據市場觀察網站9月11日消息：周五，石油期貨本周收盤下跌逾6%，而美國油價當天幾乎沒有變化。交易商繼續擔憂能源需求前景，以及美國原油周供應量，這增加了市場供應過剩的可能性。紐約商品交易所10月份西德克薩斯中質原油期貨CLV20上漲3美分，收于每桶37.33美元，漲幅0.08%。道瓊斯市場數據顯示，當月合約價格本周下跌6.1%。

Oil futures lose more than 6% for the week

Oil futures ended the week with a loss of more than 6% on Friday, with U.S. prices little changed for the session. Traders continued to fret over the outlook for energy demand, as well as a weekly increase in U.S. crude supplies, which raised the potential for an oversupplied market. October West Texas Intermediate oil CLV20, +0.16% rose 3 cents, or 0.08%, to settle at $37.33 a barrel on the New York Mercantile Exchange. Prices for the front-month contract lost 6.1% for the week, according to Dow Jones Market Data.
