US average gasoline price at $3.9788, falling below $4 for the first time since mid-July

US average gasoline prices fell to $3.9788 per gallon, slipping below the $4 mark for the first time since mid-July, according to AAA data for the morning of the 10th. The national average is down from $4.1493 a week earlier and $4.3669 a month earlier, though it remains about 91 cents above the $3.0707 seen a year ago. GasBuddy analyst Patrick De Haan noted prices have declined almost weekly since peaking at $4.494 on September 24. The drop follows a sharp pullback in international crude prices, driven by renewed expectations that the US and Iran could reach some form of agreement. The move matters for headline inflation and household budgets, and the next signal to watch is whether crude continues to ease or the Iran outlook shifts.
