U.S. consumer sentiment fell to a decade-long low in the month of August as concerns over the Delta variant continue to mount.

The University of Michigan study reported a final reading of 70.3 this month compared to 81.2 in July. The current reading fell below the Wall Street Journal’s expectations of 71.0.

“There was no lessening in late August in the extent of the collapse in consumer sentiment recorded in the first half of the month,” said Richard Curtin, the survey chiefs economist.

Consumer sentiment fell to a 10-year low this month, marking a 30-point drop from the 101 level recorded in February of 2020 before the pandemic began. Consumer expectations also slipped from 79 to 65.1 and assessment of current economic conditions fell from 84.5 to 78.5.

Curtin says the collapse does not imply a downturn in the economy and that the pandemic may have impacted American’s attitudes on spending and the decline in sentiment.
