Oil prices were mixed Wednesday, reversing strong gains after data showed U.S. crude stockpiles jumped unexpectedly in their largest build since April amid a record surge in imports.
U.S. crude inventories rose by 15.2 million barrels to 503.2 million barrels last week, according to the Energy Information Administration, compared with analysts’ expectations in a Reuters poll for a 1.4 million-barrel drop..
“I’m trying to get my jaw off the ground here...15 million barrels is an off-the-charts build,” said Phil Flynn, senior analyst at Price Futures Group in Chicago.
U.S. net imports of crude oil rose by 2.7 million barrels per day last week, the biggest increase on record, as exports plunged.
“It looks like the Saudis are targeting the U.S. inventories situation again, sending barrels here,” said John Kilduff, partner at Again Capital LLC in New York.
U.S. gasoline and distillate stockpiles were also markedly higher as refineries boosted output.
“The significant increase in gasoline and distillate inventories is likely a result of lower oil demand post the Thanksgiving holiday, as well as additional stay at home measures across country,” said Andrew Lipow, president of Lipow Oil Associates in Houston.
