Oil Markets Rebalance as US Output Hits Record High

A Market in Transition

Global oil markets are working through one of the most consequential supply shocks in years, as fallout from the U.S.-Israel conflict with Iran continues to ripple through production, trade, and pricing. The U.S. Energy Information Administration's Short-Term Energy Outlook projects that it could take until early 2027 before production and trade patterns in the Persian Gulf fully normalize, with some regional producers unlikely to ever return to pre-conflict output averages during the forecast window 1.

Hormuz Disruptions Reshape Supply

The scale of the disruption has been dramatic. The International Energy Agency's March 2026 Oil Market Report finds that crude and product flows through the Strait of Hormuz have collapsed from roughly 20 million barrels per day before the war to a mere trickle, with little spare capacity available to reroute shipments and storage capacity filling up fast 8. As a result, Gulf producers have slashed total output by at least 10 million barrels per day, and the IEA projects global supply could fall by as much as 8 million barrels per day in March, a decline only partially cushioned by rising output from non-OPEC+ producers such as Kazakhstan and Russia 8.

OPEC+ Responds With Incremental Increases

Against this backdrop, OPEC+ has moved cautiously to add barrels back into the market. A coalition of seven members, including Saudi Arabia and Russia, agreed to raise combined production by 188,000 barrels per day, a step characterized across multiple reports as a modest but meaningful signal that the alliance sees room for recovery even as Hormuz-related risks persist 2467. That figure is notably smaller than the 206,000 barrels-per-day increase approved the previous month, underscoring OPEC+'s deliberate, measured approach rather than a rush to flood the market 7. The decision also marked the group's first meeting following the departure of the United Arab Emirates as a key member, adding a layer of internal recalibration to the group's supply strategy 7. Separately, Iraq has signaled ambitions to more than double its own output within six years, targeting 8 to 10 million barrels per day, though it first needs OPEC's blessing to pursue such an expansion 5.

US Production Sets a New Record

While Gulf supply has been constrained, American producers have moved in the opposite direction. U.S. crude output climbed 3%, or 350,000 barrels per day, in 2025, pushing the annual average to a record 13.6 million barrels per day 3. The Lower 48 states, excluding the Gulf of America, accounted for the bulk of that growth, contributing 11.3 million barrels per day, or 83% of total national production 3.

Why It Matters

Taken together, the coverage paints a picture of a market rebalancing along two tracks: a Middle East grappling with war-driven supply losses and a slow path back to normalcy, and a U.S. industry setting records that help offset global shortfalls. The interplay between OPEC+'s cautious output additions, Iraq's expansion ambitions, and record American production will likely shape crude prices and, by extension, gasoline prices at the pump in the months ahead.
