Getty Images Oil prices plunged on Wednesday, with futures falling to their lowest since January, after the U.S. government reported an unexpected surge in the nation's crude stockpiles. U.S. commercial crude inventories jumped by 6.8 million barrels in the week through May 31, the U.S. Energy Information Administration reported. Stockpiles jumped despite refineries increasing activity and as U.S. crude imports jumped by more than 1 million barrels per day. That trumped an earlier reading from the American Petroleum Institute that suggested stockpiles rose by 3.5 million barrels in the week. Analysts' had expected stocks to drop by 849,000 barrels, according to a Reuters poll. U.S. West Texas Intermediate crude fell to a session low of $50.66 after the report, the lowest level since Jan. 15. WTI settled $1.80 lower at $51.68 a barrel, falling 3.4% to its weakest closing price in nearly five months. Brent futures sank as low as $59.45, also its lowest since mid-January. Brent was down $1.31, or 2.1%, at $60.66 a barrel around 2:25 p.m. ET (1825 GMT). U.S. gasoline inventories also rose by 3.2 million barrels during the week. Stockpiles of distillates, including diesel and home heating fuel, jumped by 4.6 million barrels. Meanwhile, weekly U.S. oil production ticked up to an all-time high 12.4 million bpd, according to a preliminary reading from EIA. "You had that record U.S. production again and that surge in imports really just overwhelmed the report, and it came in the face of refinery runs ticking up," said John Kilduff, founding partner at energy hedge fund Again Capital. "Obviously it's more than enough to satisfy demand by a lot and just makes for a really bearish report across the board." The stockpiles report compounded pressure on oil prices, which swiftly collapsed over the last week as the market braced for a prolonged trade battle between the U.S. and China. President Donald Trump's threat last week to slap tariffs on Mexican goods, exacerbating fears that global economic growth will slow and cut demand fuel. Crude futures clawed back some gains on Tuesday as the stock market bounced on hopes the Federal Reserve will cut interest rates. Equities continued to rally on Wednesday, putting a floor under crude prices earlier in the day. "Really $50 is legitimate support zone [for WTI] because we had a hard time getting up and through that on the rally through December," Kilduff said. "So that's going to be the next level to watch." The rise in U.S. stockpiles and fresh leg lower for crude prices comes as OPEC and its oil market allies are preparing to meet to decide production policy in the coming weeks. The so-called OPEC+ alliance has been withholding supply since the start of the year in order to drain oversupply and prop up prices. Saudi Arabia's powerful energy minister has signaled that the group is leaning towards extending output caps into the second half of the year. However, Russia's oil companies have begun to chafe under the quotas. Igor Sechin, CEO and chairman of Russian energy giant Rosneft, this week said Russia should be free to hike output and floated the idea of seeking compensation if Moscow agrees to roll over the production deal. Russia is pitching in the biggest cuts among non-OPEC producers in the alliance.
Oil prices fell amid fears of slowing global growth due to the trade war and US President Donald Trump's threats of tariffs against Mexico. In addition, US crude inventories rose by 3.5 million barrels to 12.4 million in the week to 31 May, compared to an anticipated fall of 849,000 barrels. The figures came as the Organization of the Petroleum Exporting Countries and Russia will decide in the coming weeks whether to end supply curbs, as Igor Sechin, head of Rosneft, questioned why Russia should reduce output only for the US to grab its market share.
