Rising petrol costs drive sharp inflation increase in US in August

What the report says

US consumer prices rose 0.4% in August, the biggest monthly gain in four months, according to the Department of Labor’s Consumer Price Index report released on Friday. On an annual basis, inflation was 3.4%, unchanged from July. Al Jazeera said higher petrol costs were the main driver of the increase.

The report said petrol prices climbed 3.9% from July and were 27.4% above a year earlier, accounting for about one-third of the month’s overall inflation rise. The average US petrol price also increased by 15 cents over the previous week, reaching $4.30 per gallon, based on data cited from the American Automobile Association. Al Jazeera linked the move to a broader rise in crude oil prices and continued market concerns over tensions between Iran and the US and bottlenecks in the Strait of Hormuz.

The article also noted smaller monthly increases in grocery prices, including eggs, frozen fish, peanut butter and salad dressing, while some items such as lettuce, apples, milk, juice and coffee fell. The inflation data arrived ahead of the Federal Reserve’s policy meeting, where investors were weighing the chances of another interest-rate increase. Beyond the specific report, the piece reflects how energy prices can quickly affect headline inflation and shape central bank expectations in the US.
