Massachusetts gas prices rose for the second consecutive week and reached an average of $4.01 per gallon of regular fuel on Monday, up from last week’s price of $3.88 per gallon, according to the U.S. Energy Information Administration.
Why are gas prices going up?
Gas prices are jumping around because traders are trying to price in how long the Iran war will disrupt oil flows from the Middle East, on top of the usual spring run-up in demand as driving season approaches. Markets are baking in higher risk and “additional volatility” but not a long-term shutdown, and prices could retreat if it becomes clear the tensions are short-lived, petroleum analyst Patrick De Haan said.
Analysts say another 20 to 30 cents a gallon is still likely in the weeks ahead.
The average fuel price in Massachusetts rose about 25 cents since last month. According to the EIA, gas prices across the state in the last year have been as low as $2.79 on Jan. 26, 2026, and as high as $4.01 on April 27, 2026.
A year ago, the average gas price in Massachusetts was 37% lower at $2.92 per gallon.
