NEW YORK — The price of oil closed at a six-week low as the catalysts that drove it above $110 earlier this month lost strength.
Meanwhile, pump prices in the U.S. are the lowest since early July, and experts say they're likely headed lower.
Benchmark oil for November delivery fell $1.16, or 1.1 percent, to close at $103.59 on the New York Mercantile Exchange. Oil has dropped 6.3 percent since closing at a two-year high of $110.53 on Sept. 6.
Analysts said the apparent progress being made in the elimination of Syria's chemical weapons, a seeming thaw in relations between Iran and Western powers and the return to markets of crude from Libya and South Sudan were weighing on oil prices.
In the U.S., the average price for a gallon of gasoline fell over the weekend to $3.47. That's the lowest level since July 8, and is 34 cents cheaper than at this time last year.
The price-watching site GasBuddy.com expects the price of gas to fall further as refineries produce ample amounts of fuel while demand remains about where it was a year ago.
Brent crude, the benchmark for international crudes used by many U.S. refineries, dropped $1.06 to $108.16 a barrel on the ICE Futures exchange in London.
