Key Drivers of Volatility
Geopolitical instability in the Middle East has disrupted oil supplies, pushing crude prices up 15% since early May and directly impacting Pacific Northwest refineries that supply Spokane. Washington's reliance on imported refined products amplifies these shocks, unlike more self-sufficient regions.
State taxes contribute 12% to the pump price, with recent carbon tax hikes adding 5 cents per gallon effective May 1; coupled with federal taxes at 18.4 cents, taxes alone total over 73 cents.
"We've seen a perfect storm: refinery maintenance delays in Anacortes combined with heightened demand from spring travel," notes local energy analyst Maria Gonzalez in a May 10 interview with KHQ.
- Oil market shocks: Brent crude rose from $78/barrel on May 1 to $92 by May 12, a 18% gain.
- Refinery outages: BP's Cherry Point facility offline since April 25, reducing regional supply by 7%.
- Seasonal demand: Memorial Day travel up 12% per AAA projections, straining inventories.
- Tax burdens: WA's 49.4 cents/gal excise tax plus 6.5% sales tax inflates costs.
- Currency effects: Strong USD eases import costs but lags behind euro-denominated oil trades.
Historical Context
Spokane's May 2026 average of $5.35 eclipses the 2025 monthly figure of $3.90 by 37%, recalling 2022 peaks when prices hit $5.95 amid Ukraine-related disruptions. Year-over-year, diesel has ballooned 54.3%, outpacing regular gas due to trucking sector strains.

Forecast and Outlook
Through May's end, expect $5.30-$5.50 range barring new disruptions; summer blends post-June 1 could ease 5-10 cents if demand softens. Watch OPEC+ output decisions on May 25, projected to add 411,000 barrels/day but offset by U.S. inventory draws of 3.2 million barrels last week.
Locally, Spokane's refinery expansions at nearby Pasco may stabilize supply by Q3 2026, potentially trimming 15-20 cents long-term per WSU energy models.
