(Bloomberg) -- Oil is poised for its biggest weekly advance since early June with Saudi Arabia ratcheting up the pressure on OPEC+ members to adhere to the group’s production cuts amid signs demand is faltering.Futures in New York are up almost 11% this week, despite bearish calls on the outlook from industry heavyweights such as BP Plc and Trafigura Group to the International Energy Administration. Saudi Arabia showed its determination to protect the recovery at an OPEC+ committee meeting on Thursday, lambasting members that have cheated on production quotas.Oil has clawed its way back to $41 a barrel this week, buoyed by a weaker dollar and a surprise decline in U.S. crude inventories. The market is still contending with an uneven recovery in consumption, with OPEC+ seeing a risk to demand from a second wave of the outbreak, urging members to be proactive and ready to take further action.“Saudi Arabia’s stern warning added to investor confidence after the unexpected decline in American inventories led to a price rally this week,” Will Sungchil Yun, a senior commodities analyst at VI Investment Corp, said by phone from Seoul. “But this may be temporary since we need a strong and consistent signal that a real demand recovery is actually happening.”See also: Covid-19 Has Sidelined Enough Fuel to Power a Million PickupsSaudi Energy Minister Prince Abdulaziz bin Salman opened the meeting with a forceful condemnation of members that try and get away with pumping too much crude.
