Michigan drivers are now paying an average of $3.55 per gallon for regular unleaded gas after prices spiked 56 cents in the past week, according to AAA. This price is 72 cents per gallon more than this time last month and 51 cents more than this time last year.

Why it matters

The sudden and sharp rise in gas prices is being driven by a spike in global oil prices following U.S. strikes on Iran and the closure of the Strait of Hormuz, a critical global oil chokepoint. This is impacting fuel markets and could lead to further price increases of 20-50 cents per gallon in many states this week.

The details

GasBuddy's head of petroleum analysis, Patrick De Haan, said the fuel markets are "rapidly recalibrating to the risk of prolonged disruption to global supply flows" and that diesel prices may rise even more sharply, by 35-75 cents per gallon. In Metro Detroit, the current gas price average is $3.49 per gallon, about 47 cents more than a week ago and 46 cents more than this time last year.

  • On Monday, March 9, 2026, AAA reported the 56-cent per gallon spike in Michigan gas prices over the past week.

What they’re saying

“In just a week, consumers have seen gasoline prices surge at one of the fastest rates in years after oil prices spiked following U.S. strikes on Iran and the effective closure of the Strait of Hormuz.”

What’s next

Analysts expect gas prices in many states could climb another 20 to 50 cents per gallon this week as fuel markets continue to react to the global supply disruptions.

The takeaway

The sudden and sharp rise in Michigan gas prices is a stark reminder of the volatility of global oil markets and the impact that geopolitical tensions and supply disruptions can have on everyday consumers at the pump.
