On Tuesday, May 26, 2026, the U.S. military conducted “self-defense strikes” in southern Iran near the Strait of Hormuz, targeting missile launch sites and vessels attempting to deploy mines, according to U.S. Central Command (CENTCOM). The attacks occurred as an Iranian delegation, led by Foreign Affairs spokesman Esmaeil Baghaei, prepared to negotiate a ceasefire in Qatar, compounding tensions amid ongoing diplomatic efforts to end the U.S.-Iran conflict. The strikes, which triggered explosions in Bandar Abbas, 70km from the strategic waterway, have raised questions about the viability of the Pakistan-mediated ceasefire that has held since April 8. <a href="https://www.aljazeera.
U.S. Justifies Strikes as Self-Defense, Iran Reports Drone Downing
CENTCOM spokesperson Navy Captain Tim Hawkins stated the strikes were aimed at “protecting our troops from threats posed by Iranian forces,” without specifying locations. The U.S. accused Iran of laying mines in the Strait of Hormuz, a critical global energy chokepoint through which a fifth of the world’s oil and gas flows. Iranian media reported explosions in Bandar Abbas, while the Islamic Revolutionary Guard Corps (IRGC) claimed to have downed a “hostile” stealth drone using a new air defense system. Al Jazeera The IRGC also alleged it had targeted a vessel at sea before the U.S. strikes, though no official Iranian response has been released.
Diplomatic Stalemate as Trump Warns of “Great Deal or No Deal”
U.S. Secretary of State Marco Rubio, who was in India at the time, emphasized the strategic importance of keeping the Strait of Hormuz open “one way or the other.” However, he cautioned that negotiations with Iran “could take a few days,” tempering hopes for an imminent resolution. President Donald Trump, meanwhile, tweeted that talks were “proceeding nicely” but warned that the U.S. would resume military action if negotiations collapsed. “It will only be a Great Deal for all or, no Deal at all,” he wrote, reflecting his hardline stance. Al Jazeera The White House has not confirmed whether a memorandum of understanding with Iran is still in negotiation.

Oil Markets React to Escalating Tensions
Global oil prices surged as traders braced for further disruptions. July Brent crude futures rose 3.3% to $99.33 a barrel, while U.S. West Texas Intermediate (WTI) futures fell 4.1% to $92.79, partly due to the Memorial Day holiday. The U.S. military’s strikes and Iran’s threat to retaliate against ceasefire violations have intensified fears of supply shocks. Swiss bank UBS warned that global oil inventories have dropped by 246 million barrels in March and April, with production losses potentially exceeding 1 billion barrels by May. “The market remains strongly undersupplied,” the bank said, citing declining on-land inventories despite increased tanker storage.
Conflict Escalation: Ceasefire vs. Military Action
The timing of the strikes has raised doubts about the durability of the ceasefire. Iran’s IRGC claimed it would retaliate for “violations of the ongoing ceasefire,” citing encounters with U.S. drones and an F-35 jet. The U.S. has not confirmed these claims, but CENTCOM reiterated its commitment to “defend our forces while using restraint.” Meanwhile, Trump’s push for broader Middle East alliances, including encouraging Arab nations to join the Abraham Accords, has complicated diplomatic efforts. Al Jazeera The lack of an immediate Iranian response suggests either internal deliberation or strategic restraint, but both sides appear locked in a high-stakes standoff.

What Comes Next? A Delicate Balance
The next 48 hours will be critical. If the Iranian delegation in Qatar can secure a deal, it may de-escalate tensions. However, the U.S. strikes and Trump’s rhetoric suggest the administration is prepared to maintain pressure. For oil markets, any further disruption to the Strait of Hormuz could push Brent crude past $100 a barrel, worsening global inflation. Analysts warn that the conflict’s resolution hinges on whether diplomacy can outpace military posturing. As one UBS strategist noted, “The market is on edge, and the clock is ticking.” CNBC The
