Oil edges lower as supply concerns return

Tokyo: Oil prices edged lower on Friday after strong gains the previous day, easing on persistent supply concerns as Russia increased production in July and Saudi Arabia cut the price of crude for its Asian customers.

Brent crude futures LCOc1 were down 13 cents, or 0.2 per cent at $73.32 a barrel by 0052 GMT, after rising 1.5 per cent on Thursday.

US crude CLc1 was off by 5 cents at $68.91, after gaining nearly 2 per cent in the previous session.

Russian oil output rose by 150,000 barrels per day in July from a month earlier, surpassing the amount Moscow had said ti would add following a meeting of global oil producers in Vienna in June, energy ministry data showed on Thursday.

Saudi Arabia, Russia, Kuwait and the United Arab Emirates have increased production to help to compensate for an anticipated shortfall in Iranian crude supplies once planned US sanctions take effect later this year.

The Organization of the Petroleum Exporting Countries and partners including Russia had earlier cut output to rebalance supply and demand.

Saudi Aramco cut its September price for its Arab Light grade for Asian customers by $0.70 a barrel versus August to a premium of $1.20 a barrel to the Oman/Dubai average, it said on Thursday.

Oil prices tanked earlier this week when the US government reported that US inventories rose 3.8 million barrels in the prior week, against expectations, but rose on Thursday on expectations the stockpile would soon decline again.
