Benchmark oil dropped 19 cents to end at $85.38 per barrel in New York. Brent crude, which is used to price international varieties of oil, fell 81 cents to $108.26 per barrel in London.
The Paris-based agency lowered its forecast for fourth-quarter oil demand by 300,000 barrels per day to 90.1 million barrels. Its forecast for 2013 dropped 100,000 barrels per day to 90.4 million barrels per day.
Meanwhile, global oil supplies increased 800,000 barrels per day to 90.9 million barrels per day in October, the agency said.
The IEA blamed the weak European economy for slowing demand for oil and energy products. Another factor in lower fourth-quarter demand is Hurricane Sandy, which disrupted oil imports and gasoline deliveries on the
East Coast, the agency said.
