The price for oil produced by the Organization of the Petroleum Exporting Countries (OPEC) inched up by 0.77 dollars Thursday but stayed in the 40-dollar-range, as analysts said Friday that output cuts were leading to a more balanced market, dpa reported. One barrel (159 litres) of OPEC-produced crude stood at 40.31 dollars Thursday, the Vienna-based cartel announced Friday. OPEC's basket price of 12 crude brands has remained in a range of around 39 to 42 dollars since January 8. The price situation was related to the cartel's decisions to slash output by a total of 4.2 million barrels per day since last September in reaction to lower demand, said Carsten Fritsch, a commodity analyst at Commerzbank in Frankfurt. "There are indications that the cuts decided in December are being implemented," in addition to the lower production rates agreed to earlier in the autumn, Fritsch said.
