Boise gas prices are up 21 cents in a week. Experts weigh in on what’s ahead
Gas prices are once again on the rise in the Treasure Valley—and Boise drivers are feeling it at the pump.
The average price for a gallon of regular gas in Boise climbed 21.2 cents over last week, reaching $3.30 as of Monday, June 23, according to a GasBuddy survey of 216 stations. That’s 23 cents higher than a month ago but still 21 cents cheaper than prices a year ago.
Average prices on Wednesday, June 25 were noted at $3.43 by AAA.
The increase comes as oil markets respond to rising tensions between Iran, Israel, and the United States, which have driven up crude oil prices globally.
“With Israel and Iran trading attacks over the past week, oil prices have continued to climb—and gasoline prices are following suit, rising at a pace we haven’t seen since last summer,” stated Patrick De Haan, head of petroleum analysis at GasBuddy, in a news release. “Motorists should anticipate a continued steady climb in prices.”
Here’s what gas costs around Boise as of June 24, according to GasBuddy:
- Average: $3.30
- Cheapest station: $3.14
- Most expensive station: $3.89
- Price range in Boise: 75 cents per gallon
- Statewide range: $3.14 to $5.40 (a $2.26 difference)
State and regional snapshot, according to GasBuddy:
- Idaho statewide average: $3.36 (up 9.6 cents from last week)
- Ogden, Utah: $3.20 (up 3.9 cents)
- Oregon: $4.02 (up 8.1 cents)
- Washington: $4.46 (up 4 cents)
- National average: $3.18 (up 9.7 cents)
The state ranks among the top 10 most expensive for fuel nationwide, although still below regional neighbors like Oregon, California, and Washington, according to AAA Idaho.
Counties in Idaho with the highest average prices, according to AAA Idaho, included Clark ($3.81), Camas ($3.75) and Clearwater ($3.71). Counties with the lowest average prices included Franklin ($3.29), Boise metro ($3.31) and Caribou ($3.35).
Why are prices rising?
Ongoing conflict between Iran and Israel has rattled global oil markets. U.S. military action has added to uncertainty, pushing crude oil prices higher.
There’s also an increased summer travel demand, with more Americans hitting the road. That seasonal uptick in demand contributes to higher fuel prices.
While analysts say prices may rise another 7 to 15 cents nationally this week, they’re not expecting worst-case spikes like those seen in the past.
“If there are no disruptions in global crude oil supplies, crude prices may settle down, which in turn would help ease climbing gas prices. But with the volatility in crude prices, plus the seasonal increases in demand for gas, we’ll likely see gas prices climb in the short term,” Marie Dodds, public affairs director for AAA Idaho stated in a news release.
