歐佩克參考籃子在12月進一步上升，在$ 85-90 / b的范圍內(nèi)波動，每月平均為$ 85.56 / b。 上升趨勢歸因于宏觀經(jīng)濟預(yù)期的改善和北半球冬季寒冷的推動，市場氣氛樂觀。 美國庫存的下降以及對石油等大宗商品投資需求的增長也支撐了價格。 12月，Nymex WTI前月均價為$ 89.23 / b，ICE布倫特均價為$ 92.65 / b。 1月初，期貨價格繼續(xù)上漲，達到了27個月以來的新高，布倫特原油價格約為98美元/桶。 在這一年中，該籃子在2010年的平均價格為77.45美元/桶，比上年增長26.8％。 1月份籃子價格上漲，1月14日達到$ 94.04 / b。
