"As concerns over tariffs and policy uncertainties grow, gas prices have continued to decline across much of the country, raising the possibility that the national average could slip below $3 per gallon and approach some of the lowest prices seen in years," said Patrick De Haan, head of petroleum analysis at GasBuddy. "However, this decline shouldn't necessarily be celebrated, as it comes with strong warning signs. When the economy slows, gasoline demand drops-- along with demand for other refined products like diesel and jet fuel. We've already seen some signals that the months ahead could be challenging. All of this suggests that gas prices are likely to remain low for now. However, if economic conditions improve, gas prices could eventually follow suit and start rising again."
