Weak economic data led to the further downfall of oil prices on Thursday. Also larger than expected rise in US crude inventories had an adverse effect on the fuel demand outlook. Brent went down by 0.3% and was traded at $57.52 a barrel. WTI went down by 0.2% and was traded at $52.55 a barrel. EIA on Wednesday informed about the 3.1 million barrels rise in US crude inventories.
