Crude oil price slumps amid global glut concerns
West Texas Intermediate fell up to 3% after losing 5.7% in the previous three sessions.
Crude supplies rose 8.2 million to the highest level in weekly US government data since 1982.
Harold Hamm, the US shale oil billionaire, had warned this week that the industry could kill the market if it embarks on another spending binge.
The market swoon stoked the second-highest West Texas Intermediate options trading volume ever and sent volatility surging.
Oil had fluctuated above $50 a barrel since the Organisation of Petroleum Exporting Countries and other nations started trimming supply for six months starting in January to reduce a global glut.
While US shale production has rebounded, larger-than-expected cuts elsewhere and signs of growing demand suggest stockpiles will eventually decline, according to Goldman Sachs.
“People are nervous about the global supply-demand balance,” Adam Sieminski, a scholar at the Centre for Strategic and International Studies in Washington and former head of the Energy Information Administration, said.
“Shale is coming back with $50 oil and there’s uncertainty about whether Opec and its partners are going to roll over the production agreement,” he said.
West Texas Intermediate for April delivery dropped 60c, or 1.2%, to $49.68 a barrel on the New York Mercantile Exchange.
Total volume traded was more than double the 100-day average. The contract had fallen 5.4% to $50.28 on Wednesday, the biggest fall since February 2016.
Brent for May settlement was down 56c to $52.55 a barrel on the London-based ICE Futures Europe exchange. Prices fell to $51.60, the lowest since the start of December.
The global benchmark crude traded at a $2.33 premium to May West Texas Intermediate.
