BATON ROUGE, La. — Average gasoline prices in Louisiana increased 1.7 cents per gallon over the past week, reaching $3.56 per gallon, according to a survey of 2,436 stations by GasBuddy.
Prices are now 106.8 cents higher than a month ago and 83.8 cents above levels recorded a year earlier, reflecting sustained upward pressure tied to global oil supply disruptions.
The national average gasoline price also rose, climbing 2.4 cents over the past week to $3.95 per gallon. That figure is up 97.9 cents from a month ago and 83.8 cents higher year over year, based on data compiled from more than 11 million weekly price reports across over 150,000 U.S. gas stations.
Diesel prices posted sharper gains, with the national average increasing 14.3 cents الأسبوع-over-week to $5.369 per gallon. That marks the highest level since July 27, 2022.
Within Louisiana, price disparities remain wide. The lowest recorded price was $3.19 per gallon, while the highest reached $4.40 per gallon, a spread of $1.21.
Regional trends showed mixed movement. Prices in Baton Rouge averaged $3.51 per gallon, down slightly from the previous week. Jackson held steady at $3.57 per gallon, while New Orleans saw a modest increase to $3.57 per gallon.
Historical data highlights the sharp rise in fuel costs over time. On March 30, 2025, gasoline in Louisiana averaged $2.73 per gallon, compared with $3.56 per gallon כיום. The national average stood at $3.11 per gallon a year ago.
Patrick De Haan, head of petroleum analysis at GasBuddy, said tightening global supply conditions are driving the increases.
“Gasoline and diesel prices continue to climb to multi-year highs as the effective closure of the Strait of Hormuz curtails the flow of millions of barrels of crude oil each day,” De Haan said. “The situation remains highly volatile and unpredictable, but upward pressure on fuel prices is likely to persist as long as global oil supplies are constrained by the continued disruption in the Strait.”
He added that the national average for gasoline could surpass $4 per gallon, while diesel prices may approach $6 per gallon if conditions do not improve.
Americans have already spent nearly $8 billion more on gasoline over the past month, a trend that could weigh on broader economic activity. Rising diesel costs may also contribute to renewed inflationary pressure, according to the analysis.
