Oil futures fell further on Wednesday after big declines the previous session with Brent sliding below $40 a barrel for the first time since June as covid-19 cases rebounded in several countries.
The biggest global health crisis in a century continues to flare unabated with cases rising in India, Great Britain, Spain and several parts of the United States, where the infection rate has not come under control for months.
Brent crude was down 16 cents, or 0.4%, at $39.62 a barrel by 0241 GMT after declining more than 5% on Tuesday.
US crude was down 24 cents, or 0.7%, at $36.52 a barrel, having fallen nearly 8% in the previous session.
Record supply cuts by the Organization of the Petroleum Exporting Countries and allies, known as OPEC+ have helped support prices, but with grim economic figures being reported almost daily, the outlook for demand for oil remains bleak.
