gallon by late 2026, with diesel tracking slightly below and nitrogen fertilizer delivered to the Central Valley running $450–$575 per ton.
