Crude oil prices declined more than 2% on Thursday pressured by an increase in US crude stockpiles and gloomy demand outlooks from OPEC and the IEA.
The Brent crude futures contract dipped 2.5% to $86.74 per barrel, while West Texas Intermediate crude futures declined 2.7% to $81/bbl.
"Oil prices did come under pressure after the US Energy Information Administration reported that US crude oil inventories rose by 17.4 mbbl last week," ANZ analysts noted.
US commercial crude oil inventories increased by 17.4 million barrels to 424.4 mmbbls in the week ended Aug. 7, the Energy Information Administration said in its weekly report on Wednesday.
