Oil prices extended this week's sell-off on Friday, posting the worst weekly performance in nearly three years, as global oversupply kept buyers away from the market ahead of the long festive break.
U.S. West Texas Intermediate crude oil ended Friday's session down 29 cents at $45.59, the lowest closing price since January 2016. WTI earlier fell to $45.13, its lowest intraday price since mid-July 2017.
Brent crude was down 40 cents at $53.95 per barrel by 2:30 p.m. ET, bouncing from the session's 15½-month low at $52.79. Brent was on pace for a decline of more than 10 percent for the week.
Crude has lost ground along with major equity markets as investors fret about the strength of the global economy heading into next year. Further concerns were raised as the United States, the world's biggest oil consumer, may have a government shutdown later on Friday.
