• Iraq's oil production faces a drastic cut exceeding 3 million barrels per day within days if tankers cannot access southern loading ports due to the Strait of Hormuz blockade.
  • Brent crude surged 13% to $82 per barrel, with global supply disruptions risking prices hitting $100–110 per barrel and forcing Chinese refinery cuts.
  • The crisis stems from U.S.-Israeli airstrikes on Iran, triggering regional shutdowns and stranding OPEC+ barrels despite intact fields.

Iraq will be forced to slash its oil production by more than 3 million barrels per day in a matter of days if tankers remain unable to move freely and reach loading ports, according to two Iraqi oil officials familiar with the matter. The dire warning comes as Iran's Revolutionary Guard Corps has suspended vessel passage through the Strait of Hormuz since February 28, 2026, following U.S.-Israeli airstrikes that killed Iran's Supreme Leader Ali Khamenei, leading to halted tanker movements, attacks on ships, and shutdowns of oil and gas facilities across the region.

Efforts to maintain exports have hit a snag, with Iraq's airspace closed amid threats from Iran-aligned Shia militias against U.S. targets, complicating logistics. "Without a deal to reopen the strait, the company would be forced into bankruptcy," one official said, referring to the broader economic strain on producers. The blockade has left Iraq's fields, including Kirkuk and Basra, intact but logistically choked, stranding its oil exports despite production capacity.

Brent crude surged 13% to $82 per barrel as of early March 2026, with West Texas Intermediate hitting $75.33 per barrel, as the Strait handles over 20% of global seaborne oil—more than 20 million barrels per day of crude, condensate, and LNG. Extreme scenarios now risk prices spiking to $100–110 per barrel, inflating global fuel prices and contributing to economic slowdowns. Analysts warn that Chinese refiners could face 10–25% production cuts by May–June due to feedstock shortages, adding to procurement anxiety that's driving front-loading of inventories.

In a related development, OPEC+—including Iraq, Saudi Arabia, the UAE, and Kuwait—had agreed to a 206,000 barrel per day hike starting in April, but analysts deem it insufficient against Hormuz disruptions. Rystad Energy noted the increase is "unlikely to calm markets," with attention focused on Hormuz reopening versus further escalation. The crisis has created a "double-blockade" for Middle East exports, compounded by ongoing Red Sea issues, with freight costs rising 40–60% via Cape rerouting and lead times doubling to 8–12 weeks for lubricants and additives.

Regional shutdowns have escalated, with Qatar declaring force majeure on LNG exports (20% of global exports), Saudi Arabia's largest refinery halted, and Israel and Iraq implementing partial gas and oil cuts. Over 150 ships are stranded, and one seafarer was killed in attacks, according to people briefed on the incidents. Limited bypasses, such as Saudi Arabia's East-West pipeline (handling 2–4 million barrels per day) and the UAE's Fujairah port (0.4–0.5 million barrels per day), cover less than 25% of the strait's throughput, heightening global tensions.

Base oil markets are tightening, with Group II prices up 15–20%, and lubricant buyers, including hydraulic oil users, are urged to stockpile amid additive shortages like calcium sulfonate greases and EP packages. In the short term, tanker shortages could force production cuts not only in Iraq but also in Saudi Arabia, the UAE, Kuwait, and Iran within days if new vessels cannot be deployed. Iran is assessing its missile and drone stocks, with the Hormuz closure persisting into its fourth day by early March.

Longer-term, a base scenario of partial restrictions in the second quarter risks base oil price spikes by July, with a tail risk of broader war impacting Saudi and UAE capacity. Prior OPEC+ cuts, which were phasing out through 2026, are now irrelevant amid the conflict, according to market observers. Attempts to reach Iraqi energy ministry officials for further comment were unsuccessful, but sources indicate that without a resolution, the situation could worsen rapidly, forcing unprecedented shut-ins across the region.

Correction: An earlier version misstated the timeline for Chinese refinery cuts; they are projected for May–June, not immediately.
