Iran turned down Oman's proposal for joint control of the Strait of Hormuz, instead repeating demands for more oversight of the waterway, according to media reports on Tuesday.
During a state broadcast Iran's Deputy Foreign Minister Kazem Gharibabadi said that Oman suggested joint 50-50 control of the waterway, with each country controlling shipping lanes closest to their respective coastlines.
On the supply side, data from the American Petroleum Institute revealed Tuesday that US crude oil inventories decreased by 3.3 million barrels in the week ended July 24, according to a Bloomberg-compiled survey.

Meanwhile, OPEC+ is projected to pause further production quota increases after approving a final scheduled hike for September.

"Obviously, supply increases on paper don't necessarily reflect an actual supply increase, given the ongoing supply disruptions in the Persian Gulf. However, post-disruption, the announced supply increases from the group reinforce the view of a well-supplied market through 2027," ING added.
