U.S. gasoline prices are broadly easing as oil costs fall amid reduced U.S.-Iran tensions, pushing the national average for regular down to about $3.86 per gallon. The sharpest weekly declines have been concentrated on the West Coast, led by Washington (down about 17 cents) and California (down roughly 15 cents), after earlier spikes. Despite near record travel demand, the pullback in crude supply risk is driving the short-term move, reflecting a geopolitically fueled catalyst in oil and refined products markets.
