Illinois Gasoline Prices Surge 21.2 Cents per Gallon in One Week

Gasoline costs in Illinois hit $4.47 per gallon this week. The jump is driven by geopolitical tensions affecting global supply.
Average gasoline prices in Illinois rose 21.2 cents per gallon over the past seven days. The state average now stands at $4.47 per gallon. This figure is 15.0 cents higher than the price recorded one month ago. Compared to the same period last year, prices are up $1.04 per gallon. Data from GN auto markets/energy: gasoline prices confirms the sharp weekly increase.
National trends mirror the regional spike. The U.S. average price increased by 17.2 cents per gallon to reach $4.25. Diesel costs saw a larger jump, rising 31.6 cents per gallon to $6.183. Analysts attribute these moves to escalating geopolitical friction. Tensions between the U.S. and Iran have disrupted market confidence. New hostilities in the Red Sea further complicate shipping routes. The shutdown of Saudi Arabia’s East-West pipeline adds pressure to global refined product supplies.
Regional price gaps widen
Price variation within Illinois remains significant. The cheapest station sold fuel at $3.75 per gallon yesterday. The most expensive station charged $5.69 per gallon. This creates a spread of $1.94 between the lowest and highest prices. Neighboring areas show similar volatility. Peoria prices rose 40.7 cents to $4.54 per gallon. Champaign prices increased by 40.6 cents to $4.50 per gallon. St. Louis saw a smaller rise of 5.8 cents to $4.04 per gallon.
Supply disruptions continue
Refinery attacks in Russia have removed additional capacity from the market. Two more facilities are offline due to recent incidents. This loss likely offsets seasonal demand drops. Patrick De Haan of GasBuddy notes that diesel prices may climb faster. The scale of geopolitical escalation makes price relief unlikely. Motorists should expect continued volatility in fuel costs. The transition to cheaper winter-blend gasoline is insufficient to counteract supply shocks.
Historical context for fuel costs
Current Illinois prices are higher than in recent years. In September 2024, the average was $3.41 per gallon. In September 2023, it stood at $3.95 per gallon. The 2022 average was also $3.95 per gallon. In 2021, the price was lower at $3.27 per gallon. These figures show that current levels are near the five-year high. The national average has followed a similar upward trajectory. Sustained global tensions will likely keep prices elevated for the near term.
