LONDON: Oil prices edged higher on Friday but were on track for their first weekly fall in seven as new US coronavirus cases spiked, raising the prospect of a second wave hitting demand.

Brent was up 20 cents, or 0.52pc, at $38.75 a barrel by 0926 GMT, having lost more than $1 earlier in the session.

After falling more than 5pc on Friday, West Texas Intermediate was up 15 cents, or 0.41pc to $36.49 a barrel. Both contracts ended around 8pc lower on Thursday.

The oil benchmarks are heading for weekly declines of more than 8pc, their first after six weeks of gains which have lifted them off their April lows.

Fears that the coronavirus pandemic may be far from over has brought the rally to a halt, with about half a dozen US states seeing a spike in new infections.

Barclays on Friday raised its oil price forecasts for this year by $4 per barrel, citing a bigger deficit in the second half of the year, although it expressed caution on a slow recovery in the near term.

"The rate of change in fundamentals is likely to moderate significantly as incremental demand improvement will depend more on consumer behaviour than the easing of enforced movement restrictions," the British bank said in a note.

Producers from the United States, as well as from the Organization of the Petroleum Exporting Countries (OPEC) and its allies, a group known as OPEC+, have been cutting supply.

OPEC+ cut oil supplies by 9.7 million barrels per day (bpd), about 10pc of pre-pandemic demand, and agreed last weekend to extend the reduction.

US crude and gasoline stockpiles grew last week, government data showed. US crude inventories hit a record 538.1 million barrels, as cheap imports from Saudi Arabia flowed into the country.
