Brent crude oil fell to a more than four-year low near $82 a barrel on Tuesday, after top oil exporter Saudi Arabia cut sales prices to the United States.
Front-month Brent crude touched a low of $82.08, its weakest since October 2010, and was down $2.10 at $82.68 a barrel by 1030 GMT.
U.S. December crude was down $2.20 at $76.58 a barrel. It touched a session low of $75.84, its weakest since October 2011, as its discount to Brent hovered around $6.
The Brent price plunged more than 50 cents below last month’s low of $82.60 before recovering.
“We’ve been seeing some technical stop loss selling because the price has reached new lows,” said Christopher Bellew, a broker at Jefferies in London.
The world’s top exporter increased its December sales prices, relative to benchmarks, to Asia and Europe on Monday, but lowered prices to the United States, a smaller export market.
“This is mixed news, and the fact that the positive angle has not made an impact shows that market sentiment is very negative at the moment,” said Eugen Weinberg, head of commodities research at Commerzbank in Frankfurt.
