OPEC+ Hikes May Output by 206,000 BPD, but 230 Loaded Tankers Remain Stranded in Persian Gulf

The eight nations of OPEC+ agreed April 5 to lift combined oil production by 206,000 barrels per day (bpd) in May 2026, continuing the incremental unwinding of voluntary supply cuts first announced in April 2023. But with roughly 230 loaded crude tankers sitting inside the Persian Gulf unable to transit the Strait of Hormuz, the production increase is widely viewed as a paper exercise until shipping lanes fully reopen.

Who Produces What in May

Saudi Aramco's parent nation Saudi Arabia carries the largest allocation in the May hike, adding 62,000 bpd to bring its required output to 10.228 million bpd. Russia also adds 62,000 bpd, targeting 9.699 million bpd. Iraq follows with a 26,000 bpd increase to 4.326 million bpd, the UAE adds 18,000 bpd to 3.447 million bpd, and Kuwait contributes 16,000 bpd to reach 2.612 million bpd. Smaller producers Kazakhstan, Algeria, and Oman add 10,000, 6,000, and 5,000 bpd respectively.

The group formally described the decision as part of a production adjustment of 206,000 barrels per day from the 1.65 million barrels per day additional voluntary adjustments announced in April 2023. The coalition is unwinding earlier cuts in measured monthly tranches rather than a single reversal, maintaining flexibility to pause or reverse the phase-out depending on market conditions. The next monitoring meeting is scheduled for May 3, 2026.

The Hormuz Problem

What makes the May hike almost symbolic in physical market terms is the state of the Strait of Hormuz. Following the late-February airstrikes on Iranian oil infrastructure and retaliatory closures, the strait, through which roughly 10 million bpd normally flows, has been largely impassable for commercial shipping. A ceasefire was declared April 8, but tanker traffic has not recovered to pre-conflict levels as of mid-April 2026.

Shipping data show approximately 230 fully loaded crude tankers stranded inside the Gulf, unable to clear the Hormuz chokepoint. Most of those vessels carry Saudi, Iraqi, Kuwaiti, and UAE crude destined for Asian refiners. The backlog represents more than two full weeks of normal Gulf export volume.

At 206,000 bpd, the OPEC+ production increase represents less than 2 percent of the 10 million bpd supply disruption. Even if all May quota barrels are physically produced and loaded, the global deficit remains overwhelming. The IEA April oil market report projected that global supply fell 10.1 million bpd to 97 million bpd in March, the largest single-month supply shock since the 1970s oil embargo.

Price Context: Brent, WTI, and WCS

Benchmark crude prices have eased from their crisis peaks but remain highly elevated. Brent crude is trading near $94.89 per barrel as of April 16, while West Texas Intermediate (WTI) sits in the $90.54 to $93.00 range. Both benchmarks briefly spiked above $120 per barrel in late March when the conflict was most acute, and climbed back above $103 per barrel on April 13 after the US announced a naval blockade of Iranian ports.

For Canadian producers, Western Canadian Select (WCS) remains at a meaningful differential below WTI, currently around $16 per barrel based on recent pipeline data, translating to roughly C$100 to C$105 per barrel for Alberta oil sands producers. That is still a historically strong netback, though the wide differential reflects ongoing Trans Mountain pipeline commissioning dynamics. OPEC's own April monthly report flagged that Iraq's crude output fell 61 percent in March, illustrating just how severely Gulf producers are suffering through their own production crisis even as prices surge.

What Happens at the May 3 Meeting

That meeting will determine whether June production levels follow the same 206,000 bpd increment, accelerate the drawdown of voluntary cuts, or pause entirely in response to Hormuz conditions. Analysts at TotalEnergies and other major integrated companies have noted that the market reaction to the May hike was muted precisely because physical deliveries depend on the Hormuz timeline, not OPEC+ quotas. Until loaded tankers begin moving again at scale, the production decision carries more political than commercial significance.

For markets watching both global oil supply and Canadian crude pricing, the critical variable is not how many barrels OPEC+ has authorized on paper, but how quickly the strait reopens to commercial traffic. That decision belongs to governments and navies, not quota tables in Vienna.
