OPEC’s oil production rebounded notably in June, climbing by over three million barrels per day from May as Gulf oil producers began reactivating previously shut wells after months of conflict-related outages. This increase brought the cartel’s total output to just below 19.5 million barrels per day. However, this recovery still falls short of pre-crisis norms in the Middle East, where supply disruptions persist.
The biggest contributors to the surge were Kuwait and Iran. Iran regained production capacity after the United States lifted its naval blockade on its ports under a temporary 60-day agreement, allowing exports to resume. At the same time, Gulf producers gradually restarted wells that had been idled as storage tanks filled up and tanker movements through the Strait of Hormuz were severely restricted. Saudi Arabia and Iraq also increased their output, while Nigeria and Libya reported smaller gains despite not suffering the same level of disruption during the conflict.
Despite this sharp increase, OPEC’s collective output remains under their official quota limits. Much of the recent boost is attributable to the return of volumes previously taken offline rather than genuine expansion of supply. Crucially, tanker traffic through the Strait of Hormuz, a key transit route, continues at levels much lower than before the war, with insurers and shipping companies remaining cautious following repeated attacks on commercial vessels in the area.
This ongoing bottleneck helps explain why OPEC+’s repeated quota hikes have yet to translate into proportional increases in market supply. The cartel has announced multiple increases in production limits since the onset of the Iran war, but export constraints and limited transport capacity have prevented these increments from materializing fully.
Adding pressure to the global oil market, recent data shows record-high crude production in the United States, approaching 14 million barrels per day. At the same time, the United Arab Emirates, now outside OPEC, is exporting record volumes as it draws down storage accumulated during the conflict. These developments have fueled renewed concerns about oversupply and exert downward pressure on crude prices despite geopolitical tensions.
