Deaths from Covid-19 have now topped 150,000 in the United States, while Brazil, with the world’s second-worst outbreak, set daily records of confirmed cases and deaths. New infections in Australia hit a record on Thursday. The potential hit to the demand rebound comes just as the Organization of the Petroleum Exporting Countries (Opec) and its allies, together known as Opec+, are set to step up output in August, adding about 1.5 million barrels per day to global supply.
"The easing Opec+ supply restrictions combined with the return of some US production may test the resilience of market sentiment in the coming weeks," Stephen Innes, chief global market strategist at AxiCorp said.
