When will gas prices go down? Prices hit records as Iran war fuels uncertainty. Ivana Pino · Senior Writer M Michelle Coffey · Senior Editor, Personal Finance Wed, September 9, 2026 at 12:23 PM EDT 4 min read The national average price of gasoline hit a record high over Labor Day weekend as new escalations in the war between the U.S. and Iran triggered a spike in oil prices, with Brent crude futures hitting $100 per barrel for the first time since July.

As of Sept. 9, regular gas was $4 per gallon, with diesel sitting at over $5 per gallon, according to AAA. Crude oil prices were trading above $90 per barrel, and Brent crude was above $100 per barrel.

However, despite elevated fuel prices, as a new season approaches, there may be hope for drivers who are feeling the pinch.

In-Depth Developments & Factual Context

"Generally speaking, we do tend to see gas prices decline in the fall, for the opposite reason of why they go up in the spring," De Haan said in an interview with Yahoo Finance. "In the fall, people stay closer to home, road trips wind down, and people get back to their grind. Temperatures cool off, so there's less outdoor activity, and then we also start to switch back to cheaper winter blends of gasoline in the fall."

Experts say it will take time for consumers to feel the ripple effects of lower oil. Changes in crude-oil prices can affect gas prices fairly quickly; however, the comedown from a gasoline price spike isn't always immediate.

While oil prices are a key driver of what you pay at the pump, they don't tell the whole story. Other factors, such as refining costs, disruptions in gasoline distribution, and retailers' price markups, can slow the rate at which gas prices return to normal after a spike.

Industry Impact & Strategic Analysis

"There is a saying that pump prices rise like a rocket and fall like a feather, and that holds," said David Doherty, head of natural resources research at BloombergNEF. "It takes about three weeks for crude price rises to be fully felt in the price of gasoline prices, and it can take as much time for them to decline as refiners face an uncertain landscape when it comes to the price of crude, their main ingredient."

Here at home, steps are being taken at the federal level to ease the financial burden of higher gas prices on everyday Americans.

This includes the government's emergency EPA waivers , which allow nationwide sales of E15, gasoline blended with 15% ethanol, and the removal of all federal impediments to selling E10, gasoline blended with 10% ethanol, across the country. The EPA says this move will prevent disruption in America's fuel supply by keeping E15 on the market and giving Americans more fuel options.

Forward Outlook & Market Perspective

Additionally, in March, the Trump administration ordered the release of 172 million barrels of oil from the U.S. Strategic Petroleum Reserve (SPR) alongside the 32 member countries of the International Energy Agency, who unanimously agreed to release a total of 400 million barrels of oil from their emergency reserves to address the global disruption.

Federal data shows that oil inventories in the SPR dipped below Biden-era lows earlier this summer and are now hovering around levels last seen in the early 1980s . A total of about 130 million barrels have been released from the SPR since early April.
