Oil futures moved in opposite directions on May 26 as U.S. military strikes in Iran clouded peace negotiations and kept the Strait of Hormuz shipping corridor closed. Brent crude climbed 4% to $99.58 per barrel while WTI fell 2.81% to $93.89. The conflicting signals reflect investor uncertainty about whether a deal will materialize and when tanker traffic will resume through one of the world’s most critical energy chokepoints.

Military Strikes Reignite Geopolitical Risk

The U.S. conducted what it called “self-defense” strikes on Iranian targets early Tuesday, hitting missile launch sites and Iranian boats attempting to place mines in the Strait of Hormuz. The strikes came just hours after President Trump said negotiations with Iran were “proceeding nicely.” U.S. Secretary of State Marco Rubio said talks could “take a few days” to complete, signaling no immediate resolution. Analysts at energy markets warned that military activity continues to create uncertainty despite diplomatic progress.

Strait Remains Blocked, Supply Concerns Mount

The Strait of Hormuz handles 35% of global crude oil and 20% of natural gas supplies. Tanker traffic fell 95% from pre-crisis levels and remains severely restricted. Some LNG cargoes and a supertanker carrying Iraqi crude that had been stranded for three months recently passed through, but shipping remains limited. Reports suggest Iran could agree to clear mines within 30 days under a broader deal, but any reopening would happen gradually rather than immediately, prolonging supply chain disruptions into summer.

Price Volatility Reflects Deal Uncertainty

Brent crude rose more than 2% following the latest military strikes, even after prices had fallen sharply on ceasefire hopes. WTI traded near $93 per barrel as of early May 26 trading. Market participants remain divided on whether the remaining 5% of a deal will be resolved. Key sticking points include Iran’s willingness to surrender enriched uranium and reopen the Strait free of Iranian control or transit fees. The Revolutionary Guard’s resistance suggests negotiations could stretch into another 60-day ceasefire rather than a final agreement.

Energy Sector Impact and Market Reaction

The International Energy Agency called the Hormuz conflict the most significant oil shock in history, with damage to 80 energy facilities totaling at least $25 billion and loss of 13 million barrels per day of exports. Oil-linked stocks fell on May 26, with energy companies like Exxon Mobil and EOG Resources down 1.43% each in premarket trading. Broader markets rallied on peace deal optimism, with the S&P 500 and Nasdaq hitting record highs, but energy investors remain cautious about supply recovery timing.

Final Thoughts

Brent crude’s 4% jump to $99.58 signals continued geopolitical risk despite peace talk progress. With the Strait of Hormuz still blocked and key deal terms unresolved, oil prices will likely remain volatile until shipping actually resumes.
