Oil prices rose more than one per cent on Friday, adding to gains in the previous session after OPEC producers and allies promised to meet commitments on cutting supply and two major oil traders said demand was recovering well.
Brent crude LCOc1 futures rose 61 cents, or 1.5 per cent, to $42.12 a barrel by 0639 GMT, the highest in more than a week.
U.S. West Texas Intermediate (WTI) crude CLc1 futures climbed 60 cents, or 1.5 per cent, to $39.44 a barrel.
Both contracts rose about two per cent on Thursday and are heading for weekly gains of nearly nine per cent.
Plans by Iraq and Kazakhstan to make up for overproduction in May on their supply cut commitments supported the market.
The promises came out of a meeting by a panel monitoring compliance by the Organisation of the Petroleum Exporting Countries and its allies, a grouping called OPEC+.
Prices are showing “solidity at these levels, as oil markets ignore the concerns rolling across other asset classes at the moment,” said Jeffrey Halley, senior market analyst at OANDA.
“That suggests that prices are supported by physical buyers (which) is welcome as it implies that physical demand across the globe is recovering, with its implications for economic growth,” he added.
Brent moved into backwardation on Thursday for the first time since early March, with the August contract rising to 9 cents above September LCOc1-LCOc2 on Friday.
Backwardation occurs when near-term contracts are trading at higher prices than outer months, compared with a contango market structure where outer months trade at higher prices.
Fears about dwindling storage capacity had sent the market into steep contango, as wide as $5, as coronavirus lockdowns hit near-term demand and Saudi Arabia and Russia glutted the market with crude in April.
Comments from global oil traders Vitol and Trafigura on a rebound in oil demand in June, reported by Bloomberg, also buoyed the market, ANZ said.
Traders shrugged off another build in U.S. crude inventories to a new record.
Crude stocks USOILC=ECI rose by 1.2 million barrels last week to 539.3 million barrels, compared with expectations from a Reuters poll for a decline of 152,000 barrels.
On the technical side, CMC Markets chief strategist Michael McCarthy pointed to strong resistance in the WTI contract between $40 and $41.
Analysts see that level as the point at which more U.S. producers will revive shut-in wells.
