Hormuz Mine Clearance and Tanker Insurance Set Six-Month Floor on Gulf Oil Supply Recovery

WTI crude fell to $75.78 per barrel on Monday, down 5.93% on the day, per TradingEconomics. That is the benchmark's lowest level since early March 2026, when the US-Iran war disrupted Persian Gulf shipping. Brent crude stood at $81.55 per barrel as of 8:30 AM Eastern, per Fortune, having fallen from $111.91 just one month earlier. The peace deal between the United States and Iran, with formal signing expected Monday in Switzerland, has driven the 27.1% decline from that peak. The five analyst firms that study Gulf shipping logistics project sharply different pictures of when physical supply will actually normalize.

Five Firms, Five Timelines

Published before the peace deal, the US Energy Information Administration's June 2026 Short-Term Energy Outlook assumed the Strait of Hormuz would remain effectively closed into early summer. Under that assumption, the EIA projected Brent would average $105 per barrel in June and July. Brent now trades 22% below that forecast. Full oil production and trade normalization will not arrive until early 2027, the EIA projects.

Rystad Energy's Claudio Galimberti projects that roughly 85% of lost Gulf volumes will return by October 2026. Capital Economics forecasts 80% of prewar energy flows by September. Both scenarios leave 15 to 20% of prewar supply volumes offline through at least the end of 2026.

Wood Mackenzie's Alan Gelder focused specifically on Iraq, the second-largest OPEC producer. "It may well take about a year before they get back," Gelder said, referring to Iraq's ability to restart shut-in production. Iraq's upstream infrastructure requires sustained power supply and wellbore pressure management, both of which deteriorate during extended shutdowns.

Kpler's Amena Bakr provided the most granular breakdown. Mine clearance alone will require six months, she said. Vessel departure and fleet repositioning in the Gulf will add two to three more months. Restarting production in countries that shut in fields takes another three months on top of that. Accumulated sequentially, Bakr's framework stretches full normalization toward late 2027 at the upper end.

Physical Barriers That a Signature Does Not Clear

The US government has stated that mine clearance in the Strait of Hormuz will require approximately six months. This is a naval logistics constraint tied to sweep patterns and verification protocols, not a diplomatic one. Until an independent authority certifies safe corridors, commercial operators and their insurers will not authorize vessel transits.

Insurance is the second obstacle. The International Group of P&I Clubs, which covers roughly 90% of the world's ocean-going tonnage, cancelled war-risk policies for Gulf-transiting vessels effective midnight on March 5, 2026. War-risk premiums remain at multiples of prewar rates, as underwriters require verified safety data before reducing pricing. Those policies do not restore automatically when a peace agreement is signed.

Lloyd's Market Association confirmed this week that cover for Gulf transits remains available, but at elevated cost. Richard Meade of Lloyd's List stated: "Operationally, the sector is not rushing back." Mine clearance and transit-lane restoration "are prerequisites for safe navigation," Meade said. An estimated 118 tankers could begin transiting within 15 days of safe-corridor confirmation, but that confirmation remained outstanding as of Monday.

The Price Gap Between Market Sentiment and Physical Reality

Brent fell from $111.91 per barrel one month ago to $81.55 as of Monday morning, a decline of $30.36, or 27.1%. At current levels, crude has unwound the entire Hormuz war premium and is trading near pre-conflict lows. The market has effectively priced a swift and complete recovery.

Bundesbank President Joachim Nagel stated that "it will take months for the oil supply to return to normal." Capital Economics' September scenario, the second-most-optimistic forecast reviewed here, has flows reaching only 80% of prewar levels by that point. The EIA estimated Gulf production shut-ins averaged 11.3 million barrels per day in May 2026, meaning a 20% shortfall still represents more than 2 million barrels per day of supply missing from world markets at that stage.

OPEC+ members that were unable to pump through the Hormuz closure will push to restore lost market share once the strait reopens. That competition among Gulf producers, combined with Kazakhstan's persistent overproduction above quota, means OPEC+ supply dynamics in the second half of 2026 may diverge substantially from what current prices imply. The OPEC+ Joint Ministerial Monitoring Committee will be the first official body to signal how the group intends to manage the supply transition.
