The conflicts in Iran have only just begun, yet Massachusetts commuters are already seeing a significant impact at the gas pump. Fuel prices in the Boston area rose 10 to 30 cents per gallon overnight, with experts attributing the spike to the Strait of Hormuz, where roughly 20% of the world's oil supply passes. While the U.S. only gets 10-15% of its oil from the Middle East, the global nature of the oil market means that disruptions in the region can still drive up prices at the local level.

Why it matters

The rapid rise in gas prices in Massachusetts is a direct consequence of the ongoing conflicts in Iran, highlighting the vulnerability of the global oil supply and the outsized impact that geopolitical tensions can have on everyday consumers. This issue is particularly acute for Massachusetts residents, who rely heavily on personal vehicles for transportation and are now facing higher costs at the pump.

The details

Experts at GasBuddy say the issue stems from the Strait of Hormuz, a critical chokepoint for global oil shipments. Roughly 20% of the world's oil supply passes through this stretch of water along the Iranian coast. While the U.S. only gets 10-15% of its oil from the Middle East, the global nature of the oil market means that disruptions in the region can still drive up prices at the local level. Gas stations will be paying more for their next shipment of fuel, so they are raising prices immediately to cover the increased costs.

  • On March 4, 2026, fuel prices in the Boston area rose 10 to 30 cents per gallon overnight.

What they’re saying

“I was actually looking at the stock market this morning and saw that the price per barrel of oil went up. It's absurd how quickly the market can fluctuate and change. It definitely takes a big impact on my bank account.”

“Here in America, we only get about 10% to 15% of our oil from the Middle East, and the rest comes from either the United States, Canada, Mexico. Basically, basically people who like us. We are not going to run out of supply, but because crude oil is traded in the manner that it is using U.S. dollars, we are going to pay more for it at the pump.”

“Typically, it never works that way because you remember they have already paid a higher price point for the gasoline that is sitting in their underground tanks, so that has to kind of drain out for it to economically make sense.”

What’s next

Experts expect gas prices to rise another 10 to 25 cents per gallon in the coming days and weeks as the conflict in Iran continues.

The takeaway

The rapid spike in gas prices in Massachusetts is a stark reminder of the outsized impact that geopolitical tensions can have on everyday consumers. This issue highlights the vulnerability of the global oil supply and the need for greater energy independence and diversification to insulate local communities from the ripple effects of international conflicts.
