"Crude oil prices are notoriously fickle when it comes to oscillations in global sentiment," said Dimitri Zabelin, analyst at DailyFXOil prices eased on Friday, reversing earlier gains, as the resurgence of the coronavirus globally and in the United States, the world's largest oil consumer, stoked worries that a fuel demand recovery could stall. Brent crude futures were down 29 cents, or 0.7 per cent, at $42.85 a barrel as of 0339 GMT, and US West Texas Intermediate (WTI) crude futures fell 31 cents, or 0.8 per cent, to $40.34 a barrel.
Both benchmarks rose more than 2 on Thursday, buoyed by stronger-than-expected U.S. jobs data and a fall in US crude inventories. For the week, Brent is up 4.4 per cent and WTI is up 4.8 per cent. Increases in the daily cases of the coronavirus, however, globally and in the United States pressured prices. New US COVID-19 cases rose by more than 50,000 on Thursday, setting a record for a third consecutive day, according to a Reuters tally.
