INDIANA — Average gasoline prices in Indiana have jumped by 14.5 cents per gallon over the past week, bringing the state average to $3.49 per gallon today, according to the latest survey of 3,271 stations conducted by GasBuddy.

That figure is up 23.9 cents from a month ago and sits 95.6 cents higher than a year ago, based on GasBuddy data compiled from more than 11 million weekly reports covering over 150,000 stations across the country.

Geopolitical Factors Driving Up Costs
Energy analysts attribute the price spikes primarily to volatility in global oil markets caused by geopolitical tensions.
“Average gasoline and diesel prices rose in nearly every state over the last week, as continued escalations between the U.S. and Iran, renewed Houthi attacks in the Red Sea, and fresh Ukrainian strikes on Russian oil refineries combined to keep upward pressure on both crude and refined product markets,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
However, De Haan noted that relief could be on the horizon.
“A weekend pullback in hostilities offered some relief, with oil prices opening sharply lower Sunday, suggesting the pace of increases at the pump may moderate in the days ahead,” De Haan added. “For now, motorists should expect prices to remain elevated, but the intensity of further gains will depend heavily on how the geopolitical situation develops in the coming week.”
