Oil slumps 3 percent on OPEC supply, China's tariffs

Oil prices fell more than $2 a barrel Friday after two of the world’s biggest producers indicated they might increase output at next week’s OPEC meeting, while U.S. exports were threatened by potential Chinese tariffs on crude oil and refined products.

Oil investors have been nervous ahead of the coming OPEC summit in Vienna. Saudi Arabia and Russia have already boosted production modestly, and have indicated they were prepared to increase output at that meeting.

Brent crude oil LCOc1 fell $2.50, or 3.29 percent to settle at $73.44 a barrel. U.S. crude CLc1 settled $1.83 lower at $65.06 a barrel. In post-settlement trading, U.S. crude retreated further, falling 2.25, or 3.4 percent, to $64.64 a barrel.

Brent crude was on track to end the week down more than 4 percent, while U.S. crude was heading to fall 1.7 percent.

After settlement, China announced $50 billion in retaliatory tariffs, in response to a series of levies by U.S. President Donald Trump earlier.

Some investors were surprised when crude oil and other energy products were included for tariffs at a later date, the official Xinhua news agency reported, citing the Tariff Commission of the State Council.
