Fuel costs across Idaho have spiked sharply this week, with the statewide average reaching $4.42 per gallon Monday—placing Idaho among the nation’s priciest markets for gasoline. The Lewis-Clark Valley is experiencing some of the state’s steepest increases, reflecting broader pressures on energy costs in the Pacific Northwest.
Lewiston drivers faced an average pump price of $4.27 per gallon Monday, following a 20-cent jump in recent days. The surge outpaces increases in other major Idaho cities: Boise posted a 14-cent gain, while Coeur d’Alene rose 10 cents over the same period.
Week-over-week, Idaho’s statewide average climbed 7 cents. Over the past month, the increase has reached 37 cents per gallon, and year-over-year, prices have jumped 91 cents—a significant burden for households and businesses dependent on transportation and fuel-intensive operations.
Idaho’s ranking as the seventh-most expensive state for gasoline reflects supply chain dynamics, regional refining capacity, and transportation costs specific to landlocked markets. The Lewis-Clark Valley’s reliance on fuel transported over mountain passes amplifies price volatility compared to coastal states with direct access to refineries and distribution infrastructure.
For rural Nez Perce County residents and businesses, elevated fuel costs ripple through daily operations—from agricultural equipment to logging trucks to long-distance commutes across Highway 12 corridors. Regional freight depends heavily on diesel and gasoline supplies, making energy prices a key factor in local economic competitiveness.
Energy markets remain volatile, and prices can shift daily based on crude oil futures, seasonal demand, and refinery outages. Drivers in the region should monitor local pump prices and consider fuel efficiency measures as prices stabilize or shift.
