U.S. consumer sentiment deteriorated in early September as rising gasoline prices and trade tensions stoked fears of higher inflation over the next 12 months, a survey showed Friday.

The University of Michigan's Surveys of Consumers said its Consumer Sentiment Index dropped to 47.8 this month. The decline reflects growing unease among households about the economic outlook.

The survey highlighted that consumers are increasingly worried about inflation pressures building in the months ahead. Rising gasoline prices have contributed directly to these concerns by increasing everyday costs for families.

Trade tensions have added to the uncertainty, with many respondents expressing anxiety that such developments could lead to broader price increases across goods and services.

The Consumer Sentiment Index is a key gauge of public attitudes toward the economy. A reading at these levels indicates significant pessimism among American consumers.

Friday's report comes as households continue to navigate elevated costs in several areas. Analysts will watch closely for any further shifts in sentiment in the weeks ahead.
