Exxon Warns Oil Markets Mispricing Hormuz Closure Risk as Derivatives Show Complacency
CEO Darren Woods says markets haven't absorbed the full impact of the strait disruption, even as global supply has fallen 10.1 million barrels per day and Trump pauses escort operations.
Exxon Mobil’s leadership warned that global oil markets are structurally underpricing the geopolitical risk of extended Strait of Hormuz closure, even as the waterway’s blockade has triggered what the International Energy Agency calls the largest supply disruption in the history of the global oil market.
The warning came during Exxon’s Q1 2026 earnings call on May 1, when CEO Darren Woods told investors that Derivatives markets and spot curves show dangerous complacency about closure duration risk. “It’s obvious to most that if you look at the unprecedented disruption in the world supply of oil and natural gas, the market hasn’t seen the full impact of that yet,” Woods said, according to CNBC. “There’s more to come if the strait remains closed.”
The strait, which facilitates transit of roughly 20 million barrels per day representing 20% of global seaborne oil trade, has been effectively closed since Iran blockaded the waterway on March 4 following Operation Epic Fury airstrikes that killed Supreme Leader Ali Khamenei. Global oil supply plummeted by 10.1 million barrels per day to 97 mb/d in March, per the IEA, with crude oil flows dropping 95%, LNG by 99%, and fertilizer-related cargoes by 87% according to WTO vessel-tracking data.
Market Complacency Despite Historic Disruption
Brent crude rose nearly 6% to close at $114.44 per barrel on May 5, with West Texas Intermediate advancing more than 4% to $106.42, according to CNBC. Yet Exxon’s assessment suggests these levels dramatically understate tail risk if the closure extends beyond Q2 2026.
Modeling by the Dallas Federal Reserve projects a cessation of oil exports from the Persian Gulf lasting one quarter would raise average WTI prices to $110 per barrel in April 2026, while a two-quarter outage would cause WTI to peak at $132 per barrel in July. These scenario models appear conservative given current spot pricing already exceeds the one-quarter disruption forecast.
“The market is pricing oil higher as it factors in the risk of more oil infrastructure damage and the likelihood that the Strait of Hormuz will be shut beyond the timeline that the Trump administration has laid out.”

Exxon warned its production in the Middle East would decline by 750,000 barrels per day compared with 2025 if the strait remains closed through Q2, with throughput to global refiners falling 3% compared with Q4 2025. The company’s guidance suggests commercial and strategic reserves are depleting faster than derivatives markets are pricing, creating a structural gap between geopolitical reality and financial market preparedness.
Trump Pauses Escort Operations Amid Negotiations
President Trump announced on May 5 he was pausing Project Freedom vessel escort operations to focus on Iran negotiations, citing “great progress” toward a complete agreement. The decision came as Secretary of State Marco Rubio disclosed that nearly 23,000 sailors on vessels representing 87 countries remain stranded in the Persian Gulf, with at least 10 sailors already dead due to strait conditions.
“They’re sitting ducks. They’re isolated, they’re starving, they’re vulnerable, and at least 10 sailors have already died as a result,” Rubio said, per CNBC. Iranian Foreign Minister Abbas Araghchi dismissed the escort initiative, calling it “Project Deadlock” in comments to NBC News.
The diplomatic pause creates dual risk vectors for energy markets. A successful negotiation could trigger rapid de-escalation and strait reopening, potentially collapsing risk premiums embedded in forward curves. Conversely, negotiation failure would expose the market’s current complacency, potentially triggering violent repricing in energy derivatives and inflation expectations as commercial reserves deplete without replenishment.
Insurance Markets Signal Persistent Risk
War-risk ship insurance premiums for strait transit increased from 0.125% to between 0.2% and 0.4% of ship insurance value per transit in the days before the February 28 strikes. These levels remain elevated despite Trump’s negotiation optimism, suggesting underwriters are pricing continued disruption risk beyond official administration timelines.
The Strait of Hormuz has been a geopolitical flashpoint for decades, with previous disruption scares in 2012 (Iranian closure threats during nuclear negotiations) and 2019 (tanker attacks) causing temporary price spikes. However, the current closure represents the first sustained blockade in modern history, dwarfing all previous disruptions in magnitude and duration. The IEA’s characterization as the largest supply disruption ever recorded reflects both the strait’s critical role in global energy flows and the unprecedented nature of the Iran-US military confrontation.
The March 2026 supply loss of 10.1 million barrels per day exceeds the combined spare capacity of OPEC+ members, meaning any extension of the closure beyond Q2 cannot be offset through increased production elsewhere. This structural constraint explains Exxon’s warning that markets haven’t absorbed the full impact — peak demand destruction from $200+ oil scenarios remains unpriced in options markets, creating asymmetric tail risk.
What to Watch
Monitor Trump-Iran negotiation progress for signs of breakthrough or breakdown, which will determine whether current spot prices represent a peak or a floor. Watch commercial crude inventory data from the US Energy Information Administration and IEA for depletion rates that could accelerate price discovery if talks fail. Track options volatility in Brent and WTI futures for shifts in implied probability of extended closure scenarios. Any resumption of military operations or attacks on stranded vessels would likely trigger immediate repricing toward Dallas Fed’s $132 two-quarter closure scenario, while successful negotiation could see rapid unwinding of risk premiums as strait transit resumes.
