Middle East impact on gas prices
The nation’s average price of gasoline has increased for the second straight week, rising more than $0.09 compared to a week ago and stands at $3.22 a gallon for regular gas as of Tuesday.
According to GasBuddy, oil markets have been volatile the last two weeks in response to attacks between Israel and Iran — followed by President Donald Trump’s ordered U.S. attack on Iran’s nuclear facilities on Saturday.
Iran launched another missile attack on Israel on Tuesday, despite Trump’s claims of a ceasefire agreement between the two countries hours earlier.
“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,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Additionally, average diesel prices recorded their largest weekly jump since August 2023. Now, with the U.S. launching attacks on Iran, oil prices are likely to continue trending higher.”
De Haan added, however, that he did not expect “apocalyptic spikes” in gas prices.
“For now, motorists should anticipate a continued steady climb in prices, with the national average likely to increase another 7 to 15 cents this week, while diesel could rise by 10 to 20 cents,” De Haan said. “These forecasts remain fluid and could shift quickly depending on global developments.”
