Good news at the pump: Gas prices in the U.S. have fallen to their lowest level in over a month. But don't get too comfortable—an analyst warns that if tensions with Iran don't ease, those savings could evaporate fast.

According to GasBuddy analyst Patrick De Haan, the national average gas price dropped to $4.296 per gallon on Sunday, the "lowest level in over a month." In a post on X, De Haan noted that "49 of 50 states are seeing lower prices vs a week ago." But he cautioned that prices could "once again spike" if there isn't "a deal with Iran" to reopen the Strait of Hormuz.

The American Automobile Association (AAA) reported a similar trend: the national average was $4.322 on Monday, June 1st, down from $4.336 on Sunday. Diesel, meanwhile, averaged around $5.448 per gallon.

While gas prices are falling, crude oil prices are heading the other way. West Texas Intermediate (WTI) crude broke the $90 threshold again, trading at $91.40 per barrel at press time. Brent crude rose 3.69% to $94.48 per barrel. The United States Oil Fund (USO), which tracks WTI crude, gained 3.29% in pre-market trading to $133.34.

The backdrop to all this is the ongoing conflict between the U.S. and Iran. The U.S. conducted another set of strikes in Iran in response to "aggressive Iranian actions," including the shooting down of a U.S. MQ-1 drone operating over international waters, according to U.S. Central Command.

President Donald Trump, however, urged people to "relax," saying that Iran is going to make a deal and that it will be beneficial for the U.S.

Not everyone is waiting for a deal. Investor Ross Gerber sees the situation as a "great opportunity" for the world to pivot away from oil and fossil fuels toward alternative energy sources. If that happens, he argues, the Strait of Hormuz becomes "meaningless."

For now, drivers are enjoying a brief respite at the pump. But with crude oil prices climbing and geopolitical tensions unresolved, the path forward for gas prices remains uncertain.
