Factors Driving 2026 Prices
- Crude Oil Volatility: Brent crude hovered at $85/barrel in Q1 2026, up 12% from 2025 closes, due to Middle East supply disruptions on April 15.
- Refinery Outages: Pacific Northwest refineries underwent scheduled maintenance February 10-20, reducing output by 15% and spiking local prices 28 cents/gallon.
- Seasonal Demand: Spring break travel May 1-7 boosted consumption 8%, pushing weekly averages up $0.29.
- State Taxes: Washington's 49.4 cents/gallon gas tax, unchanged since 2025, adds $0.20 premium over national norms.
- Federal Policies: President Trump's 2025-2026 energy independence push lowered imports but couldn't offset global crude swings.
"Gas prices in Spokane Valley are a perfect storm of regional refining constraints and global oil politics-expect $5.50+ through summer," says AAA Northwest analyst Maria Gonzalez, April 28, 2026.
