Oil sank to six-month lows on Monday with Brent crude falling below $50 a barrel on sluggish U.S. and Chinese economic data and bets for weaker gasoline consumption in the United States after tearaway demand earlier in the summer.
U.S. crude slid $1.95, or 4 percent to settle at $45.17 a barrel, marking its largest loss in nearly a month. Brent crude oil was last down $2.80 to $49.40 a barrel earlier in the day, its weakest since Jan. 30.
Evidence of growing global oversupply and a stock market collapse in China, the world’s largest energy consumer, have weighed on oil for weeks, leading in July to U.S. crude futures’ largest monthly decline since the 2008 financial crisis.
With August trading in its first session, the rout accelerated as gasoline prices fell more than that of crude.
Supply worries aside, traders pinned the latest losses on sluggish U.S. and Chinese data.
U.S. consumer spending advanced at its slowest pace in four months in June as demand for automobiles softened. Growth in Chinese manufacturing activity, meanwhile, unexpectedly stalled in July as demand at home and abroad weakened.
“Economic weakness has set the tone,” said Matt Smith, director of commodity research at Clipperdata, a New York-based energy database.
“But the gasoline crack spread is also unravelling,” Smith said, referring to the difference between gasoline and U.S. crude prices, which sets the profit margin for refiners.
“The chart is looking anything but constructive,” said Fawad Razaqzada, technical analyst in London for forex.com, who expects U.S. crude to test its March low of $42.03 and Brent its January bottom of $45.19.
Gasoline was down 5 percent, narrowing its crack, or spread, with U.S. crude to below $26, the lowest in more than a week.
A Reuters survey last week showed oil output by the Organization of the Petroleum Exporting Countries (OPEC) reached the highest monthly level in recent history in July.
The survey showed Saudi Arabia and other key OPEC members keen to defend market over crude prices, which are down 12 percent this year, after last year’s 48 percent tumble.
Hedge funds and other speculators have cut their bullish exposure to U.S. crude to a near 5-year low, trade data showed on Friday, as local drillers added rigs and pumped at full throttle despite the global oil glut.
Large investors in Brent also cut their holdings last week by the most in percentage terms since September 2014.
