Bulls see oil demand recovering further from the pandemic this year, with supply falling short due to recent weak upstream investment. The prevailing belief is that this will expose Opec-plus spare capacity as an empty shell, possibly paving the way for a new supercycle in oil. Energy Intelligence now puts Opec-plus spare capacity at less than 3.5 million barrels per day. But if the group follows its agreement and adds 400,000 b/d through September, only Saudi Arabia and the United Arab Emirates would be left with any substantial spare capacity, with a trickle remaining in Kazakhstan and Oman. All told, this would amount to a precarious 1 million b/d. The market does not believe Opec-plus can reach its goal of producing 43.7 million b/d by September — the total of the output targets for its 20 producers, including Mexico but excluding Iran, Libya and Venezuela, per the current agreement. A driving force behind Brent’s recent strength is that an increasing number of Opec-plus producers are already falling short of allotments, a situation that will become more visible in the coming months if the group continues to unwind more cuts. Nigeria, Angola and Malaysia are already far behind, leaving Opec-plus output 700,000 b/d short of its December goal.
