OPEC+ approved a fourth increase in oil output quotas on Sunday to offset supply disruptions caused by the ongoing U.S.–Iran war [1], [2].

The decision comes as the closure of the Strait of Hormuz continues to block critical shipping lanes and disrupt Gulf oil production. By increasing the collective target, the organization aims to stabilize global energy markets and prevent extreme price volatility during the conflict.

The group agreed to raise the collective production target by 188,000 barrels per day [3], [4]. This adjustment is scheduled to take effect starting in July [3].

This marks the fourth consecutive monthly quota hike since the Hormuz closure [1], [5]. The ongoing military conflict between the U.S. and Iran has fundamentally altered the flow of crude oil, forcing the alliance to adjust targets more frequently to fill the gap left by blocked Iranian and regional exports [2], [4].

While some reports previously suggested a third hike in May, verified data confirms this is the fourth increase agreed upon as of June 7 [1], [5]. The alliance continues to monitor the security situation in the Gulf to determine if further adjustments are necessary to maintain global supply levels [2].

“OPEC+ approved a fourth increase in oil output quotas on Sunday”

The repeated quota increases signal that OPEC+ is struggling to fully compensate for the loss of Gulf production caused by the U.S.–Iran conflict. While 188,000 barrels per day provides a marginal boost, the necessity of four consecutive hikes suggests that the closure of the Strait of Hormuz is creating a persistent supply deficit that cannot be solved by a single policy shift.
