In February, OPEC called for an oil production “freeze” to raise crude prices in conjunction with Russia. But this effort collapsed at a meeting in Doha, Qatar, in April when Iran refused to join any freeze in order to regain the pre-2012 production levels of close to 4 mbpd it enjoyed before U.S. and European Union nuclear sanctions were imposed, following the removal of certain sanctions after the 2015 nuclear deal. A similar proposal failed at the OPEC meeting in June, again following Iran’s refusal, despite outreach by the Qataris.
