Oil prices at $100 a barrel look too high for global demand to sustain

• Oil's price surge last month has pushed down consumer demand, the International Energy Agency said.
• As Brent crude oil prices neared $100 a barrel, gasoline deliveries fell to two-decade lows.
• The IEA said that pointed to evidence of demand destruction.

Crude oil's rise toward $100 a barrel last month cracked global demand, the International Energy Agency said in a new report.

After OPEC's production cuts sent Brent crude above $97 a barrel at September's end, data indicated that may have been too high.
