Analysis suggests rising energy costs, with US gasoline averaging $4.03/gallon (up from $3.87 a month ago), could reignite August inflation after July's cooling. Falling energy prices, including a 2.9% month-over-month drop in gasoline and a 1.7% decline in fuel oil, helped moderate inflation in July. However, rising crude prices and strong refining margins are now pushing fuel costs higher, indicating this relief may be temporary and could exert renewed upward pressure on August inflation.
