Oil fell below US$43 a barrel on Friday as a resurgence of coronavirus cases raised concern that fuel demand growth could stall, although crude was still headed for a weekly gain on lower supply and wider signs of economic recovery.
The United States reported more than 55,000 new coronavirus cases on Thursday, a new daily global record for the pandemic. The rise in cases suggested US jobs growth, which jumped in June, could suffer a setback.
Brent crude was down 52 cents, or 1.2 percent, at US$42.62 a barrel as of 0805 GMT, and US West Texas Intermediate (WTI) crude fell 50 cents, or 1.2 percent, to US$40.15.
“The fragile US economic rebound is at risk of being undone by the latest surge in new infections,” said Stephen Brennock of oil broker PVM.
Both benchmarks rose more than 2 percent on Thursday, buoyed by strong US June jobs figures and a drop in US crude inventories. Brent is still heading for a weekly gain of more than 5 percent.
Signs of economic recovery, and a drop in supply after a record supply cut by the Organization of the Petroleum Exporting Countries and allies, known as OPEC+, have helped Brent more than double from a 21-year low below $16 reached in April.
Boosting recovery hopes, a private survey showed on Friday that China’s services sector expanded at the fastest pace in over a decade in June.
OPEC oil production fell to its lowest in decades in June and Russian production has dropped near its OPEC+ target.
The bankruptcy filing of US shale pioneer Chesapeake Energy also supported prices by raising expectations production will decline, JBC Energy said in a report.
Gasoline demand will be closely watched as the United States heads into the July 4 holiday weekend. US gasoline stocks rose by 1.2 million barrels last week.
