West Texas Intermediate crude declined, widening its discount against Brent to the most in five weeks on estimates that oil stockpiles increased last week in the United States, the world’s largest user of the commodity.
WTI futures dropped as much as 0.5 percent in New York after falling the most since Jan. 2 Tuesday.
U.S. crude stockpiles probably rose for the 13th time in 14 weeks, a Bloomberg News survey shows before government data Wednesday.
Prices also slipped on signs of a manufacturing slowdown in China, the second-biggest oil consumer. Brent was steady on concern that the clash over Ukraine between the West and Russia, the world’s largest crude producer, may intensify.
“Growth is slowing globally and we expect the market to soften over the summer,” Guy Wolf, global head of market analytics at Marex Spectron Group in London, said by email. China’s “economy is slowing as part of a deliberate tightening strategy,” he said.

A preliminary China Purchasing Managers’ Index from HSBC Holdings Plc (NYSE: HSBC)and Markit Economics was at 48.3 for April, signaling a fourth month of contraction.
Wednesday’s figure matched the median projection of economists in a separate Bloomberg survey. Readings below 50 signal contraction.
WTI dropped 0.5 percent in the week ended April 4, the first decline in three weeks, after HSBC and Markit reported a final manufacturing index of 48 for March on April 1.
China will account for about 11 percent of global oil consumption this year, compared with 21 percent for the United States, estimates from the International Energy Agency in Paris show.
The Chinese PMI “has been below 50 since the beginning of the year, signaling contraction rather than growth in the Chinese manufacturing sector,” Michael Poulsen, an analyst at Global Risk Management Ltd. in Middelfart, Denmark, said in a report. “Tensions in Ukraine are still building.”
U.S. crude inventories probably expanded by 3 million barrels in the week ended April 18, according to the median estimate of 10 analysts surveyed before data from the Energy Information Administration, the Energy Department’s statistical arm.
