World oil prices fell this morning as investors fretted about the faltering US economic recovery ahead of the release of more key data later this week, analysts said. New York's main contract, light sweet crude for delivery in October, shed $1.08 to $73.62 a barrel. Brent North Sea crude for October delivery shed 93 cents to $75.67 in morning deals. Trader sentiment was battered last night by a report from the US Commerce Department that showed personal incomes rose just 0.2% in July, less than the predicted gain of 0.3%. Markets were awaiting other crucial data this week, including industrial manufacturing numbers tomorrow and key employment figures on Friday. Both releases are widely expected to indicate an economic slowdown in the world's biggest energy-comsuming nation.
