NEW YORK (CNN/Money) - Consumer confidence posted a sharp decline last week as investors worried that rising energy prices could have a negative impact on the economy, a published report said Tuesday.

The ABC News/Money magazine Consumer Comfort index fell to -16 on its scale of +100 to -100 in the week ended May 23, 2004, compared to -11 in the previous week.

Earlier Tuesday, the Conference Board, said its monthly gauge of consumer confidence edged up in May to 93.2 from 93.0 in April.

Gasoline and oil prices have been trading near their all-time highs in recent weeks. The average retail price of gasoline nationwide jumped 4.7 cents last week to $2.064 per gallon, according to a government report released Monday. Light crude for July delivery also reached a new high of $41.72 per barrel, but dropped back to $41.14 on Tuesday.

The ABC/Money index has averaged -9 since the weekly poll began in December 1985.
