Crude oil prices dropped on Saturday after disappointing Chinese trade data and a downgrade of crude demand growth by the International Energy Agency.
New York's main contract, WTI light sweet crude for September delivery, fell below the US$92 level before closing down US49c from Friday at US$92.87 a barrel.
In London, Brent North Sea crude for September slid US27c to US$112.95.
"The dip in price was triggered by weaker Chinese import data," said Commerzbank analyst Carsten Fritsch.
China's exports and imports slowed for the second consecutive month in July, adding to concerns that China's economy is still losing steam.
