The average price of a gallon of regular gas in the U.S. fell to $4.04 on Tuesday, a slight but noticeable drop from recent highs. The move came as crude oil briefly slid below $80 a barrel, driven in part by growing anticipation of a diplomatic breakthrough between the United States and Iran.
A Friday deadline for the Strait
U.S. and Iranian officials are set to sign a truce on Friday that would reopen the Strait of Hormuz, the narrow waterway through which about a fifth of the world's oil passes. The strait has been a flashpoint in recent weeks after Iran threatened to block tanker traffic, sending shockwaves through global energy markets.
If the deal goes through, it could ease supply fears and push gas prices lower. But the market isn't betting big on that outcome just yet. Polymarket, a prediction platform, puts the probability of a signed Iran deal at 46% — essentially a coin flip.
Why $4.04 still hurts
Even with Tuesday's dip, gas prices remain well above where they were a year ago. The $4.04 figure is a national average; drivers in some states are still paying closer to $5. The decline from recent peaks reflects a mix of lower crude costs and cautious optimism that the Strait of Hormuz won't be shut down.
Oil analysts watching the situation note that a reopening would let tankers move more freely, potentially adding millions of barrels a day to global supply. That's a big if. The truce signing is scheduled, but implementation details remain unclear.
What's at stake at the table
The U.S.-Iran talks go beyond just oil. The Strait of Hormuz has been a lever for Iran in nuclear negotiations and regional tensions. A truce would not resolve all disputes, but it would remove an immediate threat to energy flows. The Friday signing is the first concrete step in months.
For American drivers, the immediate takeaway is simple: gas might get cheaper if the deal holds, or it could spike again if it falls apart. The next few days will tell.
