US consumer confidence sank for the fourth consecutive month in June.
The Conference Board said its consumer confidence index fell to 62.0 in June, its weakest level since January.
The research firm revised the May reading a half-point lower to 64.4.
A slowdown in consumer spending, which accounts for about 70% of the nation's output, would deal another blow to the already weak economy.
"Consumers were somewhat more positive about current conditions, but slightly more pessimistic about the short-term outlook," said Lynn Franco, the Conference Board's director of economic indicators.
Franco noted that income expectations, which had improved last month, declined in June.
"If this trend continues, spending may be restrained in the short term," she warned.
