Oil rises after reports of US strikes on Iran dampen hopes for Hormuz reopening

Fresh reports of U.S. strikes in southern Iran push crude prices higher despite earlier signs of a deal to reopen Strait of Hormuz

By Priya Menon

Oil prices climbed in early Asian trading after reports that the United States carried out new attacks targeting missile launch sites and mine-laying vessels in southern Iran. The moves undercut earlier market optimism that a framework deal to reopen the Strait of Hormuz was imminent and follow a sharp decline in Brent on Monday. Key price benchmarks were higher, while uncertainty over diplomatic progress and Tehran's response to the strikes persisted.

Oil rises after reports of US strikes on Iran dampen hopes for Hormuz reopening

Key Points

  • Brent futures for July rose nearly 2% to $97.84 a barrel in early Asian trade.
  • WTI futures gained 1.2% to $91.40 a barrel; WTI did not settle on Monday because of a U.S. market holiday.
  • Reports that the U.S. struck missile launch sites and mine-laying boats in southern Iran offset earlier reports of a framework deal to reopen the Strait of Hormuz.

Oil benchmarks firmed in early Asian trade as reports circulated that the U.S. had launched fresh strikes against targets in southern Iran, undercutting earlier optimism that a deal to reopen the Strait of Hormuz was close.

By 20:03 ET (00:03 GMT), Brent futures for July were trading up nearly 2% at $97.84 a barrel, while West Texas Intermediate futures gained 1.2% to $91.40 a barrel. WTI had not settled on Monday because U.S. markets were closed for a holiday.

Markets had reacted sharply the previous session after reports suggested a framework agreement between the U.S. and Iran to end hostilities and reopen the vital Gulf waterway, with Brent falling almost 3% on Monday. That decline was, however, constrained by a lack of clarity about the situation.

On Monday evening, media reports said U.S. forces struck missile launch sites and mine-laying boats in southern Iran. The U.S. military described the strikes as actions taken in self-defense and said a ceasefire with Iran remained in place.

Tehran's immediate reaction to those reported strikes was not clear. Observers noted that any fresh military activity would complicate the ongoing negotiations between the two nations, particularly given repeated Iranian warnings against further attacks.

Earlier commentary from the U.S. president had suggested progress in negotiations with Iran and included a claim that Tehran would relinquish its holdings of enriched uranium. Iran has largely denied plans to hand over its uranium, although reporting indicated the country was open to eventual talks over its nuclear activities.

The renewed reports of military action largely offset the wave of optimism that had driven Monday's deepening sell-off. With both diplomatic signals and on-the-ground events sending mixed messages, crude markets remain sensitive to updates from the Gulf and statements from the parties involved.


Summary
Reports of new U.S. strikes in southern Iran lifted crude prices in early Asian trade, reversing some of the market's earlier optimism after reports that a framework deal to reopen the Strait of Hormuz was near. Brent and WTI both rose, while uncertainty about Tehran's response and the future of negotiations persisted.
